There is more than one reason for stainless steel heat exchange tubes to be eroded, and there are many factors that may cause their erosion. The following are three common reasons summarized by the data.
Under partial load conditions, the superheated steam cooling section plan is particularly tight. Blindly increasing the extra heat transfer area will cool the superheated steam entering the heater below the saturated temperature, resulting in condensed water in the superheated steam cooling section, forming a high-speed flow The vapor-liquid two-phase flow of the gas will cause erosion to the heat exchange tube.
Heat exchange tubes in shell side heaters are subject to erosion by wet vapor and vaporized hydrophobic attack. Although a reasonable internal arrangement and an anti-scour baffle at the entrance can prevent the heat exchange tubes from being eroded under normal working conditions, the problem is not so simple in other occasions (such as partial load operation).
The high-pressure heater tube is a tool that is often used when using stainless steel heat exchange tubes, but sometimes the high-pressure heater tube will leak and cause the stainless steel heat exchange tubes to be eroded.
