Product Description

The drill pipe is a steel pipe with thread on the tail, which is used to connect the surface equipment of the drilling rig with the drilling equipment or bottom hole device located at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit, and together with the drill bit to raise, lower or rotate the bottom hole device. The drill pipe must be able to withstand huge internal and external pressures, twists, bends and vibrations. During the extraction and refining of oil and gas, the drill pipe can be used multiple times. The drill pipe is divided into three types: square drill pipe, drill pipe and weighted drill pipe. The connection sequence is square drill pipe (1 piece) + drill pipe (n pieces, determined by the well depth) + weighted drill pipe (n pieces, determined by the design of the drill tool combination). The classification of drill pipe, drill pipe joints, drill pipe specifications, and steel grade and strength of drill pipe are introduced in detail.
