This Architectural Drawing is AutoCAD 2d drawing of 2" GALVANIZED WALL PROTECTION PIPE, On average, a galvanized steel pipe has a strength that ranges between 150 PSI and 500 PSI. Black pipe is best used for gas lines, not for water lines because it rusts easily, while galvanized pipe is the safer pipe to use in water lines, but it cannot be used to convey gas. Over time, galvanized pipes corrode and rust. The rust that accumulates inside the pipes makes the passages smaller and smaller, which compromises water flow. Not only does this mean very low water pressure, but it can also mean clogs so dense or big that pipes can burst. For more details and information download the drawing file.
