Stainless steel RC Rods Metzki Box And Pin Thread With Inner Tubes For Surveying
Product Introduce:
The demand for quality large diameter RC tools is steadily growing.
The water resource industry focuses on extracting ground water for multiple purposes including municipal wells, industrial consumption, and wells for Agri-Irrigation. It is boosted by population growth trends and an increasing number of acres devoted to agriculture.
Environmental considerations continue to increase when drilling water wells in urban areas and has seen a strong trend to the use of RC drilling as it enables effective control of the cutting and drilling fluids. It is essentially a closed loop system that safely contains the cuttings and minimizes potential contamination in environmentally sensitive areas.
Adavantages:
Reliability and long life are built into SOLLROC Reverse Circulation Pipe by using the best materials available. Tool joints are heat treated for optimal strength and wear resistance. Inner tube ends are also heat treated and even chrome plated on the O-ring sealing surface.To make the RC drill pipe good quality.

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.

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
