PT&P custom-designed and manufactured over 150 variable spring supports for a furnace application at an ammonia plant. The ammonia plant was the largest single train plant of its kind in the world for the leader in mineral-based commodity and specialized fertilizer production. As an important base to material for fertilizers, ammonia helps put food on the table as the engine of plant growth. Over 85% of anhydrous ammonia is used as fertilizer for the three primary nutrients of fertilizer: nitrogen, phosphates, and potash. The plant and the EPC for which these were designed and manufactured were in Europe highlighting Piping Technology and Products’ robust international footprint in the marketplace for over 47 years. We serve over 90% of the countries in the world covering almost all continents. Outside of use in the fertilizer industry, ammonia is positioned to have a key role in our renewable-based, lower carbon footprint hydrogen economy supporting on-board hydrogen carrier for fuel cell activities given its high capacity for hydrogen storage based on its molecular structure.

These furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. We also designed and manufactured 304 stainless steel pipe clamps to attach the furnace springs to catalysis tubes within the furnace. 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 before shipping.
