The MATCOR SPL-SandAnode is a patented impressed current linear anode for cathodic protection under above-ground storage tanks where anode-to-tank clearance is less than one foot. Engineered sand backfill replaces coke, preventing electrical shorting between the anode and the tank bottom.
The patented SPL-SandAnode™ is designed for cathodic protection where the anode is installed in close proximity to or in contact with the structure, such as under an above-ground storage tank (AST). The SPL-SandAnode is identical to the SPL-FBR-Anode, with the exception of its engineered sand backfill, which enables installation in close proximity to the structure and prevents the anode from physically shorting to the structure.
The recommended anode system for most above-ground storage tanks (ASTs) is the MATCOR SPL-FBR-Anode in the concentric Tank Ring Anode System configuration. However, when the clearance between the tank bottom and anode is less than 1 foot (32 cm), the SPL-SandAnode is used in the concentric ring configuration or in parallel linear lengths. The MATCOR SPL-SandAnode is the only impressed current linear anode made specifically for under-tank installation in close proximity to metal.
The SPL-SandAnode™ can be designed for any application using the rated current outputs. Because the spacing of the anodes will vary with the application and the distance between the anode and the structure, we recommend contacting MATCOR engineering for assistance with the design.
The SPL-SandAnode is available in any length required. The standard length for one reel is 1,500 feet. Contact MATCOR for assistance with designing or ordering the SPL-SandAnode.
The SPL-SandAnode can be installed by laying it directly on the ground or membrane. The SPL-SandAnode will lay flat without using weights or hold-downs. In some cases it may be installed with a cable plow. For additional information and assistance, contact MATCOR.
