PE-RT II heat supply pipe is a new type of heat resistant polyethylene (PE-RT II) thermal insulation composite plastic pipe. PE-RT II heat supply pipe has excellent performance and is used in the secondary pipe network system of urban central heating. PE-RT II heat supply pipe mainly consists of three parts: the outer layer is hdpe high-density polyethylene pipe, the middle layer is polyurethane foam insulation layer, and the inner layer is working pipe PE-RT II pipe
PE-RT II heating pipe structure:

Part 1: Outer layer (outer protective tube)
The outer protective tube is the outer layer of the insulation layer, which blocks the damage and influence of external forces and environment on the insulation material.
Part 2: Intermediate layer (polyurethane insulation layer)
The insulation layer is a layer of insulation material set between the working pipe and the outer protective pipe to maintain the temperature of the medium transported by the pipeline.
Part Three: Inner Layer (Work Tube)PE-RT Type II Pipe

Work pipe is a type of insulation composite plastic pipe used for conveying media.
