Treated by quenching and tempering heat treatment, these core barrels deliver outstanding anti‑crush and torsion resistance, well‑suited for fractured rock formations and deep‑hole coring operations.

Available wall thickness options: 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 7mm, 8mm, 10mm. Standard outer diameters: 43mm, 59mm, 73mm, 89mm, 108mm, 127mm, 146mm, 168mm, 194mm, 219mm, 245mm, 273mm, 325mm. Non‑standard OD and single‑piece length can be customized per client drawings and field requirements.

Custom thread connections are available to fit most common drilling rigs , ensuring tight thread joint, quick assembly & disassembly and less on‑site wear‑and‑tear. Our core barrels serve geological exploration sampling, mining rock coring, water well drilling, geotechnical investigation and pre‑piling exploration projects. We provide bulk supply for global drilling contractors, equipment importers and engineering firms, and support technical selection guidance for different ground conditions.
