Pipe marking

Why use pipe marking?

Signwell Oy is a company specializing in pipe markers and process labelling overall.For the past 30 years we have been providing industries across the world with our pipe marking. In co-operation with the authorities in the field, we have raised e.g. PSK0903 in 2023 and in close co-operation with our partners, we are constantly developing our products in accordance with international regulations and standards.

There are laws and standards in every country for the marking of pipelines. The pipe marking is a crucial part of the safety marking system in an industry that provides an safe environment for the workers and visitors on a daily basis. We manufacture pipe marking of different standards e.g. Finland, PSK 0903, Sweden SS741: 17, ISO 20560-. ANSI, ISO 14726, UK 1710 standard, or in accordance with European Union EC Directive 92/58 / EEC standards.

Implementation of pipe marking

The label indicates the clear name of the substance, the direction of flow and the color according to the identification color of the fluid. Pipe marking is a communication tool to identify contents and flow directions of pipe lines. Not only do the pipe marking provide a clear communication of the substances, it also contributes to an safer environment for the personnel during operation as well as maintenance. If abbreviations for substances are also used in the label, they are presented according to PSK 0903.

The size of the text varies depending on the diameter and reading distance of the pipe. If necessary, the name of the fluid may be supplemented immediately by markings indicating pressure, temperature, concentration or other important property. A separate chemical label is used to label hazardous substances. Piping at the beginning and end of the marking line and at each branch and bushings on both sides. The long line is marked with a pipe markers every 10–15 meters and the marking frequency of the hazardous substance line is reduced as necessary. In vertical tubes, the reading direction of the text is from bottom to top. The pipe markings of natural gas pipelines must comply with the standard, eg. PSK0903.

GHS is a globally harmonized system containing nine pictograms, GHS01/ GHS02/ GHS03/ GHS04/ GHS05/ GHS06 / GHS07 / GHS08/ GHS09 for hazardous classified substances developed by The United Nations (UN). These pictograms are used for labelling chemical substances and are being applied together with the pipe markers on pipe lines, on storage tanks and are used in transportation of such goods that require any of the necessary nine GHS symbols.

The NEW ISO 20560 standard implements a global, harmonized hazard identification system for pipe marking systems with uniform graphics, color coding, and a format for safety messages.

Pipe marking tape

The starting point of this standard is a safety information philosophy into which technical information can be integrated. Designing a standard based on these principles creates logical links to existing safety sign standards and global standards to demonstrate hazards.
