- 摘要:
- SY4056－93是我国石油天然气行业标准中第一部油气管道射线探伤标准，它包括探伤工艺和质量验收两方面内容，总结了我国30多年来油气管道探伤经验，参考了API－1104等国际油气管道探伤标准，并结合我国油气管道安全运行和施工装备的技术条件，可使质量评定达到恰如其分，体现标准在技术经济方面的价值。本文就验收中的缺陷评定问题展开探讨。
The Standard SY4056 - 93 is our country's first standard on the radiographic inspection of oil and gas pipelines. It includes two main contents: inspection technology and quality reception. It summa thes the experiences ovcr 30 years in the inspection of oil and gas pipelines in oor country. By referring international standarrds, such as API - 1104, and by combining the safe operation and technical condi tions on construction equipments of the oil and gas pipelines in our country, the quallty may be precise ly assessed, and in result great technical and economical efficiencies may be gained. This paper inquires into the aseessment of the imperfections in this standard.1995,1(1): 12-15 收稿日期：1999-8-8分类号：TE973.6
