DYNAMIC RESTRAINTS

CPA’s pipe support offering includes dynamic restraints (hydraulic snubbers and rigid struts) as well as connecting stiff clamps.

These photos show feature CPA’s hydraulic snubber (as well as our handsome model/sales manager Michael in Taiwan). Our largest snubbers possess a load carrying capacity of up to 1000 Kn.

Under the normal operating conditions of a piping system, hydraulic snubbers accommodate the required displacement of the piping. However, during a dynamic event (such as an earthquake, rapid valve closure, two phase flow or relief valve discharge) the snubbers lock the piping system in place thus protecting it from excessive deflections /stresses.

The CPA hydraulic snubber incorporates a ‘through rod’ design. This provides the following benefits over competitor products:

No need for an external reservoir – the hydraulic fluid volume does not change, as a result of the existence of the piston rod on either side of the piston.

Strong design – the piston rod is supported at both ends to avoid ‘knuckling’ and subsequent wear on the bearings.

Small diameter – efficient design and no external reservoir results in a compact product.

Enables the snubber to be installed in any orientation.

Results in robust product with strong and reliable performance.
