Product Description

      Description
 

1. Working Steel Pipe: Commonly made of seamless steel pipe, spiral steel pipe or straight seam steel pipe. Materials include carbon steel and stainless steel, capable of withstanding the pressure of the internal medium and the transportation requirements.
2. Polyurethane Insulation Layer: Composed of high-quality polyurethane foam material, it has an extremely low thermal conductivity, which can effectively reduce heat loss and ensure the insulation effect of the pipeline.
3. Outer Protective Pipe: Generally made of polyethylene plastic, which has good waterproof, anti-corrosion and mechanical strength, protecting the insulation layer from the influence of the external environment.

 

Product Performance Characteristics

 

1. Excellent Insulation Performance: Low thermal conductivity can significantly reduce energy consumption and improve energy utilization efficiency.
2. Outstanding Waterproof Performance: Effectively prevents water intrusion and ensures the long-term stable operation of the pipeline.
3. High Strength and Compressive Resistance: Capable of withstanding soil pressure and ground loads, adapting to various complex laying environments.
4. Corrosion Resistance: The outer protective pipe and insulation layer materials have good chemical corrosion resistance, prolonging the service life of the pipeline.
5. Convenient and Fast Construction: Construction methods such as prefabricated direct burial and on-site foaming can be adopted to reduce the construction period and cost.
