Aarvi Encon Interview Questions, Process, and Tips for Experienced

The water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.

• The water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and desired strength.

• For example, a typical water cement ratio for a st

Minimum depth of foundation depends on various factors such as soil type, building load, and local building codes.

• Minimum depth of foundation is typically determined by the local building codes and regulations.

• Factors such as soil type, building load, and proximity to trees or other structures can also influence the minimum depth of foundation.

• For example, in areas with expansive clay soils, deeper foundations may be r

Concrete is a composite material made of cement, water, aggregates, and sometimes additives.

• Concrete is versatile and can be customized for different applications.

• There are different types of concrete based on strength, composition, and use, such as ready-mix, high-strength, and lightweight concrete.

• The most common type of concrete used in construction is Portland cement concrete.

• Special types of concrete include self-...read more

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
