Welded steel pipe refers to steel belt or steel plate bending deformation into a round, square and other shapes after welding, surface joints of the steel pipe. The welded steel pipe has lower cost and higher production efficiency than the seamless steel pipe, and the blank used is steel plate or strip steel. Welded steel pipe has strong corrosion resistance in acidic environment. Welded (ERW, LSAW, SSAW) steel line pipe: 1/2�?�¢?? to 60�?�¢?? Range of Thickness: SCH 10 to SCH 160 Ends Type: Beveled ends, Plain ends Range of length: 20FT, 40FT or customized Protection Caps in plastic or iron available Surface appearances: Natural, Varnished, Black painting, 3PE, FBE, etc

There are 3 welding types: ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. Welded (ERW, LSAW, SSAW) steel line pipe: 1/2â?? to 60â??

Welded pipes is steel plate or steel belt, and the surface is a pipe with welding ribs after cutting, bending, welding and other processes. The main advantages of welded pipes are their lower inherent cost, narrower tolerances for wall thickness, concentricity (OD/ID) and internal surfaces that can be checked prior to manufacture. Welded steel pipe is divided into furnace welding pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding forms into straight seam welding pipe and spiral welding pipe two kinds, because of its end shape is divided into round welding pipe and special-shaped (square, flat, etc.) welding pipe. Seamed pipes offer tighter tolerances but thinner wall thickness rather than seamless pipes. Welding pipe can be used for water pipeline, gas pipeline, heating pipeline, electrical pipe and so on.
