Product Introduction
MMO tubular titanium anodes use a titanium tube or tubular titanium structure with an active mixed-metal-oxide coating. The tubular form is useful where installation space, active length, electrical connection and current output need to be defined along a narrow cylindrical geometry.
For an actual order, tube diameter, active length, overall length, coating system, working medium and connection method should be confirmed together. Custom tubular configurations can be prepared for new equipment or replacement projects according to drawings or existing-anode details.
Product Parameter

Final coating system, active length and connection design should be confirmed according to the working medium, required current output and installation conditions.
Typical Applications
- ICCP Cathodic Protection
Tubular MMO anodes are used in selected impressed-current cathodic protection systems where a compact anode form and defined current output are required. Installation environment, required output and cable or connection design should be confirmed for each project.
- Water Treatment & Electrolysis
Tubular anodes can be integrated into electrochemical water-treatment or electrolysis equipment when the cylindrical geometry suits the cell layout. Active length, electrode spacing and working medium should be reviewed before selection.
- Electrochlorination Systems
Ru-Ir based tubular MMO anodes may be considered for chloride-containing electrolysis and electrochlorination equipment. Chloride concentration, operating current, temperature and installation geometry should be provided before coating selection.
Product Details
- Tubular Substrate
Tube diameter, wall condition and overall geometry are selected according to the required anode structure. The titanium section used for electrical connection can remain uncoated where required by the design.
- Active Coating Area
The MMO coating is applied to the defined working length of the tubular anode. Active length and coated boundaries should be confirmed from the required output and installation arrangement.
- Connection Structure
Connection rods, tabs, cables or fabricated terminal structures can be prepared according to the equipment interface. The connection area should be clearly separated from the active coated section.
- Replacement Dimensions
For replacement projects, existing anode dimensions, active length, connection position and installation details can be reviewed from drawings, photos or sample information.
Order & Project Support
- Specification Review
Working medium, required current, tubular dimensions and coating direction are reviewed before quotation.
- Installation Review
Active length, overall length and connection position can be checked against equipment layout or customer drawings.
- Replacement Review
Existing tubular anode dimensions and connection details can be reviewed for replacement projects.
- Inspection Coordination
Dimensions, coated area, connection structure and agreed verification items are controlled according to the purchase specification.
FAQ
Q1: What dimensions should be provided for an MMO tubular titanium anode?
A: Please provide the tube diameter, active length, overall length, connection structure and installation dimensions. A drawing or existing-anode reference is especially helpful for replacement projects.
Q2: How is the MMO coating selected for a tubular anode?
A: Coating selection depends on the required electrode reaction, working medium, concentration, temperature and current loading. Ru-Ir and Ir-Ta systems are used for different electrochemical conditions.
Q3: Can the active coated length be customized?
A: Yes. The active section can be defined according to the required working area and equipment layout, while connection and contact areas can remain uncoated where necessary.
Q4: Can you manufacture a replacement for an existing tubular anode?
A: Yes. Existing dimensions, coated length, connection position and installation details can be reviewed from drawings, photographs or sample information before the production specification is confirmed.
