PTP-2 Type-G variable spring support assemblies were designed and fabricated for an expansion project at an oil refinery. The G-type spring is comprised of two standard variable spring housing-coil subassemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions, which allows for use in applications with limited space or interferences. This particular assembly was provided with extra large channels because the specified C-C dimension of 59" exceeded the maximum (48") of our standard G-type variable springs. The housings, internal components and channels were fabricated from carbon steel, and spring steel was used for the coils. The assembly was designed for a total operating load of 24,014 lb. with a design travel of 0.76" upward.

Pedestals and Beams in Operation

The 54" suction line carrying gas to a gas compressor at a rate of 1.7 million lb./hr. developed a severe vibration. The deflections in the line were up to 3/4" and it was fully observable during operation.

PT&P designed and manufactured a special elevated hold-down clamp, including a unique laminated vibration dampening lining. The entire pipe hanger assembly stands 22' high and is coated with a carboline zinc finish. After installation and resumption of operations, the vibrations are now almost imperceptible.

Three custom "sling" pipe support assemblies fabricated from stainless steel were designed for an oil refinery in Louisiana. The assemblies are comprised of a 79.25" diameter custom saddle support and two horizontal travelers (Fig.270 PTP-4). They are capable of loads up to 44,000 lb., and were designed, fabricated and shipped in four weeks for expedited delivery.

Fronek Anchor/Darling, a division of PT&P, designed and manufactured hydraulic snubbers with protective boots for a hydro-sulfuric acid environment in a geothermal power plant. They measure 53-5/8" pin-to-pin with a 3-1/4" cylinder bore size and 6" stroke.

The snubbers are designed for an actual load of 15,400 lb., but have a rated load capacity of 20,000 lb. They are fabricated from carbon and alloy steel, and include two coats of epoxy-based paint. An activation velocity test was performed, along with a release rate and drag characteristics test.

100-C Constant Spring Supports with Double Lug Suspension

These figure 100 C-type constant springs were manufactured from A36 carbon steel for an oil refinery in Canada. Each constant was designed for 7" of travel with a load of 35,144 lb. They measure 21.5" W x 42" L x 80" H, and were specially designed to match a competitor’s dimensions in order to fit in the required application.

Ever wondered just how important it is to regularly walk through your plant to ensure proper functionality of all pipe supports in the piping system? Understanding the critical nature of properly functioning pipe supports and how they contribute to the overall system, one should thoroughly inspect each component for proper operation during different phases of the life of the unit.
