Expansion Joint with Flanged Type

Pipe in use process, will inevitably encounter heat bilges cold shrink, the heat-expansion and cold-contraction when not so obvious as rubber products, but when the pipes are in a state of heat or cools down, suddenly pipeline might suddenly long or short, this kind of situation is harmful for pipe, rubber expansion joint, used to prevent pipeline is damaged due to the heat bilges cold shrink. Rubber expansion joint is to protect the thermal expansion and contraction of the pipeline and especially exist. Each rubber expansion joint can be extended or shortened. When the pipeline is heated and expanded, the rubber expansion joint will be shortened.

1. it is strictly prohibited to install over the displacement limit.
2. The mounting bolts should be symmetrical and gradually tightened to prevent partial leakage.
3. Working pressure above 1.6.MPa, the mounting bolts should have elastic pressure pads to prevent the bolts from loosening during operation.
4. When installing vertically, the joint pipe should have vertical force support at both ends, and the anti-pull device can be adopted to prevent the work from being pulled off.
5. The rubber joint installation site should be away from the heat source. Ozone area. It is strictly forbidden to expose the radiation and use media that does not meet the requirements of this product.
