The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe. This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil. Size range is limited only by manufacturer’s capabilities. Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries. The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore […]
API-5CT N80 oilfield casing pipe contains N80-1 and N80-Q types. Those two materials are absolutely consistent regarding the chemical composition and mechanical attributes, they are just various in the heat treatment. During heat treatment, N80-1 steel is treated by normalizing and tempering, while N80Q steel is treated by quenching and tempering. Therefore, the collapsing strength and internal pressure strength of N80Q are higher than that of N80-1. N80-1 or N80Q should be clearly shown by the designer when N80 casing is selected. Asmechanical properties are higher than J55 and K55 types, it may very well be utilized to certain a little more challenging formations. With […]
Pipe with threading&coupling is threaded on both ends and comes with a pipe coupling to connect steel pipes together. The seal provided by a threaded pipe joint depends upon multiple factors: the labyrinth seal created by the threads; a positive seal between the threads created by thread deformation when they are tightened to the proper torque; and sometimes on the presence of a sealing coating, such as thread seal tape or a liquid or paste pipe sealant such as pipe dope. Tapered thread joints typically do not include a gasket. Especially precise threads are known as “dry fit” or “dry seal” and require no sealant for a gas-tight seal. […]
JIS G3461 Grade STB 410 Specification Covers Carbon Steel Tubes for Boiler and Heat Mechanical properties of This steel grades can be varied greatly by heat treating. Through a controlled cycle of heating and cooling, certain desired properties are obtained by producing predictable changes in the microstructure of the steel. It is used for exchanging heat on the inside and outside of the tube, such as water tubes, smoke tubes, superheater tubes and air preheater tubes of the boiler and heat exchanger tubes, condenser tubes and condenser tubes and catalyse.
Cement lining is a process by which steel pipe and fittings are coated internally with cement mortar. This process combines the physical strength of steel with the protective qualities of cement mortar. The lining is applied centrifugally to pipe, creating a smooth finish the length of the pipe. Fittings, flanges, and special spool pieces are lined by hand
ASTM A106 covers carbon steel pipe for high-temperature service. These pipes are suitable for welding, bending, flanging, and similar forming operations. Mechanical testing of the specimens shall include tensile, bending, flattening, hydrostatic and nondestructive electric tests. Specimens undergoing bending tests shall consist of sections cut from a pipe. For flattening tests, the specimens shall be smooth on the ends and burr-free, except when made on crop ends. All tests shall be performed in room temperature. If any test specimen shows flaws it can be discarded and substituted for another test specimen. Before testing, if a specimen has scribe scratches, a […]
16Mo3 and 10CrMo9-10 are EN10216 specified chrome molybdenum steel alloy tubes for pressure Purpose. They are mainly used as boiler water tubes, smoke tubes, superheater tubes, air preheater tubes, etc. It is also utilized to produce pipeline, container, equipment, pipe fittings, and such. Heat Treatment Conditions: Chemical Composition: Mechnical Properties:
3PE, we also called 3LPE.It is used in transferring natural gas, crude oil and refined oil product over long distances. It also can be used in the urban fuel gas piping system, storage tanks, and groove piping system. 3PE’s main purpose is protecting pipes which used in electricity and communication industries and water piping systems. Layers of 3PE coated steel pipe Just as its name implies, 3PE coating including 3 Layers. The first layer of 3PE coating: Fusion bonded epoxy, which thickness is larger than 100μm. ( Thickness of FBE coated ＞100μm ） The second layer of 3PE coating: Adhesive layer. It is binding […]
