Advantages of pipe insulation spraying
Improved Thermal Insulation Performance By 30%+
Closed-cell rate exceeding 90%, thermal conductivity as low as 0.02~0.024 W/(m·K), reducing energy consumption for heating and cooling.
One-time Molding, Seamless And Leak-proof
The spraying process directly adheres to the pipe wall, preventing cracking and delamination, and is resistant to rain and humid environments.
Strong Adhesion, No Need For Additional Support Structures
The foam has inherent adhesiveness, tightly wrapping the pipe, reducing the cost of labor and materials such as straps and supports.
Fast Construction Speed, More Efficient For Long-distance Pipelines
The spraying machine flow rate can reach 2–12 kg/min, allowing continuous construction of 60–105 meters of pipeline, significantly shortening the construction period.
Weather And Corrosion Resistant, Service Life Of Over 20 Years
Temperature resistant, aging resistant, and corrosion resistant, not easily damaged by acidic or alkaline soils or external environments.
Recommended Thickness Of Pipe Insulation Layer
Pipe Types | Medium temperature range | Recommended insulation thickness | Common Application Scenarios |
Cold Water Pipes / Air Conditioning Pipes | 5–15℃ | 20–40 mm | Anti-condensation, central air conditioning, cooling water pipes |
Hot Water Pipes | 40–60℃ | 30–50 mm | Domestic hot water, HVAC systems |
Steam Pipes | 80–120℃ | 40–80 mm | Industrial steam networks, heating pipelines |
High-Temperature Steam Pipes | 120–150℃+ | 60–120 mm | High-temperature pipelines in chemical, energy, and power plants |
Large Diameter Pipes (≥ DN200) | Depending on temperature: | Thickness +10–20 mm from the above | Long-distance transmission pipelines |
Ultra-Low Temperature Pipes (Cold Storage / Cold Chain) | -20℃–5℃ | 40–60 mm | Refrigeration pipes, cold storage piping |

- Our polyurethane tank insulation spray coating uses a high closed-cell formula with a closed-cell rate of over 90% and a thermal conductivity as low as 0.022 W/(m·K). This allows it to quickly form a dense, seamless insulation layer on the tank surface, significantly reducing heat loss.
- The material has a controllable expansion ratio and strong adhesion (≥ 0.3 MPa), maintaining uniform foaming on vertical, horizontal, and large curved tank surfaces without sagging or collapsing.
- The material has a temperature resistance range of -40℃ to 120℃, is resistant to aging, waterproof, and corrosion-resistant, and maintains stable insulation performance even after long-term use.
- We also offer customized formulas to better suit customer temperature requirements, construction environments, and tank types, resulting in more efficient and durable insulation.
