Piping Stress Engineer Interview Questions and Answers for Freshers

SIF stands for Stress Intensification Factor. It is a dimensionless factor used in piping stress analysis to account for local stress concentrations.

• SIF is used to calculate the maximum stress in a piping system at locations where there are changes in geometry, such as elbows, tees, and reducers.

• It is a multiplier applied to the nominal stress to account for the increased stress caused by the local geometry.

• SIF values are typically obtained from industry standards and codes, ...read more
