Aarvi Encon Inspection Engineer Interview Questions, Process, and Tips

CMLS stands for Corrosion Mechanism and Localized Severity. RBI inspection is a risk-based inspection method.

• CMLS is a method used to assess the corrosion mechanism and severity in equipment.

• RBI inspection is a risk-based approach to prioritize inspection activities based on the likelihood and consequences of failure.

• Example: Using CMLS to determine the corrosion rate in a pipeline and applying RBI to schedule inspecti

A service regulator is a device used to regulate the pressure of gas or liquid in a pipeline or system.

• It is typically installed at the point of entry to a building or facility

• It ensures that the pressure of the gas or liquid is at a safe and consistent level

• It can be adjusted to accommodate changes in demand or supply

• Examples include natural gas service regulators and water service regulators

Under pressure shutoff is a safety mechanism that shuts off the flow of fluid or gas when pressure exceeds a certain limit.

• Under pressure shutoff is commonly used in pipelines, valves, and other equipment that handle fluids or gases.

• It helps prevent accidents and damage to equipment by stopping the flow of fluid or gas when pressure becomes too high.

• Examples of under pressure shutoff devices include pressure relief val...read more

Steps for pressure vessels inspection during maintenance include visual inspection, thickness measurement, non-destructive testing, and documentation.

• Perform visual inspection of the pressure vessel for any signs of damage or corrosion.

• Measure the thickness of the vessel walls using ultrasonic testing or other methods.

• Conduct non-destructive testing such as radiography or magnetic particle testing to detect any defects...read more

UTG stands for Ultrasonic Thickness Gauging, used for measuring thickness of materials. UT stands for Ultrasonic Testing, used for detecting flaws in materials.

• UTG is used for measuring thickness of materials, while UT is used for detecting flaws in materials

• UTG is commonly used in industries like construction and manufacturing to ensure material thickness meets specifications

• UT is commonly used in industries like aero...read more

Interpass in welding refers to the time between welding passes when the metal is allowed to cool down before the next pass is made.

• Interpass is the time between successive welding passes.

• It allows the metal to cool down to prevent overheating and potential defects.

• Proper interpass temperature control is crucial for weld quality.

• Interpass temperature is typically specified in welding procedures.

• Failure to adhere to inte...read more

Welding is a process of joining two or more metal pieces together by melting and fusing them.

• Welding involves the use of heat to melt the base metals and a filler material to form a joint.

• Common welding techniques include arc welding, MIG welding, TIG welding, and spot welding.

• Welding is used in various industries such as construction, automotive, aerospace, and manufacturing.

• Proper welding techniques are crucial for e...read more
