    Description


    Welded Pipe tube
    Straight seam welded pipes, steel pipes made by coil welding of hot-rolled or cold-rolled steel plates or steel strips, and pipes obtained by straight seam welding on welding equipment are called straight seam welded pipes.
    Among them, according to different uses and different post-production processes, (they can be roughly divided into scaffolding tubes, fluid tubes, wire casings, bracket tubes, guardrail tubes, etc.). Low-pressure fluid welded pipe is a type of straight seam welded pipe. It is generally used for water and gas transportation. After welding, it undergoes one more hydraulic pressure test than ordinary welded pipes.
    Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warm extruded and welded by automatic double wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel to the welding pipe unit, and the strip steel is rolled by multiple rolls. The strip steel is gradually rolled up to form a circular tube blank with an open gap. Adjust the reduction of the extrusion roll to control the weld gap at 1~3mm, and make both ends of the weld crater flush.
