How can the use of non-destructive testing techniques help reduce accidental leaks in heat exchangers?
Thread Content
In the event of an accidental leak during the operation of the heat exchanger, production must be halted; the system needs to be emptied, replaced, and cleaned, after which the heat exchanger equipment is disassembled to locate the source of the leak, the faulty pipes are repaired, and production can resume. This process results in huge economic losses – not only is the normal production order disrupted, leading to reduced output and value due to shutdowns, but there are also increased safety risks during maintenance activities, and environmental pollution becomes inevitable. How can we reduce accidental leaks and ensure the long-term operation of production facilities? We welcome suggestions from everyone.
This is really difficult to control; for example, the quality of the gaskets may be poor, and there can be defects in the sealing surfaces. More importantly, bolts are prone to stress relaxation at high temperatures, resulting in insufficient clamping force.
