Low Linear Expansion Pipe Insulation Materials PIR Cryogenic Insulation 30 kg/m3

Our Low Linear Expansion PIR Cryogenic Insulation is specifically engineered to address the challenge of dimensional change in extreme temperature environments. Through specialized molecular design and manufacturing processes, its linear thermal expansion coefficient is significantly reduced to ≤ 70×10⁻⁶ m/(m*K). This key property ensures minimal dimensional change during drastic temperature fluctuations, from ambient to cryogenic levels (e.g., -196°C), effectively preventing critical issues like insulation layer cracking and joint gaps caused by contraction stress. It provides a fundamental guarantee for long-term, stable cryogenic performance.

• Exceptional Dimensional Stability: The ultra-low linear expansion coefficient is the core value, minimizing thermal expansion and contraction to preserve the integrity and sealing of the insulation system over long-term thermal cycling.
• Elimination of Cold Bridging & Energy Loss: Superior dimensional stability fundamentally prevents joint separation due to material shrinkage, effectively blocking cold bridge formation, ensuring energy efficiency, and reducing operating costs.
• Enhanced Durability & Low Maintenance: Reduces internal stress caused by temperature cycling, significantly lowering system maintenance requirements and long-term cost of ownership, while extending the service life of the entire insulation system.
• Consistent Long-Term Performance: Combined with its high closed-cell content (≥95%) and low thermal conductivity, it delivers persistent, high-efficiency thermal insulation while ensuring dimensional stability.

• Cryogenic & Low-Temperature Projects: LNG terminals & storage tanks, liquefaction plants, facilities for liquid ethylene/nitrogen/oxygen storage and transportation.
• High-Standard Process Piping: Cryogenic piping systems in chemical and air separation industries where stringent dimensional stability is required.
• Projects Where Long-Term Reliability is Critical: Core low-temperature storage areas in large-scale cold chain logistics centers, refrigerated holds in ocean-going vessels.
