Product Description
Description
Tapered drill pipe is to provide a hexagonal chuck section to provide leverage for the rotation chuck bushing. It usually has a forged collar to maintain the proper shank striking face position in the rock drill, and a tapered drill bit end. Tapered steel lengths are measured from the collar to the bit end. Holes are usually drilled in 0.6 m increments to accommodate the air leg feed length. The drilled steel is extracted and followed with a slightly smaller diameter rock drill bit on the next steel length in the sequence.
The drill pipe is the basic part of the drill string. Its main function is to transmit torque and transport drilling fluid, and to deepen thebore hole continuously by the gradual lengthening of the drill pipe.Therefore, drill pipe occupies a very important position in oil drilling.
Performance
Carburizing process is applied to promote surface hardness, thus grant better wearing quality and life span for the drill rods;
Cost-effective, good performance with reasonable price.
Complete types of drill rod for various drilling scenarios.
Application
For drilling medium-hard to hard and abrasive rock formations, taper angles of 11° and 12° are normally used on modern drill rigs, like Y6, Y10, Y24, YT24 Mobile rock drills pneumatic and hydraulic. For low impact rock drills and softer rock formations, a narrow tape range of 7° is used, such as Indian, Saudi’s granite and marble quarry. A comprehensive range of taper button bits, cross bits and chisel bits with6°, 7°, 11°, 12°, drill hole diameter: 28mm-57mm.
