I-API 5L X65 (L450)iyipayipi lensimbi yekhabhoni eliphakathi nendawo kuya kwelezinga eliphezulu le-API 5L, eliqanjwe nge-y yalo encaneAmandla ensimu angu-65,300 psi (450 MPa).
Ngokuvamile yakhelwe ukubhekana nezingcindezi ezinkulu kanye nezimo ezinzima, ipayipi lensimbi le-X65 lifaneleka kakhulu kumapayipi kawoyela negesi lapho kudingeka khona ukuqina okuphezulu nokuthembeka. Ngaphezu kwalokho, izakhiwo zalo ezinhle kakhulu zemishini kanye nokumelana nokugqwala kwenza libe yindawo ekahle yokusetshenziswa kumapayipi angaphansi kolwandle kanye nasezindaweni zezimboni ezigqwala kakhulu.
Insimbi yeBotopungumkhiqizi ochwepheshe wepayipi lensimbi le-LSAW elingaphansi kodonga olukhulu olunobubanzi obuphindwe kabili eliseShayina.

Ukuhlukaniswa kwe-API 5L X65
Kuye ngezinga le-PSL kanye nesimo sokulethwa, i-X65 ingahlukaniswa kanje:
I-PSL1: X65 (L450);
I-PSL2: X65Q (L450Q) kanye ne-X65M (L450M);
Ukuze kuhlangatshezwane nezimo ezinzima zezindawo ezisogwini lolwandle (O) kanye nezindawo zesevisi emuncu (S), indinganiso ye-API 5L PSL2 inezidingo ezikhethekile kuzo zombili izindawo. Lezi zidingo ziboniswa ngokungezwa kohlamvu oluthile ebangeni lepayipi.
Izinsizakalo zasogwini ipayipi le-PSL2:I-X65QO (l450QO) noma i-X65MO (L450MO);
Ipayipi le-PSL2 lensizakalo emuncu:I-X65QS (L450QS) noma i-X65MS (L450MS).
Izimo Zokulethwa
Incazelo ka-Q no-M
NgobaI-SAW(I-Arc Welded Ecmerged) nomaINKOMO(Ipayipi Elihlanganisiwe Elihlanganisiwe), i-Q kanye ne-M esimweni sokulethwa kwe-API 5L PSL2 zihambisana nezinqubo zokukhiqiza ezilandelayo ngokulandelana.
Inqubo Yokukhiqiza ye-API 5L X65
I-X65Amapayipi angakhiqizwa ngezinqubo ezahlukahlukene zokukhiqiza ukuze avumelane nezinhlelo zokusebenza eziningi zobunjiniyela.
I-SAWL(LSAW) ilungele ukukhiqizwa kwamashubhu amakhulu, anodonga olujiyile anobubanzi obungaphezu kuka-660 mm, ikakhulukazi lapho intengo ihlinzeka khona ngenzuzo yezindleko ngaphezu kwamashubhu angenamthungo.
I-LSAWkuvame ukubizwa ngokuthiI-DSAWngenxa yenqubo yokushisela enezinhlangothi ezimbili esetshenziswa enqubweni yokushisela. Kubalulekile ukuqaphela ukuthi i-DSAW ibhekisela enkambisweni yokushisela futhi ayibhekiseli ngqo ekumeni noma ekuqondisweni kwe-weld. Kungaba umthungo oqondile noma umthungo ojikelezayo.
Izinhlobo Zokuphela Kwepayipi ze-API 5L X65
Isiphelo Sepayipi Lensimbi le-PSL1: Isiphelo esine-bell noma isiphelo esingenalutho;
Isiphelo Sepayipi Lensimbi le-PSL2: Isiphetho esilula;
Ngeziphetho zamapayipi alulalezi zidingo ezilandelayo kufanele zilandelwe:
Ubuso bokugcina bepayipi elingenalutho elingu-t ≤ 3.2 mm (0.125 in) kufanele bube yisikwele.
Amashubhu angenalutho ano-t > 3.2 mm (0.125 in) kufanele abekwe eceleni ukuze kushiselwe. I-engeli ye-bevel kufanele ibe ngu-30-35° kanti ububanzi bobuso bempande ye-bevel kufanele bube ngu-0.8 - 2.4 mm (0.031 - 0.093 in).
