繩索取芯鉆桿用無縫鋼管標準的解讀

Interpretation of Specification of Seamless Steel Tube for Wire-line Core Drill Pipe

摘要: 介紹了國內(nèi)繩索取芯鉆桿用無縫鋼管標準的更新過程,對2009年5月1日開始實施的GB/T9808-2008《鉆探用無縫鋼管》中的相關(guān)技術(shù)要求進行了相應(yīng)解讀。根據(jù)地質(zhì)勘探行業(yè)對繩索取芯鉆桿新的特殊要求,結(jié)合國內(nèi)煉鋼技術(shù)和制管工藝水平的實際情況,提出了比標準要求更高的個別技術(shù)參數(shù)指標。

Abstract: Introduced in the paper is the renewal of the Chinese specification of seamless steel tube for wire-line core drill pipe, and interpreted is relevant technical requirements specified in Specification GB/T 9808-2008 《Seamless Steel Tubes for Drilling》 as having been effected since May 1, 2009. According to the newly-established special requirements for the wire-line core drill pipe by the geological prospecting industry, and taking actual levels of the domestic steelmaking technology and pipe-making technology, certain technical parameters more stringent than those specified in the applicable specification are proposed.
