Processing technology of seamless drill pipe
InactiveCN111571123AExtend the service lifeReduce scrap rateDrilling rodsDrilling casingsScrapProcess engineering
The invention relates to a processing technology of a seamless drill pipe, and relates to the technical field of seamless pipes. The technical problem is that the final revealed mechanical propertiesof the seamless drill pipes are different, resulting in relatively high scrap rate and relatively low service life of some batches of seamless drill pipes. The processing technology includes the following steps of: (S1), raw materials: putting pig iron into a furnace and adding alloy components and refining agents for refining to obtain billets; (S2), perforation: carrying out perforation treatment after heating the billets to obtain tube blanks; (S3), cold rolling: carrying out cold-rolling treatment on the tube blanks; (S4), cutting: carrying out fixed-length cutting on semi-finished drill pipes; (S5), chamfering: chamfering the semi-finished drill pipes; (S6), surface treatment: carrying out basic surface treatment on the drill pipes; (S7), strengthening layer: coating the surface of each finished seamless drill pipe with a strengthening layer; and (S8), packaging: carrying out batch packaging on the produced seamless drill pipes. The invention has the effects of increasing the service life of seamless drill pipes and reducing the scrap rate during use. The processing technology provided by the invention has the effects of prolonging the service life of the seamless drill pipe and reducing the scrap rate during use.
