Reactors are designed to

contain chemical reactions. They may be exothermic or endothermic and can be batch reactors, continuously stirred tank reactors or fluidized bed reactors among others.

Vapor compression chiller

technology uses four basic types of compressors - reciprocating, screw driven, scroll and centrifugal. All mechanical machines where over-pressure protection may be necessary.

Primary Relief
Secondary Relief
Rupture discs are often used

to isolate the inlet of safety relief valves to protect the valve internals from corrosive processes. ASME Section VIII recognizes the use of rupture disks under Paragraph UG-127.

Heat transfer from one medium

to another is widely used in chemical plants, petrochemical plants, petroleum refineries, gas processing and power plants and often require specialized over-pressure protection.
