## Stress Analysis Interview Questions:- Part-3

18. Why do we provide drip leg in steam line? To remove condensate when there is a rise of same in the pipe along the flow direction. If drip leg is not provided in steam line, the condensate which forms inside the pipe will result in water hammer effect causing damage to piping system. 19. What is the design standard followed for ... Read More »

## Questions Related to Stress Analysis:- Part-2

11. How do you calculate the stress developed due to thermal expansion? Stress developed, Σ = ∈ x α , (α= Δ L/L) ……. Where, E = young’s modulus. Δ L = increase in length due to thermal expansion. L = original length of the pipe. 12. How do you calculate the thermal expansion in a pipe?  Δ L = ... Read More »

## Questions Related to Stress Analysis:- Part-1

1. What is the objective of stress analysis? A . To ensure that the stresses in piping components in the system are within allowable limits. B. To solve dynamic problems developed due to mechanical vibration, fluid hammer, pulsation, relief valves, etc. C. To solve problems associated due to higher or lower operating temperature as: – I. Displacement stress range. II. ... Read More »

## Questions Related to Pipe Under Stress:- Part-2

7. What are the other stresses against which the design of piping is safe guarded? A. Principal stress. B. Shear stress. Apart from the stress which is normal to the surface of the crystal as mentioned in question No. 4, the grains would have been oriented in the pipe wall in all possible orientations. The above stresses (axial, circumferential and radial stress) ... Read More »

## Questions Related to Pipe Under Stress:- Part-1

1. What are primary loads? Mention some of primary loads? These are typically steady or sustained types of loads. These loads have their origin in some force acting on the pipe causing tension, compression, torsion etc leading to normal and shear stress. Primary loads are not self limiting. Some of the primary loads are as:- A. Internal fluid pressure B. External ... Read More »

## Question Related to Mechanical Design Fundamentals:- Part–2

1. How much design temperature shall be considered for the structural parts which are heated by steam, thermic fluid etc? Design temperature shall be the highest expected temperature of the heating media or highest expected body part temperature plus 10C. Here, 10 C is the safety margin. 2. Define proof stress? It is also called 0.2% proof stress. It is the stress ... Read More »

## Question Related to Mechanical Design Fundamentals:- Part-1

1. What are the failures with reference to the structural design? Failure of a structural part can occur by :- A. Excessive elastic deformation. B. Excessive non- elastic deformation. C. Fracture. Any design has to guard against these perceived failures. 2. What are the factors upon which the mechanical properties of material are dependent? Mechanical properties of any material of ...

## Question Related to Equipment and Piping Layout:- Part-2

9. What is line routing diagram? A line routing diagram is a schematic representation of all process and utility – piping system drawn on a copy of plot plan. This diagram does not show the exact locations, elevations or interference but it locates the most congested area. 10. How do you calculate the width of pipe rack? W = (f X n ... Read More »
