In fire and explosion prevention engineering, purging refers to the introduction of an inert (i.e. non-combustible) purge gas into a closed system (e.g. a container or a process vessel) to prevent the formation of an ignitable atmosphere. Purging relies on the principle that a combustible (or flammable) gas is able to undergo combustion ...
A gas non-return valve (NV), which: prevents dangerous gas mixtures. ensures the gas only flows in the intended direction. and a flame arrestor (FA), which: cools the flame to below the ignition temperature of the gas or gas mixture. prevents flashback. In addition to these two basic safety functions a flashback arrestor can also have a:
“Kill” the well (prevent the flow of formation fluid, influx, from the reservoir into the wellbore); Seal the wellhead (close off the wellbore); Sever the casing or drill pipe (in case of emergencies). In drilling a typical high-pressure well, drill strings are routed through a blowout preventer stack toward the reservoir of oil and gas
A shutdown valve (also referred to as SDV or emergency shutdown valve, ESV, ESD, or ESDV; or safety shutoff valve) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to people, equipment or the environment.

A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...
