Minimum Wall Thickness on Inspection:
- The following equation, upon which this table is based, may be applied to calculate minimum wall thicknesses from nominal wall thickness:
tn * 0.875 = tm
Where:
tn = nominal wall thickness, in. [mm], and
tm= minimum wall thicknesses, in. [mm] - The wall thickness is inch-pound units is rounded to three decimal places in accordance with the rounding method of Practice E29. The wall thickness in SI units is rounded to one decimal place in accordance with the rounding method of Practice E29.
- This table is a master table covering wall thicknesses available in the purchase of different classifications of pipe, but it is not meant to imply that all the walls listed herein are necessarily obtainable for the applicable product specification.
