A-Type Variable Spring Supports with a Load Capacity of 596 lb.
Drawing of Variable Spring
Fabricated from A-36 carbon steel, these PTP-4 A-Type variable spring supports measure 6 5/8″ OD x 19 9/16″ in length with an installed load of 596 lb. They have a spring rate of 56 lb/in., and a downward travel of 1.375″. These supports are designed to suspend from a rod that is threaded through the upper portion of the variable (see Fig. PTP-4). This particular design is generally used to keep the variable further away from the beam to avoid interference.

Stainless Steel Trunnions for an LNG Plant
These stainless steel trunnions are designed to support a vertical pipe used in an LNG plant. The trunnions will support stainless steel pipes with diameters ranging between 24″ and 42″. The diameter of the trunnions ranges in size from 12″ to 22″. The overall length is 34″. All of the weld seams were 100% dye-penetrant tested before being shipped to the plant.

63" x 63" Big Ton Springs for an Oil Refinery
The base measures 63 inches square while the top load flange measures 55 inches square. One of the springs has an overall height of 22-7/16″ and the other an overall height of 28-5/8″. Both big ton springs are custom designed and fabricated from carbon steel with a hot-dipped galvanized finish. The top of the load flange is covered by a stainless steel slide plate. These big ton springs will be used to support heavy (in excess of 100,000 lb.) loads where a standard variable spring would be undersized.
One of the big ton springs is designed with a operating load of 126,000 lb. and the other with an operating load of 225,000 lb. Prior to fabrication, all of the coils, within the frame, were individually tested to insure correct spring rate and load capacity. After the units are fabricated, the entire assembly is tested throughout the entire load/travel range.

Permali Cold Shoes for Carbon Steel Pipe
These cold shoes are anchors supports and fabricated with A-36 carbon steel and permali block insulation. The carbon steel is hot-dipped galvanized for protection and longevity of the cold shoe. The permali block insulation, between the base plate and the saddle, functions to insulate the supporting structure from extreme cold temperatures of the pipe.
These cold shoes are designed for pipes ranging in size from 6″ to 14″. The assemblies are capable of loads ranging from 194,000 lb. to 291,000 lb.

43" Angulating Constants for a Power Plant in Utah
The design of this constant requires that it be connected by pins from the top and from the bottom to allow it to angulate. The constant assemblies are fabricated from A36 carbon steel. The constants measure between 23″ and 43″ in length with a take-off between 29″ and 55″. The load range is 60 lb. to 2,605 lb. and each constant assembly underwent standard load and travel testing.

Injection-Molded Anchors for an LNG Plant
6" NPS Anchors
These supports are used in a re-gasification terminal and are designed for -29°C ambient and -196°C fluid temperatures. The polyurethane foam insulation is injected into a mold with a pipe spool in place to ensure maximum fit. The pipe anchors are made from 516 Grade 70-N carbon steel. These supports were put through Finite Element Analysis and inspected by our Quality Control Department.
