If there are leaks in the air cooler, they can be sealed up. What is the typical design margin for air coolers? The design margin varies depending on the level of understanding of the operating conditions; generally, 15-20% is taken into account. Besides mass, what other factors can cause leaks in air coolers? Main reasons for leaks in air coolers: 1) Quality issues with the heat exchange tubes ； 2) Uneven welding stress in each pipe section ； 3) Poor or defective weld or expansion joint quality ； 4) Dust corrosion ； 5) Oxidative corrosion due to frequent shutdown of the heat exchange tubes ； 6) Change in material fatigue properties due to hot-cold cycling of heat exchange tubes ； 7) Corrosion of the heat exchange tubes is caused by an lack of understanding of the operating parameters.
