ABSTRACT:
An anode for the internal protection of hollow corrodible magnetically receptive metallic substrates is attached to a flexible permanent magnet along its length, thereby enabling it to hold to the substrate. This prevents abrasion and electrical short-circuiting of the anode when turbulent flow would cause an unattached anode to abrasively contact the substrate. A method of inserting the anode into a substrate, such as a pipe, is also described.
