Steel-cased steel directly buried steam insulation pipe is also called insulation steel pipe for steam pipeline. And has strong corrosion resistance, the service life can reach 50 years. Its thermal insulation performance can reduce the heat loss by 70%, avoiding the heat loss in the process of steam transportation. Why is it called directly buried steam insulation pipe? That is, the steam pipeline is manufactured in the factory, and it only needs to be transported to the construction site and directly welded and buried in the ground. This design reduces the workload of the construction site, improves the installation efficiency, and guarantees the quality of the project, which can be said to serve multiple purposes.

There are two types of thermal insulation steel pipes used for thermal insulation pipes, one is polyurethane thermal insulation pipes for transporting hot water, and the other is steel jacketed steel thermal insulation pipes for transporting steam. The structure of the polyurethane insulation pipe is relatively simple, while the structure of the steel jacketed steel directly buried steam insulation pipe is more complicated. We take the simple outer sliding of the steam pipe as an illustration. From the inside to the outside are the working steel pipe, the outer anti-corrosion layer of the working steel pipe, the sliding bracket, the rock wool or glass wool insulation layer, the reflective layer, the air insulation layer, and the outer protective pipe. , Outer steel pipe anti-corrosion layer.

The steel-cased steel direct-buried steam insulation pipe has been continuously updated, and strives to be used in more environments. For example, the advent of nano-aerogel has solved the transportation of steam with a temperature resistance of 1200 degrees Celsius. It is believed that the size of the steel jacketed steel directly buried steam insulation pipe can be updated in the near future.
