Q1. Types of relief devices
Ans. 
Relief devices are safety devices used to protect equipment and personnel from overpressure situations.
• Types include pressure relief valves, rupture discs, and safety valves

• Pressure relief valves are the most common type and operate by opening to release excess pressure

• Rupture discs are non-reclosing devices that burst at a predetermined pressure to relieve pressure

• Safety valves are similar to pressure relief valves bu...read more

Q2. Types of relief devices are Conventional, Balance bellow & Pilot operated.
Ans. 
Relief devices such as Conventional, Balance bellow, and Pilot operated are used in process engineering to protect equipment from overpressure.
• Conventional relief devices are simple and rely on a spring-loaded mechanism to relieve pressure.

• Balance bellow relief devices use a bellows to balance the pressure on both sides of the valve, allowing for accurate pressure relief.

• Pilot operated relief devices use a pilot valve ...read more
