Tubular coolerCleaning:

1. Physical Cleaning Methods: Fixed tube sheet types can be cleaned with a pump brush, while for pull-out type or floating head types, the tube bundle can be removed for cleaning. 2. Chemical Cleaning: When scale changes from loose to dense and hard, mechanical cleaning methods are no longer effective. At this point, acid washing is recommended. Hydrochloric acid can easily dissolve calcium carbonate and magnesium carbonate scale without preheating, so the acid wash solution is typically a room temperature hydrochloric acid solution. Although acid washing can effectively loosen scale and restore the normal state of the cooler surface, hydrochloric acid is corrosive to copper tubes. To protect the cooler wall from erosion by hydrochloric acid, an additive must be added to the acid wash solution, which is a substance that significantly delays the metal dissolution process. The additive we use isPhthalimido-triazoleThe BC-801 water stabilizer is used at a concentration of approximately 3%. According to experience, if mechanical cleaning is performed on time, acid washing can be carried out once every 2a-3a; otherwise, it is necessary to perform acid washing once a year.

1. Tube-in-tube coolers use bare tubes (unfinned) for heat transfer, featuring a high external film heat transfer coefficient and strong anti-pollution capability.

2. Tube-type coolers utilize purple copper tubes, which are machined into finned heat dissipating plates, resulting in a compact product with a large heat exchange area.

3. Spiral baffles on the tube-type cooler facilitate a continuous and uniform spiral flow of the cooled liquid, overcoming the heat exchange efficiency limitations caused by the baffles in a cross-flow design.

4. Tube-in-tube coolers feature expanded tube ends, overcoming the adverse changes caused by high-temperature welding of materials.

5. The tube-type cooler features excellent structural performance, stable sealing, high heat transfer efficiency, compact structure, and small footprint.
