Introduction And Difference Between Seamless and Welded Pipes. Seamless Steel Pipe is made from a solid round steel billet which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Seamless pipes are manufactured in a variety of size and schedule. Difference Between Seamless and Welded/ERW PipesIntroduction And Difference Between Seamless and Welded Pipes. Seamless Steel Pipe is made from a solid round steel billet which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Seamless pipes are manufactured in a variety of size and schedule.
Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections. ERW Steel Pipe-ERW Steel PipeSSG High-frequency longitudinally welded pipe production line is mainly used for the production of welded steel pipe of 8 ~ 610 mm and wall thickness of 0.5~ 20mm as well as the production of square, rectangular, and other custom seamless pipe profile, Carbon steel pipe, ERW steel Tube. ERW steel pipe and tubes, ERW Steel Pipes Manufacturers,ERW (Electric Resistance Welded) round steel tube and pipe is available in a large selection of diameters and wall thickness.

Electric Resistance Welded or ERW refers to a type of welding process that is used to make square tubing. It is specifically known as Seam welding. Steel strips are unwound from coils and side-trimmed to control width and condition the edges for welding.

Difference in ERW and SAWL Submarine Pipeline and Welding TechnologyThe Pipe Making Principle of ERW High Frequency Welded Dec 15, 2020 · ERW straight seam steel pipe is made by using the skin effect of high-frequency current to quickly heat the edge of the formed tube to the welding temperature and then perform extrusion welding. According to different power feeding methods, ERW welded pipe can be divided into high frequency contact welding and high frequency induction welding.
