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:
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.
