service life
The directly buried thermal insulation pipeline can reduce the heat loss in the 0.6-1.2m frozen soil layer by more than 40% compared with the ordinary pipeline, and its service life is 3-5 times longer than other thermal insulation and anti-corrosion materials, and its service life can reach 30-50 years.
Since the polyurethane synthetic material was born in the 1930s, the directly buried thermal insulation pipeline has been developed rapidly as an excellent thermal insulation material, and its application scope has become more and more extensive, especially because of its simple construction and remarkable energy-saving and anti-corrosion effects. It occupies all walks of life.
