Process identification

What is process identification

Process identification or process tagging is the marking of equipment and installations. Marking is used to identify all fixed and moving parts of a process during their life cycle. Clear information on process equipment is an essential part of operating, maintaining and preventing malfunctions of an installation. In most situations, the markings reflect the specific asset number, corresponding to the designation in the process diagrams (P&IDs). There are also now alternative intelligent methods such as QR codes, Barcodes and remotely readable RFID tags.

All kinds of parts of process plants can be tagged, such as nanometers, valves, process vessels and pumps. Piping can also be tagged with a line number, either as a separate tag or integrated into the piping marking.

The ISO 25060-1 offers possibilities to depict line numbers and technical information as an integral part of line marking:
“If additional technical information is required by the user, this information shall be the contrast colour black on a white background”- ISO 20560-1:2020

Process identification for marking of equipment and pipes

Divergent materials

Process identification or process tagging is realized through a variety of sign methods. For example, using various materials such as printed stickers or signs, engraved plastic or stainless steel plates in combination with industrial fastening techniques, a process is fully marked. There are many factors that affect the use and durability of process tags; weathering when used outdoors, deterioration and corrosion from chemicals and solvents and, for example, extremely low or high temperatures. There are a number of categories of versions of process identification when classified by materials:

  • Self-adhesive labels / texts
  • Plastic sheets
  • Steel and stainless steel plates
  • Plastic and aluminum slide-in systems

Plates are attached mechanically or with adhesive. This can be done with bracket systems, (steel) wire, plastic binders, special glues and sealants or directly bolted, screwed or nailed to equipment.

QR code and barcode tagging

Process identification can be achieved with an alphabetical and numerical code. When an intelligent marking is required, which is readable with a scanner, markings are performed with a scannable code. QR code and barcode are common code systems that are linked to applications and database management systems. The use of QR code and barcode markings is also suitable for logistical solutions in warehouses, for example.

Line numbering

Pipes can be physically identified in relation to their position in a process. Line numbering concerns both the actual application of a number on the pipe and the representation of the pipe number in the drawing. Line numbering can be an addition to legally prescribed pipe markings. These types of markings can be applied in a number of ways depending on the environment, use and reading distance. Printed self-adhesive labels and contour cut vinyl or polyester texts are the most common marking types when realized as individual markings. The color of the marking should be contrasting to ensure optimal recognition. The finish and type of material of the pipe are important when selecting a type of marking. In the case of stainless steel pipes, for example, chlorine-free materials and types of glue must be taken into account.

RFID Tagging

When there are more requirements for the intelligence of the tagging and readability via various hand-held devices, RFUD tags can be used. RFID stands for Radio Frequency Identification and functions by using detectable frequencies. An RFID chip can send and receive information or data through a microchip and antenna. RFID chips are pre-programmed with the information required by the user. Implementing RFID process tagging requires thorough preparation, planning and connection to management systems and devices via suitable applications and databases. RFID chips and tags can also be attached to or integrated with regular process tagging solutions.
