Double wall drill pipe for reverse circulation
Product Description:
The double-wall drill pipe is a full-hole drilling tool, and the hole wall gap is small, so there is no space condition for the broken rock to collapse, and the double-wall drill pipe has a certain supporting effect on the hole wall. The continuity of the drilling process avoids the damage to the drilling caused by the pressure excitation and suction caused by the frequent lifting and lowering of the drilling tool.
