The features of our rubber expansion joint
1.Small volume, light weight, good elasticity, easy installation and maintenance.
2.Installation can generate horizontal, axial and angular displacement, from pipe barrier heart, flange is not parallel to the limit.
3.Work to reduce structural transmission of noise, vibration absorption ability.
4. Good sealing performance and scalability, easy to use. Internal high density, can endure high pressure, elastic deformation effect is good.
5.Use of rubber of high elasticity, high resistance, solvent resistance, weather resistance and radiation resistance and other advantages can reduce vibration and noise, and play the role of compensation for thermal expansion and contraction caused by temperature chang
The application of our 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.
Installation Instruction of Rubber expansion joint
I. Installation over displacement limit is not allowed when installing the flexible compound rubber joint .
II. For ground-horizontally ,suspense and vertically installed rubber joints with over 1.0Mpa pressure,both sides of the pipeline shall have
support or support bracket,to avoid fall or damage.
III.The force of fixing support or bracket shall be greater than the axial force of working.Otherwise the anti-fall devise is required .
IV. It shall install the GB/T9115.1(RF) standard flange(small diameter flange) when installing the corresponding flange of flexible compound rubber joints.The size of flange D2 and do shall not be too small for preventing the leakage of sealing face.
V. It shall screw down symmetrically and gradually when installing the flange screw of flexible compound rubber joint,To avoid the partly leakage or damaging the sealing face of the rubber joint.
VI. When the rubber joint is installed vertically or in suspense with over 1.0Mpa pressure ,the screw shall be installed with gasket for preventing partly leakage due to loosened screw.
VII.The flexible compound rubber joint shall have fixing support when vertical installation is made .Heavy press on the rubber joint is forbidden .

Our products are subject to stringent checks, so you can rest assured that the quality of products .And our products have gotten high praise from clients domestic and overseas.
Rubber expansion joint is assembled with rubber hose and retaining
ring flanges,and the rubber hose could be damaged in delivery. So Huayuan packs each flexible rubber joint with a separate carton case to prevent the crash of the flanges and rubber hoses, each case painted the name of rubber joint and other details. The carton cases then be filled to plywood cases to ship. Inside of each plywood case, Huayuan always uses moistureproof material to keep the products
