Installation and maintenance of TPEP anticorrosive steel pipe

 After the polyurethane insulation steel pipe in 1970s, the production and application of the heat preservation pipe was paid great attention abroad, so as to reduce the consumption of power and reduce the environmental pollution and the greenhouse effect. Foreign insulation industry has a long history, and the new thermal insulation materials are also constantly emerging in some developed countries in foreign countries have become a relatively advanced technology. In recent years, China's heating engineering and technical personnel through digestion and absorption of this first? Entering technology is promoting the technology of domestic pipe network construction to a higher level. Over the past few years, the practice has fully proved that the method of creating polyurethane insulation directly buried pipe has many advantages compared with the traditional trench and overhead construction. This is exactly the internal power of the polyurethane insulation directly buried pipe in the heating engineering in China. The high-temperature prefabricated directly buried insulation pipe is mainly composed of four parts. The installation and maintenance of TPEP anticorrosive steel pipe in town, TPEP anticorrosion steel pipe for town and town, installation and maintenance of TPEP anticorrosive steel pipe in town (1): steel pipe, seamless steel pipe and double faced spiral welded steel pipe are selected according to the technical requirements of transporting medium. (2) insulation layer: rigid polyurethane foam. The new insulation scheme is 20mm~30mm aerogel blanket and polyurethane high pressure foaming technology.
