Polyurethane pre-insulated direct-buried insulation pipe is closely combined with the steel pipe (or PE pipe) for conveying medium, polyurethane rigid foam insulation layer, and high-density polyethylene outer casing. It is mainly used for thermal insulation projects for conveying fluid media. This product is mainly used in urban central heating pipe networks, chemical and petroleum transportation pipelines, water pipelines in extremely cold areas, industrial pipeline engineering in factory areas, and central air conditioning supply and return water. It has characteristics such as efficient insulation, waterproof and anti-corrosion, simple construction, and low heat loss, with a service life of up to 30 years or more.
