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
