Beijing superior Drilling Equipment Co., Ltd is a comprehensive enterprise set PDC bits, tricone bits production sales. The company was founded in 1989, covers an area of 27 acres, is located in the vast expanse of Hebei Plain, is located in the central area of the major oil fields, unique geographical location, has a strong design, development and production capacity.
The main structure features:
The Rock Reamer with replaceable cutter was developed for large diameter HDD projects where extended life downhole is critical. The larger bearing and cutters dramatically extend the downhole life over smaller, conventional-style cutters.
The replaceable cutter sets are available in both TCI and Milled Tooth styles to fit for all sorts of rock formation. All bit's bodies have three-six cutters and can open four different hole sizes.
All cutters bearing is metal sealed. Cutters lock is used for preventing cutter failing off.
400-2000mm hole opener are available.
Replaceable hob-type rock reamer for large-scale non-excavation rig for large diameter trenchless pipe laying construction, suitable for a variety of rock strata, reaming diameter range of φ450-2200mm.
Hob roller body cold-rolled large diameter carbide, broken rock effect is good; Bearing diameter, impact resistance; Metal seal, long life, generally more than 150 hours or more.
The body is made of high quality alloy steel with good weldability. After modulation treatment, the tensile strength is high, which can meet the requirement of large tonnage drilling rig.
Wheel body and the body connection is reliable, easy disassembly, do not need large dedicated hydraulic equipment, artificial wrench can be convenient to replace the wheel body.
