This formula ensures that the hoop stress does not exceed the material's allowable limit. For low-pressure, thin-wall piping, a simplified version of this formula, known as , is often used. For high-pressure or thick-wall pipes, the full ASME equation or specialized thick-cylinder analysis may be required.

= Weld joint strength reduction factor (for elevated temperatures) = Coefficient valid for valid (depends on material and temperature) To find the , mechanical and structural allowances must be added:
