The Copper-copper(II) sulfate electrode
Sulfate Reference Electrode (Cu/CuSo4)
sulfate reference electrodes (CSE) are the most commonly used
reference electrode for measuring potentials of underground
structures and also for those exposed to fresh water. CSE are
not suitable for use off-shore environments or in a chloride
electrolyte as the chloride ions migrate through the porous
plug and contaminate the CSE.
portable type CSE are composed of a copper rod, saturated solution
of copper sulfate and a non-conducting cylinder with a porous
plug at the bottom as shown in above picture.
can supply a wide range of CSE those are intended to use in
soil applications and are made for portable use or for permanent
installations i.e., suitable to use along the pipeline route
or under the above grade storage tanks etc.
chloride (Ag-AgCl) reference electrodes are most commonly used
for testing cathodic protection corrosion control system in
sea water environments. The Ag-AgCl electrode is also used in
concrete structures. There are two types of Ag-AgCl reference
electrodes; in one type the silver electrode is exposed to seawater
and in the other the electrode is immersed in a potassium chloride
(KCl) solution contained in a cylinder with a porous plug.
can supply a wide range of Ag-AgCl reference electrodes those
are intended to use in seawater applications and are made for
portable use or for permanent installations i.e., suitable to
use along the off-shore structures or inside the water storage
Zinc Reference Electrode
is commonly used for onshore and offshore corrosion potential
measurement. Zinc reference electrodes are not stable in carbonates
or at high temperatures. For underground use, the zinc electrode
is packaged in a cotton bag containing the same backfill as
used around zinc anodes. In off-shore zinc electrodes used bare.
can supply all kind of Zinc reference electrodes those are intended
to use for on-shore applications i.e., under the above grade
storage tanks or off-shore in seawater a bare.
Double Insulation Set
Isolating flange kits are required to restrict the cathodic
protection current to the underground portion of the structure
and isolate the buried structure with above ground structure.
Normally isolation gas kits consists off one piece of insulating
gas kit, one full length of insulating sleeve, two insulating
washers and two steel washers for each bolt from both sides
of the flange.
the insulating flange kits following parameters are required;
Outside Diameter of the pipe line
Pressure rating of the pipeline
Type of IF i.e. full face, raised face or only ‘O’
Contents of the product i.e. gas, oil, chemical etc.
supply any kind of electrical insulating kits for any size.
Kindly contact AFIC sales department for further assistance.
Thermite Weld Materials
welding is the process of igniting a mix of high energy materials,
also called thermite, that produce a metallic slag that is poured
between the working pieces of metal to form a join. In the thermite
weld process thermite weld powder ignited at high temperatures
by using flint gun. A violent reaction occurs that produces
through reduction and oxidation a white hot iron slag and vaporous
aluminium oxide. This form of welding is widely used to weld
cathodic protection cables to structure i.e., pipelines, storage
stocks most common type used for cable size 10sq.mm to 16sq.mm.
However bigger or smaller sizes also can supply with appropriate
powder charge sizes along with flint gun to ignite the powder.
is capable to supply most of the items required to complete
the anode groundbeds those are not limited to following;
PVC / Steel casing
support pipes with welded angles
Anode surface markers
Anode lead casing
Anode vent caps with PVC pipes for watering
