Threaded Coupling Union Type Expansion Joint EPDM Rubber Expansion Joint
The soft joint of thread-fastened rubber takes advantage of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of rubber. The material of thread-fastened rubber joint is forged/cast (round or square) by curing high-pressure and high-temperature dies after oblique crossing and compounding of high-strength and heat-resistant polyester cord cloth.
According to different media, rubber materials are also different, including natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber,Ethylene Propylene Diene Monomer, neoprene rubber, silicone rubber, fluorine rubber and so on. It has the characteristics of heat-resistant, acid resistant, alkali resistant, corrosion resistant, wear-resistant, oil resistant and so on.
according to the work pressure:
Six grades of 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa and 6.4MPa.
Threaded union rubber expansion joint Advantage:
A: 15 minutes zinc plating, high pressure resistance, high temperature resistance, oil resistance, wear resistance, corrosion resistance, acid and alkali resistance.
B: Connect with pump, valve, fire fighting equipment, pipe which vibrate big, pipe which hot and cold change frequently.
C: Natural rubber content of forty-seven percent, can continue to use for 15 years without aging.
EM Thread-Connection expansion joint for high vibration absorbing ability can be customized DN15-DN80.
EPDM Thread-Connection expansion joint for high vibration absorbing ability after surface and treatment and inspection of finished products.
EPDM Thread-Connection expansion joint for high vibration absorbing ability
1. All expansion joints are finshed with retaining flanges,limit rod units are available on special request.
2. Pressures shows are recommended“operating”,test pressure is 1.5time“operating”,burst pressure is 3 time “operating”.
3. Vacuum rating is based on neutral installed length without external load.Products shall not be installed “elongated”on vacuum applications.
4. Do not weld near the expansion joints or weld the steel flanges to the piping after the expansion joints are installed .This will either burn or seriously damage the expansion joints.
