XPS foam insulation pipes are widely used in chemical pipeline insulation engineering, petroleum, chemical, centralized heating networks, liquid and gas transportation networks, municipal engineering, etc. High temperature prefabricated direct buried insulation pipe is a type of direct buried prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. The insulation pipe is composed of steel pipe/polyethylene sheath/jacket skin/pipe skin/polyurethane foam layer. It has the characteristics of high strength, strong toughness, smooth surface, strong compressive strength, uniform wall thickness, high tensile strength, and no pipe bursting. It is an ideal equipment for manufacturers of thermal insulation composite pipelines to produce polyethylene sheaths/jacket skins/pipe skins.
