Aarvi Encon Interview Questions, Process, and Tips

RBI stands for Risk-Based Inspection, a method used to optimize inspection schedules based on risk levels.

• RBI is a methodology used to determine the most effective inspection plan based on the risk associated with each piece of equipment or component.

• It involves assessing the likelihood of failure and the consequences of failure to prioritize inspection efforts.

• RBI helps in optimizing inspection intervals, reducing dow...read more

Hot tap is a method used to create a connection to a pressurized system without shutting it down.

• Hot tap involves drilling into a pressurized system to create a branch connection.

• It is commonly used in pipelines to install new equipment or perform maintenance without interrupting the flow.

• Specialized equipment and procedures are used to ensure safety and integrity of the system during hot tapping.

• Examples include addin...read more

Inspection procedure for pressure vessel involves visual inspection, non-destructive testing, and documentation review.

• Visual inspection of the exterior and interior surfaces of the pressure vessel

• Non-destructive testing methods such as ultrasonic testing, radiography, and magnetic particle testing

• Review of documentation including design specifications, fabrication records, and previous inspection reports

Various types of NDT methods are used including ultrasonic testing, radiographic testing, magnetic particle testing, liquid penetrant testing, and visual testing.

• Ultrasonic testing is used to detect internal flaws in materials by sending high-frequency sound waves through the material.

• Radiographic testing uses X-rays or gamma rays to inspect the internal structure of a component.

• Magnetic particle testing is used to det...read more

RTD stands for Resistance Temperature Detector, a sensor that measures temperature by correlating the resistance of the RTD element with temperature. Thermocouple is a sensor that measures temperature using the voltage generated by the junction of two different metals.

• RTD measures temperature by changes in electrical resistance

• Thermocouple measures temperature by voltage generated at the junction of two different metal...read more

Transmitter calibration ensures accurate measurement by adjusting the output signal to match the input signal.

• Calibration involves comparing the output of the transmitter to a known input signal and making adjustments as needed.

• Use calibration equipment such as a signal generator and multimeter to perform the calibration.

• Follow manufacturer's instructions and guidelines for proper calibration procedures.

• Document the ca...read more

There are several types of valves used in mechanical engineering for controlling the flow of fluids or gases.

• Types of valves include ball valves, gate valves, globe valves, butterfly valves, check valves, and pressure relief valves.

• Valves can be classified based on their function (e.g. isolation valves, control valves), design (e.g. rotary valves, linear valves), or material (e.g. brass valves, stainless steel valves).
