Reliance Retail Interview Questions and Answers

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.

• Document all inspection findings and create a maintenance...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 ensuring the strength and integrity of the joint.

• Welding in...read more

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 inspections based on risk levels.

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 valves, rupture discs, and emergency shutdown systems.

• These d...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 interpass temperature requirements can lead to weld defects.

• Ex...read more
