Integral (integrated) pier rough drill pipe, drill pipe joint and drill pipe body are integrated structure, no friction weld, divided into drill pipe inner and outer thickening process. By referring to the structure of the oil drill pipe, the original drill pipe joint and the drill pipe body are connected to the improved integral thickening structure by welding, which eliminates the problem that the performance of the original weld area is difficult to guarantee, and improves the overall performance of the drill pipe. In order to improve the overall strength of the drill pipe, the drill pipe is treated with overall tempering, and the joint is phosphated. The overall fatigue strength and shear strength were significantly improved.
