It is not necessary to consider the connection and sealing of the inner and outer pipes, and a strict monolithic structure is formed, and the energy saving effect of the pipeline is also the most superior. The pre-built direct-buried insulation pipe is a kind of “tube-in-tube†technology, which integrates various insulation materials with the inner and outer pipes to form a pipe insulation and insulation material with higher insulation performance and higher mechanical performance. Then, the insulation layer of the pre-buried insulation pipe has a variety of materials such as glass wool, rock wool board, polyurethane, etc., then which kind of insulation material is used more excellently and the application is more ideal?
