Union EPDM Thread Connected Pipe Coupling Sphere Rubber Expansion Joints Compensator
The form: this product consists of rubber pipe ,made of inner glue ,multi-layer proofinf and cord fabric and outer glue abd metal woggle joint .It is applicable for the connection of inlet and outlet pipes of various fancoil sets of air conditionings in the guest rooms of hotels and restaurants.
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.
