Scope

GB/T 41343-2022 is the English-translated version of 石油天然气工业钛合金钻杆.

GB/T 41343-2022 is the Chinese standard "Petroleum and natural gas industries—Titanium alloy drill pipe". Its scope clause reads: This document specifies friction welding of pipe body and butt-welded drill pipe joints with thickened ends for use in oil and gas drilling and production operations.

Technical delivery conditions, manufacturing process, material requirements, inspection and test procedures, and marking, packaging, storage and Save and so on.

This document applies to the manufacture and inspection of friction-welded all-titanium alloy drill pipes. The titanium alloy drill pipe in this document is divided into three grades.

TD95, TD105 and TD120 according to the nominal yield strength of the pipe body. This document does not deal with the physical properties and evaluation methods of titanium alloy drill pipes.

Note. Refer to GB/T 22512.2 for the detailed requirements for thread processing of drill pipe joints.
