Material Features

Alloy Steel:

A steel, other than a stainless steel, that conforms to a specification that requires one or more of the following elements, by mass percent, to have a minimum content equal to or greater than: 0.30 for aluminum; 0.008 for boron; 0.30 for chromium; 0.30 for cobalt; 0.40 for copper; 0.40 for lead; 1.65 for manganese; 0.08 for molybdenum; 0.30 for nickel; 0.06 for niobium (columbium); 0.60 for silicon; 0.05 for titanium; 0.30 for tungsten (wolfram); 0.10 for vanadium; 0.05 for zirconium; or 0.10 for any other alloying element, except sulphur, phosphorus, carbon, and nitrogen.

Low-alloy Steels pipe:

A steel, other than a carbon steel or an interstitial-free steel, that conforms to a specification that requires the minimum content for each specified alloying element to be lower than the applicable limit in the definition for alloy steel.
As with steels in general, low-alloy steels can be classified according to:
– Chemical composition, such as nickel steels, nickel-chromium steels, molybdenum steels, chromium-molybdenum steels
– Heat treatment, such as quenched and tempered, normalized and tempered, annealed.

High-Strength Low-Alloy Steels pipe: 

The HSLA steels have low carbon contents (0.05-0.25% C) in order to produce adequate formability and weldability, and they have manganese contents up to 2.0%. Small quantities of chromium, nickel, olybdenum, copper, nitrogen, vanadium, niobium, titanium and zirconium are used in various combinations

Why choose steel pipe bollards

Steel posts are one of the simplest, most cost-effective ways to offer protection for buildings and pedestrians from vehicle collisions, as both a physical and visual barrier. Steel bollards can be installed in any surface, indoors or outdoors, to prevent entry from errant vehicles, secure vulnerable areas, and protect site assets.

As the population, especially in urban centers, continues to grow, so too does the number of vehicles on the road. With the increase of drivers and cars in and around cities, the likelihood of accidents and collisions has gone up as well. Properly planned parking lot design and the installation of security bollards can reduce these risks, create a safe pedestrian environment, and increase overall security.

Versatile security pipe bollards

Security pipe bollards aren’t limited to a specific type of application. They will protect pedestrians and properties from vehicle crashes—accidental or otherwise. Steel pipe bollards can be easily installed in most locations or ground surfaces, for a range of applications.

Steel pipe bollards, shown here before installation, calm traffic and safeguard people and property.
Galvanized pipe is coated with zinc and metal. This makes them more durable than
older pipes which were crafted from steel or iron. These pipes also have added protection,
because the coating of zinc prevents issues with corrosion.

Galvanized Steel Pipe Bollards

Building protection

Cars aren’t just colliding into people. Crashes into structures and buildings happen at a high rate. According to researchers at the Storefront Safety Council, more than 60 vehicles crash into buildings every day, leading to 3,600 injuries per year. Further injuries can be caused indirectly from the damage to the building itself, such as collapsing buildings, trapping people under building rubble and in vehicles, and fires from damaged electrical wires and equipment. In addition to safety issues, vehicle crash damage can cause temporary or permanent closures, as well as financial or insurance complications. Security bollards create a physical and visual barrier to ensure vehicles keep away from buildings and other sensitive areas.

steel pipe posts protect a pad-mounted transformer
Steel pipe bollards protect sensitive property, such as utilities.

Galvanized Steel pipe bollards is used in outdoor and indoor applications due to its anti rusting components.
The zinc coating slows the process of corrosion and can make the pipe last for decades (in the right environment). This makes it ideal for marine applications and for transporting hot and cold water alike. Galvanized Steel pipe bollards isn’t perfect for every type of job though. There are disadvantages
to using galvanized pipe with gas lines and are not typically used in underground applications.

Size:
Round pipe: 1/2″ – 20″
Spiral pipe: diameter 219-1420mm

Wall Thickness: 1.4-14mm
Length: 2-12m according to customers’ requirements
Zinc coating: 275-350g/m² standard
Type: welded pipe/seamless pipe/cold drawn seamless tube

Electronic fusion welded (EFW)
Double submerged arc welded (DSAW)

Galvanized Steel pipe bollards have a longevity, are cost effective, and are low maintenance. They can be inspected with a trained eye and are easily assembled. For all your Galvanized Steel pipe bollards needs, choose a professional who has the experience you need.

Parking lot safety

Parking lots are another common location of car crashes. With drivers focused on finding empty parking stalls, cars backing in and out and turning spontaneously, and pedestrians walking in and around cars, accidents, though usually not severe, are frequent. Security bollards can protect pedestrian areas from intruding cars without limiting foot traffic.

