Product Description

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
