Product Features

Polyurethane insulation pipe (black jacket insulation pipe, polyurethane insulation pipe and its connecting parts, including insulation tee, insulation reducer, insulation elbow, insulation bend pipe, insulation fixed joints, etc.) is suitable for urban heating, electric heating, water transmission and insulation, oil pipeline, plumbing pipe, air conditioning pipe, electric power pipe, thermal pipe...Pipeline insulation buried in the project is widely used. It has many advantages, such as environmental protection and energy saving, anti-corrosion and heat preservation, anti-freezing and cold resistance, economy and beauty, and reducing heat loss.

Prefabricated buried insulation pipe is mainly composed of Three parts. (1) working steel pipes: according to the technical requirements of the conveying medium, slit steel pipes, seamless steel pipes and double-sided submerged arc spiral welded steel pipes are adopted respectively. (2) insulation layer: rigid polyurethane foam is used. (3) protective shell: use high-density polyethylene or glass fiber reinforced plastics.
