Overview
Clamp flexible rubber joint is composed of inner layer, polyamide fiber cord fabric, outer layer rubber and lapped joint flange, it have many advantage such as high temperature and pressure resistance, high-flexibility reduce structural noise strong shock absorption and easy installation, extensively used in the water supply, drainage cyclic water air conditioning paper making petroleum chemical industry, pump and duct fan pipeline system.
The expansion joint pipe manufacture is manufactured through welding or metal casting, and the loosing part is sealed by echelon ring rubber. Operated by gland and bolt and based on the principle of rubber’s elastic deformation under pressure, the seal ring will be deformed and static seal will be done between joint body and expansion pipe wall.
Features
1.Clamp Flexible Rubber Joint can greatly reduce pipeline system vibration and noise, can solve the problem of joint displacement axial expansion, etc.
2.According to different materials, flexible rubber joint can be made into many kinds: acid resistance, alkali resistance, corrosive
resistance, oil resistance, heat resistance, adapt to many mediums and different environment.
3.Material is polar rubber, good sealing, light weight, easy installation, long service life, avoid contacting with sharp metal device.
4.If use overhead, can match with elastic support, when installation, bolt with diagonal method to tighten up.
5. If pipeline pressure is high, use bolt connect the flange both ends.
