MMO/Ti Flexible Anode | Linear Anode for Pipeline & Tank Cathodic Protection
Our MMO/Ti Flexible Anode (also known as Linear Anode or Flexible Linear Anode) systems represent the ultimate solution for cathodic protection in challenging environments where conventional groundbeds are impractical. This complete packaged system combines advanced MMO technology with optimized carbonaceous backfill, delivering superior performance while significantly reducing installation complexity.
Why choose MMO/Ti Flexible Anode? Unlike first-generation conductive polymer flexible anodes, our MMO/Ti design offers higher current density (up to 900mA/m), longer service life (20+ years), and predictable performance — making it the preferred choice for critical infrastructure projects worldwide.
Optimal Applications
| Application | Key Benefit |
|---|
| Congested Urban Areas | Limited space installations near existing infrastructure |
| Environmentally Sensitive Zones | Minimal environmental disruption during installation |
| Rocky Terrain | Areas where conventional groundbed installation is difficult |
| Complex Pipeline Routes | Protection of pipelines with multiple bends and elevation changes |
| Tank Bottoms | Radial patterns beneath storage tanks, retrofit without excavation |

Frequently Asked Questions
Q: What is the typical design life of MMO/Ti Flexible Anode systems?
A: Our systems are designed for 20+ years service life (up to 50 years in optimal conditions), with the MMO titanium core providing exceptional longevity and the fabric cover designed to withstand soil stresses.
Q: How does MMO/Ti Flexible Anode differ from conductive polymer flexible anode?
A: MMO/Ti anodes offer much higher current density (up to 900mA/m vs 50-150mA/m), longer predictable life, and better performance in high-resistivity environments. They are the preferred choice for critical infrastructure.
Q: Can MMO/Ti Flexible anodes be installed in rocky soil conditions?
A: Yes, the durable woven mesh provides excellent protection against abrasion, and the flexibility allows the anode to conform around obstacles.
Q: What installation methods are recommended?
A: Both trenching and direct plow-in methods are suitable, with specific guidance provided based on soil conditions and project requirements.
Q: Is this anode suitable for tank bottom retrofit without excavation?
A: Yes, the flexible design allows installation through small access points, making it ideal for retrofit applications without tank excavation.
