Description
Sadašnji izum se odnosi na postupak spajanja dvije armirane cijevi od termoplastičnog materijala koje imaju isti promjer.
Cjevovodi za transportiranje fluida po gradovima su načinjeni od cijevi malog promjera, reda veličine 80 do 200 mm. Cijevi su često načinjene od armiranog termoplastičnog materijala.
Da bi se osigurala neprekinutost cjevovoda, dva kraja takvih armiranih cijevi od termoplastičnog materijala moraju često biti spojena na nepropustan način na mjestu instaliranja.
U stanju tehnike je dobro poznata upotreba metalnih spojnica za spajanje dva kraja cijevi kako bi se osiguralo da cjevovod ima istu otpornost na vanjska naprezanja u predjelu spoja i na glavnom dijelu cijevi.
Ove metalne spojnice su slabe u smislu aksijalnih opterećenja i ne osiguravaju čvrsto zatvaranje spojeva. Kraj cijevi se često odvaja od spojnice kada je cjevovod pod pritiskom.
Predmet izuma je prijedlog postupka spajanja dvije armirane cijevi od termoplastičnog materijala, koji je jednostavan za upotrebu i osigurava zadovoljavajuću čvrstoću cjevovoda u predjelu spajanja kao i čvrsto zatvaranje i sprječava bilo kakvo odvajanje pod utjecajem aksijalnih opterećenja.
U tu svrhu se izum sastoji od postupka za spajanje dvije armirane cijevi od termoplastičnog materijala koje imaju isti promjer, karakterističnog po tome da su krajevi dvije cijevi najprije čeono zavareni duž perifernog spoja i, nakon obavljenog zavarivanja, postavljena je armirana vanjska košuljica preko većeg dijela duljine perifernog spoja, koja košuljica se proteže na obje strane spoja preko krajnjih sekcija obiju cijevi, i tada se vanjska košuljica zagrijava i radijalno pritišće sve dok vanjska košuljica i krajnje sekcije dvije cijevi međusobno ne penetriraju.
Posebno ostvarenje postupka ima jednu ili više sljedećih karakteristika:
- radijalni pritisak se primjenjuje na vanjsku košuljicu sve dok armirajuće strukture, koje ojačavaju dvije cijevi i vanjsku košuljicu, ne dođu u kontakt prilikom međusobnog penetriranja vanjske košuljice i krajnjih sekcija dvije cijevi;
- vanjska košuljica sadržava cjevasti cilindar koji određuje zatvorenu konturu koja ovija krajnje sekcije cijevi;
- vanjska košuljica sadržava uzdužno rascijepljen cilindar koji ovija krajnje sekcije cijevi;
- obodna duljina cilindra je takva da cilindar određuje zatvorenu konturu oko dvije cijevi nakon međusobnog penetriranja košuljice i krajnjih sekcija dvije cijevi;
- vanjska košuljica sadržava sastavljene niti koje uključuju neprekinute staklene filamente i neprekinute filamente od organskog termoplastičnog materijala, koji filamenti su prilagođeni da tvore mrežu;
- organski termoplastični materijal je polietilen;
- sastavljene niti od neprekinutih staklenih filamenata i neprekinutih filamenata od organskog termoplastičnog materijala su postavljene unakrsno;
- sastavljene niti su namotane spiralno i definiraju kutove od bitno +55° ili -55° prema osi vanjske košuljice;
- sastavljene niti definiraju kutove od bitno 0° i 90° prema osi vanjske košuljice;
- neprekinuti stakleni filamenti i neprekinuti filamenti od organskog termoplastičnog materijala su isprepleteni;
- aksijalna duljina vanjske košuljice je u opsegu od 0,5 puta do 3 puta veća od promjera cijevi koje se spajaju;
- dva kraja cijevi su čeono zavareni bez materijala za punjenje, naročito zrcalnim spajanjem; i
- zaštitni rukavac je postavljen preko cijele površine vanjske košuljice nakon što je ova postavljena.
Izum će biti bolje razumljiv nakon čitanja sljedećeg opisa koji je dan samo kao primjer i poziva se na crteže, u kojima:
- slika 1 prikazuje izgled poprečnog presjeka armirane cijevi od termoplastičnog materijala,

Cijev za prenošenje fluida prikazana na slici 1 ima, na primjer, unutarnji promjer od 180 mm. Cijev je sastavljena cijev načinjena od armiranog termoplastičnog materijala.
