Introducing our Kelly - the dynamic driving force at the heart of the entire drill stem. Available in both square and hexagonal forms, each crafted in strict compliance with API Spec7-1 and SY/T6509-2000 standards, ensuring impeccable quality and performance.
Our Square & Hexagonal Kellys are meticulously engineered using AISI 4145H modified alloy bars, which undergo a rigorous quench and temper heat treatment along their entire length. This process enhances durability, achieving an impressive Brinell hardness value between 285-341. Every detail, from the kelly's end to its drive cross-section and joint, is precision-processed and rigorously tested to meet API specifications.
Boasting state-of-the-art production lines, our facility is equipped with advanced metal processing, heat treatment, and pretreatment equipment, alongside a comprehensive testing system. The entire production cycle, from casting and heat treatment to metalworking, final assembly, and inspection, is meticulously managed in-house, ensuring superior and controllable product quality. With expert engineering support, an efficient sales team, and a competitive pricing edge, we draw customers from all corners of the globe.
