Custom Compact Springs Designed to Support a Storage Tank

Type: Compact Spring Supports
Material: A-36 Carbon Steel | HDG | Stainless Steel
Design: 0.25″ Movement (upward) | 5,000 lb. Load
Testing: Load and Travel Testing

These compact spring supports were custom designed to support a storage tank at a facility in Texas. The housing was fabricated from A-36 carbon steel and hot-dipped galvanized to protect them against corrosion. The disc springs are engineered using the stainless steel Belleville disc springs designed for large loads but small movements. In this case, the springs are designed to support a load of 5,000 lb. and movement of 0.25″ (upward). Each assembly underwent load testing prior to shipment.

Variable Spring Supports for a Furnace application at an Ammonia Plant

Type: Variable Spring Supports
Material: Carbon Steel | Red-Oxide Primer | 304 SS
Design: 3,000 lb./in.
Testing: Load Test

PT&P custom designed variable spring support assemblies for a furnace application at an ammonia plant. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. The pipe clamps are fabricated from 304 stainless steel. They are designed to support a cold load of almost 3,000 lb./in. while operating in an area where temperatures are higher than ambient. There were a total of 173 assemblies fabricated for this project, 152 variable hangers, 3 constant spring supports, 6 ball joint rigid struts, and 12 rigid rod hangers. Special load tests were performed prior to shipping.

Big Ton Spring Supports Designed for a 98,250 lb. Load

Type: Big Ton Spring Supports
Size: 29″ wide x 110″ long x 35″ high
Material: HDG Carbon Steel | A193 Gr. B7 Travel Stops and Load Column
Design: 98,250 lb. | 1-3/4″ Upward
Testing: Load Cell Test

This big ton spring support assembly was designed for a facility in Kansas. The assemblies are fabricated from hot-dipped galvanized carbon steel and include neoprene coated springs coils. The travel stops and load column material is A193 Gr. B7. The units measure 29″ wide x 110″ long x 35″ high and are capable of supporting loads up to 98,250 lb. while accommodating movements from 1-3/4″ upward. The big tons were tested with a load cell to insure proper operation throughout the big ton’s operating range.

Compact Springs Designed for an Oil Refinery Expansion Project

Type: Compact Spring Supports (Disc Springs)
Material: Carbon Steel | PTFE, 25% Glass-Filled
Design: Movement: 1/32″ to 1/4″ | Load: 12,000 lb.
Testing: Standard Spring Rate & Calibration Tests

These compact spring supports were custom designed for an oil refinery expansion project. They will be installed underneath a heat exchanger supporting a load up to 12,000 lb. The space available was limited to 3″ in height and the movements ranged from 1/32″ to 1/4″. These compact springs are fabricated from carbon steel and utilize engineered Belleville (disc spring) washers. 25% glass-filled (PTFE) slide plates are bonded to the top of the load flange and provide a low coefficient of friction.

Variable Spring Supports Designed for a Furnace in Trinidad

Variable Spring Supports Designed for a Furnace in Trinidad

Type: F-Type Variable Spring Supports (Furnace Springs)
Material: Carbon Steel | Red Oxide Primer
Design: Movement: 1/2 “| Load: 398 lb. | Spring Rate: 84 lb./in.
Testing: Standard Spring Rate & Calibration Tests

PT&P designed and manufactured these F-Type variable spring supports for use in a furnace at a facility in Trinidad. We manufactured these furnace springs for an operating load of 398 lb., a movement up to 1/2″, and a springs rate of 84 lb./in. They are fabricated from carbon steel with a red oxide primer coating to protect against corrosion. Customer specifications required a modified, installed height, while maintaining the spring rate, operating load and install load. In order to accomplish this, PT&P designed, manufactured and attached, to each spring, a pedestal to accomplish the increased installed height.
