Summary:
BS 7361-1:1991 covers the applications of cathodic protection for land and marine functions. This code of practice provides guidance on general principles and information on the cathodic protection systems of particular types of structure for the prevention of the corrosion of buried or immersed metalwork and the internal protection of containers for aqueous liquids. It does not deal with the cathodic protection of off-shore structures, which are covered in Part 2 of BS 7361. The two systems for cathodic protection, sacrificial anodes and impressed current, are described and their characteristics compared. Use of isolating joints at terminal installations (as part of safety precautions at oil terminal jetties, in buried structures, for pipelines and in other situations) are discussed. Secondary structures, current density, current flowing, isolating joints, and reference electrodes are also addressed.
