◆   Product introduction   ◆

➣The group owns MTI inertia friction welding machine, which has good alignment, ensures the straightness quality of drill pipe / weighted drill pipe, strictly controls the weld loss within + / - 10%, and ensures the accuracy of the final length. Stable welding parameters and welding zone heat treatment ensure the welding performance;

➣The advanced technology of highpower current collecting coil and narrowing the heat affected zone, and the heat treatment process of internal and external cooling at the same time, make the mechanical performance of the friction welding zone uniform and stable, the weld is beautiful, and the service life of the drill pipe is extended;

➣The annual production capacity can reach 3million tons, and the mechanical properties of various series of drill pipes are higher than the requirements of API standards.
