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 ...

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...

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 ...
