Spiral steel pipe enterprises
For the production of seamless steel pipe enterprises, spiral steel pipe must not be strange.Spiral steel pipe is mainly made of strip steel coil as raw material, which is formed by warm extrusion and welded by automatic double-sided submerged arc welding process.The manufacturing technology is also improved on the basis of straight joint steel pipe.When making, need to install strict craft standard.
The first step is to identify the raw materials.The raw materials are strip coil, wire and flux.All raw materials are subject to strict physical and chemical inspection before input.
