Clamp Type Rubber Expansion Joint
Description
clamp type rubber joint use clamp instead of flange and bolt, install the pipe orifice on both sides of rubber joint to the connecting pipeline, then use clamp to fix connection between rubber joint and pipelines; just loosen the clamp when dismounting. In this way to compensate pipeline displacement which is caused by thermal expansion and water delivery.

Advantages
Another benefit of using a clamp type rubber expansion joint is its durability; it can last up to 10 years with minimal maintenance required during that time period. Furthermore, since no welding is required when installing these joints, installation costs tend to be lower than other types of fittings available on the market today. Finally, these joints are resistant to corrosion which makes them suitable for use in harsh environments where other materials may not stand up well against extreme conditions like saltwater exposure or intense heat/cold temperatures fluctuations.
Application
As rubber has superior capability in resistance of acid, alkali, oil and electrolyte, rubber joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical, Petrochemical, Marine, Power Generation, Pulp and Paper, Steel Mills, Water and Wastewater Treatment, Building Construction, Heavy Industry, Freezing and Sanitary Plumbing.
