1. It improves the uniformity of the overall insulation layer density of the pipeline, compressive strength, and mechanical properties of the outer casing. 2. Reduces the axial eccentricity of the insulated pipe. 3. Reduces the thermal conductivity of the insulation layer and reduces energy loss. 4. The thickness of the insulation layer and the outer casing can be customized according to customer needs.

1. It is filled with rigid polyurethane foam to form a continuous and tight insulation layer, reducing heat loss, improving thermal transmission efficiency, and reducing energy consumption.

1. High production efficiency and can shorten the construction period. 2. High degree of mechanization and reduces human errors. 3. Reduces energy consumption and production costs and improves product quality.

1. Optical fiber can be used for detection and communication. 2. Long service life and simple maintenance. 3. Long detection distance, and a single host can cover more than 40 kilometers. 4. Optical fiber is a non-metallic conductor with strong anti-interference ability and high reliability. 5. Optical fiber detection is without electricity and is also suitable for special scenarios such as mines and fire protection.
