Why Does The Stainless Steel Pipe Elbow Leak In The Pipeline

Stainless Steel Weld Elbow all have their own advantages and uses. Elbows are a common type of connecting pipe fittings used in pipeline installation and are used to connect pipe bends. Stainless steel stamped elbows are used to connect pipe bends. Connect two pipes of the same nominal diameter to make the pipeline turn at an angle. Stainless steel stamped elbows, cast steel elbows, alloy steel elbows, stainless steel stamped elbows, copper elbows, aluminum alloy elbows, etc. are divided by material.

What are the reasons for the leakage of stainless steel pipe fittings elbows in the pipeline?

1. Misalignment: Misalignment refers to the situation where the pipeline and the flange are in a vertical state, but the two flanges are not concentric, so that the surrounding bolts cannot enter the bolt hole freely. Some will use expansion or use small bolts, but this will reduce the tension of the flange.

2. Deviation: Deviation means that the pipeline and the flange are not in a vertical state, and the flange surface is not parallel and concentric. If the internal medium pressure exceeds the load pressure of the gasket, leakage will occur.

3. Staggered holes: Staggered holes are relatively easy to understand. That is, the pipe and the flange are concentric, but the distance between the bolt holes of the two flanges is too large, and the bolts will generate stress. After a long time, the bolts will be cut off, resulting in sealing failure.

4. Corrosion: The long-term corrosion of the corrosive medium on the gasket will cause chemical changes in the gasket, making the gasket soft and losing its compression force.
