detailed description of rubber joints threaded:

Flexible rubber joint is also called shock absorber,pipe shock absorber,shock proof box and soft joint ,and so on. It is a pipe joint of high-flexibility,high-gas tightness,resistance to medium and climate.

It has such functions as following:

1.Small volume,small weight,good flexibility,easy installation and maitenance.

2.It can make horizontal,axial and angular displacement when being installed.It cannot be restricted by the obstruction of pipe and the non-parallel of flange.

3.It can reduce noise passed through structure when it works and has strong shock absorption.

4.Our company personally develops inner non-seal high-pressure rubber joint that can prevent effectively inner wall of rubber joint from the corrosion in the pipe of high-temperature resistance,acid and alkali resistance and oil resistance to improve the use life.

Applicable to:

Due to its good integral function,flexible rubber joint is used widely in key projects of chemical industry,construction,water supply,drainage,petroleum,light and heavy industry,refrigeration,health,fireproof and power,etc.
