Heat exchanger is an important equipment in the production of enterprises, due to long-term operation, poor quality of circulating water and other reasons, it is easy to make the heat exchanger leakage, affecting the normal operation of the device. The hazard of the leak is manifested as: after the heat exchanger has leaked, the deterioration of the water quality, the turbidity, the suspended matter and the COD value are increased. The metal surface of the heat exchanger tube in the heat exchanger is usually covered by oil film or slime. (ATMPHEDP) is difficult to form a continuous protective film on the metal surface, corrosion inhibition efficiency is difficult to play normally, the heat exchanger corrosion rate increased; for the microbial provides a rich source of nutrients, resulting in a large number of biological slime, Covering the metal surface of the heat exchanger, reducing the cooling effect of the heat exchanger, while causing scale corrosion and microbial corrosion.
Heat exchanger anti-corrosion coating manufacturers suggest that enterprises can do a good job of circulating water system management, as soon as possible to find signs of material leakage, as soon as possible to find out the leak and timely removal from the system is to ensure the quality of circulating water quality is an important means.
Analysis of the causes of heat exchanger leakage:
Device cold exchange equipment leakage, leakage mainly concentrated in the tube bundle, gasket, pot and other parts, causing the heat exchanger leakage mainly in the following factors:
1, the process medium high sulfur content
Heat transfer medium strong corrosive, such as processing of Russian crude oil, hydrogen sulfide content is high, causing the heat exchanger tube bundle side of the media leakage; another water quality of recycled water is poor, causing dirt or microbial corrosion, causing heat exchanger tube bundle Water side leaks.
2, heat exchanger maintenance quality is not stable
Maintenance of poor quality construction, heat exchanger pot is not in place to install, causing heat exchanger leakage.
3, the quality of equipment accessories instability
The gasket is of poor quality and is running for a while, the gasket is damaged, causing the heat exchanger to leak.
4, the production load is unstable
Production device operation is not smooth, the media pressure suddenly increased, but also cause a short period of heat exchanger heaters leakage.
