Analysis of Revision and Implementation of Standard GB/T 23802 for Corrosion-resistant Alloy Seamless Tube

摘要: 阐述了耐腐蚀合金无缝管标准GB/T 23802首次修订前后的结构及技术内容的变化。修订后的2015版GB/T 23802将产品规范等级划分为两个，对PSL-2等级产品提出了附加要求；补充完善了无损检测、冲击韧性、缺陷、纯净度、压扁试验、文件、标记等方面的技术要求。结合我国油气田的特点及耐腐蚀合金管材的生产研发现状，提出了对该标准的修订及实施建议。

Abstract: Elaborated here in the paper are the changes of the structure and technical contents of Standard GB/T 23802 for corrosion-resistant alloy seamless tube as made via the first revision thereof. Under the revised standard there are two product specification levels,and for PSL-2 products some additional requirements are specified. And supplement and completion are made for the technical requirements concerning such aspects as NDT,impact toughness,defect,purity,flattening test,documentation and marking,etc. Furthermore according to the country's oil and gas field characteristics and present situation of production and R & D of the corrosion-resistant alloy seamless tube,suggestions associated with revision and implementation of the said standard are put forward.
