The importance of checking the heat exchanger

The importance of checking the heat exchanger
Check the heat exchanger is very important. Through the heat exchanger inspection,to determine the actual state of the heat exchanger, to identify degradation and failureof its location, shape, and reasons to take the necessary measures to carry outrepairs to prevent further deterioration of its development, to avoid all non-unitplanned downtime.

Sometimes even if the heat exchanger itself is not severely damaged, also due tosmall leaks caused by heat transfer medium channeling through, resulting in product failure; water coolers leaking pipes, oil or other materials will fleeing into the coolingdevice water system or boiler feed water system, the safety device on all the basicprocess operating conditions and deadly threat; heat exchanger descaling layer if notcleared in time, will also affect the media flow and heat transfer efficiency, the efficiency of heat transfer equipment directly to the deterioration of device reduced ability to increase energy consumption.

In addition, the heat exchanger is usually a pressure vessel, shell and head of itsbearing capacity, the pressure vessel from the point of view of safety requirements, the same should be a high priority. Thus, the heat exchanger for periodic inspection,is imperative.
