Product Overview

Description


 


Product Description


Bellows rubber joint is a type of pipeline joint with high elasticity, high air tightness, moderate resistance, and weather resistance. It is a composite rubber pipe composed of an inner rubber layer, a fabric reinforcement layer, an intermediate rubber layer, an outer rubber layer, and a metal or steel ring reinforced at the end. After high-temperature and high-pressure vulcanization, it is loosely bonded with a metal flange or parallel joint. 





Functions


1. Small size, light weight, good elasticity, and convenient installation and maintenance.


2. Absorb lateral, axial, and angular displacement caused by pipeline vibration, without being limited by non concentric pipelines and non parallel flanges.


3. Reduce the noise generated by pipeline water pump vibration and have strong vibration absorption ability.


4. High temperature resistance, acid and alkali resistance, oil resistance, and improved service life.

Note: 1. Special requirements can be customized according to the user's drawings. The flange standard is GB / t9115.1-2000. A variety of flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. Rubber spheres can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene green rubber, fluororubber, etc.2. When the suspended water supply uses products above DN200, the pipeline must have fixed support or fixed bracket, otherwise the product should be installed with anti pull off device.