Cijev ima unutarnji sloj 12 od ekstrudiranog polietilena visoke gustoće. Unutarnji sloj je, na primjer, debeo 8 mm. Unutarnji sloj 12 je prekriven armiranim slojem 14, načinjenim od neprekinutih staklenih filamenata i neprekinutih filamenata od termoplastičnog organskog materijala, takvog kao što je polietilen visoke gustoće, koji može biti iste vrste kao i onaj koji tvori unutarnji sloj 12.
Za izradu ovog sloja kombinirani su neprekinuti stakleni filamenti i neprekinuti filamenti od organskog termoplastičnog materijala, kako bi tvorili sastavljene niti u kojima su dva tipa filamenata prisno spojena. Takve složene niti su izrađene postupkom opisanim u dokumentu EP-0.367.661, WO-98/01751 ili EP-0,599.695. Sastavljene niti su namotane spiralno na unakrstan način. U odnosu na uzdužnu os cijevi, niti je prolaze pod kutom od ±55°, ili pod kutom od 0° i 90° u odnosu na smjer proizvodnje cijevi. Složene niti koje su namotane na taj način, povezane su zagrijavanjem do temperature više od točke taljenja filamenata od organskog termoplastičnog materijala, kako bi stvorile kontinuirani sloj čiji odnos nepopunjenosti je povoljno manji od 0,5% po volumenu, i poželjno manji od 0,2%.
Neprekinuti stakleni filamenti 14A su tada položeni u organski termoplastični materijal 14B. Unakrsni neprekinuti stakleni filamenti ojačavaju materijal koji tvori cijev. Ukupna debljina armiranog sloja 14 je, na primjer, 2 mm.
Slika 2 prikazuje dvije sekcije cijevi 18A, 18B tipa prikazanog na slici 1. Ove cijevi trebaju biti spojene primjenom postupka prema ovom izumu.
U tu svrhu su krajevi dvije cijevi 18A, 18B postavljeni licem na lice na zajedničkoj osi za obje cijevi.
Krajevi cijevi su najprije čeono zavareni bez materijala ispune. Zavarivanje je povoljno izvedeno postupkom zrcalnog zavarivanja.
U tu svrhu, i kako je prikazano na slici 2, rotirajući je disk 20, sa svojom osi 22 paralelnom s osima dvije cijevi, smješten između prstenastih krajnjih lica cijevi 24, 26. Lica 24, 26 su održavana u kontaktu s nasuprotnim licima diska 20, koji rotira oko osi 22. To zagrijava lica krajeva cijevi do zadovoljavajuće temperature koja ih omekšava do stanja blizu taljenja.
Disk 20 je tada uklonjen i dva kraja cijevi 18A, 18B se pomaknu jedan prema drugom i aksijalno se pritisnu jedan uz drugog. Zatim se oni hlade.
Kao što je prikazano na slici 3, unutarnji slojevi 12, međuslojevi 14 i vanjski slojevi 16 dvije cijevi 18A, 18B su međusobno zavareni duž perifernog spojnog zavara 28. U području spojnog zavara 28, cijev ima vanjsko izbočenje 28A i interno izbočenje 28B, koja nastaju zbog međusobnog pritiskanja dvaju omekšanih krajeva cijevi.
Slika 4 je grafičko predstavljanje zavarenog spoja dobivenog na ovaj način.
Ispitivanje zavarenog spoja pokazuje da je spoj nepropustan i da staklena vlakna, koja su sadržana u armiranom sloju 14, ostaju uložena u polietilenu visoke gustoće bez stvaranja bilo kakvog prolaza za tekućine. Posebno, krajevi armiranog sloja 14 su zavinuti i prekriveni. Ipak, oni ne strše kroz vanjski sloj 16, ma koliko on bio tanak u predjelu zavarenog spoja 28.
Nakon izrade zavarenog spoja 28, i kao što je prikazano na slici 5, armirana vanjska košuljica 30, načinjena od armiranog termoplastičnog materijala, postavljena je oko spojnog zavara 28. Njena aksijalna dužina je dovoljna da obuhvati obje strane zavarenog spoja 28 preko krajnjih sekcija spojenih cijevi 18A, 18B.
Vanjska košuljica 30 je izrađena od uzdužno razrezanog cilindra koji omata dvije krajnje sekcije cijevi. Njena aksijalna dužina je u opsegu od 0,5 puta do 3 puta veća od vanjskog promjera cijevi koje trebaju biti spojene.
