Thermal Insulation Pipe, PUR Foam HDPE Jacket Pipe Canghai Nulear
Product Description
Polyurethane insulated pipes are composite finished pipes, primarily consisting of an outer protective layer, an insulation layer, a leak-proof layer, and other components.Typically made from materials such as polyethylene, galvanized steel sheets, or stainless steel plates, they serve to protect the insulation material and pipeline, preventing erosion and damage from the external environment.As the core component of polyurethane insulated pipes, polyurethane foam is commonly used as the insulation material, with its density and thickness adjustable according to specific thermal insulation requirements.Polyurethane foam exhibits excellent heat insulation and pressure resistance, effectively reducing heat conduction and heat loss.In some cases, a leak-proof layer is also incorporated into polyurethane insulated pipes to prevent pipeline leakage, ensuring the safe operation of the pipeline system.
