Service life of fixed pressure vessel

The service life of fixed pressure vessels is a problem involving multiple factors, and the specific age may vary depending on factors such as design specifications, materials, manufacturing processes, and use environments. Generally speaking, the design service life of fixed pressure vessels is usually about 20 years, but this value is not absolute, and it needs to be judged according to the actual situation.

First of all, the fixed pressure vessel refers to the pressure vessel installed in a fixed position and in a static state all the year round. According to different uses and design requirements, fixed pressure vessels can be divided into storage tanks, reaction furnaces, heat exchangers and other different types. These devices play an important role in industrial production, but their service life is limited.

In the design stage, the service life of the pressure vessel will be considered according to the expected service conditions, material properties, corrosion allowance and other factors. Therefore, different pressure vessels may have different design life.

However, it is worth noting that the design service life is not equivalent to the actual service life. In the actual use of the process, the operating conditions of the pressure vessel, maintenance, use of the environment and other factors may have an impact on its service life. Therefore, even if the pressure vessel has not reached the design service life, if serious defects or safety hazards are found during use, it may need to be scrapped in advance.

In addition, for pressure vessels that have reached the design service life, if they still need to be used, regular inspection and safety assessment must be carried out in accordance with relevant regulations. After passing the inspection by the professional organization, the use registration certificate can be changed and continued to be used. This process is designed to ensure that the safety performance of the pressure vessel meets the requirements and ensures the safety of personnel and the environment.

In summary, the service life of a fixed pressure vessel is a complex issue that needs to be judged based on specific conditions. In all aspects of design, manufacture, use and maintenance, operations should be carried out in strict accordance with relevant specifications and standards to ensure the safety performance and service life of pressure vessels.
