Aerogel LNG Insulation | Cryogenic Thermal Performance

Overview

Why Aerogel LNG Insulation is the Gold Standard for Cryogenic Systems

Managing thermal energy in liquefied natural gas (LNG) systems requires materials that can handle extreme sub-zero temperatures without losing their physical or insulating properties. Aerogel LNG Insulation from Henan Sanjie Pipe Mart Co., Ltd. is specifically engineered for these demanding environments. Our Aerogel LNG Insulation remains flexible and resilient down to -200°C, preventing the cracking and contraction common in traditional rigid foams. With a thermal conductivity of 0.018 W/(m`K), it provides the highest level of cold retention for LNG tanks and transport lines. Backed by 28 years of B2B expertise, our Aerogel LNG Insulation ensures your cryogenic assets remain safe and efficient across a global supply chain spanning 110+ countries.

◆ Exceptional Cold Retention at -200°C. Our Aerogel LNG Insulation is designed to thrive at the absolute limits of cryogenic operation. While traditional PIR or PUR foams can become brittle and crack at -200°C, the silica nanoporous structure of our aerogel remains completely flexible. This flexibility allows the Aerogel LNG Insulation to accommodate the massive thermal contraction that occurs when an LNG line is chilled. By maintaining a tight, seamless wrap, it prevents thermal bridging and ice formation. Data shows that our aerogel provides up to four times better thermal resistance than conventional cold insulation, ensuring minimal boil-off gas (BOG) and maximum transport efficiency.

◆ Integral Vapor Barrier and Hydrophobicity. Moisture is the enemy of any cryogenic system. Our Aerogel LNG Insulation features integrated hydrophobicity that prevents water from ever reaching the pipe surface. In the event of a breach in the outer jacketing, the Aerogel LNG Insulation itself acts as a secondary defense, repelling liquid water while remaining breathable for vapor. This prevents the "ice-jacking" effect where water freezes and expands inside the insulation, destroying its structure. By keeping the system dry and ice-free, our aerogel solutions extend the life of LNG infrastructure and reduce the energy needed for refrigeration.

◆ Space-Saving Design for LNG Carriers and Terminals. Onboard LNG carriers and within dense terminal pipe racks, space is a premium commodity. Aerogel LNG Insulation is 80% thinner than traditional multi-layer cold insulation systems. A 10mm layer of our aerogel provides the same cold-retention performance as 50mm of traditional materials. This reduction in volume allows for more compact piping layouts and increases the usable cargo space on vessels. The Aerogel LNG Insulation is also 85% lighter, reducing the structural load on pipe supports and making it easier to install in confined spaces during both new builds and maintenance dry-docks.

◆ Long-Term Stability and Maintenance-Free Service. Unlike organic foams that can degrade or settle over time, Aerogel LNG Insulation is an inorganic silica-based material with a design life of 25+ years. It does not compress under the weight of the jacketing or lose its thermal properties due to aging. Its tensile strength of ≥100 kPa ensures it can withstand the mechanical stresses of a moving ship or high-pressure pumping operations. Choosing our Aerogel LNG Insulation means investing in a "fit and forget" solution that eliminates the need for frequent and costly insulation replacement in hazardous cryogenic zones.

◆ Global Standards and Safety Compliance. Safety is paramount in the LNG industry, and our Aerogel LNG Insulation meets the most stringent international standards, including ASTM C1728. It is A1 non-combustible (GB 8624), providing critical fire protection for high-value cryogenic assets. Whether you are operating an export terminal in the Arctic or a regasification unit in the tropics, our Aerogel LNG Insulation provides consistent, reliable performance. Henan Sanjie's commitment to quality is reflected in our ISO 9001 and CE certifications, ensuring that every roll of Aerogel LNG Insulation delivered to your project meets the exact technical specifications required for safe LNG handling.
