Rubber joints are applied to different pipelines, there have been nearly 30 kinds. The most common ones are wear-resistant, acid-resistant, high temperature-resistant, oil-resistant, etc. , and then its elasticity peoperty can offset to point that change cause by pipelines expand and contract by themselves. The main function is to make use of the elasticity of the rubber itself to compensate for the changes caused by the expansion and contraction of the pipeline.
The high temperature resistant rubber joint is made of EPDM rubber joint, a kind of terpolymer, has high properties of heat resistance, acid and Alkali resistance, ozone resistance and so on. The temperature of ordinary rubber joint is below 80 °C, the EPDM rubber can be used below 120 degrees for a long time, but also can withstand the general weak acid and weak base environment, thus greatly improving the scope of application of products.
