How is a shell-and-tube heat exchanger disassembled before cleaning?
Shell-and-tube heat exchangers are becoming increasingly useful in our lives. Everyone must have a certain understanding of shell-and-tube heat exchangers. Cleaning a shell-and-tube heat exchanger is quite troublesome, so the disassembly before cleaning is also difficult. The following is an introduction to the disassembly of a shell-and-tube heat exchanger before cleaning, which is related to the introduction.
Please measure first before disassembling. For shell-and-tube heat exchangers, what we are talking about is the compressed length of the tube bundle, which should be recorded in detail in any maintenance procedure of the equipment.
After the measurement is completed, our disassembly work begins. If the gasket is stuck between the plate grooves, a special tool must be used to carefully remove it to prevent damage to the heat exchanger plates and gaskets.
If the gasket of the shell-and-tube heat exchanger is found to be aged, replace the gasket and clean the gasket groove with a ketone organic solvent. Of course, do not forget to evenly apply synthetic resin adhesive in the groove.
Carefully check whether there are holes in the plates of the shell-and-tube heat exchanger. There are many methods to detect this problem.
Check whether there is debris accumulation in the medium inlet and outlet pipes and inlet and outlet channels. If this happens, it indicates that the filter of the shell-and-tube heat exchanger is faulty and needs to be cleaned in time.
When disassembling titanium materials, do not contact open flames; otherwise, oxidation may occur.
Pay attention to check whether there is solid particle accumulation on each plate of the shell-and-tube heat exchanger. If so, it should be handled in time.
Check whether the shell-and-tube heat exchanger is deformed. If yes, please replace it in time.
The above is the introduction to the shell-and-tube heat exchanger equipment, hoping to be helpful to everyone. To ensure the smooth operation of the equipment and extend its service life, daily maintenance work must be done well.
