Thermal power plant steel pipe with insulation layer

Steel sleeve insulation composite steel pipe is one of the pipes buried directly underground. It can be buried without the concrete structure, the steel pipe thermal expansion will be proceeded in the outside pipes, thus can lower the cost of the raw material, shorten the construction date and ensure the safety of the heating pipes. This kind of pipes can be used widely in various temperature environment, especially suitable for high temperature steam pipeline project. The operating temperature can be 150℃-450℃。
