How thick is sch 40 stainless steel pipe?

SCH 40 refers to the wall thickness of the stainless steel pipe and is a vital specification to consider during pipe selection. It is one of the most commonly used schedules in stainless steel piping due to its balanced attributes.


SCH 40 strikes a balance between being robust enough to handle considerable pressure and fluid loads while remaining cost-effective and easy to work with. Other thicker schedules, such as SCH 80 or SCH 160, are more suitable for extreme pressure requirements, but they may come at a higher cost and increased difficulty during installation.


The "SCH" in SCH 40 stands for "schedule," indicating the standardized wall thickness. It's essential to comprehend how this schedule system works. For SCH 40 stainless steel pipes, the wall thickness corresponds to the pipe's nominal size, expressed in inches.
