Constant Spring Supports Designed with Special Lugs for Connecting to a Trolley

These PT&P 200 series constants are fabricated from A36 carbon steel. The 200-A constants measure 18.5″w x 20″H x 65″L and will support a 22,200 lb. load. They are modified to avoid interference with the structure by shortening the frame. The 200-C constants measure 18.5″w x 29″H x 80″L and will support a 32,000 lb. load. The constants have specially fabricated lugs to allow for a 3 ton trolley to connect with it.

March 28, 2011

Custom Elevated Pipe Shoe-Clamp Designed for a 12" Diameter Transfer Line in a Polymer Plant

PT&P designed and manufactured custom elevated pipe shoe-clamp supports for part of a palletizer transfer line in a polymer plant. The custom supports were designed to prevent cracking in the welds and grout base due to severe vibration in the line. The assemblies have an overall height of 48″ with an adjustable load column. The clamp-shoes are 13″ wide by 14″ long, and designed for a 12″ diameter aluminum pipe. The assemblies are carbon steel with a hot-dipped galvanize finish and include a unique laminated vibration dampening lining for the clamp.

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery
March 14, 2011

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery 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.

Hydraulic Snubbers (Fig. 511 AD) with Protective Boots Designed for a Hydro-sulfuric Acid Environment in a Geothermal Power Plant Hydraulic Snubbers (Fig. 511 AD) with Protective Boots Designed for a Hydro-sulfuric Acid Environment in a Geothermal Power Plant

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.
