to various compressive strenght of the formation. The procduct is
used for zhe reaming of the oil, gas, petrochemical, sewage, power
and fiber optic pipelines in the no-dig horizontal directional

has a good rock breaking effect; the bearing has a large diameter
and strong impact resistance. Using metal seal, long service life.
Advantages
The replaceable hob reamer is forged from high quality alloy steel
with good weldability. After modulation treatment, the tensile
strength is high, which can meet the tensile requirements of
large-tonnage drilling rigs. The wheel body and the body are
reliable in connection and easy to assemble and disassemble, no
large-scale special hydraulic equipment is needed, and a manual
wrench is sufficient, which is convenient for replacing the wheel
body on site.
