Indwell Welding Piping Inspector Interview Questions and Answers

Piping refers to a system of pipes used to transport fluids or gases from one location to another.

• Piping is used in various industries such as oil and gas, chemical, pharmaceutical, and construction.

• It involves the design, fabrication, installation, and maintenance of pipes.

• Pipes can be made of materials like steel, copper, PVC, or HDPE.

• Piping systems can include fittings, valves, and other components to control the fl...read more

Types of pipes used in piping include steel, copper, PVC, and HDPE.

• Steel pipes: commonly used for high-pressure applications

• Copper pipes: used for water supply lines

• PVC pipes: lightweight and easy to install, commonly used for drainage systems

• HDPE pipes: high-density polyethylene pipes used for underground gas and water lines

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.

There are two main types of cranes: mobile cranes and tower cranes.

• Mobile cranes are versatile and can be easily moved from one location to another. They are commonly used for construction projects.

• Tower cranes are fixed to the ground and are often used for tall buildings or structures that require heavy lifting at great heights.

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
