Abstract

Et sammenføyd rør (1) er fremstilt med væskefasediffusjonsprosessen, hvor rørendene til rør (1) som skal sammenføyes er plassert butt i butt mot hverandre med et innsatsmateriale (3) med lavere smeltepunkt enn rørmaterialet plassert mellom seg, og tykkelsen er økt på en slik måte at den utvendige diameter av det buttskjøtede parti er utvidet og den innvendige diameter av dette er redusert. En fremgangsmåte til sammenføying av rør (I) hvor rørender av rør (I) er plassert butt-i- butt mot hverandre med et innsatsmateriale (3) med lavere smeltepunkt enn rørmaterialet plassert mellom seg, og partiene som er plassert butt-i-butt mot hverandre blir oppvarmet til og holdt ved en holdetemperatur som er høyere enn innsats- materialets smeltepunkt, hvor innsatsmaterialet i væskefase diffunderer inn i rørmaterialet, er kjennetegnet ved at, påføringen av et trykk i rørets aksiell retning på de ovennevnte partier som er plassert butt-i-butt for å øke tykkelsen av det buttskjøtede parti, hvilket trykk er i stand til plastisk å deforme partiene som er plasssert butt i butt, startet for å øke tykkelsen av det buttskjøtede parti på et tidspunkt når temperaturen i rørets utvendige overflate i de ovennenvte partier som er plassert butt i butt når en verdi som ikke er lavere enn rørmaterialcts kritiske temperatur A, og ikke høyere enn holdetemperaturen i prosessen for heving av temperaturen i rørmaterialet, blir startet.
