Plate for plate heat exchanger is corroded again? Mastering these points allows you to reduce losses

In the application of heat exchangers, many users have such confusion --- why are the heat exchanger plates corroded again?

Corrosion of heat exchanger plates not only consumes maintenance and repair costs, but also consumes time and manual installation; mastering these points can effectively help you reduce plate corrosion.

1. Pay attention to the misunderstanding of material selection

Some people think that stainless steel is a universally corrosive material, even titanium. Some factories habitually use stainless steel to solve the corrosion caused by any problem, but the result is often poor and waste; each material has unique advantages, such as

Nickel stainless steel is much superior to carbon steel in terms of resistance to the atmosphere, so "universal materials" must be cautious, and finding out the "cause" and prescribing the "symptom" is the key.

2. Changes in details should be considered

Attention should also be paid to changes in details of the equipment during operation. If the original equipment is operating normally, corrosion has suddenly appeared, but the process has not changed, and the raw materials have changed and the media content is different, which will cause corrosion.

Three, anti-corrosion measures should be appropriate

The method of anti-corrosion should be appropriate, not just use it. Some factories use corrosion inhibitors to prevent corrosion, no matter how much they are used, they do not check whether the distribution is uniform, so that the guide plate will further corrode, but the expected effect is met.
