ANSI B36.19 standard included stainless steel seamless steel pipes and welded steel pipes. but ANSI B36.10 standard included seamless steel pipes and welded steel pipes.
The steel pipe data chart below can be used to find pipe sizes .diameters. wall thickness. working pressures and more. The chart is based on ASME/ANSI B 36.10 standard Welded and Seamless Wrought Steel Pipe and ASME/ANSI B36.19 standard Stainless Steel Pipe. Regardless of schedule change , pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). As the schedule number increases, the wall thickness increases, and the actual bore is reduced
For example
4 inches (100 mm) Schedule 40 pipe has an outside diameter of 4.500 inches (114.30 mm), a wall thickness of 0.237 inches (6.02 mm), giving a bore of 4.026 inches (102.26 mm)
4 inches (100 mm) Schedule 80 pipe has an outside diameter of 4.500 inches ( 114.30 mm), a wall thickness of 0.337 inches (8.56 mm), giving a bore of 3.826 inches (97.18 mm)
1 in (inch) = 25.4 mm
The pipe schedule number is the ratio of the design pressure of the pipe to the allowable stress of the material at the design temperature multiplied by 1000 and rounded.
That is: Sch = P / [σ] t × 1000
ANSI B36.10 standard wall thickness grades: sch10, sch20, sch30, sch40, sch60, sch80, sch100, sch120, sch140 and sch160 ect ;
ANSI B36.19 standard wall thickness grade: sch5s, sch10s, sch40s, sch80s ect
