Description

461 10 koppar, vars väggtjocklek uppgår till maximalt 0,5 mm. Pâpress- ningen av pressförbindningen på röränden sker med backarna 6 till en ej visad presstång.
Den med pressförbindningen på röret pâpressade kopparhylsan åstadkommer a) ett aktivt, elektrokemiskt (katodiskt) korrosionsskydd av det rostfria stålet, eftersom koppar i de i fråga kommande vattnen har en mera negativ (oädlare) korrosionspotential än det rostfria stålet, b) en vittgående avtätning av förbindelsen. Däriqenom minskas vattenångdiffusionen genom den icke metalliskatätningsringen och till följd därav även den härmed förbundna anrikningen av i vattnet förekommande ämnen i omrâdet för ringvulsten.
