May 12, 2015 · A critical assessment has been made for the electric resistance welded API-J55 and P110 steel pipes to clarify the metallurgical factors crucial to the occurrence of welding defects. Electric resistance welding (ERW) is widely accepted due to its low cost and high efficiency of production as a conventional manufacturing technology for the steel pipes.
We not only can produce 450,000 tons of various sizes of ERW steel pipe, but also can produce deep processing pipe with 100,000 tons. Our annual production capacity of hot dipped galvanized steel pipe is 200,000 tons, capacity of greenhouse engineering material is 250,000 tons and highway column and guardrail is 200,000 tons. Carbon Steel Welded Pipe Low Carbon EFW / ERW Black ERW Black Steel Pipe supplier in India. Altering the content of carbon in steels leads to a change in the properties of the respective alloys. Carbon steels, based on their content could be segregated into three classes - high carbon, medium carbon and low carbon steels.

ASTM 201 304L 316L 321 Stainless Steel Pipe/Tube 304 Stainless Steel Seamless Pipe/Weld Pipe/Tube, 316 310S Stainless Steel Pipe 309S Inox Steel Pipe ERW Steel Pipe and Tube, ERW Welded PipeERW Pipe Manufacturering Process:Straight seam high frequency welded pipe (ERW steel pipe) is formed by forming a hot-rolled coil through a forming machine. The skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the pipe blank. Pressure welding is carried out under the action of a squeeze roller.
ERW steel pipe is a straight seam electric resistance welded pipe, a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. It has sturdy frame which is strong enough to make sure the stable operation. And it is resistant to water, oxygen and corrosion, which is endurable with long life span.

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. Difference in ERW and SAWL Submarine Pipeline and Welding Technology Welded Steel Pipe and ERW/ DSAW Carbon Steel Pipe, Spiral Welding steel tube is one pipe the surface has the steel pipe joint,which is use the steel belt or steel plate material through the bending deformation into round ,square ect then welded into shape.Which can meet customer requirements, the special specifications welded pipe
Welded steel pipe can improve material utilization, simplify manufacturing process, and save steel and processing time. It can be processed into welding, bending and flanging. Welded steel pipe has high precision, uniform wall thickness and high brightness of internal and external surfaces. As the weight of welded pipe is only 1/5 of square Welding Procedures for Steel PipesClass A pipes are generally welded with ordinary carbon steel Q235, Q235F and common low-alloy structural steel 16Mn. Class B pipes are welded with Q235, Q235F, Q195 and other steels, and are used as low-pressure fluid delivery pipes. b. Spiral seam high-frequency welded steel pipe Spiral seam high-frequency welded steel pipe, there is no unified product standard, generally made of ordinary carbon steel Q235, Q235F