Warehouses

Vehicles aren’t only outdoors. Warehouses often use forklifts to move shipments in tight spaces, and even when moving at slow speeds, forklift collisions can cause serious injuries. Warehouse pipe bollards clearly define pedestrian areas in a working environment, and create a barrier around sensitive structures such as shelf corners and loading docks.

Why choose steel pipe bollards

Steel posts are one of the simplest, most cost-effective ways to offer protection for buildings and pedestrians from vehicle collisions, as both a physical and visual barrier. Steel bollards can be installed in any surface, indoors or outdoors, to prevent entry from errant vehicles, secure vulnerable areas, and protect site assets.

Steel pipe bollards painted with primer in bundle on skid
Steel bollard pipes are made from ASTM 500 B structural grade steel. These pipes have been primed for paint.

Steel pipe bollards are made from structural grade steel, which is reinforced with and embedded in concrete for added strength. Made from ASTM 500 B structural grade steel, pipe bollards are best installed in new concrete surfaces, but can also be installed using concrete forms or in existing concrete, though they will provide less strength. Steel pipe posts can be cut to custom lengths, and are available in a range of colors to add visibility or complement the building’s design or branding.

Bollard covers for design appeal

While they provide security and traffic control functionality, steel pipe bollards can be unsightly. Without powder coating or covers, metal posts are also vulnerable to rusting, especially in rainy areas and near the ocean. While paint provides some protection, it requires yearly reapplication. If a bollard post is left untreated, temperature and moisture can cause rust and weaken the bollard over time.

Stainless steel bollard covers with reflective strips outside a hospital
Stainless steel bollard sleeves cover pipe bollards to add style to security.

To improve both aesthetics and durability, plastic, stainless steel, and decorative metal bollard covers are available. Bollard covers, or sleeves, provide easy-to-install, cost-effective protection for steel pipe bollards, by covering the outside of the post with a more durable material, and preventing exposure to rain, snow, ice, and deicing salts or fluids. Decorative bollard covers come in a wide variety of designs, enhancing a landscape’s visual appeal instead of detracting from it. Bollard sleeves can also increase the visibility of steel pipe posts—some covers can be equipped with reflective strips, further helping drivers notice the bollard.

From high-traffic parking lots, to vulnerable indoor areas, steel pipe bollards work as a safeguard for site users and assets. In locations where accidental collisions may occur, bollards can provide peace of mind for site owners and pedestrians alike.

Note: Several installation factors will affect the protective capacity of steel pipe bollards. Bollard dimensions, installation materials and surrounding site conditions affect the amount of force a bollard can withstand. Consult an engineer to identify suitability and installation requirements for specific site applications.

Carbon steel Hot Rolled Seamless Pipe

 

The advantages and disadvantages of hot-rolled steel pipe and cold-rolled steel pipe are described below.

Hot rolled
Advantages: It can destroy the casting microstructure of the ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved.

This improvement is mainly reflected in the rolling direction, so that the steel to a certain extent is no longer isotropic body, the formation of the pouring bubble, crack and loose, can also be welded under the action of high temperature and pressure.

Shortcomings: 1. After hot-rolling, non-metallic inclusions in the steel (mainly sulfide and oxides, as well as silicate) are pressed into thin slices, the phenomenon of delamination (interlayer) occurs. Delamination greatly worsens the tensile properties of the steel along the thickness direction, and it is possible to have interlayer tearing during the contraction of the weld.

The local strain induced by the weld contraction often reaches several times of the yield point strain, which is much larger than the strain caused by the load. 2. Residual stress caused by uneven cooling. Residual stress is the internal self equilibrium stress in the absence of external force, and all kinds of hot-rolled steels have such residual stresses, the larger the general section size of steel and the greater the residual stress. Although the residual stress is a self equilibrium, it has some influence on the performance of the steel member under the external force.

such as deformation, stability, anti-fatigue and other aspects may have adverse effects.

 

Cold Rolled

Cold rolling refers to the steel plate or steel strip processed into various types of steel by cold drawing, Leng, drawing and so on at room temperature.

