When you define the fitting thickness for the bend, CAESAR II changes the thickness only of the curved portion of the bend element. The thickness of any preceding or following straight pipe is unaffected.

The specified fitting thickness applies only for the current elbow and is not persisted to any subsequent elbows in the job.

Stresses at the elbow are calculated based on the section modulus of the matching pipe as specified in the B31 codes. However, stress intensification factors and flexibility factors for the bend are based on the elbow wall thickness.

In the following example, the elbow at node 10 has a thickness larger than the matching pipe wall. The matching pipe has a thickness of 0.5.
