▎ 摘  要

NOVELTY - The pipe has an oil pipe body (1) whose inner wall is formed with a lubricating wearable anticorrosive layer (2). An adhesive layer (3) and a protective layer (4) are formed in the lubricating wearable anticorrosive layer. The lubricating wearable anticorrosive layer whose thickness is for about 100 micrometer. The thickness of the adhesive layer is for about 120 to 260um. The protective layer is provided with graphene. The thickness of the protecting layer is for about 0.5 to 3.7 micrometer. USE - Graphene-lubricating wearable anticorrosion oil pipe. ADVANTAGE - The pipe reduces transport resistance, improves gas well productivity, and reduces corrosion of the inner wall of the oil pipe body so as to reduce cleaning time, thus increasing service life. DETAILED DESCRIPTION - The oil pipe body is formed as a cylindrical-hollow shaped structure. An INDEPENDENT CLAIM is also included for a graphene-lubricating wearable anticorrosion oil pipe manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene-lubricating wearable anticorrosion oil pipe.
