Regarding the maintenance of single head pipes

2016-07-04Foshan Feiyue

Although single headed tubes are a type of electric heater, they are used for a long time in electric heating equipment, so the maintenance of single headed tubes should not be underestimated. If the single head pipe is not maintained for a long time, if there is a problem with the single head pipe during heating, the small one is that the single head pipe is damaged and the machine is damaged, and in serious cases, it can be dangerous.
The repair and treatment of blackening of single ended pipes is often the most common maintenance method, which we refer to as blackening treatment. After blackening treatment, a layer of oxide film will form on the surface of the heating tube, providing good protection for the heating tube. How to perform blackening treatment on heating tubes?
The blackening treatment of single headed pipes generally involves several simple steps:
1. The prerequisite for blackening treatment is to keep the surface of the heating tube clean and tidy. If there are impurities on its surface, it will not be conducive to blackening treatment.
2. The first thing to do is to clear the organic matter on the surface, which is called degreasing treatment. Everyone should rest assured that degreasing treatment is easy to achieve here. Defatting treatment only requires the presence of degreasing solution. And degreasing solution is also easily available on the market. The requirement for degreasing treatment is to maintain an extremely high alkalinity of the liquid, with a stable pH value of around 13. The time requirement is approximately 30 minutes. After this treatment, the surface should be cleaned to remove impurities generated by chemical reactions. Cleaning must be done with clean water to ensure a high level of cleanliness on the surface of the heating tube.
3. After alkaline washing, it needs to be pickled. Because its surface not only contains alkaline organic matter, but also acidic organic matter. So acidic cleaning is also necessary. A pH value of 3 is required for acidity, and the processing time should not exceed about 10 minutes.
4. After completing the above three steps, it is necessary to ensure that the Ph is between 2-4. A time of 10 minutes is sufficient. After processing, proceed with cleaning.
5. Dry the single headed tube. Drying is done to remove the water adhering to the surface of the heating tube. Finally, it's time to apply oil.
