We offer three standards of Dura Markers to satisfy the highest expectations of the market.
Pipe markers and tapes provide clear identification of contents and flow direction of any section of the piping system. Pipe marking allows also to indicate any additional details for temperature, pressure or locations of hazardous conditions to ensure safe work environment in the marine, offshore, oil & gas and process industries.

About Pre-coiled Pipe Markers
High performance pipe markers of special design of a non-adhesive tube which allows an easy installation on wet, oily, cold and dusty pipelines. Pre-coiled markers are equipped with adhesive stripe only on one end, so that they do not adhere to the pipe surface, but they seal to themselves. Do not require surface preparation, can be easily removed and reapplied to other areas.
AS12 Dura Markers are recommended to withstand direct contact to process chemicals, operating temperature up to 130°C, salt spray, sunlight and UV rays, without deterioration for a minimum of 5 years.
All our tapes and markers are digitally printed at an ISO:9001 approved facility with the use of materials of the first-rate quality to ensure the best performance in the most demanding environments.

Incredible durable, reasuable and easy to install
Norms and Standards

Installation tips

Important: During application the tape should overlap 3-4 cm
Properly installed markers serve for many years and improve the level of occupational safety, helping to reduce the amount of downtime and accidents.
According to the ISO 14726:2008 regulation, the following points should be considered during the installation of pipe markers:
- Markers should be installed within a 3-5m distance between each marking point on a horizontal and vertical pipeline. Branched pipes or close proximity to pipes carrying different media may require a more frequent marking.
- In case of valves, markers should be installed at a distance of approx. 75mm from the corresponding flange.
- Markers should be mounted at all penetration points in walls, bulkheads or decks.
- Markers should be installed on each side of the pipe branch.
- In case of a vertical piping system, markers should be applied at a height of approx. 170cm to ensure good visibility.
The exact estimation of the quantity of markers and installation points is determined at the stage of material preparation. A-SPE specialists can offer you professional advice based on the provided pipeline scheme and detailed specifications.
