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