Advantages:

Rapid molding speed, high yield, and no damage to the coating, can be made into a variety of cross-section forms to meet the needs of the use of conditions;

Shortcomings:

Product description
ASTM A53 /a 106 Carbon Cold Drawn/Hot Rolled Seamless Steel Pipe

Carbon steel cold  Rolled Seamless Pipe

Application

1.  Low and middle pressure fluid transportation pipeline
2.  Casing Tube
3.  Boiler Pipe
4.   Petroleum and natural gas industry
5.  Chemistry industry
6.  Electric industry

 

1. Although the molding process has not undergone thermal plastic compression, but there is still residual stress in the section, the overall and local buckling properties of steel will inevitably have an impact. 2. The cold rolled section style is generally open section, which makes the free torsional stiffness of the section lower.

It is easy to twist when bending, bending and torsional buckling is easy to appear under pressure, and torsional performance is poor.

3. Cold-rolled steel wall thickness is small, the joint of the plate is not thickened at the corner, the ability to withstand local concentrated load weak.

Three. The main differences between hot and cold rolling

1. The partial buckling of the allowable section of cold rolled steel can make full use of the buckling load of the rod, while the hot-rolled steel section does not allow local buckling. 2, the reasons for the residual stress of hot rolled and cold rolled steel are different, so the distribution on the section is also very big difference.

The residual stress distribution of cold-formed thin-walled steel section is curved, while the residual stress distribution on hot-rolled or welded section is film type.
3. The free torsional stiffness of hot rolled steel is higher than that of cold-rolled steel, so the torsion resistance of hot rolled steel is better than that of cold-rolled steel.

Usage for 3PE welded steel pipe

Must be the first material, thick plate commonly used cutting methods are plasma arc cutting, laser cutting, oxygen gas flame cutting, carbon arc air planing, water jet melting pole arc cutting method and the latest water jet cutting method. 3PE corrosion-resistant steel tubes with relatively small thickness are usually cut by shearing machine in the past more than 20 years, the rapid development of China’s iron and steel industry, thanks to the urbanization and industrialization of our country, now, the new concept of urbanization, the direction of urbanization has been established, no doubt for the future of steel industry to create unlimited space for development,The steel industry has a long way to go in the future of the new industrialization and the urbanization. There are many ways and tools to look at individual choices. Personal skills are also one aspect.

In the same time as the 3PE anti-corrosion steel pipe Cutting, we use a general cutting machine can also be carried out. In order to ensure that the pipeline processing is not deformed the most important thing is to choose to meet your welding requirements of the cutting machine, cutting machine is not the same, cutting the way will not be the same, there are other ways.

Now commonly used in the domestic mechanical cutting, flame cutting and water cutting these several ways, these three ways to ensure that the pipeline does not deform. 1. Mechanical cutting using external installation and internal installation of two kinds, and its use of lathe knife processing principle of cutting and groove processing, single machine span large, machinable thickness, waste less, non-polluting, processing process does not produce high temperature, does not affect the pipeline material, is conducive to welding.

Water cutting through high-pressure pump and emery together to process the pipeline, its incision clean, processing span is large, but its efficiency is low, processing thickness limited factors.

2. Oxygen acetylene flame cutting, by regulating oxygen valves and acetylene valves, can change the mixture of oxygen and acetylene to get three different flames: Neutral flame, oxidizing and carbonized flame. 3. Ion cutting, plasma cutting with different working gas can cut all kinds of oxygen cutting hard to cut metal, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel) cutting effect better; The main advantage is that the cutting thickness of the metal, plasma cutting speed, especially in cutting ordinary carbon steel sheet, the speed can reach the oxygen cutting method 5~6 times, the cutting surface is smooth, the heat deformation is small, the heat influence area is few. These methods are also commonly used in pipe cutting.

Pipe must choose the appropriate cutting tools, otherwise it is easy to cause damage to the pipe waste.

The aging of steel tubes has prompted the birth of anticorrosive steel pipes:

As carbon steel pipes age, they become subject to wear and tear. They develop weak spots, which can result in small leaks throughout the system. They can also gradually become unsafe, and eventually a failure may occur, causing flooding and water damage over a large area. This can happen both throughout a home, as well as throughout commercial, industrial, and high rise buildings.

When this type of damage occurs, it can be expensive, time-consuming, and disruptive to fix. carbon steel Pipes must be dug up and replaced. When that occurs, the entire system becomes at-risk for new breakages and weak spots, leading to further failures and leaks that must then be addressed.

In potable water lines, epoxy is blown into cleaned carbon steel pipes, forming a safe, evenly coated barrier between metal pipe walls and water.

The epoxy lining provides a durable and long lasting solution to leaks, broken carbon steel pipe, slow drains, and blockages. The new lining increases water flow rate and water quality while it prevents carbon pipe erosion, water damage from leaks and mold growth. The epoxy keeps out heavy metals and corrosion that normally leaches into drinking water from metal steel pipes.

