Applied to drill complex rock formations
Drills at any angle
Good straightness of borehole
Maximum depth of borehole is 150Meters
Teamwhole concentric casing drilling systems
Usually the land surface of the earth is covered with loose, unconsolidated material such as soil, clay,
silt, sand, gravel and boulders, which varies in depth from a few centimeters to hundreds of meters.
Use concentric system can drill this complex formation very well.
The systems are available through the whole product range the smallest being for 114 mm (4 1/2") casing and
largest size available at the moment is for 1220 mm (48") casing.
Application Range
Applied to over burden formations with complex topographic and geological conditions,such
as gravel,fissured formation,boulder,landfill of construction refuse etc.
Drill at any angle
good straightness of borehole
Maximum depth of borehole can reach 150 meters
