Reverse Circulation Drill Rods 4 in OD for reverse circulation well
drilling
Heavy duty RC Drill Rod, 4 inches
This product can be used in the following Reverse Circulation
systems:
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 hardfacing program without fear of
embitterment. We use a microalloy midsection (midbody), ST52V,
90KS1 MIL VLD possessing a superior abrasion resistance.
Our inner tube midsection (midbody) 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.
