Product Description
GREAT WALL Stainless Steel Straub Coupling with Copper Anchoring Teeth is high performance coupling suitable for varied pipe systems.
Our Coupling provide Axial Restraint for Pipe Connection .
Our straub couplings used to join Metal Pipe to Metal Pipe or Metal Pipe to Plastic Pipe or Plastic Pipe to Plastic Pipe .
They are mainly used for building construction or civil engineering, power plants and etc .
This pipe joining coupling absorbs unexpected field stress and applies perfect for seismic retrofits
All of our Coupling designated with GRIP have axial restraint .
In order to able to absorb the axial forces arising from the internal pressure,
anchoring teeth engage in the relevant pipe materials and provide a mechanical frictional connection.
If the axial tensile load on the pipe increases due to increasing internal pressure,
the teeth engage deeper inot the pipe surface .
These flexible and lightweight Couplings come fully assembled and can be installed without using any special tools .
1. Briefs :
* Mainly used for varied pipe connection
* Specific designed for plastic pipe such as PE, PVC, PPR, HDPE pipe
* Suit for water, gas, industry pipeline
2. Features :
* used for connection of two plastic pipe or the connection between plastic pipe and metalic pipe
* also used for the leaking pipe repair
* allow angular deflection and provide restraint
* anticorrosive
* easy installation and disassembly
