Type: Pre-Insulated Pipe Supports for High Temperatures “Hot Shoes”
Size: 2″ – 12″ dia. | 12″, 15″, 18″ Long | 4″ and 6″ BOP
Material: Carbon Steel | Thin Blanket Insulation | High-Density Calcium Silicate
Testing: Standard Q.C. Inspection | ANSYS Simulation

Piping Technology & Products custom-designed and fabricated pre-insulated pipe supports for a high-temperature application in an HP Steam Header located in Texas. Pre-insulated supports such as these are used in several applications ranging from semiconductor plants (addressing the current computer chip shortage) to high-temperature pipelines within plants that produce biofuels and solar power. These hot shoes range in size from 2″ to 12″ in diameter and are 12″, 15″ and 18″ long, with BOP of 4″ and 6″. The supports include a thin blanket insulation used in combination with a high-density calcium silicate insulation material. Utilizing the blanket insulation in combination with the high-density calcium silicate insulation material helped to reduce the overall costs, increased the K-factor, while also reducing the weight of these supports. We custom designed these supports using ANSYS engineering simulation for temperatures up to 844°F with an operating load up to 17,965 lb. at 732 psig. A total of 95 supports were manufactured for this project, including pipe hangers, pipe shoes with insulation and trunnion supports, as well as pipe shoe clamps without insulation. All supports were visually inspected by our Quality Control department. Piping Technology & Products offers excellent manufacturing expertise and our sister company, Pipe Shields Inc., has the engineering design and experience to assist in the development of custom pre-insulated supports or advise which of our many different supports contained in our new catalog is best for your next major project.

Cold Shoe Anchor Supports with 4″ Thick G10 Micarta® Insulation
November 16, 2021

Cold Shoe Anchor Supports with 4" Thick G10 Micarta® Insulation

PT&P Cold Shoe Anchors are designed to support pipe sizes ranging from 12″ to 72″ in diameter. In this case, the supports were custom designed for one of the largest nitrogen generation systems for LNG in the Southern Hemisphere. The project employed a modular approach to its execution which included the assembly of large, complex, and heavy Process Modules as well as simple and relatively light Yard Rack Modules.

The saddles are fabricated from A240-Gr. 304L stainless steel and the base plates are fabricated from galvanized A516 Gr. 70N carbon steel. The insulation is 4″ thick G10 Micarta® material and capable of insulating from temperatures down to -300°F. G10 shoes are welded directly to the pipe spool, inspected, and tested prior to shipping which saves field installation and inspection time. G10 supports are also pretty durable making handling, transportation, and storage trouble-free. G10 Micarta® supports have an insignificant water/moisture absorption rate, meaning there is no structural deterioration in adverse weather, especially in the wake of heavy rain and storms.

G10 Micarta® supports involve fewer steps to manufacture allowing PT&P to support just in time lead times for fast-paced dynamic projects. PT&P has designed, extensively tested, and manufactured on G10 Micarta shoes for over 15 years. G10 is a preferred choice in cryogenic applications and demanding LNG environments for the following reasons:

  • Impervious to water absorption–Water intrusion into the system degrades performance and leads to many problems such as ice formation.
  • Superior Tensile and Flexural strength
  • Low Capital Expenses: Reduced field welding time, material cost, travel time, and field installation cost
  • Construction/Installation Savings: G10 pipe shoes can be sent to the pipe fabricator and welded directly to the pipe spool allowing for no inspection and testing requirements in the field.
  • Easy, trouble-free handling, transportation, and storage
  • Longer installation life and reduced maintenance needs

Pre-Insulated Pipe Supports for High Temperatures at a Phenol Plant in Texas
October 4, 2021

Pre-Insulated Pipe Supports for High Temperatures at a Phenol Plant in Texas

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.

Custom High-Temperature Pre-Insulated Pipe Support for a Chemical Plant

This custom-designed insulated pipe support will be used for a high-temperature pipeline at a chemical plant in Canada. This hot shoe was customized without the u-base and modified with an extended length. It will be used to prevent the movement of a 6″ diameter pipe in the axial direction. Axial stops will be welded to the clamp O.D. in the field. The plates are 11-5/8″ O.D. x 48″ in length and fabricated from A36 carbon steel. The insulation is 2″ thick high-density calcium silicate and well-suited for temperatures up to 1200°F. Q.C. inspections and dimensional tests were performed prior to shipping.

High-Temperature Pre-Insulated Pipe Supports Designed for 42" Dia. Pipelines

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.
