Embodiment

[0060] Such as figure 1 As shown, the easy-to-use pipeline stress assessment method for practical engineering problems includes the following steps: ( figure 1 The upper part of the dotted line is the preliminary calculation preparation process, and the lower part of the dotted line is the actual engineering calculation process)

[0061] step one

[0062] First determine the norms that will be used in the assessment, including all planned normsll. The division of requirements for pipeline design grades in various codes is obtained, and the calculation requirements for nuclear grade pipelines are divided into grades 1, 2 and 3.ii.

[0063] step two

[0064] Find out the version of each specification that will be considered in the implementation, usually a chronological version, also code mm, and identify any special requirements nn in the specification or otherwise. Then sort out the load list of all codes to be adopted, and classify it, classify the same load types in all ...

Abstract

The invention relates to an application method of industrial pipeline mechanics computational analysis, in particular to an easy-to-use pipeline stress evaluation method aiming at engineering practical problems. The application method of industrial pipeline mechanics computational analysis starts with load type during actual analytical calculation, then takes various conditions in completing calculation into consideration, and at last acquires required calculation results; and accordingly a new analytical requirement definition method completing the whole pipe stress calculation process is designed. The method can lower professional requirements on program application workers, reduces the error possibility during program using, and further improves efficiency and quality of pipeline mechanics calculation works.

Description

technical field [0001] The invention relates to an application method for calculation and analysis of industrial pipeline mechanics, in particular to an easy-to-use pipeline stress assessment method aimed at practical engineering problems. Background technique [0002] For the mechanical analysis of industrial pipelines, in the past, users of various pipeline mechanics calculation programs in the world have to determine which formula of which version of the code is used to evaluate the various loads of the pipeline calculation problem, which requires the user to be specific about the pipeline problem The mechanics problem and specification are very clear. For example, the conditions that must be distinguished in the design and calculation of pipelines in nuclear power plants include: [0003] 1. The level of the pipeline: nuclear safety level 1, 2, 3, or non-nuclear safety level; [0004] 2. The standard adopted: such as the United States, Germany or France; [0005] 3. V...
