How to Calculate Minimum Wall Thickness | Hunker

A 0.7752 inch minimum thickness multiplied by a 15 percent tolerance or 115 becomes 0.7752 x 1.15. This equals 0.89147 inches, or almost 0.9 inch minimum pipe wall thickness. If a safety factor of two was required, the minimum thickness of 0.7752 x 2 would give a minimum wall thickness of 1.5504 inches.
