No Axial Restraint Stainless Steel Pipe Coupling

The multi-functional pipeline stainless steel pipe coupling has the advantage of no axial restraint, ensuring that the sealing of coupling is not affected during pipe expansion or contraction.

Feature

No axial force—when the pipe moves due to expansion or contraction, the seal is not affected.
suitable for shipbuilding, water supply, sewage treatment plants, and industrial piping.
Whether it is a suction line or a pressure line, you can install it safely and quickly.
It is for pipe outer diameters from 26.9mm to 2032mm.
