22″ Dia. Riser Clamps

22″ Dia. Riser Clamps

All four riser clamps are manufactured from A-36 carbon steel plates and are coated with red oxide primer for rust prevention. They are 22″ in diameter with each plate measuring 2″ thick by 12″ wide by 65″ long. Each riser clamp is capable of supporting loads of up to 38,000 lb. and will be used in a power plant to support “downcomer” lines.

72″ I.D. Cryogenic Insulated Supports

72″ I.D. Cryogenic Insulated Supports

PT&P manufactured 72″ dia. insulated supports for temperatures as low as -260°F. The insulation is multi-layered comprised of polyurethane foam with a density of 20 PCF, a vapor barrier, an aluminum metal jacket, and acoustic pads. The acoustic pads are installed around the cold shoe to absorb vibration. The base and bearing plates are fabricated from carbon steel. The shoes will be used to support and insulate piping in a receiving & regassification plant and refinery.

164 Wide Base Sliding Insulated Supports

164 Wide Base Sliding Insulated Supports

The hot shoes are fabricated from A-36 carbon steel with 304 stainless steel slide plates. The 18″ dia. hot shoe has a maximum vertical load of 5500 lb. and the 24″ dia. hot shoe is capable of loads up to 13,750 lb. All the supports in this project are designed for temperatures of up to 1200°F. In addition to the insulation, these supports are capable of sliding axially or laterally as part of the piping system.

Special U-Type Constant Spring Supports

Special U-Type Constant Spring Supports

Special U-Type Constant Spring Supports

PT&P designed a constant load support system for a fluid tank with a load of 105,000 lb. over an area of 5′ W x 20′ L. To prevent twisting of the fluid container, the support system is designed to allow for “level” vertical movement. This was achieved by using a special system composed of three U-Type constant units. Each unit employs two springs working in parallel with a common large base plate and a load flange to support the entire 5′ width of the container.

Special U-Type Constant Spring Supports

The constants will support loads of 39,000 lb., 36,000 lb., and 30,000 lb., with a total travel of 4″ in the “upwards” direction. The spring coils were coated in neoprene, and all the other major components were hot dip galvanized to inhibit corrosion. These constants were constructed primarily from carbon steel with the use of stainless steel and PTFE, 25% glass filled slide plates.

78" Long 200 C-Type Constant Spring Assembly

Each constant spring support is designed to carry a 27,200 lb. load and provide 13″ downward travel. Special spring coils are used in order to reduce the entire length of the pipe hanger assembly. The frame and all internal moving components’ geometry are optimized as well to reduce the overall size. In total, the frame and casing combination measure 78″L x 21½”W x 33¾”H. The customer requested frame modification for special lug locations.

C-Type Variable Spring Support Assemblies

C-Type Variable Spring Support Assemblies

The C-Type variable spring assemblies range in overall length from 3′-2½” to 3′-5/8″, and the F-Type measures 1′-1½. The C-Type variables are designed with an operating load of 1653 lb. and a spring rate of 680 lb/in. The F-Type variable is designed with an operating load of 1511 lb. and a spring rate of 340 lb/in.

F-Type Variable Spring Support

F-Type Variable Spring Support

The variable supports will be utilized in a highly corrosive environment; therefore, Grade 316 stainless steel was used with a unique 3-coat paint system applied to the can housing.

Big Ton Spring Supports with Low Friction Rollers

Big Ton Spring Supports with Low Friction Rollers

PT&P fabricated several big ton spring assemblies consisting of two different models for a refinery expansion project in India. The larger model has an operating load of 25,590 lb. and a design travel of .420″ up.

Big Ton Spring Supports with Low Friction Rollers

Low Friction Rollers

The smaller model has an operating load of 12,100 lb. and a design travel of .443″ up. The big tons will be utilized to support substantial vertical loads while simultaneously providing a large platform to accommodate axial movement of the piping system across the load flange. Low friction rollers are installed to reduce the sliding friction between the load flange and the bottom section of a pipe shoe.
