Schedule 40 is the typically used pvc type. schedule 80 has a slightly thicker wall. ansi nominal pipe size table specifies the outside diameters of all schedules for a given pipe size to be equal and the inside diameter will vary according to wall thickness..
Actual pipe and material test reports provided would meet or exceed these guidelines. test reports would provide specific and actual details concerning the mechanical and chemical properties of the actual pipe, as well as additional tests results required by astm. schedule 40 black and galvanized steel erw pipe pipe size nominal 1-1/4" 1-1/2" 2. What are astm grades? astm standards define the specific manufacturing process of the material and determine the exact chemical composition of pipes, fittings and flanges, through percentages of the permitted quantities of carbon, magnesium, nickel, etc., and are indicated by "grade".. Pipe size is specified by two designations: a nominal pipe size (nps) for diameter based on inches, and a schedule (sched. or sch.) for wall thickness. nps is often incorrectly called national pipe size, due to confusion with national pipe thread (npt)..
