What should be done after the plate and frame air cooler leaks?
Thread Content
Our factory is a northern refinery. Due to the cold weather in winter, the plate and frame air cooler often suffers from biased flow and freezing. How should the air cooler be plugged after the plate and frame air cooler leaks?
Indicate the operating conditions of the equipment and the specific location of the leak. . . . . . . . . . . Easy to solve
This requires considering climate factors when designing the heat exchanger. The inlet and outlet of the heat exchanger need to be properly insulated according to the temperature of the medium to ensure cooling without condensation.
The medium and usage environment need to be considered.
Method 1: If the operating pressure of the heat exchanger is not high (such as 0.1~0.3MPa) and leakage needs to be repaired under operating conditions, it is recommended to use special adhesive to affix metal sheets to repair the leakage. This measure is a temporary leakage repairing measure. Method 2: If the operating pressure of the heat exchanger is high, it is recommended to stop the work and weld to repair the leak. Both method one and method two should involve the heat exchanger manufacturer for maintenance. But the best way to solve this problem is to add a fluid distribution device at the tube side inlet of the air cooler so that the tube side fluid can evenly enter the plate bundle.
