Introduction to Pipe Heater Maintenance

The pipe heater is an important production heating equipment with many excellent technical features: high heating temperature, high efficiency, fast heating and cooling rate, good mechanical properties, etc. As such an important heater, it is essential to do a good job of maintenance and care on a regular basis. So, what kind of inspections do we need to do on the pipe heater on a regular basis? The maintenance methods of the pipe heater are as follows: (1) When maintaining the pipe heater unit, the water side should be cleaned and the air side should be visually inspected. Generally, during operation, if the air temperature is 5°C higher than the normal temperature due to blockage on the water side, it should be cleaned. (2) Cleaning and inspection during pipe heater maintenance ① Remove the flange screws of the circulating water inlet and outlet valves and remove the connecting pipes of the inlet and outlet valves. ② Remove the screws on the joint surface of the front and rear water chambers and remove the front and rear water chambers. ③ Clean the steel pipe. Pay attention to protecting the pipe mouth when cleaning. ④ Clean the rust and mud in the water chamber and rinse it with water. ⑤ Use a scraper to scrape any remaining gasket residue from the water chamber joints and the cooling water inlet and outlet flanges.

⑥ Inspect the air side pipes and radiator fins for damage.

⑦ Inspect the water chamber of the duct heater for cracks and the baffles for glass damage.

⑧ Install the joint gaskets. Use 3-5mm rubber pads.

⑨ Clean the bolts with kerosene and apply black lead oil after they dry.

⑩ Apply red lead anti-rust paint to the inside of the duct heater's water chamber and the inlet and outlet pipe plates. Check that the air cooler tube bundle and its joints with the walls are airtight.
