Today, let us understand how the leakage of the air heater is generated, and provide help for everyone on how to prevent leakage in use.
1.Leakage at the tube is generally due to the water deposition in the heat pipe or the scale corrosion in the heat pipe. There is no uniform industry standard for the water quality used in air heaters in my country, so the water quality has a great influence on the corrosion of the inner wall of the heat pipe.
2. Corrosion at the joints of the radiating pipes. This is due to the chloride ions in the water corroding the welding points, especially at the turns of the radiating pipes, where the chloride ions accumulate and cause more serious corrosion to the joints.
3. The corrosion of the shell is also the cause of the leakage of the air heater. The shell of the air heater is generally made of steel and aluminum, which has a certain degree of corrosion resistance, but if it is exposed to acid and alkaline substances for a long time, or is in a humid environment for a long time , Since the steel-aluminum connection is prone to electrolytic corrosion, the corrosion is more obvious at the steel-aluminum connection.
Knowing the causes of corrosion of air heaters, we can prevent these corrosions in a targeted manner in daily use, thereby reducing the probability of leakage.
