Abter is specialized in the production of Welded Steel Pipeline & Tubes. Welded Steel Pipeline (WSP) includes a steel cylinder lined with cement mortar and coated with a dense cement mortar. An easily assembled leak-proof joint is supplied by using bell and spigot steel joint rings bonded to the ends of the cylinder and sealed with a restricted round rubber gasket. Larger sizes, other lengths and styles for higher operating pressures and a wide array of finishings and joint setups are also readily available. We produces it with the client’s requirements also.
ERW pipes means Electric Resistance Welded Pipeline. API 5L ERW pipes are used in various engineering functions, fencing, scaffolding, line pipes and so on. ERW pipes are offered in various qualities, wall thicknesses, and sizes of the finished pipelines.
The most crucial feature of erw steel pipeline is no foreign filler metal, heating speed, high production efficiency, which is an advantage, but likewise its shortcomings, which is no filler metal, the filler alloy will not benefit technique to improve the weld homes element; heating temperature is high, the sound is short, the welding temperature gradient is greater, so that some of the steel is susceptible to hardening stage and organize tension make the weld fragility, extensive mechanical performance in the welding process. For that reason, the ERW pipe weld joint need to be performed after the remedial procedures – weld heat treatment to improve the company, remove stress and improve efficiency.
what is the difference of ERW pipe and seamless pipe?
Electric Resistance Welding (ERW) pipe is produced by rolling metal and after that welding it longitudinally throughout its length. Smooth pipeline is made by extruding the metal to the desired length; therefore ERW pipeline have actually a bonded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out
In Seamless pipe, there are no welding or joints and is manufactured from strong round billets. The smooth pipeline is finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD. Relevant in for High-pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Expedition & Drilling, Oil & Gas Transport and Air and Hydraulic cylinders, Bearings, Boilers, Autos and so on
ERW’s advantages over seamless pipes:
Low expense: the low raw material expense and manufacturing expense makes its rates more competitive than longitudinal joint submerged arc welded pipes and seamless pipelines
High weld joint security: as an outcome of unique welding technique of melting the moms and dad metal together, without filler metal, the weld property is much better than submerged arc welded pipelines, the seam security is considerably improved.
