Product Description

DN100 rubber expansion bellows joint

The rubber expansion bellows are made of high-strength, cold and hot stable polyester cord, which is cross-linked by high-pressure and high-temperature molding. The internal density of the rubber expansion bellows are high, and it can withstand high pressure. The elastic deformation effect of the rubber expansion bellows are excellent. The product structure is designed with high end arc and long curve, and the rubber expansion bellows have a large number of displacement functions.


Performance characteristics of rubber expansion bellows


1. The rubber expansion bellows has the advantages of small size, light weight, good ductility and convenient installation and maintenance.

2. Rubber expansion bellows installation can cause horizontal, radial, angular offset, will not be limited by the pipe plug center, flange uneven surface.

3. When the rubber expansion bellows is working, it can reduce the structure transmission noise and has strong vibration absorption ability.

Note: 1. The special requirements of rubber expansion bellows can be customized according to user's drawing. 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 ball of rubber expansion bellows can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the rubber expansion bellows above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the rubber expansion bellows shall be installed with anti falling device.
