Traction on Demand Interview Questions and Answers

A floating type heat exchanger is a type of heat exchanger that uses a floating head to allow for thermal expansion.

• The floating head allows for thermal expansion and contraction of the tubes without damaging the shell or tubesheet.

• This type of heat exchanger is commonly used in high temperature and high pressure applications.

• Maintenance of the floating head is important to ensure proper operation and prevent leaks.

• Examples of industries that use floating type heat exchangers...read more

In-Service Inspection of Pressure vessel, Tanks, Heat Exchanger

• In-service inspection involves assessing the condition of pressure vessels, tanks, and heat exchangers while they are in operation.

• It is important to identify any potential defects or damage that could compromise the safety and functionality of these equipment.

• Inspections may include visual examination, non-destructive testing, and monitoring of operating parameters.

• Regular inspections help ensure compliance with ...read more

Hydrotesting is a process of testing the strength and integrity of a pipeline or vessel by filling it with water or another liquid.

• Hydrotesting is done to ensure that the pipeline or vessel can withstand the pressure it is designed for.

• During hydrotesting, the pipeline or vessel is filled with water or another liquid and pressurized to a level higher than its normal operating pressure.

• The pressure is held for a specified period of time to check for leaks or other defects.

• Hydr...read more

Heat exchanger maintenance involves regular cleaning, inspection, and testing to ensure optimal performance and prevent breakdowns.

• Regularly clean the heat exchanger tubes to remove any buildup of dirt, debris, or scale

• Inspect the heat exchanger for any signs of corrosion, leaks, or damage

• Perform pressure tests to check for any leaks or weaknesses in the system

• Replace any worn out or damaged parts to prevent further damage and ensure efficient operation

• Keep a maintenance log ...read more

Damage mechanisms of static equipment refer to the various ways in which these equipment can deteriorate or fail over time.

• Corrosion: The most common damage mechanism, caused by the reaction of metal with its environment.

• Erosion: Occurs when the flow of fluid or particles causes the surface of the equipment to wear away.

• Cracking: Can be caused by stress, fatigue, or material defects, leading to structural failure.

• Cavitation: Formation and collapse of vapor bubbles in a liquid...read more
