450mm Rock Reamer Api Fixed Diameter Hdd Hole Opener Rock
The cone has a reasonable angle of inclination, and the back of the
palm is inlaid with a reinforced alloy to prevent premature wear of
the palm of the palm. It has anti-off technology of the cone to
prevent the damage of the bearing to the maximum extent. The ring
has good guiding and slagging effect, and it is cooled in time
during the welding process to prevent the overheating of the cone
from damaging the seal.
Choose the most suitable tooth profile according to different
strata to improve construction efficiency
For large-scale reaming, a weight-reducing design is adopted to
effectively reduce the weight, reduce the tendency of the pipeline
trajectory to change lines, and reduce the blocking card during
reaming and hosting.
The roller blades developed separately for the trenchless project,
the reasonable tooth distribution and the additional reinforced
palm-back alloy effectively increase the service life of the reamer
in complex formations
