PT&P manufactured 48″ diameter pre-insulated pipe supports for a high-temperature pipeline at a phenol plant in Texas. Phenol is an important aromatic organic compound used in several products like plastics, nylon, epoxies, detergents, mouthwash, antiseptics, and other pharmaceutical drugs. PT&P has consistently supplied products to these types of plants for many years and has done work for most of the largest phenol plants in the world. The production of phenol from petroleum-derived feedstocks can involve temperatures, where large bore piping can reach 250°F. Phenols are used in a diverse range of end markets including construction, automotive, electronics, and fibre industries. Some other plants that utilize large bore piping at high temperatures, are Biofuels, Semiconductor, and Old Sands Extraction processing plants. These hot shoes, in particular, are designed for pipe sizes up to 48″ in diameter. They include 6″ thick by 4″ width calcium silicate insulation, hot-dipped galvanized steel, and are designed for a load of 7,000 lb. Standard quality tests were performed before shipment. At Piping Technology and Products, we can supply a wide range of different types of pipe supports to meet your design specifications. This enables our clients to order from one vendor as opposed to several different vendors to manage the supply chain for project success in the most cost-effective manner while keeping deliveries on time. This order consisted of six different types of supports such as variable assemblies, constant support assemblies, sway struts, and pre-insulated pipe supports along with associated “off the shelf” hardware items. We have served the piping industry for over 45 years providing a unique array of engineering and manufacturing experience to an ever-changing industry.

High-Temperature Supports Designed for a Petrochemical Plant
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.

Pre-Insulated pipe supports were designed for high-temperature service at an oil refinery for a client that specializes in the engineering and design of fired heaters, furnaces, pre-heaters, and heat recovery systems. These high-temperature pipe supports were fabricated from carbon steel and designed for pipe sizes ranging in 36” – 42” diameter and are not only used for new construction but also upgrades and revamps. The “hot shoes” were designed with the addition of “Spring Washers” (not shown here) to maintain consistent clamping force when the pipe expands and contracts. The insulation is 3″ thick and comprised of High-density Calcium Silicate (asbestos-free) structural inserts treated with water repellant. Standard quality tests were performed before shipment. Our hot shoes are used extensively in Refineries, Styrene Plants, Hydrogen Plants, LNG Facilities, Semiconductor Fabrication Facilities, and General Building Construction.
