Weighted drill pipe is a kind of medium weight drilling tool similar to drill pipe, its wall is thicker than drill pipe and thinner than drill collar. It is usually added between the drill pipe and the drill collar to prevent the sudden change of the cross section of the drill pipe, reduce the fatigue of the drill pipe, and replace part of the drill collar with it, which can reduce the torque and lift the load in deep wells, and increase the drilling capacity. In directional wells, it can be used to drill at high speed with low torque, reducing the wear and breakage of the drill pipe. Because they are less rigid than drill collars, they have a smaller contact area with the wall and are less prone to differential pressure jamming. The weighted drill pipe produced by Trina complies with SY/T5146, API Spec7-1 and NS-1 standards. In order to reduce the wear of casing and weighted drill pipe, wear-resistant strips can be welded at the end of joints and the middle thickening of weighted drill pipe, and our company has obtained the production and use licences of ARNCO 100XT, ARNCO 150XT, ARNCO 300XT, ARNCO 350XT authorised by American Anchor Company.
