Custom Sway Strut and Pipe Clamp Assemblies for an LNG Plant in Australia

PT&P fabricated and designed 52 of these custom sway strut assemblies for a liquid natural gas plant in Australia. These are manufactured from carbon steel with 304 stainless steel pins. The pipe sizes range from 2”-72” diameter, with a total length ranging from 27” to 137”. The sway struts are fabricated to restrain either tensile or compressive force in one direction while providing for movement due to thermal expansion or contraction in another direction. These sway struts have an operating temperature of 650°F and are designed for operating loads ranging of 650 lb. to 120,000 lb.

Hydraulic Snubbers Designed for an LNG Facility in Texas

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

Hydraulic Snubbers Designed for a Geothermal Facility

Fronek Anchor/Darling Enterprises, a division of PT&P designed and fabricated hydraulic snubbers for a geothermal facility in California. The Fig. 510 AD snubbers ranged in size from 34-3/4″ to 37-5/8″ piston-to-piston and were designed for a 50,000 lb. maximum load, 5″ cylinder size and a 6″ stroke. The Fig. 511 AD snubbers ranged in size from 56-15/16″ to 59-5/16″ P-P and were designed for a 20,000 lb. maximum load, 2-1/2″ cylinder size and a 6″ stroke. 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 complete destruction. A custom three-bolt pipe clamp fabricated from carbon steel was designed to fit in a limited space. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipment.
