Dimensional Standards for Pipes
ASME scheduled pipes have 2 common dimensional standards namely:
ASME B36.10 – Welded and Seamless Wrought Steel Pipes
– Sizes: 1/8” – 80” Schedules: 10 / 20 / 30 / STD / 40 / 60 / XS / 80 / 100 / 120 / 140 / 160 / XXS
ASME B36.19 – Stainless Steel Pipe
– Sizes: 1/8” – 30” Schedules: 5S / 10S / 40S / 80S
SCH 40S / SCH 40 / STD and SCH 80S / SCH 80 / XS have the same wall thicknesses of 9.53mm and 12.7mm respectively.
