Product Description
Best quality EPDM flexible rubber expansion joint
Rubber Expansion Joints are designed for piping systems to absorb pipe movements, relieve stress,
reduce system noise/vibration, compensate for misalignment/offset and to
protect rotating mechanical equipment against start up surge forces.Because of rubber has superior capability in resistance of acid, alkali, oil, and electrolytic, Rubber Expansion
Joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical/Petrochemical, Marine, Power Generation,
Pulp/Paper, Steel Mills and Water/Wastewater Treatment.

Features of flexible rubber expansion joint
1.Small volume,light flexible ,easy to install and maintain
2.It reduces structural noise transmission with strong shock absorption in servive.
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 .
Installation Instruction of Flexible Rubber 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 .

NOTE:
1. Flexible Rubber joints supply range can be up to DN3000, detailed data can be offered upon request.
2. Control units must be used when piping is not properly anchored.
3. The rated pressure 2.5MPa products will only be sold with control units
4. Flexible Rubber joints pressure rating is based on 30°C operating temperature. The pressure rating is reduced at higher temperatures
5. Flexible Rubber joints weights in the above table are joints with DIN PN16 drilling retaining ring flanges.
6. Movements shown in the above table are non-concurrent.
7. Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times " work pressure".
8. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon
Rubber expansion joints Flexible rubber joint is assembled with rubber hose and retaining ring flanges, and the rubber hose could be easiely
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.
