Pipeline marking

Legible pipeline labelling is crucial to occupational safety and the correct operation of installations. Both Polish and and European standards require that pipelines are marked with a colour which identifies the substance that flows inside the pipes and also a direction arrow which specifies the direction of the medium's flow. It is important for the colour and the directional arrow to be visible from all sides of the pipeline. For additional identification, it is advisable that the pipework is labelled with the description of the medium and its parameters. Labelling the pipeline with a number or an alphanumeric code greatly facilitates its identification by the personnel.

The pipe marking should be mounted frequently enough for it to be spotted immediately, particularly in areas which are ambiguous, e.g. on branching, upstream and downstream of a pump, and in places where the marking can make the operation of an installation more efficient.
