Buried pre-insulated pipe is made of carrier pipe (steel/stainless steel/plastic/copper) and polyurethane rigid foam Material (insulation layer), high density polyethylene outer casing (outer sheath).
Because of its low heat loss, good anti-corrosion and insulation performance, fast and safe construction and other advantages, it is widely used in liquid and gas transmission network, central heating network, municipal construction engineering and other fields. It is an important infrastructure and "lifeline" to ensure the safe and efficient operation of the city, and is recognized as an environmental protection and energy-saving product.
