Buckle type: inch buckle 4 inch small square buckle
Material: DZ40(ZT380)/DZ50(ZT490)
Length: 1m, 2m, 3m, 4.5m, etc. (length can be customized)
2. Product use:
Geological exploration coring tools are mainly used for surface exploration and coring, high-speed exploration, geological exploration, railway exploration, building foundation exploration, etc. The drilling depth is between 100 meters and 200 meters.
3. Product advantages:
Use DZ40 or DZ50 alloy steel as the main body to increase the wear resistance of the core tube itself

The core pipe is a steel pipe used by the geological department for core drilling. It is a long steel pipe for geological drilling with a hollow section and no joints around it.
A rod in a drilling tool that connects a drill bit and transmits power.
The usual components of the drill string are: drill bit, drill collar, drill pipe, stabilizer, special joint and kelly.
The basic functions of the drill string are: (1) tripping the bit; (2) applying weight on bit; (3) transmitting power; (4) transporting drilling fluid; (5) performing special operations: squeeze cement, deal with downhole accidents, etc.
