The Tecsel® Collar is made up of a metallic casing of 0,7 mm thick of galvanised steel or 0,5 mm of stainless steel with attached intumescent graphite sheets of 2,5 mm thick and 30 or 60 mm wide, depending on the collar diameter.
Under the influence of fire, the expandable graphite strip swells and blocks the opening in the plastic pipe, which prevents fire or smoke spreading across various fire sectors.
The Tecsel® collar has been tested according to European standards UNE EN-1366-3 and has a CE marking with ETA-18/0826 (EAD) number.
Tecsel® Collar is closed by fastening the metal clip. The Tecsel® Collar is attached to the supporting structure by means of various holes and the corresponding screws or rivets.
- Check the measurements of the pipe and open the Tecsel® Collar.
- Place Tecsel® Collar as close as possible to the supporting structure.
- Use the metal tab to adjust and to close the collar.
- Screw the collar to the supporting structure using the appropriate fasteners.
