Plate heat exchanger plates are corroded again? Mastering these points allows you to reduce losses

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, regardless of the amount, and do not check whether the distribution is uniform, so that the guide plate further corrodes, but the expected effect is met.
