Comparison Between ERW and Seamless Steel PipeERW steel pipe:Hot-rolled strip steel is used as the raw material. The thickness tolerance of modern hot-rolled strip steel can be controlled within 0.05mm, and seamless steel pipe is produced by round steel perforation, and the wall thickness deviation is large. Subsequent

LSAW Steel Pipe VS. SSAW Steel Pipe

LSAW and SSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally. In the SSAW type, steel coils are welded spirally, like a helix, so that the coil (strip) assumes the shape of a pipe. PPGI coil in Australia - Goldensun SteelTianjin Goldensun Import& Export Co., Ltd.

Spiral Welded Pipe Manufacturers in India, Best Prices for

Oct 23, 2018 · Helical submerged arc welded pipes or commonly referred as spiral welded pipes are made from hot rolled coils. In a spiral saw pipe, hot rolled coils from the de-coiler are formed into a spiral loop. This spiral loop is then welded from inside and outside of the pipe. The pipe then rolls onto the bench for visual inspection. Welded Pipes (ERW, LSAW, SSAW) Danyal PipelinesSSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. What is a SSAW pipe? - pipelinedubaiApr 14, 2019 · SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.
