Q. Can we use galvanized pipe for gas?

Answer

Well! When delivering gas, the use of pipe that has been galvanised is not advised. The galvanised coating makes galvanised pipe unsuitable for use with gas, thus you should avoid using it. Your gas regulators and burner units will eventually become clogged with flakes of the galvanised steel since these flakes will flake off over time. Never combine galvanised and black iron; otherwise, the areas where they come into contact will experience rapid corrosion.
