HDD 34inch Rock Reamer Roller Cone Horizontal Directional Drilling Equipment for No-dig Project
Rock reamer
Horizontal Directional Drilling hole openers are also known as HDD reamers which used to enlarge the pilot hole in Horizontal Directional Drilling (HDD). HDD is used in trenching and excavating is not practical. This drilling technology allows for a steerable trench-less way to underground.
Three stages of the process:
Choose the suitable type rollers according to your formation condition:
| IADC | Rock formation | WOB (KN/mm) | PRM(r/min) |
|---|---|---|---|
| 417/427/437 | Low compressive strength, high drill-ability and extremely soft formation, like shale, clay, sandstone, conglomerate etc | 0.35~0.90 | 140~70 |
| 447 | Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, plaster etc. | 0.35~1.00 | 140~60 |
| 517 | Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, etc | 0.35~1.05 | 120~50 |
| 527 | Soft formation with low compressive, like shale, clay, sandstone, soft limestone, salt rock, anhydrite etc. | 0.35~1.05 | 120~50 |
| 537/547 | Low compressive strength, medium hard formation with hard abrasive interlayer, like Hard shale, anhydrite, soft limestone, sandstone, dolomite with mezzanine, etc. | 0.50~1.05 | 110~40 |
| 617/627/637 | High compressive strength, medium hard and thick hard interlayer, like hard shale, limestone, sandstone, dolomite, etc. | 0.50~1.05 | 80~40 |
