Galvanised steel or iron pipes. Galvanised steel or iron is the traditional piping material in the plumbing industry for the conveyance of water and wastewater. Although still used throughout the world, its popularity is declining. The use of galvanised steel or iron as a conveyer for drinking water is problematic where water flow is slow or static for periods of time because it causes rust from internal corrosion.Types of Galvanized Steel Sheets IntroductionElectric- Galvanized Steel Sheet: oil : Form a protection layer on steel sheet surface, reduce corrosion and scratch: Phosphating : Form dense fine phosphating film on steel surface to reduce corrosion.

The seams of these pipes may be spiral-butt, straight or spiral-lap. The process of making these pipes begins with hot rolled sheets or plates of steel.Passivating carbon steel / when toMar 27, 2009 · Really, steel passivating is not very effective for this use as DI water will corrode your pipe again. If it were stainless, you could pickle and re-passivate, but carbon steel can't be permanently passivated as stainless. If you can't take your pipe out and can't replace it, I would suggest chemical cleaning and soft protection (hydrochloric acid, rinse, then some steel protection as sodium nitrite and rinse with DI water), then paint your pipe
