Polyurethane foam insulation seamless steel pipe 　　The polyurethane direct buried heat preservation pipe is a direct buried preheating heat preservation pipe with good heat preservation performance, safety and reliability, and low engineering cost. The buried thermal insulation pipe not only has the advanced technology and practical performance that is difficult to compare with the traditional trench and overhead laying pipeline, but also has obvious social and economic benefits, and is also a powerful measure for heating and energy saving. The prefabricated direct buried thermal insulation pipe adopts the direct buried heating pipeline technology, which indicates that the development of China’s heating pipeline […]
