This custom designed variable spring assembly is comprised of a standard PTP-1-160 type F variable spring with a supplementary extension and load flange with a stainless steel slide plate. The variable is fabricated entirely from carbon steel with a hot-dipped galvanize finish. The extension is schedule 40 pipe, 8″ in diameter and 12-5/16″ in height. The slide plate is fabricated from A240 grade stainless steel and is welded to the top of the load flange. This support will be used underneath a 16″ diameter pipe with a dummy leg. It is designed for 1/16″ vertical travel and 1/8″ horizontal travel for an oil refinery in Algeria.
These pipe clamp-guides were custom designed and fabricated for a 4″ pipe vertical run in an LNG facility. They measure 16″ from the bottom of the W-beam to the centerline of pipe and designed for temperatures up to 750°F. The clamp-guides were fabricated from carbon steel and include a hot-dipped galvanize finish.
