Ashapura Forwarders Interview Questions and Answers

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

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

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 regularly to prevent fouling and blockages that can reduce its eff...read more

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

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

T4S is a standard and specification used in the field of inspection engineering.

• T4S stands for Technical Specification for Structural Steelwork

• It provides guidelines and requirements for the inspection and testing of structural steelwork

• T4S covers various aspects such as material properties, fabrication, welding, and non-destructive testing

• It ensures the quality and safety of structural steelwork in construction projects

• For example, T4S may specify the acceptable levels of we...read more
