oil transportation q235b coil material
Q235B spiral pipe is a commonly used raw material in spiral pipes.It is a spiral seam steel pipe welded with strip steel coil as the raw material and active double wire double-sided submerged arc welding.
Q235B steel pipe production process:raw materials is a strip coil, the temperature often extruded to automatically double wire double submerged arc welded steel pipe technology. That raw steel coil, wire, flux. Go through rigorous physical and chemical testing before it is put. Strip head and tail docking, a single wire or twin-wire submerged cheap q235b oil transportation material - Hot Rolled Steel cheap q235b oil transportation material.
