摘要
An integral remanufacturing process of discarded oil pipe, including steps of: preprocessing, including picking out the discarded pipe with wall of 2.8 mm thickness or above, detaching the coupling, checking the Magnetic flux leakage, cutting the thread, eliminating oil and stain, straightening, blasting, and sorting according to different length; lining with ceramic, wherein in the centrifugal machine spinning with high speed, the melted iron liquid via selfpropagating reaction is filled into the ditches and corrosion pits of the inner wall to combine with the inner wall of the oil pipe, and is integrated with the transition iron layer under the ceramic layer, and machining thread including machining thread at the end of the pipe by using numerically controlled lathe and precision comb knife, applying thread compound, and attaching the coupling.
