In order to reduce tripping time in the drilling process to improve drilling efficiency, "one elevator one slip" is the general tripping mode. The pipe body within the range of 600mm-900mm under the box end is always injured by using slip and cause "washouts" in pipe body. The slip transverse and longitudinal loads beared by drill pipe are higher and higher along with drilling depth increasing, complicated geological conditions and offshore drilling. Higher slip crushing capability of the pipe body is required. To solve these problems, Hilong designed and manufactured slip-proof drill pipe, the long, thick-walled upset section is designed on the box end.
