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.

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

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.
