The rotary jet drill pipe series is the main channel carrier used to transport slurry, compressed air, clean water and other media. In order to meet various rotary jet construction processes, the rotary jet drill pipe adopts Φ 50、 Φ 60、 Φ 73、 Φ 89 geological pipe (origin: Shanghai Baosteel) is used as pipe material, and the joint is made of high-quality alloy steel (northeast special steel) as raw material. The quality of drill pipe is guaranteed through special heat treatment process and advanced double sealing structure. The connection of drill pipe adopts the domestic leading corrugated buckle connection mode, which has the characteristics of convenient connection, good sealing effect and long service life.
