Product Performance

a) Structure: Flanged rubber bellow expansion joint is the soft joint of metal pipes, and consists of inner rubber, nylon cord fabric, outer rubber and metal lap joint flanges.

b) Technology: We introduce advanced technology from abroad, and combine it with Chinese production experience. In the manufacturing operation, the inner side endures high pressure; nylon cord fabrics and the inner rubber are better combined and can work under higher pressure than normal bellow expansion joint.

c) Features: The inner adhesive layer united perfectly, bright, clean and seamless; the tag adopts the vulcanization process, perfectly matches the product. The product can endure high pressure, maintain good elasticity, make large displacement to balance pipe deviation, absorb vibration and make less noise and have easy installation, etc.

2. Application Range

a) Application: Flanged rubber bellow expansion joint can be widely used in the pipe systems for water supply, drainage, circulating water, HVAC, fire protection, paper making, pharmacy, petroleum chemical industry, ship piping system, water pump, compressor and fan etc.

b) Applicable Media: The normal type is used to transport air ranges from - 15 °C to 115 °C, compressed air, water, sea water, oil, acid and alkali etc. The special type is used to  transport the media above ranges from - 30 °C to 250 °C, oil or strong alkali, strong acid and solid material.

This is the picture of the rubber bellow expansion joint produced by our company, we are able to produce various sizes of bellow expansion joint as your demand.
