Steam, how to pressurize the pipeline if the pressure is not enough?

When steaming steam, the pressurization method of insufficient pipeline pressure is: using centrifugal compressor to increase steam pressure.

Steam pipes are different from hot water and cold water insulation pipes. If it is not handled properly in construction and production, there will be a certain explosion danger. Although the structural design and pipe-making technology of steel insulated pipe with steel casing have considered the problems of condensed water, pipeline waterproofing, corrosion leakage and so on.

Some insulation pipe manufacturers have adopted waterproof caps such as heating shrink sleeves at both ends of the pipe or sealed them with materials with good ductility and sealing performance. However, due to many factors such as construction conditions (including regional conditions and meteorological conditions) and construction management, it is difficult to ensure that the insulation layer is always in a dry state.

Extended data:

The introduction of steam pipeline is as follows:

Once the insulation layer of steam pipeline is immersed in water, it will not only have a great impact on the temperature drop and energy loss of the conveying medium, but also cause the shutdown or maintenance of the pipeline conveying system, resulting in huge economic losses. When put into operation, moisture and moisture are baked by the steam in the pipeline and become steam. Condensed water is formed at the interface between organic insulation layer and inorganic insulation layer or between external protection layer and organic insulation layer, which affects the insulation effect.

In severe cases, due to the action of steam pressure, steam will penetrate the insulation layer, which will increase its temperature and pressure, and eventually lead to the rupture of the insulation structure and the phenomenon of "shooting", which is harmful to human body.
