Detailed descriptions of Rubber Expansion Joints
This product is used as soft joint for metal pipeline. It is composed with rubber globe and metal free flange. The rubber globe is compounded by inner rubber layer, cotton twill fabrics strengthen, outer rubber.
1. |
Compact , light weight , and easy installation . |
2. |
Structural noise transmission can be reduced with the restrict and flange non-parallelism |
3. |
Reasonable structure and high flexibility long service life |
4. |
Consist of fabric reinforced and metal flange loose joint. |
5. |
The inner seamless high-pressure rubber joint is developed by us which prevents corrosive medium from etching the inner wall of the rubber joint in high temperature, acid, alkali and oil resistance pipeline, thereby it also can extend its service life span. |
6. |
Widely used in the field of chemical industry, construction, supply water, sewage drainage, petroleum, light and heavy industry, sanitation, plumbing, electricity and other fundamental engineering. |
7. |
Received considerable acceptance all over the world |
