What Is HDPE Insulation Pipe?

HDPE insulation pipe is a kind of insulation pipe system using high density polyethylene (HDPE) as the outer protective layer. It usually consists of a three-layer structure:

· Inner layer: steel pipe for conveying medium.

· Intermediate layer: rigid foam insulation layer, usually polyurethane foam, used to reduce heat loss.

· Outer layer: High density polyethylene (HDPE) tube provides corrosion protection and mechanical strength.

HDPE insulation pipe has excellent insulation performance, corrosion resistance and long service life, and is widely used in urban heat supply network, petrochemical industry and other fields.
