All our wireline drill rods are heat treated. Our drill pipes will also be suited to drill holes. They are very popular in china. Our wireline drill rods are made according to strict DCDMA standards. They provide a tight mechanical seal for better performance. To provide you with more options, wireline drill rods with RO threads are now available. These rods feature excellent durability and quality craftsmanship. Advantages of Drill Rod Thread * The most common threaded connection; is increased maximum drilling depth due to the thread tooth profile, which assures the high resistance to the tensile, compressive, and bending loads; * Easy make-up and break-out; * Load effectiveness of the threaded connection provides sufficient durability under standard drilling conditions; * Thread heat treatment at high-accuracy CNC machines, surface treatment of the thread and near-tool-joint thread area allow to meet the world rod analogs in terms of all characteristics.
