Ductile Iron Rubber Expansion Joint

Expansion bellows for pipes

 

The double ball rubber expansion joint is composed of rubber body and flange. The rubber material of the expansion joint is NR / NBR / EPDM / PTFE, which can be used for different media, such as EPDM with weak acid and weak alkali. Flange materials can be galvanized carbon steel, painted ductile iron, stainless steel 304 / 316, etc.

 

Expansion bellows for pipes performance

 

Using the advantages of high elasticity, high gaseous state, medium resistance, weather resistance and radiation resistance of rubber, the expansion joint can reduce the vibration and noise of pipeline and compensate the thermal expansion and cold contraction caused by temperature change.

1. Reduce vibration and noise of pipeline system; Completely solve various pipeline problems, such as pipeline displacement, axial bending, etc.

2. According to different material requirements, acid, alkali and corrosion resistant expansion joints can be made to adapt to different media and environments.

3. Good sealing performance, light weight, convenient installation and maintenance and long service life. However, please keep away from sharp metal to prevent the steel ball from breaking.

Note: the special requirements of double ball rubber expansion joint can be customized according to the user's drawings. The flange standard is GB / t9115. 1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber balls of expansion joints can be used as natural rubber, EPDM, neoprene, butyl rubber, butadiene rubber, fluororubber, etc. When the double ball rubber expansion joint of DN200 and above is used for suspended water supply, the pipeline must have fixed support or fixed support, otherwise, the double ball rubber expansion joint shall be equipped with anti falling device.
