Drive Drilling Flushing Heads
Drive drilling flushing heads allow for the introduction of flushing media into the drive drilling string. Flushing heads are selected to match the shank on the hydraulic drifter as well as the casing diameter and casing thread being utilized.
Drive drilling flushing heads for alternate casing sizes and hydraulic drifter shanks are available upon request.
Components used in and with the Drive Drilling Flushing head include the following.
The flushing body has a female thread to match with the hydraulic drifter shank and a male thread to match the casing in use.
Flushing ring and seals
The flushing ring is held stationary by the mounting bracket fixed to the drifter while the flushing body rotates. The flushing ring is the connection point for the flushing hose and has upper and lower lip seals to contain the flushing media.
The mounting bracket, which is matched to the hydraulic drifter, keeps the flushing ring stationary on the flushing body.
