The drill pipe joint is an important connecting part of the oil drill pipe and drilling tool, and is widely used in the oil drilling industry. Our pup joint drilling is finished with high-quality and unique materials for excellent durability and precise dimensional accuracy. The threads on the fittings are cut on a CNC machine, which ensures high precision of the threads and prolongs the service life of the fittings. Considering the specificity in practical applications, we use phosphate coating or copper plating to enhance the wear and chemical resistance of the joint. This pup joint drilling has good mechanical strength and comprehensive performance and meets international standards, it can be widely used in oil, natural gas, sewage treatment and other industries.
