Characterized by: includes high-temperature-resistant thermal insulation, lubricating layer, and elastic sealing components.

Insulation material: rigid polyurethane foam plastic.

2. Leak Detection Alarm Line: You may not be fully aware of what a leak detection alarm line is. It is actually an alarm wire embedded within the insulation layer of steel pipes. Once a leakage occurs at any part of the pipeline, the transmission through the alarm wire ensures the continuous operation of the heating network.

Insulation Effectiveness: Improved 4-9 times.

4. Porosity: Approximately 92% (the reason for low water absorption).

Parameters have already demonstrated its low thermal conductivity and low water absorption, which significantly reduces the overall thermal loss of heating pipelines, effectively addressing the issue of centralized heating in rural areas. It is suitable for insulating, sliding lubricating, and waterproofing the exposed ends of polyurethane insulated steel pipes used for high-temperature heat transfer ranging from 130℃ to 600℃.

The heat shrinkable sleeve joint is produced by flame shrinking imported heat shrinkable tape, which securely and flexibly connects the polyethylene outer sheath and the sleeve junction, ensuring both the joint's sealing and waterproof properties while also accommodating the pipe's axial displacement.

Electrical Resistance Welded Sleeve Fittings

The tensile strength at the welding joint ensures it is not less than the shell base material, providing stable and reliable performance, with easy operation.
