油氣輸送用無縫鋼管首批檢驗問題探討

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

摘要: 分析了目前無縫鋼管首批檢驗中存在的問題：首批檢驗規(guī)范無統(tǒng)一標準；小批量訂單的首批檢驗難以進行；按照鋼級進行首批檢驗的方式不完全適用；反復對工藝成熟產(chǎn)品進行首批檢驗意義不大；生產(chǎn)單位缺乏對首批檢驗數(shù)據(jù)的保存等。對無縫鋼管首批檢驗規(guī)范的制定提出了合理化建議。

Abstract: 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.
