Custom Variable Spring Supports Designed for a Furnace Application in an Ammonia Plant.
PT&P custom designed variable spring supports and hangers for a furnace application in an ammonia plant. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. The spring supports are designed to support loads ranging from 400 lb. to 12,500 lb. Over 150 spring coils underwent calibration test prior to fabrication and insertion into the variable support housing to ensure variance of less than 5%.
