Tube and tube heat exchangers are commonly used heat exchange equipment in the industrial field, and their maintenance is very important for the long-term and stable operation of the equipment. The following are the main maintenance requirements for this equipment:

       1, Regular inspection: Regular inspection is requiredTube and tube heat exchangerCheck the shell, head, pipe side, tube sheet, inlet and outlet pipes and other joints to check for abnormal noise, corrosion and leakage. At the same time, check whether the bolts of each connecting piece are complete and secure, and whether the instruments and safety devices meet the requirements.

       2. Cleaning and maintenance: Due to long-term operation, dirt may accumulate inside the equipment, resulting in reduced heat exchange efficiency. Therefore, regular cleaning is required to keep the inside of the equipment and the environment clean. When cleaning, appropriate cleaning agents and tools should be used to avoid damage to the equipment.

       3, Pressure and temperature control: During operation, the inlet and outlet temperature, pressure and flow rate need to be strictly controlled to prevent sudden changes. At the same time, the wall thickness of the equipment needs to be measured regularly to ensure its pressure-bearing capacity.

       4. Insulation layer protection: Check the insulation layer of equipment pipe accessories and keep the insulation layer intact to reduce energy loss and improve heat exchange efficiency.

       5. Operating specifications: Operators should strictly abide by safe operating procedures and conduct regular inspections of equipment to ensure normal operating parameters of the equipment.

       To sum up, the maintenance requirements of tube and tube heat exchangers involve many aspects, and regular inspection, cleaning, maintenance and other work are required to ensure the normal operation of the equipment and extend its service life.
