Idom Piping Stress Engineer Interview Questions and Answers

Q1. Expansion stress formula
Ans. 
Expansion stress formula calculates the stress caused by thermal expansion or contraction.
• Expansion stress formula is given by: ΔL/L = αΔT, where ΔL is the change in length, L is the original length, α is the coefficient of thermal expansion, and ΔT is the change in temperature.

• The formula can be used to calculate the stress caused by thermal expansion or contraction in piping systems.

• The formula assumes that the mater...read more

Q1. What is bevel angle of piping?
Ans. 
Bevel angle of piping refers to the angle formed between the prepared edge of the pipe and a plane perpendicular to the pipe axis.
• Bevel angle is typically specified in degrees, such as 30° or 45°.

• It is important for welding processes to ensure proper fit-up and joint strength.

• Different bevel angles may be required based on the material being used and the welding procedure being employed.
