The implementation standard of steam transmission and insulation pipeline in Bengbu Power Plant started late in our country because of the directly buried heating technology. The above three conditions need to be continuously improved. From the point of view of the quality problems in engineering practice, the problems that should be paid attention to in the design and construction of polyurethane thermal insulation directly buried heating pipe: OK. The size and structure of the pipe for laying the heat-tracing cable is exactly the same as that of the ordinary heat preservation pipe. The outer wall of the special heat-tracing cable scarf steel pipe is laid in parallel with it, and the point heat is used to heat the medium through the steel pipe.
