A physical object that is a circular plate with no central opening and holes to match mating flanged ends. It is also equipped with a handle.

An 'artefact' that has different nominal pipe size at the two ends, intended to connect pipes or piping components.

A support intended to support one or more pipes.

A physical object that has three piping ends in T-shape, including a branch at 90 degrees.

A fluid conductor that consists of pipe, possibly also including pumps, valves, and control devices, intended for conveying liquids, gases, or finely divided solids.

A physical object used in or in connection with a piping system.

A bellows that is a flexible corrugated tubular element providing axial and radial flexibility and pressure containment.

A piping system that is situated within the frame and distributes purge gas inside the frame.

Is a piping assembly of piping components to be pre-fabricated as one item.

A lift check valve that has a free gravity or spring loaded piston type closure member.

A fluid sensor producing a differential pressure by means of two straigth tubes mounted in line with the direction of the fluid movement. One tube is open-ended and measures the stagnation pressure of the fluid. The other tube is closed in front but has openings along the tube to measure the static pressure of the fluid.

A differential pressure flow meter utilizing a pitot tube (a probe with an open tip) that is inserted into the flow field.

A non-corrugated plate heat exchanger that has flat core plates separated by u-shaped fins or corrugated plates.

A heat exchanger using plates as the device for separating the two fluids and across which the energy is transferred.

A control valve that is also a plug valve and an actuated valve.

A rotary valve that has a quarter turn action in which the closure member is a cylindrical or tapered plug which operates by rotating on its axis and sealing against a downstream seat.

An actuator that is intended to be operated by pneumatic power.

A mechanical controller that is using pneumatic components to execute its function.

A conveyor for transporting dry, free flowing, granular material in suspension within a pipe or duct by means of a high-velocity airstream or by the energy of expanding compressed air within a comparatively dense column of fluidized or aerated material.

A cylinder where the piston is actuated by compressed air.

A motor that is driven by compressed gas. Typically air.

A pilot switch the actuating system of which is operated by a moving part of a machine, when this part reaches a predetermined position.

A transmitter that is producing a standardized output signal dependent of a received input signal from a position detector.

A handheld or fixed device designed to identify and record the location of an object on the earth's surface. GPS, GALILEO, SYLEDIS, HYPERFIX, LORAN-C, DECCA etc. are all brands and working on different networks.

Elements like impellers rotating by the pressure of the fluid in a closed conduit to measure the flow of a liquid.
