STRAUB GRIP

STRAUB Grip coupling was launched in April 2018 and is the latest addition to STRAUB pipe coupling programme. STRAUB GRIP is an axial-restraint pipe coupling produced in 316L stainless steel with two bolt closing OD 21.0 to 168.30mm. It is the first pipe coupling in its class to be designed and manufactured without any welding process which further increases its corrosion resistance, which is a benefit to the marine industry shipbuilding and offshore platforms alike.

All STRAUB couplings designated with GRIP have axial restraint.

In order to be able to absorb the axial forces arising from the internal pressure, anchoring teeth engage in the relevant pipe material and provide a mechanical frictional connection. If the axial tensile load on the pipe increases due to increasing internal pressure, the teeth engage deeper into the pipe surface.
