DN15-DN80 Threaded Expansion Joint 200mm-270mm Length Adjustable Lightweight

Hot sale agent discount BSPT NPT threaded rubber expansion joint

Rubber joint is a kind of hollow rubber product used for flexible connection between metal pipes
Rubber soft joint products are widely used in water, electricity, chemical industry and ship mooring systems, with high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light quality, vibration reduction, easy installation, flexible use and easy dismantling and repair, as well as acid, alkali resistance and oil resistance.

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.
