Drilling tools, as one of the most important parts for drilling machine, is necessary for all drilling machines, we hereby introduce the drill rods from Rejee Group to meet different customers’ various needs. And we could also manufacture the drill rods as per customers’ specifications and requests.
High-strength outer planar drill rods
Φ42,Φ50,Φ63.5,Φ73,Φ89; Length 750, 1000, 1500, may also be manufactured to customer specifications and needs.
Outer planar rods feature friction welding technique with full surface welds, providing superior strength in critical areas. It is mainly used for gas drainage borehole drilling operations. It can also be used for mining, hydropower, and geology drilling operation. The drill rod is suitable for conventional and rotary percussion drilling operation as well.
Cable-centered drill rods
This is a high strength rod, providing stable signal transmission. These rods were used in the horizontal directional drilling operation when the national record, with a length of 1212m, was created in August 2011.
Spiral drill rods
Plug-in spiral drill rods
Φ78/50, Φ88/50, Φ90/63.5, Φ100/63.5, Φ110/73, Φ200/89; Length 1000, may also be manufactured to customer specifications and needs. The rods are suitable for gas drainage borehole drilling operations in soft seam borehole drilling operations.
The plug-in spiral drill rods feature phase friction welding technology, with continuous blades, good dusting effect, and easy connection between rods. The rods can do both forward and reverse rotation, facilitating accident management in boreholes.
Thread spiral rods
Φ73/63.5, Φ89/73; Length 750, 1000, 1500, may also be manufactured to customer specifications and needs. The rods are suitable for gas drainage borehole drilling operations in soft seam with medium air pressure.
The wide-blade spiral rods are manufactured for high mechanical strength. The rods can be (un)loaded mechanically, reducing operator fatigue and improving efficiency.\
Wireline coring drill rods
Wireline coring drill rods have a solid mechanical performance with thickened joints. High strength thread satisfies the technical requirements of drilling operations for surface or for tunnel explorations.
Drill rods for petroleum, geology and CBM
Drill rods for petroleum, geology and CBM are manufactured according to API and SY/T5561-2008 standards. The main specifications are 2-7/8’’~5’’. 2-7/8’’~5’’, non-standard drill rods may also be manufactured to customer requests. Medium frequency induction heating is used in rod heat-treatment. Manufacturing parameters of heat treatment are controlled by computer, providing consistently high mechanical performance and homogeneity. The rods can meet requirements in drilling operations for oil, geological and CBM exploration.