At ABTER STEEL, we understand that you do not want your plumbing to disrupt your life. That is why we offer carbon steel pipeline coating solutions that are safe, effective, and affordable for restoring your plumbing system. Our solutions are applied by skilled carbon steel pipe liners throughout the WORD area.

What is the Pipe Coating anticorrosive Process?

An effective epoxy coating process begins with walk through to determine the problem areas and pipe configuration. A plan is implemented to minimize disruption and afford the most efficient timeline for work completion. The piping system is also inspected for integrity and spot repairs from excessively worn joints and fittings. A temporary bypass water pipe may be installed.

After pipe mapping and spotchecking is completed, pipes are dried with heated, compressed air. A safe abrading agent is blown through the pipe system, removing rust and corrosion by-products that are collected in a holding unit for disposal. Compressed air is applied once again to remove fine particles.

The epoxy coating is applied to the pipes using conditioned air to uniformly distribute the epoxy throughout the pipe segment.

Optimal internal pipe surface temperature is created prior to epoxy coating. Another air pressure leak test is performed. Conditioned air is then introduced into the pipe to uniformly distribute the epoxy coating throughout the pipe segment. Following the coating application, continuous controlled air flows through the piping to facilitate epoxy curing.

Following the coating application, continuous controlled air flows through the pipes during the epoxy curing process.

When the epoxy cures, valves and couplings are refitted and a final leak test confirms the integrity of the line. In addition, water quality, volume and flow tests confirm the functionality of the system.

Pipe lining and epoxy coating provides a non-disruptive, time efficient and cost effective solution in comparison to traditional pipe replacement. Used for both non-pressurized pipes such as sewer and vent stacks and pressurized pipe systems such as potable and fire suppression, pipe lining and epoxy coating is not just a band aid fix but a long term solution.

After the epoxy coating cures, valves and couplings are refitted. A final leak test and inspection confirms lining integrity. Water quality, volume, and flow tests confirm system functionality.

Automatic ultrasonic testing, refers to the use of mechanical devices to
automatically move the probe or the inspection of the workpiece to achieve
automated scanning, in the mobile process can be used in different ways to
stimulate different wave type of ultrasonic, as well as the use of different
coupling methods to detect the defects in the detected workpiece automated
detection, The test results can be automatically recorded in a specific
recording medium (such as pen-type record paper tape, electric-sensitive
records, computer storage equipment, etc.), but also can be automatically
labeled (painting, printing, etc.) on the workpiece, but also qualified and
unqualified workpiece for automatic sorting and so on.

Automatic ultrasonic testing system also usually has monitoring devices (such as
oscilloscope, flaw detector screen, computer monitoring screen, etc.), to
facilitate the detection of personnel according to the detection signal
monitoring system work is normal.

Automatic ultrasonic testing system can be divided into two main categories:

1. On-line automatic ultrasonic testing system This is in the automatic
production line as an inspection process (station) implementation, it is not
only to judge whether the workpiece is qualified or not, and automatically
select or mark (spray), and its detection speed, the continuous running time of
the testing system, the working conditions (such as high temperature, vibration,
Noise and so on) adaptability and detection system self-protection, etc., must
be suitable for automatic production line high-speed, stable and reliable
requirements.

2. Off-line (not online) automatic or semi-automatic ultrasonic testing system
this is in the production process as a separate inspection process, it can be
divided into automatic and semi-automatic two types.

1) Not on-line automatic ultrasonic testing system except the sensitivity
adjustment and machine maintenance of all the work step, for example, access
materials, defects alarm and records, marking, the material seized and the
separation of the waste and sorting are all rely on the equipment itself
automatically, such as the current domestic many large enterprises have been in
the application of automatic ultrasonic testing system, described above The
automatic ultrasonic inspection system for API 5l ERW pipe off-line automatic
ultrasonic testing system, seamless steel tube and bar, billet, etc.

2 not on-line semi-automatic ultrasonic testing system it’s working procedures
in a part or several parts of the need for manual completion, such as the
material or workpiece to be checked and loading and unloading, defects and other
indicators. For example, the aviation industry in the turbine disk, compressor
disk and other disk-shaped parts and beam parts of the semi-automatic water
immersion ultrasonic flaw detection system.
With the development of scientific and technological progress, the domestic
ultrasonic flaw detection has been most of the use of automated testing, the
main advantages of automatic testing are: Because of the use of mechanical
devices to make ultrasonic probes with the material or workpiece automatically
relative motion, compared with manual detection, can ensure sound coupling
performance is relatively stable; Large inspection area, fast speed, high
efficiency, can automatically record detection results and make objective record
and mark, to avoid operator’s human factors and subjective judgment error, to
ensure consistency of detection results, but also greatly reduce the labor
intensity of operators.