Cilindar 30 u početku povoljno sadržava sastavljene niti načinjene od neprekinutih staklenih filamenata 30A i neprekinutih filamenata 30B od organskog termoplastičnog materijala, kao što je polietilen visoke gustoće. Sastavljene niti su spojene da čine mrežu.
U prvom ostvarenju postupka, sastavljene niti u cilindru 30, koje sadržavaju neprekinute staklene filamente i neprekinute filamente od organskog termoplastičnog materijala, namotane su spiralno na unakrstan način. Niti prolaze jedna prema drugoj, na primjer, pod kutom u opsegu od 50° do 55° prema osi cilindra 30. Sastavljene niti povoljno prolaze pod kutom od 0° i 90° u odnosu na os cilindra. To osigurava povećano aksijalno ojačanje nakon što je montiran cilindar. Struktura vanjske košuljice 30 bitno je usklađena sa strukturom armiranog sloja 14 cijevi 18A, 18B prije zagrijavanja.
Kao alternativa, niti su isprepletene.
Sastavljene niti su povoljno načinjene svaka u obliku od 800 staklenih filamenata i 800 polietilenskih filamenata prisno pomiješanih jednih s drugima. TWINTEX-ove sastavljene niti, prodavane kao VERTOTEX, sadržavaju 60% stakla i 40% polietilena.
Za stavljanje košuljice 30 primijenjene su dvije grijaće poluljuske 32, 34 na vanjskoj površini košuljice. One su projektirane da zagrijavaju vanjsku površinu košuljice 30 i da je radijalno pritišću na zavareni spoj 28 i na krajnje sekcije spojenih cijevi 18A, 18B. Pritisak od 1 bara daje najbolje rezultate.
Grijaće poluljuske 32, 34 stišću radijalno vanjsku košuljicu u smjeru strjelice F i istovremeno je griju na temperaturu iznad točke taljenja organskog termoplastičnog materijala koji tvori filamente 30B. Njihovo djelovanje se održava sve dok vanjska košuljica 30 i krajnje sekcije cijevi 18A, 18B međusobno ne penetriraju, kako je prikazano na slici 6. Radijalno stezanje i grijanje se primjenjuju sve dok se filamenti 30B ne rastale, a stakleni filamenti 30A i 14A, koji tvore armaturna vlakna vanjske košuljice 30, i međusloj 16 ne dođu u kontakt.
Nakon taljenja, filamenti 30B stvaraju povezani materijal 30C, kojim su stakleni filamenti 30A presvučeni ili u njega uključeni.
Kada se grijaće ljuske uklone, i nakon hlađenja, stakleni filamenti 30A spojenih cijevi 18A, 18B su neprekinuti u predjelu spoja, ojačavajući cjevovod aksijalno i po obodu.
Obodna dužina cilindra, koji oblikuje vanjsku košuljicu 30, povoljno je odabrana tako da, nakon što međusobno penetrira s krajnjim sekcijama dvije cijevi, lica uzdužnih krajeva cilindra su stično ili djelomično preklopno spojena, tako da je rezultat taj da je vanjska košuljica 30 po obodu kontinuirana.
Zaštitni rukavac 36 (vidi sliku 7) je postavljen po cijeloj površini vanjske košuljice 30 s namjerom da zaštiti područje spoja, a posebno sve vanjske površine košuljice 30, od fizičkih i kemijskih utjecaja tla. Zaštitni rukavac 36 je povoljno načinjen od materijala koji se zagrijavanjem steže, takav kao što je polietilen visoke gustoće, koji može biti iste kvalitete kao onaj unutarnjeg sloja 12.
Vanjska košuljica 30 je povoljno montirana i radijalno stisnuta na zavareni kraj sekcija spojenih cijevi prije nego što se zavarni spoj 28 ohladi.
Vanjska košuljica 30 može biti montirana na sobnoj temperaturi i zagrijana u isto vrijeme kad je radijalno stisnuta na spojni predio dvije cijevi.
Alternativno, vanjska košuljica 30 se zagrijava odvojeno od cijevi i tada se montira oko njih pri temperaturi koja joj omogućava da bude radijalno stegnuta kada se pritišće pomoću dvije polučahure.
U ostvarenju koje je različito od izuma, cilindar koji oblikuje vanjsku košuljicu je cijev koja ima prije montaže zatvorenu konturu.
S postupkom kao što je gore opisano, spoj između dvije cijevi očevidno ima čvrstoću sličnu onoj kakvu ima glavni dio cijevi, jer su stakleni filamenti koji predstavljaju armaturu neprekinuti u sekciji u kojoj je spoj.
