Angle Pad Grooved Piping System Pipe Coupling
An angle pad coupling is a new pipe connector that uses pressure and a self-tightening sealing ring force produced by medium pressure for a seal. This coupling features a small volume, light weight, and simple structure. Each coupling has only two bolts, which are easy to install and maintain. The installation can be selected at random when for easy operation. This angle pad coupling is especially useful in fire-fighting, gasoline, and water supply, as it is a more convenient and economical solution than traditional welding connections.
Constitute and Working Life
The housing, nuts and bolts can all be used for 50 years, and the sealing ring can be used for 15 years.
