Product Description

Product Description

Dual wall drill pipe/RC drill pipe for reverse circulation drilling

 
Reverse Circulation drilling, or RC drilling, uses rods with inner and outer tubes, the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.
 
The reverse circulation drill rod has four threads which adds to machine operating time. The purpose of the two extra threads is to allow the inner tube to be replaced in the field. It also allows the driller to replace the box tool joint with a new tool joint, without welding and can be done at the site. - We use heat threaded 4130 alloy tool joints; this alloy allows driller to employ a hard facing program without fear of embitterment. We use a micro-alloy midsection (mid-body), ST52V, 90KS1 MIL VLD possessing a superior abrasion resistance. - Our inner tube midsection (mid-body) is a heavy-wall mechanical tube, not a pipe. The inner tube is fixed and won't vibrate under most conditions. The inner tube ends are made from a heat treated alloy and the male end is machine finished after welding for perfect alignment. - The o-ring retainers absorb the percussion forces to eliminate problems arising from the transfer of vibration and torque loads to the outer pipe.
