    The difference between fixed welding joints, rotating welding joints, and prefabricated welding joints in steel pipeline welding

    Fixed welding means that the joints of the steel pipes cannot be moved after being assembled, and the welding is performed according to the change of the welding position (horizontal, vertical, upward, and mid-level changes) during the welding process. Rotating the welding port is to rotate the w...

    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

    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...
