1.MMO tubular anode cathodic protection auxiliary φ25×1×1000mm titanium electrode tube

Common specifications and sizes:

Titanium anode tube, also known as tubular anode or noble metal oxide titanium anode tube, is a metal oxide with electrocatalytic activity coated on a tubular titanium substrate. Titanium anode tubes are suitable for many environments, such as soil, fresh water, saline water and sea water, and are currently widely used products in the cathodic protection of shallow buried anodes and deep well anodes in pipeline storage tanks, and they are light in weight, long in service life and cost-effective. .
MMO tubular anode is a kind of auxiliary anode in impressed current cathodic protection system. It forms a cathodic protection system together with potentiostat, test pile, reference electrode, etc.
The mmo tubular anode can be welded and connected to the cable. It can be installed in one, or two or three to form a mmo anode string.

Coating System: Ruthenium/Iridium Metal Mixed Oxides
Application areas:
1. Continuous horizontal ground bed, discontinuous horizontal ground bed, shallow buried vertical ground bed
2. Condensate tank, heat exchanger, water treatment equipment
3. Underground storage tanks, ground storage tanks, water storage tanks
4. Anticorrosion of ships, roads, bridges, building steel bodies, etc.
mmo tubular anode coating type, thickness and anode size can be customized according to the user, which depends on the required current density, the medium environment used and the design life.
There are two main ways to use cathodic protection technology to delay the corrosion of steel structures:
1. Sacrificial anode cathodic protection
Sacrificial anode cathodic protection is to connect or weld metals or alloys with negative potential, such as aluminum, zinc or magnesium, on metal structures. The anode material is continuously consumed, and the released current supplies the protected metal structure to cathodically polarize, thereby achieving protection.
2. Impressed current cathodic protection
The cathodic current is applied to the protected metal by applying a direct current to make it cathodic polarization. In the past, sacrificial anode cathodic protection was generally used for the inner wall of the separator, but the temperature of the inner wall of the separator was high, the composition of the deposited water on the inner wall was complex, and the water quality may be acidic or alkaline. Therefore, the protection period of the sacrificial anode is short, and it is generally consumed in less than half a year. Sacrificial anode protection also exists protection dead angle. On the other hand, the cathodic protection potential of the sacrificial anode cannot be measured, the protection current cannot be adjusted, and the length of the protection period cannot be predicted.
In order to overcome the short service life and uneven protection of the sacrificial anode cathodic protection method, Shaanxi Youchuang Technology cooperated with some companies with strong scientific research strength to develop an impressed current cathodic protection method for the inner wall of the separator.
The number of anodes required is calculated according to the size and area of ​​each chamber, the composition and content of the electrolyte in the sewage, and the required protective current density. The titanium-based tubular mixed metal oxide anode is used as the auxiliary anode to be fixed at the bottom of the separator. A silver/silver chloride reference electrode or a high-purity zinc reference electrode is used on a support at a certain height in the aqueous phase. All cables in the tank are led out through special safety leak-proof joints, and then lead to the corresponding contacts of the potentiostat.
3. Anode (auxiliary) for inner wall anticorrosion cathodic protection
Impressed current cathodic protection using mixed metal oxide tubular anode. Install 3 anodes of 25*700mm in each separator, and install 1-2 anodes in each cavity. The anodes are installed with brackets. The height of the brackets is greater than 300. The original fixing points in the separator are used, but the anode and the separator must be guaranteed. body insulation. The reference electrode is mounted on the tank wall in the same way as the mixed metal oxide anode.
Anode size: generally rod and tube
Current density: 20—500a/sqm
Weldable connecting cables, several to form anode strings.

After years of technical research, HS metal has developed practical flexible anodes, including a filling production line for carbon powder and a crimping production line for cable titanium wire anodes, realizing continuous production.
The basic structure of the flexible anode is: inner anode core material + filling coke powder + outer wrapping fabric + outer mechanically woven protective net, which can be flexibly bent and resembles a thicker cable to become a flexible anode or cable anode.
Advantages of flexible anode products:
Compared with traditional deep well anodes and distributed anodes, flexible anodes have the following advantages:
1. The output voltage is low, so the capacity of the transformer rectifier can be smaller;
2. The cathodic protection potential along the protected object decreases uniformly;
3. The interference to other devices is very small.
4. The protection potential distribution is uniform and the drainage density is large
5. The advantages of long life and high reliability.
Flexible anode products are divided into two categories:
1. Polymer cable (flexible) anode based on nanometer conductive carbon black composite technology
2. Cable (flexible) anode based on MMO/Ti coating technology
These two anodes are buried auxiliary anodes for forced current cathodic protection, which are used to protect underground oil (gas) pipelines, underground storage tanks, chemical containers, etc. from corrosion or to slow down corrosion. It has the characteristics of convenient installation, perfect supporting technology and reasonable price.
