TECHNICAL FIELD

[0002] Electrolytic polishing pipe (EP pipe) is a metal pipe processed by electrolytic polishing process, which makes the surface micro convex preferentially dissolved through electrochemical dissolution, so as to obtain ultra-high smoothness (Ra as low as 0.02-0.1 μm), pure surface (remove oxide layer and impurities) and enhanced corrosion resistance (form uniform passivation film), and at the same time has excellent fluid performance. The electrolytic production device refers to a complete set of equipment for realizing material preparation, purification, surface treatment and other industrial production processes through electrolytic principle (i.e. using direct current to drive electrolyte solution or molten electrolyte to occur oxidation-reduction reaction).

However, in the electrolysis process, if the multiple pipe fittings are in contact with each other, a low-resistance conduction path will be formed at the contact point, resulting in abnormal local current distribution (sudden increase of current density at the contact point and insufficient current in the surrounding area), which causes excessive dissolution of the pipe fitting contact part to form recesses, pinholes and other defects, and insufficient dissolution of the surrounding area to leave convexities, resulting in increased surface roughness, contact marks and corrosion streaks, and mutual contact of the pipe fittings will destroy the uniformity of the electric field, resulting in obvious differences in polishing degree of the same batch of pipe fittings and decreased overall processing consistency and other adverse conditions.
