The consequences of irregular installation of rubber expansion joints.

With the installation of rubber joints in large quantities, although the products have instructions for use, but there are still many irregularities in the installation of rubber joints, because the use of rubber joints is not standardized to produce a variety of serious consequences, the specific main points are as follows.
Soak deformation: This happens to the ordinary rubber expansion joint installed in the oil pipeline, because the oil rubber has a corrosive effect, a long time of soaking will have a swelling problem on the rubber soft joint, which leads to sealing problems and the decline of their own quality problems, so in the oil pipeline must use oil-resistant rubber expansion joint.

Media leakage: most of the leakage occurs from the installation of irregularities caused by tightening screws is a necessary process to keep an eye on. The method of tightening diagonally cannot be changed, otherwise part of the seal will slacken, leading to leakage of rubber flexible joints.
Dragging situation: The actual stretching of the installed pipeline exceeds the limit stretching length of the rubber expansion joint, which leads to the flange being forced out from both ends of the sphere. It is a great improvement for the vibration of the pipeline.


Dimensional deformation: The dimensional deformation comes from the strong distortion of the pipe. As some pipes are tilted to a greater extent, which leads to distortion during transportation, the rubber expansion joint is a particularly resistant product, but there is nothing you can do about the distortion, so please replace the rubber expansion joint with a high-pressure rubber expansion joint.
