  • Reasons for bending of steel pipes

    Reasons for bending of steel pipes

    1. Uneven heating of steel pipe causes bending The steel pipe is heated unevenly, the temperature along the axial direction of the pipe is different, the structure transformation time is different during quenching, and the volume change time of the steel pipe is different, resulting in bending. 2...

    Methods for forming and processing large-diameter steel pipes

    Large-diameter steel pipes are also called large-diameter galvanized steel pipes, which refer to welded steel pipes with hot-dip plating or electro-galvanized layers on the surface of large-diameter steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and extend their ser...

  • How to deal with different wall thicknesses of boiler steel pipes

    How to deal with different wall thicknesses of boiler steel pipes

    When the thickness of the boiler steel pipe wall is different, compensation gaskets can be used to deal with it. 1. The thickness of the steel pipe wall can be thickened or thinned to achieve the required thickness. 2. When the steel pipe wall thickness is inconsistent, high-strength bolts and wa...

  • What are the differences between the surface processing of spiral steel pipes and stainless steel pipes

    What are the differences between the surface processing of spiral steel pipes and stainless steel pipes

    Original surface of stainless steel pipe: NO.1 The surface that is heat treated and pickled after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., with thicker thicknesses ranging from 2.0MM-8.0MM. Blunt surface: NO.2D After cold rolling,...

  • The difference between submerged arc welded spiral steel pipe and straight seam high frequency welded steel pipe

    The difference between submerged arc welded spiral steel pipe and straight seam high frequency welded steel pipe

    Submerged arc welding spiral steel pipe uses continuous welding wire as the electrode and filler metal. During operation, the welding area is covered with a layer of granular flux. The large-diameter spiral tube arc burns under the flux layer, melting the end of the welding wire and part of the b...
