Megha Engineering & Infrastructures Piping Engineer Interview Questions, Process, and Tips for Experienced

Pinging in pipeline ASME CODE refers to the process of using ultrasonic testing to detect defects or anomalies in the pipeline.

• Pinging involves sending ultrasonic waves through the pipeline to detect any abnormalities in the material or welds.

• This technique is commonly used in the inspection of pipelines to ensure they meet the standards set by the ASME CODE.

• Pinging helps identify potential issues such as cracks, corro...read more

Corrosion coupons are used to monitor the rate of corrosion in a system and to determine the effectiveness of corrosion inhibitors.

• Corrosion coupons are small metal strips or discs that are inserted into a system to measure the rate of corrosion over time.

• They are made of the same material as the system being monitored, allowing for accurate assessment of corrosion rates.

• Corrosion coupons are typically retrieved period...read more

P&ID stands for Piping and Instrumentation Diagram, while PFD stands for Process Flow Diagram. They are both used in engineering to represent processes and systems.

• P&ID shows the piping of the process flow system, including the equipment and instrumentation used.

• PFD shows the overall flow of the process, including major equipment and control loops.

• P&ID includes more detailed information like pipe sizes, materials, and ...read more

Types of instruments used in piping engineering and their applications

• Pressure gauges - measure pressure in pipes to ensure safe operation

• Flow meters - measure the flow rate of fluids in pipes for monitoring purposes

• Temperature sensors - monitor the temperature of fluids in pipes to prevent overheating

• Level indicators - indicate the level of fluids in tanks connected to pipes for control purposes

• Control valves - regula...read more
