PIPE PROTECTION TAPES AND WRAPPING MACHINES: Full Range on the Market

IN Great Britain the heaviest corrosion of buried pipelines occurs in neutral waterlogged clay soils, which lie in belts across the country. This type of corrosion—not fully appreciated for some time because conditions are generally neutral and anaerobic—is now considered to be caused by the activities of sulphate‐reducing bacteria. These organisms are prevalent in sulphate‐bearing clays, and are able to perform the normal functions of oxygen in removing hydrogen from the cathodic elements of the electrochemical systems on metal surfaces.
