PRODUCT DETAILS
Heat-treated wireline drill rods and drill pipes with precision CNC machining — international-level accuracy and mechanical performance.
Overview
Our wireline drill rods are made from high-strength, high-toughness special geological steel pipes, machined on high-precision CNC lathes with formed cutting tools. Threads are inspected with special thread gauges, and the thread sections receive special strengthening treatment. Concentricity and straightness stay consistent, so accuracy and mechanical performance reach international advanced levels. Both ends are heat-treated. Non-standard rods can be made to order.
