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.

Pipeshields insulated supports 138055

Pipe Shields, Inc., a division of PT&P designed pre-insulated pipe supports for a high-temperature pipeline at a petrochemical plant overseas. This style of insulated support is designed to be compact, easy to install and eliminate the need for field welding. The insulation is 5-1/2″ thick utilizing 18 lb. and 28 lb. pcf high-density calcium silicate. The “hot shoes” are fabricated from carbon steel and hot-dipped galvanized for corrosion protection. They are rated for temperatures from +40°F to +1800°F. Q.C. inspections and dimensional tests were performed before an expedited shipment.

Such insulated supports are used for chilled water, hot water, and steam line applications in industries ranging from pharmaceutical, semiconductor, paper mills, chemical plants, data centers, biofuels, and food processing to name a few. Piping Technology and Products, through its subsidiary, industry leader, and pioneer, Pipe Shields, has supplied to all these markets in the USA and internationally for over 45 years. Most recently, we made a large investment to automate manufacturing in our Houston plant to increase throughput and yield to support our customers’ needs for just-in-time deliveries reducing cash requirements on projects.
