54&Quot; Dia. Pre-Insulated Pipe Shoes Custom Designed For A Pipeline In Texas

Pipe Shields/PT&P designed and manufactured pre-insulated pipe shoes for a 54″ diameter pipeline in a propane dehydrogenation unit within a chemical processing plant in Texas. The hot shoes are custom-designed with a wide base along with slide plates to accommodate lateral movement and axial movements of +/- 4 1/2″. We designed the hot shoes to include additional bolting along with bolting torque recommendations in order to help prevent slippage of the pipe inside the pipe shoe. We designed the supports to accommodate vertical loads up to 22,200 lb. and temperatures up to 1800°F. The outer part of the shoe was manufactured of hot-dipped galvanized carbon steel while the inner insulation material is 4″ thick high-density calcium silicate insulation.

Here’s a breakdown of their key purposes:

  1. Load Bearing and Movement: Insulated pipe supports are designed to carry the weight of the pipe while also accommodating necessary movement. This is important to prevent stress on the piping system and ensure its longevity.
  2. Insulation: In areas where regular pipe insulation cannot be installed, such as at support points, high density insulated pipe supports can both support the vertical load while providing a layer of insulation. This helps to maintain the temperature of the fluid flowing through the pipes and minimizes heat loss.
  3. Cost Efficiency: By reducing heat loss and minimizing the need for additional insulation materials, insulated pipe supports can help minimize the overall cost of field installation. Additionally, their pre-assembled nature saves installation time, further contributing to cost efficiency.
  4. Non-Welded Design: Unlike traditional supports that may require welding to attach to the pipe, insulated pipe supports are not welded. This simplifies installation and reduces the risk of damage to the pipe or insulation during the installation process.
  5. Shipment as Fully Assembled Units: Insulated pipe supports are typically shipped as fully assembled units, except for certain types like riser supports and anchor supports, which may require some welding during installation. This pre-assembly reduces the need for on-site assembly and ensures consistency in quality across installations.

Overall, insulated pipe supports offer a comprehensive solution for maintaining thermal efficiency, structural integrity, and cost-effectiveness in piping systems.

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.

Cryogenic Pipe Saddles Made for LNG Project

For this job, our client was a new entrant into the LNG engineering and design market space, and this was one of their capstone projects internally and for the marketplace.  Given PTP’s long history and experience concerning LNG pipe supports, we served as strategic partners in the engagement.  We identified that the client was using a pre-existing standard that underestimated the amount of Micarta® insulation thickness needed to provide adequate insulation for the facility.

PT&P engineers recognized that the insulation was not sufficient, and we tested the existing design using a test fixture we developed to demonstrate our concern.  PT&P utilized thermal scanning (infrared technology) to measure temperature at various locations around the insulated pipe support. As a result of our tests, our client corrected the concern, saving dollars, man hours, and scheduled project completion.

November 16, 2021

Cold Shoe Anchor Supports With 4&Quot; 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.

Ptp Fig 4800 Insulated Cold Shoe Anchor G10
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
