绳索取芯钻杆用无缝钢管标准的解读

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

介绍了国内绳索取芯钻杆用无缝钢管标准的更新过程,对2009年5月1日开始实施的GB/T9808-2008《钻探用无缝钢管》中的相关技术要求进行了相应解读。根据地质勘探行业对绳索取芯钻杆新的特殊要求,结合国内炼钢技术和制管工艺水平的实际情况,提出了比标准要求更高的个别技术参数指标。

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.
