Yes, the cryogenic piping standard has requirements for the service life of the pipe. The specific age requirement may vary depending on factors such as different pipe types, materials, working pressures, working environments, etc. In general, the design and use of cryogenic pipes should take into account their long-term stability and safety, including factors such as material aging, corrosion, fatigue, etc. Therefore, relevant standards and specifications need to be followed during the design, manufacture, installation and use of pipelines to ensure that they can meet the predetermined service life and ensure their safety and reliability during use.
At the same time, in order to ensure the normal operation of cryogenic pipes and prolong their service life, regular maintenance and inspection are also required. This includes checking the tightness, integrity, anti-corrosion performance of the pipeline, etc., and timely identifying and dealing with potential problems to prevent accidents.
It is important to note that the specific service life requirements of pipelines may vary depending on different standards and specifications. Therefore, in practical applications, specific pipeline standards and specifications should be referred to to understand and follow the relevant service life requirements.
What standards and specifications specify the service life of cryogenic pipes?
Regarding the service life of cryogenic pipes, there are indeed some standards and specifications that stipulate it. However, it is important to note that specific standards and specifications may vary depending on the region, industry, and specific use case.
In China, there are a series of national standards and industry standards for the design, manufacture, installation, use and inspection of pressure pipelines. These standards usually contain requirements for the material, design, manufacture, and installation of the pipeline, as well as the service life or life assessment method of the pipeline. For example, standards such as GB/T 20801 “Code for Pressure Pipelines – Industrial Pipelines” may stipulate the service life of cryogenic pipelines.
In addition, some international standards and specifications, such as ASME, ISO, etc., may also cover the service life of cryogenic pipes. These standards usually put forward corresponding service life recommendations or requirements based on factors such as the material of the pipe, the working pressure, and the working environment.
However, it is important to note that even if these standards and codes specify the service life of cryogenic pipes, the actual service life will be affected by many other factors, such as the maintenance status of the pipeline, the mode of operation, environmental factors, etc. Therefore, when determining the specific service life of cryogenic pipelines, in addition to referring to standards and specifications, it is also necessary to consider comprehensively in combination with the actual situation.
If you need to know the specific service life requirements of cryogenic pipes, it is recommended to consult the relevant national, industry or international standards, and consult a professional plumbing engineer or relevant institutions for further confirmation and evaluation.
