Variable Spring Hangers Designed For A Biofuels Plant

PT&P designed and fabricated B-Type variable spring support assemblies for a biofuels plant. The variables will support pipelines that are involved in the process of converting feedstock into low-carbon synthetic crude oil. Primary biofuels are bioethanol and biodiesel. PT&P specializes in manufacturing pipe supports for high temperatures (above 750°F) applications. These variable springs will support loads up to 953 lb., insulated piping up to 1625°F, and with 1.5” upwards movement. A custom-designed 4-bolt riser clamp fabricated from A36 carbon steel for a 3” diameter pipe was also supplied for this order and used at another location in the plant. The rest of the variable spring assemblies utilized custom-designed 2-bolt pipe clamps manufactured from A240 316L stainless steel plate with A 193 GR. B8M CL.1 bolting for high temperatures. Since these variable springs were located outside the firebox and not exposed to high temperatures, they were fabricated from A36 carbon steel and hot-dipped galvanized for corrosion protection. Load and travel tests, along with Q.C. inspections were performed before shipment.

Load and travel tests, along with Q.C. inspections were performed before shipment. Biofuels are expected to double their market share by 2027. Biofuels are a subset of the new emerging demand and regulatory shift to renewables being seen in the energy sector. In addition to biofuels, other renewables include energy from solar, wind, hydroelectric, ocean, geothermal, and hydrogen sources. There has been a change in strategy for many refineries accelerated by the downturn due to COVID, to convert traditional fossil fuel refineries to renewables. With expertise and over 45 years of experience, PT&P is well-positioned to serve its customers and emerging players in the renewable energy sector. Piping Technology & Product’s specialty is the design and fabrication of products like furnace springs, constants, customized clamps, and hardware in supporting high-temperature headers and radiant coils within fired heaters.
