Insulation Solutions for Cryogenic and LNG Systems
Cryogenic and below-ambient pipe and tank temperatures can drop to -297°F, making a well-designed insulation system critical to ensure safe and efficient operations in an Liquefied Natural Gas (LNG) facility. At Johns Manville, we’re here to assist you with all the details you need to properly design, specify and install your cryogenic and LNG application.

Trymer PIRTrymer® 2500 and Trymer® 3000Trymer polyisocyanurate (PIR) is a rigid, closed cell, foam insulation specially formulated for use in the temperature range of -297F to 300F. Global LNG specifications require PIR densities of 40-45 kg/m3 (2.5-3.0 pcf). Trymer 2500 and Trymer 3000 satisfy the requirements of these specifications at their respective densities, and both have been successfully used in many LNG facilities around the world.
Vapor RetarderSaranex® CX Vapor Retarder Film and TapeSaranex CX films and tapes are made by co-extruding polyvinylidene chloride (PVDC) between two polymer film layers. The resultant products are very strong and durable. The low permeance of Saranex CX products, combined with the closed cell structure of Trymer foams, offer excellent resistance to both liquid water absorption and the high vapor drive associated with cryogenic temperatures.
Metal JacketingStainless Steel and Aluminum JacketingJohns Manville offers a complete metal jacketing system for mechanical and weather protection for your LNG system. Our high-quality aluminum and stainless steel jacketing are laminated with Polyfilm Moisture Barrier (PFMB) which provides the optimum resistance to corrosion.
Metal Jacketing FittingsStainless Steel and Aluminum Elbow FittingsElbow Covers are a crucial accessory to complement the metal jacketing. They help protect the insulation and underlying pipe from physical damage, UV exposure, corrosive environments, and water. They can also reduce the time and labor needed to install a metal jacketing system.
Industrial Mineral WoolMinWool-1200® Pipe InsulationComplying with noise level challenges can be solved with MinWool-1200 pipe insulation and tank wrap. Our mineral wool meets the highly stringent acoustical control requirements, ISO 15665, Class A through D, which measures insertion loss for pipe systems. Min-Wool 1200 is also water-repellent and performs at a service temperatures up 1200°F (650°C).
In an LNG application, if more heat is gained than can be removed by the refrigeration system, there is potential for the system to become pressurized as the LNG vaporizes. Minimizing heat gain is particularly important in cryogenic applications, like LNG, and why a well-designed insulation system is critical to ensuring safe and efficient operations in an LNG facility. Cryogenic and below-ambient piping and tanks should be insulated with a closed-cell foam insulation, and contain a vapor retarder with low permeability.
