Técnicas Reunidas Civil Designer Interview Questions and Answers

Layout details of support type equipment in previous project

• Support type equipment included pipe supports, hangers, and anchors

• Layout involved determining locations for supports based on piping design and stress analysis

• Consideration given to weight, thermal expansion, and vibration of piping system

• Supports were designed to ensure proper alignment and stability of piping system

Various pressure tests are conducted on valves including hydrostatic test, pneumatic test, and cryogenic test.

• Hydrostatic test is conducted by filling the valve with water and pressurizing it to a specified pressure to check for leaks.

• Pneumatic test involves using air or nitrogen to pressurize the valve and check for leaks or defects.

• Cryogenic test is performed at low temperatures to ensure the valve can withstand extr...read more

Safety considerations in designing piping systems are crucial for preventing accidents and ensuring the integrity of the system.

• Ensuring proper material selection to withstand the intended pressure and temperature conditions

• Implementing proper support and restraint systems to prevent excessive stress and vibration

• Incorporating adequate access points for maintenance and inspection

• Following relevant codes and standards s...read more

BMD for sway frame is a diagram showing the variation of bending moment along the length of the frame.

• BMD for sway frame will have a shape similar to a zigzag pattern due to the presence of sway in the frame.

• The bending moment will be maximum at the points where the frame experiences maximum sway.

• The BMD can be drawn by analyzing the internal forces and moments acting on the frame.

Drawing piperack elevations involves creating detailed drawings of the structure from different viewpoints.

• Start by determining the dimensions and layout of the piperack

• Use software like AutoCAD to create accurate and detailed drawings

• Include all necessary details such as pipe sizes, supports, and connections

• Label all components clearly for easy understanding

• Review and revise the drawings as needed for accuracy
