Lap welded steel infill plates form a dome profile to withstand the gas pressure in the gas space beneath it. For higher pressure gasholders the infill plates are lap welded on both sides, whereas, low pressure gasholders are only welded on the top side. The fully welded piston deck forms a gas tight surface, which rests on the piston support ...
A positive pressure enclosure, also known as a welding habitat or hot work habitat, is a chamber used to provide a safe working environment for performing hot work in the presence of explosive gases or vapors. They are commonly used in welding environments and are associated with the offshore oil industry. [1]
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas (coal gas or formerly also water gas) is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap.
E-SAPI/X-SAPI ballistic plates: Armored plates (of a shape and curvature to be placed against the body) that provide protection from explosively-formed projectiles. Pelvic Protection System : To reduce casualties and minimize damage to vital areas of the body the U.S. Army teamed with other organizations and the industry to develop and rapidly ...
An IED has five components: a switch (activator), an initiator (fuse), container (body), charge (explosive), and a power source (battery). An IED designed for use against armoured targets such as personnel carriers or tanks will be designed for armour penetration, by using a shaped charge that creates an explosively formed penetrator. IEDs are ...

Hot pressure welding: HPW Metals are pressed together at elevated temperatures below the melting point in vacuum or an inert gas atmosphere Aerospace components Hot isostatic pressure welding: 47: HPW A hot inert gas applies the pressure inside a pressure vessel, i.e. an autoclave: Aerospace components Roll welding: ROW
The regulator is adjusted to control the downstream pressure, which will limit the maximum flow of gas out of the cylinder at the pressure shown by the downstream gauge. For some purposes, such as shielding gas for arc welding, the regulator will also have a flowmeter on the downstream side.
