Apparatus for Measuring Corrosion Rate inside a Fluid Transport Pipe

摘要

The present invention relates to an apparatus for measuring a degree of corrosion inside a fluid conduit. The present invention relates to the apparatus for measuring a degree of corrosion for measuring a degree of progress of corrosion caused by various types of corrosion substances in crude oil moving on a sea floor such as a submarine pipeline, and a corrosion coupon constituting the apparatus for measuring a degree of corrosion. By measuring the apparatus for measuring a degree of corrosion including the corrosion coupon in a part of a fluid conduit, flow of the moving crude oil is prevented and an existing method is improved. Besides, corrosion which may occur between the corrosion coupons constituting the apparatus for measuring degree of corrosion and the fluid conduit is prevented. The present invention also relates to a technique for preventing corrosion of the outer surface (side and bottom surfaces) excluding the measurement surface (inner surface) of the corrosion coupon constituting the apparatus for measuring a degree of corrosion.
