Mechanical Piping Engineer Interview Questions and Answers

Piping refers to a system of pipes used to transport fluids, while tubes are hollow cylinders used for structural purposes.

• Piping is used to transport fluids, such as water, oil, or gas, from one location to another.

• Tubes are primarily used for structural applications, such as supporting buildings or carrying loads.

• Piping is typically larger in diameter and has thicker walls compared to tubes.

• Piping is often connected using fittings and joints, while tubes are usually welded ...read more

A pipeline is a system of pipes used for transporting liquids or gases over long distances.

• Pipelines are used for transporting oil, gas, water, and other fluids.

• They are often used in the energy industry to transport crude oil and natural gas from production sites to refineries and processing plants.

• Pipelines can be made of various materials, including steel, plastic, and concrete.

• They can be underground, above ground, or underwater.

Material like CS, SS, and AS can be identified based on their composition, properties, and application.

• CS stands for Carbon Steel, which contains mainly carbon and iron. It is commonly used in construction and industrial applications.

• SS stands for Stainless Steel, which contains chromium and nickel in addition to iron. It is known for its corrosion resistance and is used in food processing, medical equipment, and aerospace.

• AS stands for Alloy Steel, which contains elements li...read more

Weld visual inspection is required to ensure the quality and integrity of the welds.

• Visual inspection helps to detect any surface defects or discontinuities in the welds.

• It ensures that the welds meet the specified standards and requirements.

• Visual inspection is a non-destructive testing method that is cost-effective and easy to perform.

• It helps in identifying issues early on, preventing potential failures or accidents.

• Examples: checking for cracks, porosity, incomplete penet...read more
