Technical Specifications
Our Core Drilling Rods are available in lengths ranging from 3 meters to 4 meters, catering to diverse drilling requirements. We offer multiple types including HQ, NQ, BQ, and PQ to suit different applications. Manufactured using ISMT, Jindal Gold, or ONGC-grade pipes, the rods ensure high strength and durability. Induction hardening enhances hardness levels up to 35–40 HRC for ISMT pipes. Each rod is precision finished to maintain straightness, proper alignment, and reliable performance.
Manufacturing Process
The manufacturing of our Core Drilling Rods follows a strict quality-controlled process. It begins with precision cutting of pipes as per required length. Adaptors are attached using friction welding to ensure strong joints. The rods then undergo stress relieving at high temperatures to remove internal defects. Induction hardening is applied to improve hardness and durability, followed by oil tempering for toughness. Final steps include reinforcement welding, straightening, and thorough inspection before delivery.
