faster construction speed

reduced energy costs

Polyurethane spraying machines are widely used in hot and cold water pipes, steam pipes, chemical pipelines, and urban heating networks, providing rapid, seamless, and weather-resistant coating. Our spraying machines offer a high flow rate output of 2–12 kg/min and can be connected to 60–105 meters of external heating pipelines, easily handling long-distance and complex construction conditions. No templates or additional supports are required, significantly reducing labor and construction time; the insulation layer is formed in one step and adheres tightly to the pipe surface.

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.

Accessories and Support

Electric air compressors

Suitable for environments with a stable power supply, such as factories and construction sites. They operate with low noise and are easy to maintain.

Diesel air compressors

Suitable for construction environments without power supply, powerful engine with a displacement of 970 L/min.

Diesel air compressors

Suitable for outdoor work or construction sites without a fixed power source. They offer strong power, wider adaptability, and can be used in conjunction with generators.

oil drum heater

Oil drum heating can quickly preheat polyurethane raw materials, reducing viscosity and improving fluidity. The heating temperature is adjustable from 0 to 200℃, suitable for 200L standard iron drums, with fast heating speed and uniform heating, preventing localized overheating.

Polyurethane planer

Polyurethane planers help remove excess foam, correct unevenness on sprayed surfaces, and achieve a clean, smooth surface before painting or panel installation. Lightweight and easy to control, these planers are suitable for applications such as wall insulation, roofing, and cold storage construction.

Mixer

The mixer is used to quickly and evenly mix polyurethane raw materials, ensuring that the liquid is fully blended before use, avoiding stratification and sedimentation, and improving foaming stability and construction effect.

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.

How to install spray foam machine

The following checks should be made before operation.

1. All joints from the host to the gun do not leak air or material,
2. be sure to separate A material and B material from the pump to the gun of the whole input pipeline, so as not to cause the whole system paralysis,
3.there should be safe grounding and leakage protection.
4. When the equipment stops working, the heating system should be tumed off and the power supply should be disconnected in time to avoid the decline of foaming quality caused by too long heating time.

Yongjia's price is 30% cheaper than Europe, but the quality is higher than European equipment

PU Spray foam machine pipe insulation Success Stories

A Russian company undertook an industrial pipeline insulation project. The client required a uniform, cut-resistant, and solvent-resistant polyurethane coating on the pipeline surface. The client used our polyurethane spraying machine for the application. The on-site operation was smooth, the material had good flowability, and the sprayed foam layer adhered tightly to the pipeline surface with uniform thickness, meeting high insulation standards. Upon completion, the client was very satisfied with the equipment performance and the application results.
