ESEN METAL – CATHODIC PROTECTION – SACRIFICIAL ANODES

ABOUT US

ESEN METAL - ALUMINIUM ANODES

Aluminium Anodes is used in Cathodic Protection of iron and steel constructions that are located in places with Cl ion and sea water, resistivity under 1000 Ohm.cm

Generally the usage field is as follows:

• Hull of ships and ballast tanks

• Harbour and ports

• Platform, buoy and vs.

• Pipe lines under the sea

• Unrefined Petroleum Storage Tanks ( Dual Anodes )

Aluminium Anodes's are preferred in long term Cathodic Protection projects because of their current capacity and high efficiency.

Aluminium Anodes's, produced by ESEN METAL, are casted from primer aluminum ingots with 99,8% purity, are analysed chemically and electrochemically according to the international standards
