I applied via Recruitment Consultant and was interviewed in May 2019. There was 1 interview round.
Heat exchangers can be inspected using various methods such as visual inspection, non-destructive testing, and cleaning.
Visual inspection of the heat exchanger tubes and fins for any signs of corrosion, erosion, or damage.
Non-destructive testing methods such as ultrasonic testing, radiography, and eddy current testing can be used to detect any defects or cracks in the heat exchanger.
Cleaning the heat exchanger regularl...
Pipe fit up should be checked for proper alignment, gap, and cleanliness.
Check for proper alignment of pipes
Ensure there is no gap between the pipes
Inspect for cleanliness of the pipes
Verify that the pipes are properly supported
Check for any defects or damages in the pipes
In weld visual inspection, we will see the quality of the weld and any defects present.
Quality of the weld
Presence of any defects
Cracks, porosity, lack of fusion, undercutting, etc.
Weld reinforcement and penetration
Alignment and dimensions of the weld
Surface finish and cleanliness
Visual test involves using the naked eye to inspect a surface or material for defects or irregularities.
Ensure proper lighting and angle for optimal visibility
Look for cracks, corrosion, discoloration, or other abnormalities
Compare with reference standards or previous inspections
Use magnifying glasses or borescopes for closer examination
Document findings and report any issues
There are several types of heat exchangers used in various industries.
Shell and tube heat exchanger
Plate heat exchanger
Double pipe heat exchanger
Spiral heat exchanger
Air cooled heat exchanger
Finned tube heat exchanger

I applied via Recruitment Consulltant and was interviewed before Jun 2021. There were 6 interview rounds.
Nitrogen gas is commonly used for hot/live tapping in mechanical engineering.
Nitrogen gas is inert and non-reactive, making it safe to use in hot/live tapping processes.
It helps to create a protective atmosphere to prevent explosions or fires.
Nitrogen gas is readily available and cost-effective.
Other gases like argon or carbon dioxide can also be used depending on the specific requirements.
Various methods can be used for railway/road/river crossings depending on the location and other factors.
Bridges can be built over the crossing
Tunnels can be dug under the crossing
Level crossings can be used for roads
Flyovers can be constructed for roads
Ferries can be used for river crossings
Aqueducts can be built for waterways
Location, traffic volume, and safety considerations must be taken into account when choosing
The procedure for pipe lines welding while route and filling involves several steps.
Clean the area to be welded thoroughly
Tack weld the pipes together
Weld the root pass
Fill the remaining gap with weld metal
Perform post-weld heat treatment if required
Inspect the weld for defects
RT, UT, and magnetic partials are non-destructive testing methods used in engineering.
RT stands for Radiographic Testing and uses X-rays or gamma rays to inspect the internal structure of a material.
UT stands for Ultrasonic Testing and uses high-frequency sound waves to detect flaws or defects in a material.
Magnetic particle testing uses magnetic fields and iron particles to detect surface and slightly subsurface defec...

I applied via Walk-in and was interviewed in May 2024. There was 1 interview round.
Challenges in well testing include equipment malfunctions, environmental factors, and data interpretation.
Equipment malfunctions can lead to inaccurate results.
Environmental factors such as weather conditions or nearby activities can affect testing.
Data interpretation can be complex and require specialized knowledge.
Pressure build-up in the well can also pose challenges during testing.
I applied via Campus Placement and was interviewed before Sep 2022. There were 3 interview rounds.
I would assess the impact of the out-of-tolerance part and determine if it can still function within acceptable limits or if it needs to be reworked or replaced.
Assess the functionality of the part with the out-of-tolerance dimensions
Determine if the part can still meet the overall design requirements despite being out of tolerance
Consider the potential impact on the performance and safety of the final product

The drawing appears to be a mechanical component with multiple parts and dimensions.
The drawing includes various geometric shapes such as circles, rectangles, and lines.
There are labels indicating dimensions and measurements for each part.
The drawing may also include annotations or symbols representing different materials or processes.
It seems to be a detailed technical drawing for manufacturing or assembly purposes.
I applied via Company Website and was interviewed in Aug 2022. There were 3 interview rounds.
Yield strength is the stress at which a material begins to deform plastically, while ultimate strength is the maximum stress a material can withstand before breaking.
Yield strength is the point where a material starts to deform plastically, meaning it will not return to its original shape once the stress is removed.
Ultimate strength is the maximum stress a material can withstand before it breaks or fractures.
Yield stre...
