How to outline the steps for heat exchanger maintenance and the quality control points
The same goes for heat exchangers: first, determine the type of heat exchanger by examining its structure – whether it has a fixed tube sheet or a floating head, or if it’s of the U-tube type. For those that require core removal, core removal should be carried out; for those that don’t, it isn’t necessary. Quality control points involve the key aspects and requirements at each stage, such as the sequence in which bolts are removed and tightened, as well as the torque requirements for tightening them. This is just a preliminary discussion; I welcome feedback from those with more experience.
How to outline the steps involved in the maintenance of heat exchangers and the key quality control points. There are various types of heat exchangers, which are classified according to their specific maintenance requirements. The main tasks in maintaining heat exchangers include the following: 1. Identifying leakage points and sealing them; however, if too many leaks are present and this affects the heat exchange efficiency, the heat exchanger must be discarded； 2. Inspect and clean scale and deposits ； 3. Heat exchangers with sealing materials should also be replaced. Describe the sequence of maintenance tasks in accordance with the disassembly steps. The key point of control is ensuring successful leak testing, including at the leak-sealing points and static sealing points.
