Cathodic Protection Calc

Anode & Corrosion Sizing

$4.99 · Designed for iPad. Not verified for macOS.

Cathodic protection current and anode calc. How many anodes does your pipeline or tank actually need? Stop over-designing cathodic protection systems with spreadsheet guesswork. Cathodic Protection Calc sizes your sacrificial anode system in seconds using real engineering inputs. Enter surface area, coating efficiency, current density, anode type, and design life. Get total protection current, required anode weight, number of anodes, and spacing — all calculated to industry standards. WHAT IT CALCULATES: - Total protection current (mA and Amps) - Bare surface area from coating efficiency - Required total anode weight for design life - Number of anodes based on typical anode size - Anode spacing across the structure STRUCTURE TYPES: - Buried pipeline - Storage tank bottom - Marine structure - Wharf and dock pilings ANODE TYPES SUPPORTED: - Zinc — standard for marine and soil - Magnesium — higher driving voltage for soil - Aluminum — lightweight marine applications - Each with capacity (Ah/lb) and utilization factor INPUTS: - Surface area (sq ft) - Coating efficiency (%) - Current density (mA/sq ft) - Anode type selection - Design life (years) Built for corrosion engineers, pipeline operators, and CP technicians. Works completely offline — no internet required.
