With over a decade of experience specializing in rotary drilling rig manufacturing, we are a leading international supplier of piling equipment. We produce standard Kelly bars, interlocking Kelly bars, and friction Kelly bars, compatible with various rotary drilling rigs including BAUER, SANY, XCMG, ZOOMLION, SOILMEC, MAIT, and IMT. Our products range from 2 to 5 telescopic sections, with drilling depths from 15 to 150 meters and torques from 120 to 480 kN·m. High-strength, wear-resistant steel structures combined with precision machining ensure stable torque and drill pressure transmission for efficient construction. Interlocking Kelly bars are suitable for hard rock and high-pressure conditions, providing powerful locking output; friction Kelly bars are better suited for deep-hole operations in medium-hard formations, offering smooth operation and higher construction efficiency.

Core Barrels are used for cutting an annular ring in rock or concrete (also reinforced concrete).The centre core is usually broken with chisel, rock auger or cross-cutter, The advantage of acore barrel is the concentration of the crowd force and torque on a small ring of cutting teeth. Thediameter series of HM core barrels are standard sizes, Other lengths and diameters can besupplied on request.
casing
casing
The casing system includes: double-wall drilling casing, single-wall drilling casing, casing fittings, casing shoes, and drive adapters. Main applications: Heavy-duty casing is required for high-power rotary drives or vibrators. Two types of casing are available: double-wall casing and single-wall casing. Double-wall casing is versatile and designed to transmit the high rotational and vertical forces generated by the drilling rig's rotary drive or vibrator. Using double-wall casing ensures a smooth drill string. Single-wall casing is suitable for applications with stringent weight requirements.

Pipes are typically used after the reinforcing cage is in place to pour concrete into bored piles, preventing the concrete piles from cracking or developing gaps. Our pipes are manufactured from high-quality drawn steel plates to ensure high strength.Pipe sections can be connected in two ways: threaded connections and wire rope connections. Threaded pipes are equipped with threaded male and female couplings, while the wire rope connection system facilitates quick assembly/disassembly of pipe sections during concrete pouring. O-rings are used between the male and female couplings to prevent water and slurry ingress.
