Restraint Stainless Steel Straub Pipe Coupling with Gear Ring
1. Product Introduction :
Our Stainless Steel Grip Straub Coupling is similar to STRAUB-METAL-GRIP which is a high performance coupling suitable for all pipe systems.
This Coupling is mainly used for building construction or civil engineering, power plants and etc .
This pipe joining coupling also absorbs unexpected field stress and applies perfect for seismic retrofits
Stainless Steel Straub Grip Type Coupling with Axial Restraint is used to join Metal Pipe to Metal Pipe or
Metal Pipe to Plastic Pipe or Plastic Pipe to Plastic Pipe .
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 .
2. Proudct Features :
* body, bolt, nuts made of stainless steel
* flexible pipe connection
* allow angular deflection but don't provide restraint
* anticorrosive
* easy installation and disassembly
* free of welding and fire risk

FAQ
1. Do Straub Coupling offer axial flexibility ?
Yes, Straub Flex Couplings offers axial flexibility in case the pipe ends move towards or away from each other .
These couplings can accommodate pipe shifts while ensuring a leak-tight seal for the passing media ?
2. Do these couplings require welding ?
No, straub couplings can be readily installed onto the pipes with simple tools and do not require welding for leak-tight seals.
These couplings can be fixed just by screwing bolts onto the pipe using a torque wrench.
3. Are Straub Coupling reusable ?
Yes, our Straub Coupling are reusable as they have wrap-around design.
4. What pipes are ideal for Straub Couplings ?
They are ideal for plain end pipes made from ductile iron, steel, stainless steel, PVC, FRP, CPP, CPVC, copper and concrete.
5. Do these couplings require lubrication?
No, straub couplings have built-in gaskets and do not require additional lubricants while installation.
6. What applications are these couplings suitable for ?
They are ideal for vacuum, pressure and suction lines.
