pipes

(Seamless & ERW)

Steel pipes are cylindrical tubes made from steel that are used many ways in manufacturing and infrastructure. They’re the most utilized product made by the steel industry. The primary use of pipe is in the transport of liquid or gas underground—including oil, gas, and water.

Seamless Pipes: Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes.

ERW pipes : ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape. In the initial times it was done with the low frequency A.C. current to heat the edges.
