ERW Pipe. All Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes. There are many Differences between Seamless & ERW Pipe. The main Difference is that the Seamless Piping is suppliers by hot-working steel or, if necessary, by subsequently cold-finishing the hot-worked product to produce the desired shape, dimensions, and

NomenclatureConstructionAdvantagesOperationsProductsDifference between Seamless & ERW Stainless Steel pipeNov 24, 2014 · ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24 OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.

Electric Resistance Welded - an overview ScienceDirect For steel tubes, the ERW tube has better formability and lower cost compared with DOM tubes and seamless tubes. Laser-welded tubes, having high manufacturing costs, are mainly used for complex-shaped parts with large deformation due to having the best shaping property. Fine-grained and smooth flow lines can be found in seamless tubes.

The difference between SureThread CW Pipe & Import ERW Nov 06, 2015 · Where import ERW pipe is cold-formed, SureThread is hot-formed. Throughout the process of CW pipe formation, the entire steel pipe is heated, not just the edges as in ERW pipe. During a process called annealing, the manufacturers heat and slowly cool the steel to reduce its brittleness.
