1800mm flue cutter type sand reamer

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 mandrel is made of alloy material that meets the API petroleum standard. The through-shaft through-type design ensures that it will not break due to excessive torque. The body of the reamer is made of high-quality steel. The surface is welded with wear-resistant tape after strict heat treatment to effectively enhance the drill bit Impact resistance And wear resistance. The cutting teeth can be selected from ordinary alloy heads and alloy picks. The alloy heads are suitable for hard soil or viscous clay, soft mudstone and other formations with low cost and fast hole expansion speed; alloy picks are suitable for mudstone and soft sandstone. When drilling, according to different formation hardness, it can adjust and replace picks of different quality.
