    Spiral steel pipes protect the important materials in media transportation. Spiral steel pipes are the outer wall anti-corrosion of steel oil, gas, water, and heating pipelines. To what extent can the durability of spiral steel pipes be improved? The durability of spiral steel pipes has become an important signal for urban development! ​ Surface treatment of spiral steel pipe is conducive to i...

  • How to deal with sealing methods of flange leakage

    Date:2023-12-26      View(s):281      Tag:flange, sealing flange, flange leakage

    First, the leakage location and condition. The flange bolts connecting both sides of the DN150 valve body are leaking. Since the flange connection gap is extremely small, it is impossible to inject sealant through the gap to eliminate the leakage. The leakage medium is steam, the leakage system temperature is 400~500℃, and the system pressure is 4MPA. Second, the sealing construction method is ...

  • The production process of spiral welded steel pipe

    Date:2023-12-22      View(s):285      Tag:spiral welded steel pipe, welded steel pipe, spiral steel pipe

    Spiral welded steel pipe is also a type of welded pipe equipment. Its strength is generally higher than that of straight seam welded steel pipe. It can use narrower billets to produce welded steel pipes with larger diameters. It can also use billets of the same width to produce welded steel pipes with different diameters. Steel Pipe. However, compared with straight seam steel pipes of the same len...

  • The principle of anti-corrosion steel pipe

    Date:2023-12-19      View(s):323      Tag:anti corrosion steel pipe, industrial steel pipe, principle anti corrosion steel pipe

    Coating anti-corrosion is a uniform and dense coating formed on the surface of rust-removed metal pipes. The coating can isolate it from various corrosive media. Steel pipe anti-corrosion coatings increasingly use composite materials or composite structures. These materials and structures must have good dielectric properties, physical properties, stable chemical properties, and a wide temperature ...
