SCH 40 Stainless Steel Pipe dimensions

"SCH 40 stainless steel pipe" is a stainless steel pipe with a specific wall thickness grade in the American standard system. It is used in medium-pressure scenarios and needs to be queried in combination with the nominal diameter. In actual applications, it is necessary to confirm the standard (such as ASME B36.19) and material grade (such as 304, 316 stainless steel) to ensure applicability.

SCH 80 Stainless Steel Pipe Dimensions Table

Outer diameter tolerance: ±1% (ASTM A312 standard, such as 114.3 mm allows ±1.14 mm).
Wall thickness tolerance: small size pipe ±12.5%, large size pipe ±10% (such as 6.02 mm allows ±0.75 mm).
Material difference: 304, 316L and other materials have slightly different densities (7.9~8.0 g/cm³), and the weight error is usually <1%.
