Core drilling rod introduction
This drilling rod adopts the new T-shaped steel strip with pre-stress winding, which has the characteristics
of light weight and high elasticity, and is not easy to bend. It has automatic self-aligning function and stable
operation. The drill rod is connected by a spring pin, which is automatically locked and disassembled more
conveniently and quickly. It can be used with hand-held pneumatic drills or reinforced coal drills. It can be
drilled for 8-30 meters, which is especially suitable for high-density water exploration and discharge gas
drilling in mines.
1. It adopts plug-in threaded connection, which is convenient and quick to disassemble, good in sealing,
high in tensile strength and high in pile quality. Good verticality for easy disassembly and installation.
2. This product adopts A3, 4mm thick coiled plate, ribbed joint adopts 35# cast steel piece, and pipe
joint is welded on both sides.
3. This product is tested by water and gas mixed test before leaving the factory.
