What is the difference between a pipe schedule and a pipe size?
Pipe Schedule vs Pipe Size 1 Standard (STD) is identical to SCH 40 up to NPS 10. All larger sizes of Standard (STD Schedule) have 9.53 mm wall thicknesses. 2 Extra-Strong (XS) is identical to SCH 80 up to NPS 8. All larger sizes of Extra-Strong have 12.70 mm wall thicknesses. 3 The double Extra Strong (XXS) wall is thicker than SCH 160 from NPS 1/8 to NPS 6, and SCH 160 is thicker than the XXS wall for NPS 8 and larger. 4 With an increase in pipe thickness internal diameter of the pipe reduces as the pipe outer diameter remains constant.
