  • Heating defect of seamless tube billet

    Heating defect of seamless tube billet

    The production of hot-rolled seamless tube generally requires two heatings from the billet to the finished steel pipe, that is, the heating of the billet before piercing and the reheating of the blank pipe after rolling before sizing. When producing cold-rolled steel tubes, it is necessary to use...

  • 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...
