Cryogenic Pipe Supports Designed For A Petrochemical Complex In Louisiana

Type: Pre-Insulated Pipe Supports for Cryogenic Application
Size: 46″ – 52″ Diameter Range | 10 lb. & 20 lb. Density PUF Foam
Material: Hot-dipped Galvanized Carbon Steel | PUF | Polyester Film & Aluminum Foil
Testing: Dimensional and Visual Inspection

These cold shoe pre-insulated pipe supports were designed for a cryogenic pipeline at a petrochemical complex in Louisiana. These supports range in size from 46" to 52" in diameter and are engineered for temperatures as low as -20°F. The supports feature a dual-density polyurethane foam (PUF) insulation: the top portion has a density of 10 lb., while the bottom is 20 lb. high-density PUF. The shoe and bearing plates are constructed from carbon steel and finished with hot-dip galvanization for durability and corrosion protection. These cold shoes also include a vapor barrier, consisting of a three-layer lamination of polyester film and aluminum foil, ensuring effective insulation. Standard quality control tests were conducted on all units before shipment to ensure compliance with performance standards.

This type of cold shoe design is also utilized on liquefied natural gas (LNG) storage tanks. Liquefied Natural Gas (LNG) storage tanks are specialized containers designed to store LNG, which is natural gas that has been cooled to a liquid state at approximately -260°F (-162°C). This liquefaction process reduces the volume of the gas by about 600 times, making it much more efficient to store and transport. Most LNG tanks are double-walled with an inner and outer shell. The inner shell, typically made of stainless steel or nickel alloy, contains the LNG, while the outer shell, often made of carbon steel or concrete, provides structural support and can store up to 200,000 cubic meters or more.

Our pre-insulated pipe support portfolio is the most complete in terms of the types of insulation we work with and the industries we serve. We design and manufacture supports with:

  1. Permali (Cold Shoe) – Temperature range: Ambient to -300°F – Compressive strength: 22,000 PSI – Tensile strength: 28,000 PSI **

  2. Micarta (Cold Shoe) – Temperature range: Ambient to -300°F – Compressive strength: 39,000 PSI – Tensile strength: 12,000 PSI **

  3. Polyurethane (Cold Shoe) – Temperature range: Ambient to -300°F – Compressive strength: 200 PSI to 911 PSI (dependent on density) – Tensile strength: 12,000 PSI

  4. Foam Glass (Cold or Hot Shoe)** – Temperature range: -450°F to 1,000°F – Compressive strength: 100 PSI – Tensile strength: 50 PSI

  5. Marinite (Hot Shoe) – Temperature range: Ambient to 1,200°F – Compressive strength: 2,000 PSI – Tensile strength: 500 PSI **F. Calcium Silicate (Hot Shoe)** – Temperature range: Ambient to 1,200°F – Compressive strength: 160 PSI – Tensile strength: 50 PSI

The supports can be manufactured with carbon steel or stainless or the material the project may require. The thrush plates can be hastelloy, inconel, etc depending on the pipe material. Working with different metallurgies is a part of standard manufacturing protocols.

These supports are deployed in semiconductor, petrochemical, nuclear, blue hydrogen, blue ammonia, solar, LNG, pharma, data centers, automotive, mines, pulp/paper, building materials, food processing and EV battery plants.

54" Dia. Pre-Insulated Pipe Shoes Custom Designed for a Pipeline in Texas

May 14, 2024

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.

August 1, 2023

Insulated Pipe Supports for Low Temperatures

PT&P manufactured cryogenic pipe saddles for LNG transportation pipelines. These types of insulated supports have been utilized in LNG plants around the world. Insulated supports are also used on cold piping in semiconductor plants or plants that make batteries to eliminate condensation.

Cryogenic Pipe Saddles With Micarta® G-10 Insulation For Lng Service

A cold shoe is a pipe support used for cryogenic applications where the transfer of cold temps from the pipeline to the surrounding steel pipe rack is not desirable. These supports can be used for temperatures down to -320° Fahrenheit.  This particular type of insulated pipe saddle assembly was fabricated with a carbon steel base plate, 304L stainless steel saddle, and an insulation block. The overall size ranges from 25” x 19” x 12-¾” to 29” x 25” x 13-3/8”. These pipe shoes were manufactured to support pipe sizes ranging in diameter from 36″ to 42″ NPS.

For additional information about Insulated Pipe Supports go to our product page.

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.

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

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
