Cryogenic Supports With Micarta® Insulation For A Lng Facility In Australia

Type:  Insulated Pipe Supports “Cold Shoes”
Material:  CS | 304L SS | Micarta® Insulation
Size Ranges:  12-18″ L | 6-15″ W | 6-40″ H | 8-24″ Dia.
Design:  -320°F | Testing: PMI | Q.C. | MTR’s Provided

PT&P custom designed insulated supports for a cryogenic pipeline at an LNG facility in Australia. They are fabricated with 304L stainless steel plates and Micarta® G-10 insulation. Micarta® is designed to prevent LNG temperatures of -320°F from transferring to the base and surrounding pipe rack steel. The base plates are fabricated from carbon steel. These pipe saddles are designed to support pipes with dimensions ranging from 12″-18″ in length, 6″-15″ in width and 6″-40″ in height. The nominal pipe size range is 8″-24″ diameter. MTR’s were provided and non-destructive testing (PMI) was performed, along with standard Q.C. inspection prior to shipment.

As a key partner for many LNG projects globally, a number of our designs and products have been installed in various parts of the LNG facilities. They include:

  • Bird Screen
  • Constant Assemblies
  • FEA/Engineering Services
  • Expansion Joints Metal Bellows
  • Fabricated pipe shoes, guides, anchors
  • Field Services
  • Flanges, Strainers, paddle blinds, bleed rings
  • Hold-down clamps
  • Misc. Steel fabrication
  • Orifice plates
  • Pipe Hanger Hardware
  • Restriction orifice plates
  • Slide bearing plates
  • Snubbers/Sway braces/Sway struts
  • Spray Nozzles
  • Varibales Assemblies
  • Wear Pads
  • Troughs and Shrouds
  • Instrument spports
  • Portable Hinges/Manways

The current LNG production climate has had significant growth driven by increasing global demand for cleaner energy sources. Major LNG-producing countries, such as the United States, Australia, and Qatar, continue to invest in expanding their liquefaction capacity to meet this rising demand. Advancements in technology and innovation improve the efficiency and cost-effectiveness of LNG production. We have been a part of these efforts because of our breadth and depth of experience in LNG. Most recently we completed design, manufacture, and delivery of over 200 LNG troughs over 40 feet long to meet the newly established FERC requirements around spillage.

Insulated Pipe Supports for a High Temperature Pipeline by Pipe Shields, Inc.

Insulated Pipe Supports For A High Temp. Pipeline By Pipe Shields, Inc.

Type: Pre-Insulated Pipe Supports “Hot Shoes”
Size: 1″ to 3″ NPS | 1″ to 2″ Thick Insulation
Material: HDG Carbon Steel | Calcium Silicate
Design: Operating Temp.up to 1800°F
Operating Loads up to 1000 lb.
Movements of +/- 4-1/2″
Testing: Standard Q.C. Inspections

Pipe Shields, Inc., a division of PT&P, custom-designed insulated pipe supports for high temperatures in a chemical plant. These "hot shoes" are fabricated from A36 carbon steel and include a hot-dipped galvanized finish. They range in nominal pipe sizes from 1" to 3" and include 1"-2" thick calcium silicate insulation. The supports are designed for an operating temperature up to 1800°F and operating loads up to 1000 lb, with +/- 4 -1/2 movement. Quality control inspections were performed before shipping to Indiana.

Pipe Shields Inc. pioneered the design and manufacture of pre-insulated pipe supports, slides, guides and anchors and is a subsidiary of Piping Technology and Products, Inc. Our products are ubiquitous, serving diverse industries including hospitals, airports, semiconductor plants, automotive plants, EV battery plants, data centers, pharmaceutical plants, food processing, petrochemical plants, and power and renewable energy plants sometimes used in cold service lines and some dual temp lines between TCUs (temperature control units) and reactor jackets. Engineers often specify Pipe Shields and PT&P products as the foundation for designing various piping systems.

Last year we built over 50,000 units of this kind of support in our Houston-based manufacturing facility. We were the first in the industry to employ the use of high-speed manufacturing automation to facilitate the cutting of the high-density calcium silicate to meet tight deliveries required for the projects. The advent of computer-controlled cutting equipment has improved how we do things at PT&P. Integrating these advanced technologies has led to significant improvements in manufacturing processes, enabling unparalleled accuracy in cutting high-density insulation. Computer-controlled cutting equipment allows for intricate and complex designs that were once challenging or impossible to achieve manually. Automating cutting processes has not only reduced human error but also enhanced productivity by accelerating production speeds. Moreover, these systems provide a high level of repeatability, ensuring consistent quality across multiple iterations. Another benefit was that we were able to reduce the material waste generated by human cutting by roughly 10-15%, which allowed us to remain price-competitive on a global scale.

High Temperature Insulated Supports for an HP Steam Header

January 4, 2022

Ptp Hot Shoes 150370

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.
