The NPS size represents the approximate inside diameter (not outside) of the pipe; if the schedule number on a set size is changed, it does effect the inside diameter (ID) but not the outside diameter (OD). or Sch., for example – "2-inch diameter pipe, Schedule 40"). If not, schedule 40 PVC is more than enough for many pressurized and non-pressurized jobs. This should be considered when piping is specified for 5, 10, 20, 30, 40, 80, 120, 160. At Metal Supermarkets, we supply a wide range of metals for a variety of applications. Despite its deceiving title, schedule doesn't have anything to do with time. Additionally, elements like vanadium, copper, chrome, nickel, molybdenum, and chromium can be found in trace amounts in the ASTM A53 Grade B Schedule 80 Pipe . Also, while the schedule number can be the same on different sized pipes, the actual wall thickness will be different. Pipe can also be rated as DWV (for drain, waste, and vent). The only real difference is that DWV PVC is not made to handle pressurized uses like schedule 40 parts are. DWV parts look very similar to standard white schedule 40 PVC pipe and fittings. What is the meaning of Schedule 40 pipe? The name NPS is based on the earlier Iron Pipe Size (IPS) system. When working with pipe, it is common to describe them by their “schedule”.
