油气输送用无缝钢管首批检验问题探讨

Discussion on First-lot Inspection of Seamless Steel Pipes for Oil/Gas Transmission Service

分析了目前无缝钢管首批检验中存在的问题:首批检验规范无统一标准;小批量订单的首批检验难以进行;按照钢级进行首批检验的方式不完全适用;反复对工艺成熟产品进行首批检验意义不大;生产单位缺乏对首批检验数据的保存等。对无缝钢管首批检验规范的制定提出了合理化建议。

Analyzed are the currently-existing problems concerning the first-lot inspection of seamless steel pipes. The problems include no uniform standard that specifies the regulations for the first-lot inspection, no way to perform the first-lot inspection for small quantity order, lack of full suitability of the steel grade-based method for the first-lot inspection, little meaning of repeated first-lot inspections of proven products, and lack of retaining of data from the first-lot inspection by the production facility. Accordingly, suggestions for establishing regulations for the first-lot inspection of seamless steel pipes are proposed.
