4''-101.6mm RC Dual Wall Drill Rod With 4'' Remet Thread For RC Drilling
Product Introduce: Reverse Circulation RC Drilling Rods is also called Double wall drill pipe, double drill pipe or Dual Wall drill pipe. It consists of two layers of inner and outer drill pipes (called inner pipe and outer pipe). The inner and outer pipes constitute an annular gap, which is a channel for pumping the flushing medium to the bottom of the hole when hydraulic rock drilling and center sampling drilling. The central hole of the inner tube is fixed as a whole by discharging the flushing medium, and each double-walled drill pipe is connected with the screw of the outer tube to ensure transmission of torque and pressure. The inner tube is usually connected by a plug-in method, which generally only serves as a flushing medium. Therefore, a sealing device is required at the plug-in place.

Adavantages: 1.Heavy duty tool joints and superior manufacturing technique promise to make RC drill pipe the industry standard. 2.Inner tubes slide into place and seal with double o-rings as the threaded outer tubes are torqued together. 3.Abrasion-resistant alloy steel inner and outer tubes extend life of the drill pipe Working Principle: Reverse circulation is achieved by blowing air down the annulus of the rod, the differential pressure creating air lift of the water and cuttings up the inner tube which is inside each rod. It reaches the deflector box at the top of the drill string then moves through a sample hose which is attached to the top of the cyclone. The drill cuttings travel around the inside of the cyclone until they fall through an opening at the bottom and are collected in a sample bag. For any drill hole there will be a large number of sample bags, each one marked to record the location and drilling depth that the sample was obtained. The collected series of sample bag cuttings are later taken for analysis to determine the mineral composition of the drill hole. The analysis results of each individual bag represents the mineral composition at a particular sample point in the drill hole. Geologists can then survey the drilled ground analysis and make decisions about the value of the overall mineral deposit. Detailed Photo:
About us: SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
Delivery Way: By Air, By express or By Sea
