The complete name of SAW steel pipe is
Submerged Arc Welding Steel Pipe, and it is maded out with submerged arc welding process technology. Electric current density is quite high and flux layer help to prevent rapidly dissipating heating, moreover will make heating focused on the welding area. The advantage of SAW pipe is high quality, efficient production rate, no arc light and few dust. It is widely used in pressure vessel, pipe fittings manufacture, beams, low pressure fluid, steel structure engineering
