Features:
- excellent durability and long service life
- precoiled for easier installation
- no surface preparation required
- can be reused
- no minimum quantity
- custom production with any texts and graphics
Dura Markers ara available in various colours and sizes. They can be customised according to the customer's needs.
Installation does not require any surface preparation, because Dura Marekers bond only to themselves, not the pipe.
Design and dimensions
A-SPE Pipemarking Tapes and Markers can be produced in accordance to the particular requirements of our customers. According to the request they can be designed to comply with one of the following regulations:
- ISO 14726:2008
- BS-1710 / BS-4800
- ANSI/ASME A13-1
- TRGS-201



A-SPE Tapes and Markers can be printed in any language based on the translation provided by the customer.
Each pipe marker is dedicated for particular pipe diameter. Below table shows recommended markers dimensions for most popular nominal pipe sizes. Adjusted marker length is always followed by suitable font and arrow size.
Below sizes consider minimum 30mm overlap, however they do not consider any additional pipe coatings like insulations etc. The information about insulation thickness or other coating should be provided with other details necessary for the quotation.

Installation tips
Important: During application the tape should overlap 2-3 cm
According to the ISO 14726:2008 regulation the following advises shall be considered during the pipe markers and tapes installation:
- The markers should be installed within a distance of 3-5 meters of the length of the horizontal and straight pipelines, whereby the local conditions may require a more frequent marking due to pipe bends or the close proximity of pipes for different services.
- In case of the system valves the markers should be installed in a distance of approximately 75mm from the corresponding flange.
- The markers should appear at each penetration point in bulkheads, walls or decks.
- In areas with the piping system junctions the markers should be installed on each side of the junction.
- In case of the vertical piping system the markers should be applied on height of approximately 170cm to ensure good visibility at eye level of the observing persons.
The exact estimation of the amount of markers and installation points is determined during the material take-off process. A-SPE specialists can offer you a professional consulting on base of the provided pipe lines schemes and detailed specification.
