![]() ![]() Most scientific calculators (and even the calculators built into smart phones) have these functions. Minimum thickness of formed bends is calculated for the inside radius, the oputside radius, and the centerline radius. Bend thinning on the outside radius is estimated using the method from ASME B31.1. The estimated minimum bend thickness after thinning should be the required minimum bend thickness on the outside radius (extrados). Use the goal seek option to calculate the required straight pipe nominal wall thickness (before bending), for the minimum thickness on the outside radius (after bending). The allowable pressure for miter bends is calculated from the nominal wall thickness. Use the goal seek option to calculate the required miter bend nominal wall thickness for the design pressure. Use the workbook ASME B31.3 data tables to look up allowable stress data.

Bend thinning on the outside radius is calculated using an approximate method from ASME B31.1 table 102.4.5. Use the goal seek option to calculate the required straight pipe nominal wall thickness from the minimum wall thickness on the outside radius.
