Pipe-in-pipe process insulation pipe is a type of insulation pipe manufactured by a specific process, and its structure consists of a high-density polyethylene outer sheath, polyurethane rigid foam plastic pipe and steel pipe. This type of pipe is called "pipe-in-pipe" because of its structural characteristics, that is, another layer of pipe is inserted inside the outer sheath to form a double-layer pipe structure.
The main advantages of pipe-in-pipe process insulation pipes include excellent thermal insulation performance, long service life, convenient construction, energy saving and emission reduction. Among them, polyurethane rigid foam plastic pipe, as an insulation layer, has the characteristics of high density, low thermal conductivity and good water resistance, which can effectively reduce the heat loss of the pipeline in the transportation process. The high-density polyethylene outer sheath has excellent corrosion resistance, aging resistance and ultraviolet resistance, which can effectively protect the pipeline from the external environment and improve the service life of the pipeline.
Pipe-in-pipe process insulation pipes are widely used in urban heating pipe network systems, oil transmission pipelines and other fields. In the urban heating pipe network system, the pipe-in-pipe process can effectively reduce heat loss, improve heating efficiency and reduce energy consumption. In the oil transmission pipeline, the pipeline can effectively prevent the internal medium of the pipeline from being corroded and damaged by the external environment, and ensure the safety and stability of oil transportation.
In a word, the pipe-in-pipe process insulation pipeline is an excellent insulation pipeline, which is manufactured by a specific process, with a double-layer pipeline structure, excellent thermal insulation performance and long life, and is widely used in urban heating pipe network systems and oil transmission pipelines and other fields.
