Diameter 114.3mm 4 1/2'' Metzke Thread RC Drill Rod

1.Inner tubes slide into place and seal with double o-rings as the threaded outer tubes are torqued together.

2.Abrasion-resistant alloy steel inner and outer tubes extend life of the drill pipe

3.Options for additional heat treating of tool joints

4.Options for Urethane Seals to replace traditional "O" Ring setup

High pressure air transported into somewhere of the well along with air pip, via mixer to inject the high-pressure air into the pipe with liquid, due to the density of mixed liquor lower than flushing liquor therefore a differential pressure occurred between pipe and sample tube that to make the mixed air and liquid flow up fleetly by the fluid column pressure and take the rock debris into powder out to the ground from bottom of the hole continuously. By this drilling method will provide with advantages like high penetration rate, quality pore-forming and fewer hole collapse rig drilling in loose formation.

This series reverse circulation pipes can increase penetration in lost-circulation formation, reduce drilling fluid consumption, protect reservoir stratum and save the cost of other consumption tools. In additional, the pipes can be worked in two direction circulation drilling ways to control the well drilling. By reverse circulation method to kill the well the heavy mud can be transferred directly to the bottom of the well, no periodic circulation and save time.
