未焊透长度对在用工业管道安全状况等级的影响

Effect of Incomplete Penetration Length on the Safety Status of Industrial Piping

未焊透缺陷对在用工业管道安全运行影响较大。根据国家现行的在用工业管道定期检验规范,对含有未焊透缺陷的管道进行安全等级划分。得到未焊透长度和安全等级和检验周期的关系,在确保管道安全运行的前提下,尽量延长检验周期,保障企业连续运行。旨在为在用工业管道日常管理和定期检验提供参考。

The impact of Incomplete penetration defects on the safe operation of industrial pipelines isgreat.According to the current state of the country in the use of industrial pipeline regular inspection specification,to contain the defect of the pipeline to carry out safetygrade division.The relationship between the penetration length and the safetygrade and the inspection period is obtained.In the premise of ensuring the safe operation of the pipeline,the test period is extended as far as possible to ensure the continuous operation of the enterprise.The purpose is to provide reference for daily management and periodic inspection of industrial piping.
