high efficiency spiral drill rod
The high-efficiency spiral drill rod can meet the practical needs for water and gas exploring and injection under the coal mine.
The high-efficiency spiral drill rod can meet the practical needs for water and gas exploring and injection under the coal mine. It adopts square coupling for rod's connection, easy assemble and disassemble. It's tension resistance can be up to 1323.89 Mpa by using special steel material, smithing and heat treatment.
Matching our drilling machines with spiral dry drilling technology, it can keep high drilling speed and drilling efficiency. Compareed with traditional drilling technology, it can avoid torsion and bend stress efficiency and improve the drilling speed.
In addition, it has large advantages in coal digging which adopting serried hole drill and gas discharging. And it can discharge gas and overcome the stress at high speed to achieve the our burst proof and ensure the coal digging safety.
Bore hole diameter: 42, 45, 60, 69, 76 (mm)
Coupling size: 13*13, 18*18, 24*24 (mm)
