Premium solutions engineered for high performance HVAC, cryogenic processes, and industrial pipeline projects.
Metal pipelines, whether conveying steam in petrochemical plants or carrying chilled water in commercial HVAC systems, operate under demanding thermodynamic stresses. The physical properties of steel, copper, and alloy pipes make them highly susceptible to rapid heat transfer and surface moisture condensation. This condensation leads to a critical industry challenge: Corrosion Under Insulation (CUI), which accounts for up to 40% of industrial piping maintenance expenses globally.
Modern elastomeric rubber foam insulation solves this problem by providing a continuous, closed-cell moisture barrier. With a closed-cell content exceeding 98%, our NBR/PVC formulations prevent water vapor from migrating to the cold metal surface. By maintaining a low thermal conductivity ($\lambda \le 0.034 \text{ W/m}\cdot\text{K}$ at 0°C), this insulation isolates the pipe's temperature, prevents condensation, and protects the system's structural integrity.
Integrating elastomeric material into metal piping systems also delivers significant soundproofing benefits. The elastomer's viscoelastic matrix dampens high-frequency mechanical vibration and controls fluid transport noise, ensuring compliance with strict industrial acoustic standards.
Our commitment to research and development helps us advance thermal efficiency and structural durability for modern infrastructure.
Using co-extruded NBR/PVC matrices with high vapor diffusion resistance (μ ≥ 10,000). This technology replaces older open-fiber insulations, offering reliable protection against moisture ingress on chilled metal pipe systems.
Developing specialized diolefin and nitrile rubber foam systems for ultra-low temperature environments (down to -200°C). These multi-layered cryogenic systems maintain flexibility and prevent thermal shock in LNG and liquid nitrogen piping.
Integrating silica aerogel structures into elastomeric sheets to reduce thermal conductivity to ≤ 0.028 W/m·K. We are also researching bio-based raw materials to minimize carbon emissions in manufacturing.
Different industries face unique environmental challenges. We engineer tailor-made piping systems to address these specific needs:
Condensation control on chilled water pipes and ductwork. Our NBR/PVC sheets and tubes prevent moisture dripping, protecting ceilings, wall structures, and indoor air quality.
Insulation solutions for ultra-low temperature applications (down to -200°C). Our multi-layered rubber foam systems prevent cracking and maintain mechanical flexibility under extreme thermal stress.
Thermal regulation for high-temperature and reactive fluids. Our closed-cell rubber protects carbon steel and stainless steel lines from CUI, maintaining stable chemical reactions.
Salt spray and corrosion-resistant insulation with tough cladding options. These solutions are built to withstand offshore environments and meet international maritime fire safety standards.
High-temperature EPDM-based pipe insulation that resists continuous UV radiation, ozone, and temperatures up to 150°C, ensuring long-term thermal efficiency.
Industrial rock wool blankets and high-density elastomeric systems for high-pressure steam pipes. These materials help minimize heat loss and provide vital protection for personnel.
