Mmo Anode Tubular for ICCP Groundbeds, Marine Piles and Tank Floors: Lightweight Titanium with Customized Sizes

Buried pipelines, marine piles, and tank floors all rely on impressed current cathodic protection (ICCP). For those jobs, Mmo Anode Tubular from Shaanxi Chuanghui Daye Metal Material Co., Ltd. starts with a titanium tube substrate (ASTM B338 Grade 1 or 2). On top sits a mixed metal oxide coating, either Iridium-Tantalum (Ir-Ta) or Ruthenium-Iridium (Ru-Ir). Inside the system it works as the main discharge element. Cast iron anodes are heavy by comparison, this one is up to 90% lighter. Sizes get customized. Sample testing is available too. Send your working conditions before ordering, so the coating and dimensions can be matched to the project.

What Is an MMO Tubular Titanium Anode?

Inside ICCP systems, an MMO tubular titanium anode does the job of an auxiliary anode. A titanium tube forms the substrate, usually ASTM B338 Grade 1 or 2. The electrocatalytic layer is mostly Iridium Oxide (IrO2) plus Tantalum Pentoxide (Ta2O5).

Graphite and silicon-iron anodes weigh a lot. They crack easily. They also burn off faster. Shipping and handling This product takes less effort because it is lighter. Consumption rate stays low, measured in milligrams per ampere-year, so designs of 20 to 50 years hold up. High-chloride environments do not change its dimensions either.

Specifications

Certification

Center Connection Design

On This product, the cable meets the anode at the middle of the tube. Current then leaves the anode evenly. That cancels the end effect, the early wear that shows up where the cable joins. The connection sits sealed inside the tube. Mechanical knocks and electrolyte cannot get to it there.

Light weight pays off on site too. Freight is simpler to handle. During installation the cable takes less strain. In deep well groundbeds, that makes a cable-to-anode connection failure less likely.

Coating Selection for Soil, Freshwater and Seawater

Match the coating to the electrolyte. Oxygen evolution is what Ir-Ta systems are built for, so soil and freshwater suit them. Chlorine evolution is what Ru-Ir / Ru-Ti systems are built for, so they suit seawater. Choose the wrong coating for the environment and it can fail fast. Tell us your environment before you order, and we will match the formulation to your Mmo Anode Tubular order.

What you start with counts as well. Purity and ductility are both higher in Grade 1 titanium. That can make a difference at sintering time, when the oxide coating forms: fewer cracks.

Applications

Deep well groundbeds for oil and gas pipelines. Some soils carry high resistance. City sites get crowded, so there is little room on the surface. The answer is to go straight down. Strings of tubular anodes sit vertically as far as 100 m deep, packed in coke breeze backfill, and they keep transmission pipelines protected.

Marine jetties and offshore platforms. Here several tubular anodes get put together into string anodes. Mounting is either on a sled or by suspension. Seawater is full of chlorides, and that is what these strings are built for. Submerged steel pilings stay free of pitting corrosion because of them.

Above-ground storage tank floors. Tubular anodes are placed in horizontal groundbeds under the tank floor to give uniform current distribution. This is important because the groundbed is difficult to reach once the tank is built.

Quality Control and Sample Testing

Coating integrity and electrochemical longevity are the two things quality control watches. What gets checked:

Accelerated life testing: Here the anode runs at a higher current density. The goal is to see whether the coating gives out too soon.
Coating loading and thickness verification: X-Ray Fluorescence (XRF) analysis confirms the distribution of noble metals.
Adhesion testing (bending and tape test): Mechanical stress is applied here. The check confirms the MMO layer still holds onto the titanium.
SEM/EDX morphology analysis: Scanning under the microscope shows how porous the coating is and whether it is even.
Helium leak testing: This one applies to factory-cabled assemblies. It checks the internal moisture seal. It also helps stop crevice corrosion where the connection is made.

A Mill Test Certificate (MTC) is available for the titanium substrate. Tell us which tests and reports your order needs. Sample testing can be arranged too, so ask about it before you commit to a bulk order.

Mmo Anode Tubular Customization and Purchasing Considerations

Every size is made to fit your project. Give us the tube dimensions and the string length. The cable arrangement matters too, and so does how deep you plan to install it. Tell us as well whether the anode sits in soil, freshwater or seawater.

Check these points when you compare quotations:

Substrate grade and MTC availability
Coating type and loading
Connection method and sealing
Expected operating current density
Rectifier ripple voltage, which must stay within coating limits

A well-specified Mmo Anode Tubular matches the coating to the electrolyte and keeps output within rated capacity. These two choices have the most influence on whether the 20 to 50 year design life can be reached.

FAQ

Q: What decides how long an MMO tubular titanium anode will last?

A: Two things matter most, the coating load and the operating current density. Consumption stays low in deep wells, so 20 to 50 year designs hold up. Keep the output inside the rated capacity, 100 A/m² for instance.

Q: Why is Center Connection preferred over end connections?

A: The tube's middle is where the contact point sits. Discharge stays balanced that way. End-effect wear goes away, and the connection gets sealed inside the tube.

Q: Can it be used in both soil and seawater?

A: Yes, but the coating must change. Ir-Ta suits soil and freshwater. Ru-Ir / Ru-Ti suits seawater.

Q: What should I check to confirm the titanium substrate is good?

A: Ask for a Mill Test Certificate (MTC) for ASTM B338 Grade 1 or 2. Purity and ductility are higher in Grade 1.

Q: What is the maximum voltage limit?

A: The limit usually comes from the DC rectifier voltage compliance or the breakdown voltage of the surrounding environment. Keep ripple voltage within limits to prevent coating delamination.

Q: Can I order custom sizes and test samples?

A: Yes. Sizes are made to order. You can test a sample too.
