    Welded steel pipe is formed by rolling plate and welding the seam. It is cost-effective pipe with tighter Dimensional tolerances and less weight. It is intended for conveying gas, vapor, water or other liquid in low and medium pressure ambient, such as water mains system, sewerage system, Oil differentce between ERW pipe and EFW pipeElectric Flash Welded Pipeline Electric flash welded pipe was manufactured starting in 1927. Flash welding was achieved by forming a steel sheet into a cylindrical shape. The edges were heated up until semi-molten, then required together till molten steel was dislodged of the joint and formed a bead.Difference between Seamless & ERW Stainless Steel pipePearlites steel is one of the leading ERW Stainless Steel Pipes Manufacturer and exporter from India.

    Welded vs. seamless steel pipe | American Piping Products

    Welded pipe starts out as a long, coiled ribbon of steel called a skelp. The skelp is cut to the desired length, resulting in a flat rectangular sheet. The width of that sheets shorter ends will become the pipes outside circumference, a value that can be used to calculate its eventual outside diameter.
