AWWA D106 governs sacrificial anode systems for steel water tank interiors. Here's what the standard requires for anode material, sizing, and placement.

Ask five engineers how many anodes a given pipeline segment needs and you'll sometimes get five different answers, usually because someone started with anode count instead of current demand. Sizing a galvanic system correctly means working the problem in the right order: figure out how much current the structure needs first, then work backward to how many anodes deliver it -- reversing that order is where most oversized or undersized systems come from. Start With Current Dema

At its core, galvanic corrosion occurs when two dissimilar metals come into contact in the presence of an electrolyte, leading to the accele
