Below are 7 sections full of resources to learn more about cryogenic and LNG system design, and the benefits of using Trymer® Polyisocyanurate (PIR) insulation:
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.
Minimizing heat gain is particularly important in cryogenic applications, like LNG, so an insulation material that is both thermally efficient and moisture resistant is critical. When specifying a pipe insulation system, it’s important to evaluate all of the variables that contribute to optimum performance and the best long-term value. Connect with a Technical Expert.
Trymer is a polyisocyanurate (PIR), closed-cell, foam insulation for industrial pipes, tanks, vessels, and equipment used in cryogenic and LNG applications. Trymer PIR can be used on applications that operate at temperatures ranging from -297°F to 300°F (-183°C to 148°C). JM produces Trymer PIR in a variety of densities and compressive strengths to ensure the performance characteristics of the product meet the unique demands of LNG applications. Trymer PIR features a k-factor of 0.19 BTU · in/hr · ft2 · °F at 75°F mean temperature (0.027 W/m · °C at 24°C), one of the lowest ambient k-factors among insulations used in cryogenic applications.
Cryogenic tanks are an essential part for many industries, as they are a key element to store certain gases crucial for diverse processes. In light of such importance, we take a look at the different possibilities in the current cryogenic tanks market and provide 4 key questions to answer before acquiring a cryogenic container.
Cryogenic tanks are a type of industrial storage tank ideal for situations where large quantities of gas need to be stored in liquid form.
They are the right solution to store substances such as Liquid Oxygen, Liquid Nitrogen, Argon, C02, LNG, LPG, Liquid Hydrogen, etc, all of which must be stored at very low temperatures in order to maintain their properties. Thus, it’s common to hear of a cryogenic oxygen tank, a LNG cryogenic tank, and so forth.
As more and more industries require the gases mentioned above, demand for cryogenic tanks keeps growing and is projected to grow at a higher rate than 5% CAGR between and .
The main characteristics of an adequate cryogenic storage tank include:

While cryogenic tanks have this basic structure in common, it’s possible to distinguish between two types of cryogenic container:
When choosing cryogenic tanks, companies must consider what substances they need to store, and communicate it to the tanks manufacturer.
Different substances will require a different tank shape and design, so that it perfectly adapts to the cryogenic liquid it will need to store.
Some common substances that require a cryogenic container include:
Different companies will be in need of different tank sizes, depending on their substance demand and use, among other factors. At Cryospain we are specialized in tanks for large quantities >500 m3
Stainless steel and carbon steel are the main two materials for building cryogenic tanks. At the same time, different insulating materials can be used: from cellular glass, to rockwool and expanded perlite. Thus, each project must be studied separately, in order to ensure the right materials are used.
Other criteria to pick the right cryogenic tanks can include:
