Manufacture

Multiaxial Hydraulic Snubber Multiaxial Hydraulic Pipe Shock Absorber

A supporting safeguard 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 sophistically designed and fabricated to respond to and absorb the shocks in random directions, breaking through the one-dimensional performance of the conventional shock absorber limited to responding to only one direction.

The Need

The need arose to design and engineer a compatible device that not only never restrains the movement of the piping even when 3D displacement different from the design breaks out, but also protects the piping and the main equipment from the strikes of dynamic loads of random directions.
