  • The principle of anti-corrosion steel pipes

    The principle of anti-corrosion steel pipes

    Coating anticorrosion is a uniform and dense coating formed on the surface of de-rusting steel pipes, which can isolate it from various corrosive media. Steel pipe anti-corrosion coatings are increasingly using composite materials or composite structures. These materials and structures must have ...

  • Internal and external anti-corrosion measures of steel pipelines

    Internal and external anti-corrosion measures of steel pipelines

    1. The common method of external anticorrosion of steel pipes: using cathodic protection alone is not economical due to too much power consumption. Therefore, the combined protection of the anti-corrosion layer and cathodic protection, the cathodic protection that will be concentrated on the expo...

  • Wall Thickness Accuracy and Straightening Method of Straight Seam Steel Pipes

    Wall Thickness Accuracy and Straightening Method of Straight Seam Steel Pipes

    The control of the wall thickness of the straight seam steel pipe is a difficult point in the production of steel pipes. At present, the methods of straight seam steel pipe manufacturers in the production of wall thickness accuracy generally include: 1. Tube billet heating: the heating should be ...

  • How to detect the corrosion performance of steel flange

    How to detect the corrosion performance of steel flange

    The use of steel flanges in industrial structural parts is mainly to improve the connection and keep the pipelines sealed without leakage. However, many steel flanges will corrode and age after being used for some time, thus losing their tightness. Therefore, it is very necessary to conduct anti-...

  • The difference between thin-walled spiral steel pipe and thick-walled spiral steel pipes

    The difference between thin-walled spiral steel pipe and thick-walled spiral steel pipes

    The concept of thin-walled spiral steel pipe: the strip steel is fed into the welded pipe unit, rolled by multiple rollers, the strip steel is gradually rolled up to form a circular tube billet with an opening gap, and the reduced amount of the extrusion roller is adjusted to make the weld seam g...
