Description

453 10 15 20 25 30 35 374 FIG 6 är en vy, motsvarande FIG 3, vilken visar en skarv med stötfog, och FIG 7 är en vy, motsvarande FIG 3, vilken visar en skarv vid ett enkelväggigt korrugerat rör.
I FIG 1 - 5 visas tillämpningen av sättet enligt uppfinningen på dubbelväggiga korrugerade rör A och B av den typ som består av en korrugerad yttervägg 10 och en relativt denna tunnare slät innervägg ll, var- vid båda väggarna är av ett smältbart plastmaterial.
Den korrugerade ytterväggen kan därvid utgöras medan den inre släta väggen kan utgöras av po- av po- lyeten, lyeten eller ett smältbart elastomert material, varvid det dubbelväggiga röret i det senare utförandet är re- för att väl lämpa sig till relining Yttervägg och i nnervägg lativt lättböjligt av markförlagda rörledningar. är på känt sätt förenade med varandra vid vågdalarna och bildar sålunda slutna ringformiga hålrum 12. De mot varandra vända rörändarna slutar med ett snitt ge- nom vågtopparna, så att det i vardera änden finns ett öppet ringformigt hålrum l3. I det öppna hålrummet i änden av röret A inlägges en vid tillförsel av energi expanderande ringkropp av i och för sig känt slag. vilken här har formen av en slangformig ring 14 med o- val tvärsektionsform. Ringen kan bestå exempelvis av ett PEX-rör, vilket har framställts med cirkulär tvär- sektionsform men sedan har uppvärmts och deformerats till oval form, varefter det fått svalna i denna form.
PEX-röret är omlindat med en värmetråd (inte visad), som är avsedd att anslutas till en strömkälla, och är utvändigt belagt med polyeten.
I det andra röret B införes en uppstyvande cy- lindrisk dorn 15 med fasade ändkanter 16 och med ett runtomgående snett spår 17 i utsidan för upptagning av ändpartiet av den tunna och relativt mjuka innerväggen ll hos röret B, såsom visas i FIG 2. 10 15 20 25 30 35 453 374 Sedan rörändarna arrangerats på detta sätt, föres de samman, varvid dornen i den yttre änden bildar en ramp 18 för att lyfta röret A något, när det skjutes in på dornen, så att detta rörs yttervägg kommer utan- på det andra rörets B yttervägg, såsom visas i FIG 3.
Domen 15 förøkjutcß axiellt för att komma att ligga i sådant läge, att den överbryggar skarven mellan rören, och därvid erhålles också överlappning mellan inner- väggarna, när det i spåret upptagna ändpartiet av rö- rets B innervägg strykes ut ur spåret vid dornens för- skjutning. En yttre fixtur 19 bringas att omsluta rö- ren i skarvområdet för att tillsamman med den som en inre fixtur fungerande dornen hålla den åstadkomma ö- verlappsfogen i läge under det nu följande svetsnings- tempot. Eventuellt kan dornen 15 vara expanderbar dels för att den skall kunna pressas mot rören och dels för att den skall kunna dragas ihop och därigenom lättare skall kunna föras in i och ut ur rören.
Svetsningstempot består i att värmetråden anslu- tes till en strömkälla för uppvärmning av ringen 14, som under uppvärmningen strävar att återtaga sin ur- sprungliga cirkulära form på grund av s k minnesef- fekt. Samtidigt. bringas plastmaterialet i ytterväggar och innerväggar samt plastmaterialet utanpå ringen att smälta, så att det bildas en homogen övergång mellan rören med ringen fastsvetsad vid väggarna. Fixtur och dorn kan avlägsnas, och den färdiga skarven har nu det utseende som framgår av FIG 5.
Om det är fråga om den mera allmänt förekommande rörtypen, vid vilken yttervägg och innervägg båda be- står av polyeten och har ungefärligen samma tjocklek, kan skarven anordnas som stumfog enligt FIG 6. Rörän- darna hopsvetsas då vid de mot varandra ansatta ring- formiga ändytorna på yttervägg och innervägg men svet- sas också fast vid ringen 14. Under inverkan av det 453 374 10 15 20 25 30 35 tryck som utövas av ringen 14, när den expanderar, kan materialet i ytterväggen bli tunt, och för att kompen- sera för detta kan en remsa av polyeten före svets- ningen och ansättningen av den yttre fixturen lindas omkring rören på dessas utsida i skarvområdet. observeras, att det genom Det skall särskilt tillämpning av sättet enligt uppfinningen erhålles en Man behöver sålunda inte slät innerröret. räkna med invändiga utsprång i skarvområdet, som skul- insida på le kunna störa flödet genom rören.
Sättet enligt uppfinningen kan tillämpas även vid enkelväggiga rör med korrugerad vägg, exempelvis vär- mekulvertrör, vilka innefattar en yttre korrugerad po- värmeisolerande lyetenmantel lO, vilken omsluter ett skumplastmaterial 20, vanligen skummad polyeten, tvär- bunden polyeten eller polyuretan, såsom är visat i FIG 7. I detta fall avlägsnas skumplastmaterialet i rörän- darna, för att en cylindrisk polyetenhylsa 21 skall kunna läggas in i rörändarna för att överlappa skarven mellan dem. Denna hylsa bildar stöd för de korrugerade mantelrörens ändar, och ringen 15 kommer under svets- ningsmomentet att fästa vid såväl hylsan som mantelrö- och tillförlitlig ren, varigenom erhålles en styv skarv.
