REFERENCE ELECTRODE

A reference electrode must have specific electrical, physical and chemical properties. It must facilitate the measurement of accurate pipe/soil/reference electrode potentials on pipelines. It must ideally have a stability that is sustainable for years. For this to occur it should not be polarized by the very low electrical current that will flow in a measurement circuit. The potential should be measured with a high impedance multi-meter or voltmeter.

Reference electrode allows you to measure the potential of the working electrode without passing current through it while counter (auxiliary) electrode allows you to pass current. If oxidation occurs at the working electrode, reduction using the same magnitude of current is sustained at the counter electrode and hence there is no current flow between working and reference electrode(high input impedance) enabling us to follow changes in working electrode potential accurately. This is not possible in a two electrode system although we can get crude values by using certain types of electrodes which can act simultaneously as working and reference electrode.

MMO COATED MESH DISCRETE FOR CATHODIC PROTECTION

clock September 19, 2023 10:05 by author admin

The invention relates to the field of cathodic protection of reinforced concrete structures, and in particular to a design of discrete anode for cathodic protection suitable for being installed inside holes or slits made in the concrete. The anodes commonly used for the cathodic protection of reinforced concrete consist of a titanium substrate coated with transition metal oxides or other types of catalysts for anodic oxygen evolution.

Discrete anodes are not suitable for all applications, especially for thin concrete element or where the reinforcement is randomly spaced within a structure. The main area of application of discrete anodes would be thick reinforced concrete elements, such as beams, head stocks or piles in tidal/ splash zones where the application of ribbon anodes leads to grout acidification in most cases. Having in mind the long term durability of the cathodic protection components installed permanently in concrete and the importance of delivering a CP system with low maintenance.

CP COUPON FOR CATHODIC PROTECTION

clock August 9, 2023 14:10 by author admin

CP coupons and soil corrosion probes (SCPs) can be effective tools in applying CP criteria under challenging operating environments, such as cross-bonded systems or in high resistivity soil environments.

CP coupons are used for measuring polarized ("off") or depolarized (100 mV) potentials on pipelines and other structures, and are useful in situations where these type of potentials cannot be measured easily. This is usually in situations such as cross-bonded systems or structures in fluenced by interference from CP systems not controlled by the main protected system operator, or if it is not practical to simultaneously switch off numerous sources of CP current connected to the pipeline being tested.

SCPs are used to measure the metal corrosion rate, and are connected to the structure so that they receive the same level of CP as the structure. Thus even if the measured potential reading on the structure is not at the minimum required level, the corrosion rate measurement (mils per year, or microns) can be used as an alternative criterion to asses CP effectiveness. Low levels of polarization in high resistivity soils, or erroneous potential readings due to poor soil contact are examples of situations where SCPs can be useful.

MMO COATED TUBULAR STRING & MMO COATED PIGGY BACK FOR CATHODIC PROTECTION

clock July 7, 2023 12:23 by author admin

Cathodic protection is the most common electrochemical technique used to prevent corrosion on pipelines, storage tanks, ship hulls, underground tanks etc. The process occurs when a DC current is passed through an anode and cathode so that the metal becomes cathodic and prevents corrosion.

Cathodic protection is one of the main technique to prevent corrosion. Cathodic protection is of two types they are Impressed Current Cathodic Protection (ICCP) and Galvanic Protection also known as DCCP. Cathodic protection systems protects a wide range of metallic structures in various environments.

Titanium tubular anodes are manufactured using titanium seamless tube and coated with platinum group precious metal mixed oxide coating.

Titanium tubular string for pipelines are arranged in ground beds either distributed or in a deep vertical hole depending on several design and field condition factors including current distribution requirements.

Mixed metal oxide based electro catalytic anodes are a different type of anodes when compared to conventional anodes. These anodes are dimensionally stable, long life anodes that are not consumed during the process of generating cathodic protection current.

Mixed Metal Oxide anodes are typically rated for a given output and life, for example 5 amps at 20 years. Within the normal range of current discharge for MMO anodes, this relationship is linear. The same 5 amp anode rated for 20 years of service would provide 40 years if only operated at 2.5 amps.

MMO piggyback anode is the flexible anode with a long life, which integrates the advantages of large current of MMO anode and excellent conductive performance. Due to its large current and small grounding resistance, it can be buried in the place far away from the anode structure.

MMO COATED PIGGY BACK FOR CATHODIC PROTECTION

MMO piggyback anode is the flexible anode with a long life, which integrates the advantages of large current of MMO anode and excellent conductive performance. Due to its large current and small grounding resistance, it can be buried in the place far away from the anode structure.

Piggy pack anodes are used to protect the tank bottoms. It’s the easiest method of cathodic protection which may not need a weld at site and also easy to handle and install. Piggy pack wire anodes connected with cable by the way of Crimping and sealing with mastic and heat shrink sleeve procedure. The piggy pack anodes are inserted in the jacket with coke fill to sustain the conductivity of the anodes in the place where we install for cathodic protection.

Cathodic Protection is accomplished by applying a direct current to the tank surface of the metal, which causes the electrochemical potential of the structure to shift from a corroding state to a polarized and non-corroding state.

MMO COATED TUBULAR STRING FOR CATHODIC PROTECTION

clock July 6, 2023 09:50 by author admin

We, Ti Anode Fabricators Pvt. Ltd., developed an extremely strong and electrically low resistance centre crimp connection, which ensures the lowest possible electrical resistance (less than 1.0 Milli Ohm) between the cables and anode tube. The Platinum group Mixed Metal Oxide coating is a crystalline electrically conductive coating that activates and enables a titanium substrate to function as an anode. Whether operating in fresh water, seawater, soil, or mud. MMO Coatings are extremely stable even in very low pH environments.

MMO titanium tubular anodes are coated with mixed metal oxide that has an extremely low consumption rate measured in milligrams per year. Unlike other types of anodes the consumption rate of MMO anode is negligible with the dimensions of the anode element remaining virtually unchanged during the operational service life of the anode. As a result, the power required to impress current will remain the same.

Cathodic protection system is a technique used to control a corrosion of a metal surface by making it the cathodic side of an electrochemical cell. Cathodic protection is an old and effective system that prevents forming rust in metal and helps in corrosion resistant. Corrosion  can be prevented by eliminating the oxygen or the positively charged hydrogen ions.

Reference electrodes are generally implemented for the purpose of monitoring the anode in cathodic protection of buried or immersed metallic structures. It is made of high-purity of alloys, ensuring accuracy and stability of potential measurements.

The electrode frame is made of stainless steel, coated carbon steel or Rubber. The electrode can be designed to fix in the structure. By means of specifically designed supports.

These Reference Electrode implements a major usage in the cathodic protection System. Reference Electrode are in different shapes like disc, rod and strip with different dimension, which is also installed in the heat exchanger to monitor the current supply of cantilever anodes.

Cantilever anode is used for protecting pipeline internals, suction and condenser box internal for 30 years and more by applying DC current with transformer rectifier.

Normally titanium is well known for its high resistance to corrosion both water and chemical media but titanium is the poor electricity conductor. So we use platinum/ MMO plating/ coating to increase the conductivity.