The limitation of automatic testing is: To carry out automatic testing of
materials or workpiece must have a clear section and the determination of waste
(rejection) standards, testing results of the repeatability of better, othAPI 5l ERWise
prone to miscarriage or missing. In order to ensure the accuracy and reliability
of automatic testing equipment, it is necessary to make the equipment have
sufficient anti-interference performance and often in good working condition,
which requires the high structure precision and stable operation of the
mechanical device to ensure the stability of detection sensitivity.

It should be pointed out that a very important indicator of automatic detection
is its detection speed, that is, the relative moving speed between the probe and
the material or workpiece is appropriate to ensure that the probe launched by
the beam to be detected enough to cover the object, not missing. Also, make sure
that the probe has sufficient time to detect the object in the moving state, the
ability to obtain sufficient strength of the defect signal and sufficient to
determine the number of defects signal repetition (generally requires a defect
echo signal in the probe and the workpiece relative to the movement of the
scanning process repeated at least 2~3 times), This depends on the type of
defect that is required to be detected, the orientation and size as well as the
acoustic field characteristics and directivity of the probe are considered
synthetically, and it is closely related to the ultrasonic pulse repetition
frequency, the response frequency of the alarm or recording system, the response
time and the geometrical dimension (such as thickness) of the object.

In addition, with the rapid development of automation technology, especially
electronic technology, the development trend of automatic ultrasonic testing
system is facing with micro computer or industrial control machine, realizing
intellectualization, improving signal processing ability, realizing data
processing automation, including the recognition judgment of flaw nature, defect
size, Defect density and occupancy rate (percentage of projected area or volume
of defects in a certain area or space), the defect distribution position and the
defect shape judgment and so on, thus the quality of the object is evaluated, in
order to further improve the reliability, accuracy and efficiency of the
automatic ultrasonic testing technology and equipment.

Classification of automated Ultrasonic testing methods:

(i) Classification by sound coupling method

(1) Direct contact method in automatic ultrasonic testing, the direct contact
method is seldom used, because the acoustic coupling between the probe and the
object being detected is not easy to achieve uniform stability, which affects
the detection result (stability of detection sensitivity), however, if the
specimen surface finish is higher, or the required detection speed is not very
fast, when the use of appropriate coupling agent and the use of such as
compression spring or plate and other institutions, it is also possible to
achieve direct contact testing of rail, spiral welded pipe welds, seamless
tubes, and so on, of course, when using this method, the probe clamping and
moving mechanisms are often more complex.

(2) Local liquid leaching method is the most commonly used coupling method in
automatic ultrasonic testing system, and it can be divided into three kinds:

1 Spray method: The probe is installed in the nozzle, the water into the nozzle
in the form of uniform spray to the surface of the material being detected to
achieve sound coupling. This method has been applied to the multi-channel (up to
dozens of or even hundreds of channels) of the medium-thickness steel plate by
Automated ultrasonic penetration method on-line or off-line detection, as well
as in the aerospace industry for the aircraft vertical tail, horizontal tail,
wing and other composite components of the automatic ultrasonic penetration
method detection.
2) Overflow Water Law: in the lower part of the test materials installed
overflow tank, probe device in the tank, from the bottom of the emission of
ultrasonic beam into the test material, the material in the feed moving in the
process of contact with the overflow, forming sound coupling conditions. This
method is commonly used in the automatic ultrasonic reflection method of large
diameter rods or tubes, which can be focused on line or even phased array
probes.

3 through the local water immersion method: The test material through the water
seal device through the tank, probe device in the upper part of the tank, from
the bottom of the emission of ultrasonic beam into the test material, can also
be installed in the lower part of the tank, from the lower to the launch of
ultrasonic beam into the test material This method is commonly used to detect
the automatic ultrasonic reflection method of small diameter pipe or bar, and is
usually focused on the water immersion point.
(3) The whole liquid leaching method is used in semi-automatic testing system,
the material is immersed in the water, so it needs a larger tank, the probe is
placed in the upper part of the tank, and the ultrasonic beam is sent down from
the top to the test material. This method is commonly used for semi-automatic
detection of disc-shaped or cake-shaped forgings by ultrasonic reflection
method.
