The KKS system (Kraftwerk – Kennzeichen - System) is commonly used for coding and marking pipelines and fittings data. The markers used must be suitable for the environment of the object being marked (temperature, environmental factors, etc.) and ensure marking legibility for the service life of the facility. Markers should be mounted in visible places, on fixed, non-removable components of the facilities. A plate made of properly selected material can be riveted to a steel holder and the whole assembly attached to a pipeline using a cable tie. Tie length should be selected according to the diameter/circumference of the pipe.
