What is BS EN 13636 – Cathodic protection about?
BS EN 13636 is a European standard that discusses the cathodic protection of buried metallic tanks and related piping. Cathodic protection is one of the most effective methods for preventing corrosion on a metal surface.
BS EN 13636 specifies the principles for the implementation of a system of cathodic protection against corrosive attacks on buried metal tanks and associated piping. BS EN 13636 specifies conditions and parameters to be met to achieve cathodic protection, as well as rules and procedures for the design, installation, commissioning and maintenance for the protection of buried metal tanks and associated piping.
BS EN 13636 is applicable to the external surfaces of buried metallic tanks and associated buried piping. BS EN 13636 applies to buried tanks and associated piping, even if they are earthed by their local earthing device, which is electrically separated from any general earthing systems and other buried structures. Therefore, tanks that are covered by the present BS EN 13636 include:
- Industrial storage tanks, irrespective of their dimensions and the nature of the stored medium (liquid or gas, flammable or not, toxic or non-toxic, polluting or not)
- Tanks used at petrol stations and on domestic or commercial premises, which contain flammable liquids or gases or polluting substances.
Note: BS EN 13636 does not apply to:
- Above-ground storage tank floors in contact with the ground
- Reinforced concrete containers
- Buried storage tanks that are electrically connected to the whole or a part of an industrial complex
- Buried storage tanks are electrically connected to any general earthing systems.
Who is BS EN 13636 – Cathodic protection for?
BS EN 13636 on cathodic protection applies to:
- Chemical engineers
- Manufacturer of cathodic for metal surface protection
Why should you use BS EN 13636 – Cathodic protection?
Cathodic protection is one of the most effective methods for preventing corrosion on a metal surface. Cathodic protection is commonly used to protect numerous structures against corrosion, such as ships, offshore floaters, subsea equipment, harbours, pipelines, and tanks; basically, all submerged or buried metal structures.
BS EN 13636 provides you with guidance for the installation of cathodic protection systems. Cathodic systems are carried out with the design based on the prerequisites which include the location and installation of test stations and galvanic anodes, impressed current systems and drainage stations.
BS EN 13636 protects the equipment determined by the design, such as isolating joints, coatings, sleeve pipes and local earthing devices, which are integral parts of the structure to be protected and are therefore be installed at the same time as the main structure to be protected.
With BS EN 13636 you can be ensured that the products consistently meet and exceed quality assurance targets.