Ukwakheka Kwamakhemikhali kwe-API 5L X65
Ukwakheka kwamakhemikhali kwepayipi lensimbi le-PSL1 ne-PSL2 elingu-t > 25.0 mm (0.984 in) kufanele kunqunywe ngesivumelwano.
Ukwakheka Kwamakhemikhali Kwepayipi Le-PSL 1 elino-t ≤ 25.0 mm (0.984 in.)
Ukwakheka Kwamakhemikhali Kwepayipi Le-PSL 2 elino-t ≤ 25.0 mm (0.984 in.)
Kwemikhiqizo yepayipi lensimbi ye-PSL2 ehlaziywe ngeokuqukethwe kwekhabhoni okungu-≤0.12%, i-CE elingana nekhabhonii-pcmingabalwa kusetshenziswa ifomula elandelayo:
CEi-pcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Kwemikhiqizo yepayipi lensimbi ye-PSL2 ehlaziywe ngeokuqukethwe kwekhabhoni > 0.12%, i-CE elingana nekhabhonillwingabalwa kusetshenziswa ifomula engezansi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Izakhiwo Zemishini ze-API 5L X65
Izakhiwo Zokunamathela
Ukuhlolwa kokuqina kuvumela ukunqunywa kwezakhiwo ezibalulekile zezinto ze-X65, okuhlanganisaamandla okukhiqiza, amandla okudonsa, futhiukunwebeka.
Izakhiwo Zokunamathela ze-PSL1 X65
Izakhiwo Zokunamathela ze-PSL2 X65
Inothi: Izidingo zichazwe kabanzi ku-I-API 5L X52, okungabukwa uma kudingeka.
Ezinye Izivivinyo Zemishini
Uhlelo lokuhlola olulandelayo lusebenza kuIzinhlobo zamapayipi e-SAWUkuze uthole ezinye izinhlobo zamapayipi, bheka Amathebula 17 no-18 e-API 5L.
Ukuhlolwa kokugoba komhlahlandlela wokushisela;
Ukuhlolwa kobulukhuni bepayipi elihlanganisiwe elenziwe ngobandayo;
Ukuhlolwa okukhulu komthungo ohlanganisiwe;
futhi kuphela ngepayipi lensimbi le-PSL2: ukuhlolwa komthelela we-CVN kanye nokuhlolwa kwe-DWT.
Ukuhlolwa Kwamanzi
Isikhathi Sokuhlolwa
Bonke osayizi bamashubhu ensimbi angenamthungo nashibiliwe ano-D ≤ 457 mm (18 in.):isikhathi sokuhlola ≥ 5s;
Ipayipi lensimbi elihlanganisiwe D > 457 mm (18 in.):isikhathi sokuhlola ≥ 10s.
Imvamisa Yokuhlola
Ipayipi ngalinye lensimbi.
Izingcindezi zokuhlola
Ingcindezi yokuhlola ye-hydrostatic P ye-aipayipi lensimbi elingenasicikungabalwa ngokusebenzisa ifomula.
P = 2St/D
Sukucindezeleka kwe-hoop. inani lilingana namandla amancane okukhiqiza acacisiwe ephesenti le-xa lepayipi lensimbi, ku-MPa (psi);
tukujiya kodonga okucacisiwe, okuvezwa ngamamilimitha (amasentimitha);
Dububanzi obungaphandle obucacisiwe, obuvezwa ngamamilimitha (amasentimitha).
Ukuhlolwa Okungonakalisi
Kwamashubhu e-SAW, izindlela ezimbili,UT(ukuhlolwa kwe-ultrasonic) nomaRT(ukuhlolwa kwe-radiography), kuvame ukusetshenziswa.
ET(ukuhlolwa kwe-electromagnetic) akusebenzi kumashubhu e-SAW.
Izithungo ezihlanganisiwe kumapayipi ahlanganisiwe asezingeni ≥ L210/A kanye nobubanzi ≥ 60.3 mm (2.375 in) kufanele zihlolwe ngaphandle kokubhujiswa ukuze zibone ukujiya nobude obugcwele (100%) njengoba kuchaziwe.
Ukuhlolwa kwe-UT okungonakalisi
Ukuhlolwa kwe-RT okungonakalisi
Ishadi Leshejuli Yamapayipi e-API 5L
