Fronek Anchor/Darling Enterprises, a division of PT&P, designed snubbers for a LNG facility in Texas. These Fig. 511 AD hydraulic snubbers range in size from 76″ – 85″ piston-to-piston and are fabricated from carbon steel. They are designed for a maximum load of 32,000 lb., 6″ stroke and have a 4″ diameter cylinder. Hydraulic snubbers are designed to protect the piping system when a sudden, heavy load is applied (such as an earthquake of high intensity), which can cause serious vibrations leading to damage and possible failure of the piping system. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipment
