Stainless steel heat exchange tube is eroded!! Why??

Stainless steel heat exchange tube is eroded!! Why?? Heat exchange tube is very familiar to all of us. It is a new kind of building materials. With the increasing application in our survival, tension is widely used in all categories of survival, and is widely welcomed by people. But we can occasionally invent stainless steel heat exchange tube will be eroded in the process of using, which affects our normal survival, so what is the reason why stainless steel heat exchange tube is eroded?

1. The planning of the superheated steam cooling section is particularly tight during departmental load. Blind growth of the extra heat transfer area is enough to cool the superheated steam into the heater to below the saturation temperature, so that it gives rise to condensed water in the superheated steam cooling section, forming high-speed vapor-liquid two-phase flow, and forming erosion of the heat exchange tube. The corrosion resistance of carbon steel pipe is poor, and it is also very sensitive to such erosion.

2. On the shell side, the heat exchange tube of the heater is damaged by the impact of wet vapor and vaporization hydrophobic. As far as the reasonable internal layout is concerned, stainless steel anti-impact baffle is set at the entrance, which can restrain the erosion of the heat exchange tube under normal working conditions, but in other places, such as the department of load operating conditions, the problem is not simple.

3, high pressure heater tube is a kind of thing that we often use when using stainless steel heat exchange tube, but occasionally hou high pressure heater tube will leak, resulting in stainless steel heat exchange tube erosion.

We in the use of stainless steel heat exchange tube time, must do a good job of erosion of the pace, so as to extend its service life, so as to improve the use of building materials, make it play its due utility.
