OverviewHydraulic Snubber

Hydraulic Pipe Shock Absorber

It is a supporting device that curbs various types of troubles arising from dynamic loads generated in and outside of the power generation facility including main equipment and pipelines, while avoiding the creation of additional thermal stresses by absorbing the designed thermal displacement. The internal factors include vibrations transmitted through a rotating machine, the shock generated when the valves are opened and closed, and water hammering. The external include wind load, earthquake, explosion, etc.

The Need

To protect the pipe and main equipment against dynamic loads that are generated by internal and external causes.

ApplicationsMultiaxial Hydraulic Snubber

Multiaxial Hydraulic Pipe Shock Absorber

It is a supporting device that curbs various types of troubles arising from dynamic loads generated in & outside of the power generation facility including main equipment and pipelines, while avoiding the creation of additional thermal stresses by absorbing the designed thermal displacement. This Multiaxial hydraulic pipe shock absorber is so sophisticatedly designed and fabricated to respond to and absorb the shocks in random directions, breaking through the unilateral performance of the conventional shock absorber limited to responding to only one direction.
