Lower Casing Kit
The adjacent illustration shows the installation
of one of the anodes supplied in the “Lower Casing Kit” to a riser pipe. The anode is
specifically designed to fit in a confined area between the bore
casing and the riser pipe and requires only approximately 25mm
What are anodes and
how do they work?
Sacrificial anodes have
been in common usage in a multitude of applications for
many years. They protect all ships at sea and above ground pipelines,boilers, hot water heaters
and generally steel structures immersed in water or damp soil conditions where corrosion could be a problem.
The corrosion (rust) is the result
of electrolytic action travelling through moisture or
fluid to home in on the metal surface at risk. Depending
upon the existing conditions such as amount and quality
of the fluid (water?) and the effective presence of any
other protective coating on the metal surface, the rate
of anode corrosion can vary substantially.
For fresh and groundwater
applications our anodes are of a particular grade of
magnesium which is "electro-negative relative to steel"
which means that they will attract the destructive
electrolytic action on to themselves. This type of galvanic protection is called sacrificial and the
principle of electrolytic corrosion control is called cathodic protection. Because cathodic surfaces
cannot rust,the steel surface is protected.
