Meaning of flange shield

Valve insulation is a common insulation measure in industry, and valve insulation cover is of great significance to industrial production. For example, if the valve on the heat pipe is not well insulated, it can leak during multiple switching processes due to uneven thermal expansion and cold contraction.

With the rapid development of industrialization and the continuous progress of science and technology, the use of mechanical equipment and pipeline facilities is more and more extensive. However, these equipment and pipelines in the long-term use of the process, will suffer varying degrees of damage or wear, which will not only affect the normal production and use, but also have a serious impact on the service life of equipment and pipelines.

In major factories, flanges are the most common kind of parts, mainly in the connection between pipes and pipes. There are holes on the flange, mainly used to wear the bolt, there are gaskets between the flanges, and the two flanges are connected together through the nut. In this process, the flange gasket causes a backlog, so that it fills the uneven place on the surface of the flange, so as to play the role of sealing so that the liquid in the pipeline does not leak out.

Flange protective cover is generally used for flanges and valves of chemical and dangerous media, and plays a role in protecting flanges and valves. So, what are the specific functions of the flange protective sleeve?
