The MMO Canister Anode is a premium, long-lasting cathodic protection solution engineered specifically for demanding environments like high-resistivity soil. This complete, pre-packaged unit combines a high-performance Mixed Metal Oxide (MMO) Tubular Anode inside a durable galvanized steel canister filled with conductive coke breeze.
Designed for both vertical deep well and horizontal installation, it provides centralized, uniform current distribution to protect large-scale or complex underground structures, including pipelines, tank bottoms, and well casings.
Core Construction & Design
Active Anode Core
Material: Hollow Titanium Tube (ASTM B338 Grade 1 or 2)
Standard Dimensions: ≥1 inch diameter / ≥40 inches length
Coating: Proprietary Iridium-based Mixed Metal Oxide (MMO)
Function: Precisely sized to meet required current capacity and design life.
Robust Canister
Material: Spiral-wound galvanized steel (0.6mm wall thickness)
Standard Dimensions: ≥3 inches diameter / ≥60 inches length
Function: Provides mechanical strength and optimal groundbed contact.
Complete Unit Weight
Total: ≥9 kg (anode, backfill, and canister combined)
Function: Ensures sufficient mass and density for stable installation and effective performance.
Conductive Backfill
Material: Premium coke breeze, pre-packed
Function: Creates a large, conductive interface with surrounding soil, reducing groundbed resistance and ensuring optimal current output.
Key Features & Advantages
Long Service Life & Stable Output
Delivers a consistent current output of up to 5 Amperes for 20 years or more when used with carbonaceous backfill. This guarantees long-term protection and significantly reduces lifecycle costs.
Superior Current Discharge
The synergy between the high-efficiency MMO anode and the coke breeze backfill enables excellent current discharge across a wide range of soil resistivities, making it ideal for challenging geographies.
Reliable Cable Assembly
Comes factory-fitted with a 20ft (6m) long, 8 AWG cable featuring HMWPE/Kynar insulation. The critical anode-to-cable connection is hermetically sealed with a proprietary, high-integrity, waterproof epoxy molding to prevent the primary failure point and ensure long-term reliability.
Installation Flexibility
Can be installed vertically in deep wells or horizontally, adapting to specific site requirements and space constraints. Custom sizes are available upon request.
Applications
This MMO canister anode is ideal for the cathodic protection of:
Underground Storage Tanks (USTs)
Above-Ground Storage Tank Bottoms
Buried Pipelines and Networks
Complex Plant Structures
Deep Well Casings
Critical Installation Note
⚠️ Important: Never lift or manipulate the anode by its cable. Always handle the canister itself to prevent stress on the critical cable-to-anode connection. The internal connection is highly reliable but not field-serviceable.
