BDR Pharmaceuticals International Interview Questions, Process, and Tips

The necessary checking procedure of a glass lined reactor involves visual inspection, pressure testing, and checking for any signs of corrosion or damage.

• Perform a visual inspection of the glass lining to check for any cracks, chips, or signs of wear.

• Conduct a pressure test to ensure the reactor can withstand the required operating pressure.

• Check for any signs of corrosion on the glass lining, especially in areas expos...read more

There are two types of vacuum systems: liquid ring and dry vacuum systems.

• Liquid ring vacuum systems use a liquid as a sealant to create a vacuum.

• Dry vacuum systems use oil-free pumps to create a vacuum.

• Examples of liquid ring vacuum systems include steam jet ejectors and water ring vacuum pumps.

• Examples of dry vacuum systems include scroll pumps and turbo molecular pumps.

Flush bottom valves are used to drain liquids from tanks. Troubleshooting involves identifying and fixing issues with the valve.

• Check for leaks or blockages in the valve

• Inspect the valve for damage or wear and tear

• Ensure that the valve is properly installed and tightened

• Verify that the valve is compatible with the liquid being drained

• Consult manufacturer's instructions or seek expert advice if necessary

Steam traps are devices used to discharge condensate and non-condensable gases from steam systems.

• There are three main types of steam traps: mechanical, thermostatic, and thermodynamic.

• Mechanical steam traps use a float to open and close a valve.

• Thermostatic steam traps use a temperature-sensitive element to open and close a valve.

• Thermodynamic steam traps use the difference in pressure between steam and condensate to ...read more

U-loop is required in steam lines to prevent thermal expansion and contraction.

• U-loop is a type of expansion joint used in steam lines.

• It is used to absorb the thermal expansion and contraction of the pipe.

• It prevents the pipe from buckling or breaking due to thermal stress.

• U-loop is typically installed in vertical steam lines.

• It is also used in horizontal steam lines where there is limited space for expansion.

• U-loop i...read more
