Incidental pressure : Pressure occurring in a pipeline with limited frequency and during limited periods of time.

Hot bend : A bend made under factory conditions by hot working billets, plates or pipes.

Fluid : A substance which is transported through a pipeline in liquid or gaseous phase, or a combination of these.

Flowline : A pipeline transporting untreated hydrocarbons and other reservoir fluids.

Flammable fluid : A flammable fluid has a flash point lower than 100 ☌.

Emergency shutdown valve : Valve for isolating a pipeline from a plant in case of emergency situations within the plant.

Design pressure : The internal pipeline pressure used in the determination of the pipeline wall thickness requirements.

Design factor : Ratio of the hoop stress created by the design pressure and the SMYS of the pipeline material.

Consequence : The result of an event in terms of human safety, damage to the environment and economic loss.

Commissioning : An activity where the fluid to be transported is initially introduced into a pipeline.

Cold bend : A bend made from linepipe at ambient temperature, normally on the construction site, using a mechanical bending machine.

Branch pipe : Pipe connected to a pipeline of equal or larger diameter, using a tee-piece.

A block valve is normally either fully opened or fully closed.

Block valve : Valve for interrupting the flow or to shut-in a section of a pipeline.

Barred tee : Tee-piece provided with bars across the internal bore of the branch pipe to prevent entry of a pig.

Assembly : An arrangement of pipes and components such as a crossing, a pig trap, a block valve station or a riser.

Here is a comprehensive list of these terms and definitions. Pipeline Engineering is a specialized branch of engineering with its own terms and definitions.
