A facility on a pipeline for inserting and retrieving a scraper or pig.

Heavy stakes or posts installed to support the foundations of a superstructure.

A pressure relief valve that uses a pilot valve to indirectly activate the main valve.

A non-reclosing pressure-relief device actuated by the static differential pressure between the inlet and outlet of the device.

A pinch valve is an actuated membrane valve that is comprising a flexible tube, either exposed or enclosed in a body. The tube is pinched to close by mechanical means.

A membrane valve that is comprising a flexible tube, either exposed or enclosed in a body. The tube is pinched to close by mechanical means.

A physical object that is a long tube or hollow body intended for conduction of liquid, gaseous or finely divided solid materials, or used for structural purposes.

A physical object that is used to change piping direction with a non-standard radius.

An artefact which is intended for bending pipes.

A device that is designed for easy washing and dope application of drill pipe threads and collar threads.

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.

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.

Piping speciality item is an inline piping component that is not pre-defined within the existing piping specification

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.
