ERW pipe means electric resistance welded pipe, and it is a resistance welding by 10-500 kHz of high-frequency current. The raw material of the ERW steel pipe is hot rolled steel coil made of steel billet, and the usual material is Q195, Q215, Q235, Q355 in China ERW pipe grade, which are same material with S195, S235, S355 in Europe, and SS400 in Japan. ERW Steel Pipes:Spiral submerged-arc welding pipesDouble Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. SAW pipes. SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available. 3PE steel pipe. ERW Steel pipeERW steel pipe is one of the main pipe structural material in construction and liquid transfer steel material. It is properly used in bridge building, underground transfer assemble structure ,agriculture, chemical liquid transfer, oil and gas transfer and so on, It will be manufactured by electricity resistance welding.
