A tubular MMO anode uses a coated titanium tube as the active element of an impressed current cathodic protection system. Specify the coating and electrical rating for the installation medium. A bare tube, a tube with attached cable and a packaged anode assembly have different supply scopes.
Provide the structure to be protected, installation medium, resistivity data, current demand, proposed anode locations and target design life. Identify whether the project needs individual tubes, a groundbed string or packaged units. The electrode dimensions and coating are selected within the complete project design, not from soil resistivity alone.
| Procurement item | Requirement to confirm |
|---|---|
| Active tube | Provide diameter, wall thickness, length and active coated dimensions |
| Coating | Confirm MMO formulation and loading for the actual medium and duty |
| Rated duty | Specify current per anode, active surface area and required operating life |
| Lead and connection | State cable type, length, terminal and sealing requirements |
| Mounting and handling | Provide mechanical drawing and installation constraints |
| Acceptance | Agree on dimensional, connection and coating checks and required records |
Specify current per anode in A, current density on an active-area basis such as A/m², or output per active length such as A/m when that is the agreed rating. These are different quantities. A value written in mA/m² cannot be treated as A/m² without conversion, and a per-length rating cannot be compared directly with an area-based rating. Ask for the rating basis, medium, duty cycle and coating specification.
System voltage and current distribution depend on the complete electrical circuit, groundbed or immersion arrangement, connections and operating conditions. Confirm these in the project design. Do not use a generic electrode voltage range as the system voltage requirement.
Define whether the supply consists of the coated tube, the tube with attached lead, or an assembly that also includes a housing and backfill. Installation materials and accessories must be identified separately. This distinction is illustrated in the MATCOR product-form overview; that reference does not establish HYTi product ratings or included accessories.
Does one coating and current rating apply to every environment?
No. Confirm the coating and rating for the stated installation medium, active dimensions and operating duty.
Is a generic service-life figure a guarantee for the project?
No. Agree on the coating loading, rated current, environment, duty cycle and life design basis for the order.
What should be specified for the electrical connection?
Give cable construction and length, current requirement, joint arrangement, sealing requirements and purchaser inspection criteria.
Send the project conditions, required current, target life, drawing, dimensions, coating requirements, cable details, assembly scope, quantity and documents. Contact HYTi to review supply requirements or email jolina@bjhyti.com.

Our solutions are widely used in pipelines, offshore platforms, and underground infrastructure, ensuring reliable protection, reduced maintenance costs, and long-term operational safety.
Choosing the correct tubular anode requires careful evaluation of soil resistivity, design current, installation depth, and service environment. For low-resistivity soils, standard MMO tubular anodes are sufficient, while high-resistivity or marine environments require high-performance coatings such as Ru+Ir coated titanium electrode systems.
Engineers should first calculate total protection current demand based on structure size and corrosion risk level. Then select anode type, ensuring compatibility with backfill materials and installation method. Deep well systems are suitable for long-distance pipelines, while compact tubular designs are ideal for confined industrial zones.
Material selection is also critical. Titanium Grade 1 or Grade 2 is recommended for durability. Coating type determines efficiency and lifespan, with Ru+Ir based MMO coatings offering excellent stability. Designers must also consider operating voltage, expected design life, and maintenance conditions.
HY Ti-Ni Import & Export provides technical consultation to help customers match the right tubular anode system for each project, ensuring cost efficiency, stable performance, and long-term cathodic protection reliability.

1. What is a Tubular anode for cathodic protection? |

What Is Tubular anode for cathodic protection?
A tubular anode for cathodic protection is a cylindrical electrochemical device used in impressed current systems to prevent corrosion of buried or submerged metal structures. It is made from titanium substrate coated with mixed metal oxides, such as Ru+Ir coated titanium electrode, to ensure high conductivity and corrosion resistance. These anodes are installed in soil, seawater, or concrete environments and provide controlled current output to protect pipelines, tanks, and offshore platforms. Their tubular structure allows uniform current distribution, making them ideal for long-term corrosion control in both industrial and marine applications with high reliability and efficiency.
