Mmo Tubular Anode

A MMO tubular anode type of anode that is used in cathodic protection systems for a variety of applications. It is composed of a metal that has been coated with metal oxide (MMO) material, is an electrically conductive material. The MMO coating allows the anode to be used in a wide range of environments and provides superior corrosion protection compared types of anodes. The tubular shape of the anode increases the surface area exposed to the surrounding environment, allowing for increased current output. This makes MMOular anode an ideal choice for corrosion protection applications.

FAQ 

Q:What is an MMO anode?

A:MMO wire anode is a kind of high-tech products, it uses mixed metal oxide coating, titanium core and copper core combination. This crystalline conductive coating can not only activate titanium as anode, but also has super conductivity, which can effectively prevent metal corrosion and oxidation.

Q: What is mixed metal oxide anode?

A:Compared with the traditional anode, the mixed metal oxide based electrocatalytic anode is a new and efficient anode type. The anode has the advantages of stable size and long life, and can not be consumed because of the generation of cathodic protection current. By electrocatalytic anodes based on mixed metal oxides, we can better protect the metal structure, extend service life and improve Factor of safety.

Q:What is the breakdown voltage of a MMO anode?

A:When using MMO anodes, we need to pay attention to the impact of the environment. When we are in the low chloride concentration of fresh water, its breakdown voltage may be greater than 60v, which is a very good performance. However, in high chloride environment, such as seawater, the maximum applied voltage of MMO anode should not exceed 8V.

Q:What is the current density of a MMO anode?

A:For better results in soil and freshwater applications, the recommended current density for the anode should be about 100 amp/m2. In the seawater environment, the current density can reach 600 AMP/M2, which indicates that the anode performance is better in the seawater environment. In addition, this high-intensity discharge will not cause loss to the anode, consumption of less than 1.0 mg/ampere-year, is very durable.

Q:What is the consumption rate of MMO anode?

A:According to the latest data, we know that the consumption rate of MMO anode is very low, only about 1 mg/A.Year

Q:How do you calculate anode weight?

A:In the weight calculation, we need to know the weight of the anode. For a flat anode, we can get the total cubic inch by multiplying the length, height, and depth, and then multiplying the density of the anode to get the weight of the anode. For elliptical anodes, this can be calculated by weight per inch.

Q:How do you calculate anode current?

A:In order to guarantee long term operation over the design life, we need to make a reasonable calculation of the current output of the cathodic protection. Following the Ohm's law equation I = E/R, we can determine the current output of the anode. By analyzing the current demand during the initial, maintenance and final phases of the structure, we can arrive at a current value suitable for cathodic protection. This will effectively prevent problems such as corrosion, wear and tear and deterioration of the structure and ensure that the structure is able to operate stably for its design life.

Q:How do you calculate tubular weight?

A:Weight=(OD-Thk)*Thk*Density*3.14*L/1000000(Unit is mm)

Q:How do you calculate anode?

A:Anode life is calculated based on current, anode weight and anode efficiency. The calculation involves the number of ampere hours produced per pound of anode material consumed.

Q:What size anode do I need?

A:Usually, we all want anodes that perfectly cover the entire height or length of the tank to ensure that the tank is optimally protected. But if you can't find the right brand of anode, don't worry too much. All you need to do is measure the length of the tank and choose the closest anode length. If the anode is too long, don't worry. Simply use a bow saw tool to cut it to the right length.

Q:What is the ratio of anode to cathode capacity?

A:Calculation formula for N/P: N/P = anode area density × active substance ratio × active substance discharge specific capacity / cathode area density × active substance ratio × active substance discharge specific capacity.

Q:Does anode go to positive or negative?

A:In our lives, we often come into contact with a wide variety of appliances and devices. These devices often contain batteries or other DC power sources. This is where we need to learn to distinguish between anodes and cathodes. In a battery or other DC power source, the anode is the negative terminal, which is designed to allow current to flow smoothly. However, in a passive load, the anode is the positive terminal. This is because in a passive load, there is no electromotive force present, and the current can only be limited by one direction, at which point the anode becomes the positive pole of the current.

Positive and negative poles are electrically relative concepts that work together to ensure that the current flows smoothly. In an electron tube, for example, electrons flow from the cathode through the tube to the anode to produce an electrical signal. In contrast, in an electroplating bath, negative ions are deposited on the anode, resulting in the formation of metallic substances such as copper and silver. All of these demonstrate the importance of the anode as a positive electrode.
