Application

  • Two-part multi-range coupling designed for repairing the sleeves of fibre cement, cast and plastic pipes.
  • Due to the shape of the coupling, the leaking connection sleeve does not have to be dismantled.
  • The coupling can also be used for drilling pipes under pressure.

Characteristics

  • The cone-shaped sealing collar on the pipe allows for a pipe tolerance of up to 30 mm.
  • The separate sealing packs for the specific pipe make it possible to centre the coupling exactly.
  • The sealing collar is made from EPDM rubber.
  • The outlets at the top and bottom facilitate an assembly without pressure, as well as additional connection options.
  • Flange connection compound
    - according to EN 1092-2
  • Operating temperature
    - max. 40 °C
  • Druckstufe PN 16
    - Andere Druckstufen auf Anfrage möglich
  • Der Korrosionsschutz dieser Mehrbereichskupplung ist mit der bewährten Rilsan®-Beschichtungstechnik.

Material

  • Gehäuse und Spannring
    - Stahl mit Rilsan® Beschichtung
  • Dichtung
    - Standard EPDM nach W 270, NBR auf Anfrage
  • Zugsicherungselemente
    - Gehärteter Stahl mit Dacromet®-Beschichtung (Dauergeschmierte Schrauben)
  • Schrauben
    - Stahl mit Dacromet®-Beschichtung (Dauergeschmiert)

Caution

  • The shape must be aligned with a specific coupling on site.
  • Other nominal widths on request
