3 Layer Design
The high performance of heat resistant PE insulation composite pipe is suitable for the urban central heating system. It is mainly composed of 3 layers:
It is the outmost layer preventing external force and damages from the environment.
Thermo Insulation Layer
It is in the middle to keep the temperature of hot gas carried in the composite pipes for heating systems.
Working Pipe Layer
It is the innermost layer directly taking the work of hot gas transmission.
