Precision-Engineered Cryogenic Pipe Supports
When dealing with cryogenic piping systems, thermal isolation is more than a preference, it’s a necessity.
That’s where cold shoes come in. Cold shoes are specialized pre-insulated pipe supports designed to prevent the transfer of extreme cold from the pipe to surrounding structures.
These supports are critical in preserving structural integrity and ensuring safe operation in cryogenic environments, withstanding temperatures as low as -300°F.
At Piping Technology & Products, we manufacture cold shoes with high-density polyurethane foam (PUF) insulation. Known for its superior thermal resistance, low weight, and adaptability, PUF is ideal for minimizing heat transfer while maintaining structural support.
Built for Extreme Conditions — and Big Pipelines
In a project for a Liquefied Natural Gas (LNG) facility in Mozambique, we fabricated a series of custom-designed cryogenic pipe supports engineered for performance in high-demand applications.
Key Product Specs:
- Pipe Diameters: 30″ to 72″
- Support Dimensions: 45″ to 88″ high, 42-1/2″ to 85-1/2″ wide, 28″ to 33″ long
- Insulation: 5″ to 6″ thick high-density polyurethane foam
- Materials: Carbon steel with hot-dip galvanized finish; aluminized steel jacket for vapor barrier
Polyurethane foam insulation (PUF) was selected for its reliability under thermal stress and ability to be customized to various pipe sizes.
Our in-house engineering and fabrication capabilities allow us to deliver high-performance supports that meet exact project specifications while minimizing installation and maintenance issues.
Designed for the LNG Industry
LNG facilities demand exceptional durability, reliable thermal performance, and insulation systems that prevent heat ingress into cryogenic pipelines. Without proper cryogenic pipe supports like cold shoes, LNG systems face a range of serious challenges:
- Boil-Off Gas (BOG): Heat ingress can cause LNG to vaporize, leading to pressure buildup and product loss.
- Frost and Ice Formation: External surfaces can ice over, causing structural stress and safety hazards for workers.
- Material Embrittlement: Non-cryogenic components may crack or fail when exposed to ultra-low temperatures.
- Increased Energy Use: Systems become less efficient, requiring more power to maintain cryogenic conditions.
- Environmental and Safety Risks: Uninsulated lines can leak LNG vapor, potentially forming flammable gas clouds.
These issues drive up costs, introduce safety concerns, and reduce system reliability.
From small-bore lines to massive pipe systems like those in this project, our cold shoes are engineered to prevent these outcomes at LNG operating plants.
With high-density PUF insulation and heavy-duty construction, they support large-diameter lines while minimizing thermal transfer, resisting corrosion, and protecting the integrity of LNG infrastructure.
