Dn200 Pn10 Epdm Flange Type Rubber Bellows Expansion Joint:

Product Description

I.Structure of Rubber Expansion Joint:

Rubber expansion joint , also called the soft rubber joints, flexible rubber joints, rubber flexible joints, high-pressure rubber joints, rubber shock absorbers, compensator and so on.

Rubber joints generally from the inside layer, fabric reinforcement layer (scraping gum enhanced multi-layer nylon cord), in the layer, the outer layer, the ends of the reinforcement metal ring or bead, high temperature, high pressure molding after curing, and parallel connector loose metal flange or a combination of complex sets of rubber hose. This product utilizes the high elasticity of rubber, high gas resistance, chemical resistance, weather resistance and radiation resistance, etc., can reduce the vibration and noise pipeline, and thermal expansion and contraction due to temperature changes from the compensation due to.

According to the different media used in different rubber material,Incould NR,NBR,Neoprene,EPDM.

II. Feature of Rubber Expansion Joint:

1.Small volume, light flexible ,easy to install and maintain

2.It reduces structural noise transmission with strong shock absorption in service.

3.It is capable of horizontal, axial and angular displacement with the restruction and flange non-parallelism.

4.The inner seamless high-pressure rubber joint independently developed by us prevents corrosive medium from etching the inner wall of the rubber joint in high temperature ,acid and alkali and oil resistant pipeline, thereby extending its service life .

III. Application of Rubber Expansion Joint:

Because the rubber joint has good comprehensive properties, so it is widely used in chemical industry, construction, water supply, drainage, circulating water,

oil, light and heavy industry, frozen, sanitary, plumbing, electricity and other infrastructure projects.fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding,

water pump, compressor, fan and other piping systems.

IV.Installation instructions of Rubber Expansion Joint:

rubber joint pipeline construction, must let it in a state of nature, not the human when installing the product produce human deformation when pipeline medium for acid and alkali resistant oil temperature and other special material should choose higher than pipe work pressure a gear of the joint
