Rock reamer 1100mm

The cone has a reasonable tilt Angle, and the palm back is inset with reinforced alloy to prevent premature wear of the palm back. It has the cone anti-peeling technology to prevent the bearing damage to the maximum extent and the accident in the hole caused by the falling off of the rear wheel body. The front end of the bit body is equipped with a guide block and guide ring, which has a good guide and slag discharge effect. Select the most suitable tooth shape according to different strata to improve the construction efficiency For large reaming, the weight reduction design is adopted to effectively reduce the weight, reduce the tendency of pipeline track to change line, reduce the resistance of reaming and hosting. Specially developed for trenchless engineering, reasonable tooth distribution and extra reinforced alloy on the palm back can effectively prolong the service life of the reamer in complex strata

  • Description

  • 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

    Reamer size(inch)  9”- 78”
    Center pipe diamater 90-230 mm 
    Thread connection  Pin*box (IF,REG , NC,FH )
    Application Horizontal direction Drilling rock reaming, such as medium strata with high compressive strength, such as hard shale, limestone, sandstone, dolomite, etc
