Design life and service life of pressure vessel

The relevant information on the design life and service life of the pressure vessel can be summarized as follows:

1. design life

the design life of pressure vessels is usually determined according to the expected service conditions and material durability. This age is generally set at the time of design, taking into account factors such as corrosion allowance. According to publicly released information, the design life of national standards for pressure vessels is generally between 10 and 30 years. However, the actual design life may vary depending on the specific use of the container, working conditions, material selection and many other factors.

2. service life

the service life of the pressure vessel refers to the period during which the vessel can operate safely during actual use. This period is affected by many factors, including the design quality of the container, manufacturing quality, use environment, maintenance and so on. Generally speaking, the service life of the pressure vessel should not exceed its design life.

However, it is worth noting that even within the design life, if the pressure vessel has severe corrosion, wear or other damage, it may need to be scrapped in advance. Therefore, regular inspection and maintenance of pressure vessels is essential.

In addition, for pressure vessels that exceed the design age, if they are still safe and reliable after being tested and confirmed by professional institutions, they may continue to be used after being approved by the competent authority. However, the use in this case needs to be more cautious and regular inspection and monitoring should be strengthened.

In general, the design life and service life of pressure vessels are important indicators to ensure their safe operation. When using pressure vessels, relevant safety regulations and operating procedures must be strictly observed to ensure the safety of personnel and equipment.
