Abstract

Oppfinnelsen vedrører en rørpressforbindelse, bestående av en pressdel (1), som har minst et i tverrsnitt vulstaktig avsnitt (4) som opptar en tetningsring (2), og et dertil tilsluttet, mot en innskyvingsende vendt første sylindrisk utformet (6) samt et fra innskyvingsenden vendt andre sylindrisk utformet avsnitt (9), hvilket andre avsnitt (9) har en mindre innerdiameter enn det første avsnitt (6) og derved danner et anslag, samt et ledningsrør (3) %'iss glattskårene ende etter innskyvingen i pressdelen (1) får anlegg mot anslaget (12) som dannes av det andre sylindriske avsnitt (9) i pressdelen (1). Ved hjelp av et pressverktøy med minst to pressbakker tilveiebringes det en uløsbar, tett rørpressforbindelse, idet under pressingen de nevnte pressbakker virker ikke bare på ringvulsten (4), men også på den der innlagte tetningsring, såvel som på det første sylindriske avsnitt (6) i pressdelen (1). Det foreslås at ringvulstens (4) bratte flanke mot det andre sylindriske avsnitt (9) går avrundet oppover i dette avsnitt (9) uten et spangsted, idet innerdiameteren (10) i det andre sylindriske avsnitt (9) er lik innerdiameteren (13) i det innskjøvne ledningsrør (3) innenfor en toleransebredde på pluss halve veggtykkelsen (15) til minus en ganger veggtykkelsen i det innskjøvne ledningsrør (3).BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a pipe press connection consisting of a pressing member (1) having at least one cross section (4) which bears a sealing ring (2), and one connected thereto, towards an insertion facing first cylindrical (6) and a the insertion end faces the second cylindrically shaped section (9), which second section (9) has a smaller inner diameter than the first section (6), thereby forming a stop, and a conduit (3)% smooth cut end after the insertion in the press member (1). ) receives abutment against the stop (12) formed by the second cylindrical section (9) in the press member (1). By means of a pressing tool with at least two press trays, an insoluble, dense tube press connection is provided, during which the said press trays act not only on the annulus (4), but also on the sealing ring therein, as well as on the first cylindrical section (6). in the press member (1). It is proposed that the steep edge of the annulus (4) towards the second cylindrical section (9) be rounded upwardly in this section (9) without a tapping point, the inner diameter (10) of the second cylindrical section (9) being equal to the inner diameter (13) the welded conduit (3) within a tolerance width of plus half the wall thickness (15) to less than once the wall thickness of the welded conduit (3).
