Xi’an Jiaotong University; 2. Defense manufacturing is all about 20099 manufacturing and project accounting. This paper focuses on the evaluation methods by levels of the newest edition ASME B31G and compares its advances with the previous two editions.

Through case verification and comparison analysis, the remaining strength of corroded pipes are evaluated by the N31g B31G by four levels, which helps evaluators easily choose different levels of evaluation according to the difficult and easy level of field operation, more and less data, and evaluation accuracy.

A Study on New Edition Assessment Criteria for the Remaining Strength of Corroded Pipeline

Thank you for the help, OKCorall. This document is intended solely for the purpose of providing guidance in the evaluation of metal loss in pressurized pipelines and piping systems. On the other hand, the ASME B31G is not fit for large-diameter and high-strength pipes and needs to be improved in its application range.
