    What three processes are included in the heat treatment of carbon steel tubes?

    According to different conditions, the metal material is heated to a suitable temperature and kept warm, and then cooled in different ways to change the metallographic structure of the metal material and obtain the required structural properties. This process is usually called metal material heat...

  • Welding method of spiral steel pipe

    Welding method of spiral steel pipe

    Spiral pipe is a spiral seam welded pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. The welding method of submerged arc automatic welding is the same as manual welding in that it still ...

  • Reasons for the rust of spiral welded pipe

    Reasons for the rust of spiral welded pipe

    Spiral welded pipes (ssaw) are stacked outdoors, and most of them are buried underground when in use, so they are easy to corrode and rust. In order to ensure the smooth flow of the pipeline, the spiral welded pipe must have strong corrosion resistance. Once the pipeline is corroded, it will caus...
