Regarding heat exchangers that have been stored in a warehouse for several years, how is the service life calculated?
Thread Content
One of the heat exchangers supplied by the vendor was designed and manufactured 7 years ago, and it is now to be delivered for use in a project. Should the useful life of this heat exchanger be calculated based on its date of manufacture or on the date it began to be used? What else should be noted in such cases? Replacement of old and new standards, corrosion testing, etc.?
Measure the corresponding wall thickness and check the strength; if the inspection records from that time, such as non-destructive testing and heat treatment data, are still available, they can be provided. No need to redo it; the supervision team approves issuing a new report
The service life of a heat exchanger should be calculated from the time it is put into use, rather than from the time of its manufacture. Even if a device is not used for a long time, its storage environment and its impact on the materials must be taken into consideration. The following points should be noted: 1. Check whether the storage environment meets the supplier’s requirements, to avoid damage to the components or a decline in their performance due to excessive humidity or temperature levels. 2. Conduct corrosion and damage inspections to ensure that all components are still in good condition, with no significant rust or damage. 3. Verify that the product design complies with the specifications and standards of the current project, especially by checking whether any new regulations or standards have been implemented since its manufacture. 4. If the design and materials of the heat exchanger are based on old standards, it may be necessary to upgrade it or replace certain components to meet new standards and performance requirements. It is recommended to carry out comprehensive maintenance and testing before installation to ensure the performance and safety of the equipment. .
