MMO-Coated Titanium Strip Anodes for Cathodic Protection and Grounding Systems

What are MMO-Coated Titanium Strip Anodes?

MMO-coated titanium strip anodes are long, flexible strip anodes made of pure titanium, coated with a mixed metal oxide (MMO) layer. This allows the anode to conduct electricity efficiently and operate stably for long periods in harsh environments.

Due to its strip structure, MMO-coated titanium strip anodes can distribute current more evenly than traditional rod or mesh anodes. They are widely used in cathodic protection systems, especially suitable for long-distance structures such as pipelines, storage tanks, and grounding grids.

Why Choose MMO-Coated Titanium Strip Anodes?

Long Service Life

The biggest advantage of MMO-coated titanium strip anodes is their service life. The stable mixed metal oxide coating provides a service life of 20-50 years, depending on operating conditions.

Unlike traditional anodes that dissolve quickly, titanium remains intact during the electrochemical reaction of the coating.

High Efficiency and Low Consumption

The MMO coating exhibits excellent catalytic performance. This means:

Lower power consumption

Stable output current

Higher current efficiency

This makes MMO-coated titanium strip anodes a cost-effective choice in the long run.

Uniform current distribution

Due to its strip shape, this anode can distribute current evenly over a large surface area. Suitable for:

Tank bottoms

Concrete structures

Long pipelines

Better current distribution = better protection.

Applications of MMO-coated titanium strip anodes

Catholic protection of underground pipelines

MMO-coated titanium strip anodes are used to protect buried pipelines.

Steel pipelines are susceptible to corrosion from soil moisture and chemicals. Installing strip anodes on the pipeline creates a protective electric field that prevents corrosion before it occurs.

Application industries:

Oil and gas pipelines

Water supply pipelines

Chemical transportation systems

Tank bottom protection systems

Tanks, especially oil tanks, often experience corrosion at the bottom due to moisture buildup.

MMO-coated titanium strip anodes are installed below the tank bottom (usually in sand or concrete) to form a uniform protective layer.

Advantages:

Full-area coverage

No blind spots

Long-term stable protection

Reinforced concrete structure protection

Concrete structures such as bridges, parking lots, and offshore platforms typically contain reinforcing steel, which rusts over time.

Embedding MMO-coated titanium strip anodes into concrete provides cathodic protection for the internal reinforcing steel.

Applications include:

Bridges
Tunnels
Coastal buildings
Dock structures
Grounding systems and lightning protection

In grounding systems, stable conductivity is crucial.

MMO-coated titanium strip anodes feature:

Low resistance

Long-term stability

Strong environmental adaptability

Widely used in:

Power plants

Substations

Communication towers

Reinforced concrete structure protection

Concrete structures such as bridges, parking lots, and offshore platforms typically contain reinforcing steel, which rusts over time.

Grounding Systems and Lightning Protection

In grounding systems, stable conductivity is crucial.

MMO-coated titanium strip anodes possess the following characteristics:

Low resistance

Long-term stability

Strong environmental adaptability

Widely used in:

Power plants

Substations

Communication towers

Materials and Manufacturing Processes

High-purity titanium substrate

The substrate material is typically Grade 1 or Grade 2 titanium, characterized by:

Excellent corrosion resistance

High strength
Lightweight structure

This ensures that MMO-coated titanium strip anodes can withstand the corrosion of harsh environments such as soil, seawater, and concrete.

Advanced MMO Coating Technology

The coating is composed of a mixture of various metal oxides, such as:

Ruthenium oxide

Iridium oxide

Tantalum oxide

The coating is prepared using a thermal decomposition process, ensuring:

Strong adhesion

Uniform thickness

Long service life

Strict quality control

Each MMO-coated titanium strip anode undergoes the following tests:

Coating thickness test

Current density test

Adhesion test

Life simulation

This guarantees its stable performance in practical applications. Product Specifications and Customization
