I-API 5L X65 Ukuhlelwa
Ngokuya ngezinga le-PSL nesimo sokulethwa, i-X65 ingahlukaniswa kanje:
I-PSL1: X65 (L450);
PSL2: X65Q (L450Q) kanye ne-X65M (L450M);
Ukuze ubhekane nezimo ezinzima ze-offshore (O) kanye nezindawo zesevisi emuncu (S), izinga le-API 5L PSL2 linezidingo ezikhethekile zazo zombili izindawo.Lezi zidingo ziboniswa ngokwengezwa kwencwadi ethile ebangeni lepayipi.
Ipayipi le-PSL2 lezinsizakalo zasolwandle:I-X65QO (l450QO) noma i-X65MO (L450MO);
Ipayipi le-PSL2 lenkonzo emuncu:I-X65QS (L450QS) noma i-X65MS (L450MS).
Imibandela Yokulethwa
Incazelo ye-Q kanye ne-M
NgobaSAW(I-Arc Ehlanganisiwe Eshiselwe) nomaINKOMAZI(I-Combination Welded Pipe), i-Q kanye ne-M esimweni sokulethwa se-API 5L PSL2 zihambisana nezinqubo zokukhiqiza ezilandelayo ngokulandelana kwazo.
I-API 5L X65 Inqubo Yokukhiqiza
X65amapayipi angakhiqizwa ngezinqubo ezahlukahlukene zokukhiqiza ukuze avumelane nezinhlelo eziningi zokusebenza zobunjiniyela.
SAWL(LSAW) ilungele ukukhiqizwa kwamashubhu anobubanzi obukhulu, anodonga oluwugqinsi anobubanzi obungaphezu kuka-660 mm, ikakhulukazi endaweni yamanani lapho inikeza inzuzo yezindleko ngaphezu kwamashubhu angenamthungo.
Izinhlobo ze-Pipe End ye-API 5L X65
PSL1 Steel Pipe End: Belled end noma Plain end;
PSL2 Steel Pipe End: Plain end;
Ukuze uthole iziphetho zepayipi elingenalutholezi zidingo ezilandelayo kufanele zilandelwe:
Ubuso bokugcina buka-t ≤ 3.2 mm (0.125 in) ipayipi elingenalutho elingenalutho lizosikwa isikwele.
Amashubhu angenalutho ano-t > 3.2 mm (0.125 in) azovulwa ukuze ashiselwe.I-engeli ye-bevel kufanele ibe ngu-30-35 ° futhi ububanzi bobuso bempande ye-bevel kufanele bube ngu-0.8 - 2.4 mm (0.031 - 0.093 in).
I-API 5L X65 Chemical Composition
Ukwakheka kwamakhemikhali kwe-PSL1 ne-PSL2 ipayipi lensimbi t > 25.0 mm (0.984 in) kuzonqunywa ngesivumelwano.
Ukwakheka Kwekhemikhali ye-PSL 1 Ipayipi eno-t ≤ 25.0 mm (0.984 in.)
Ukwakheka Kwekhemikhali ye-PSL 2 Ipayipi eno-t ≤ 25.0 mm (0.984 in.)
Ngemikhiqizo yepayipi yensimbi ye-PSL2 ehlaziywe ngeokuqukethwe kwekhabhoni okungu-≤0.12%, okulingana nekhabhoni CEpcmingabalwa kusetshenziswa ifomula elandelayo:

Qaphela: Izidingo zichazwe ngokuningiliziwe kuI-API 5L X52, engabukwa uma kudingeka.
Okunye Ukuhlolwa Kwemishini
Uhlelo olulandelayo lokuhlola lusebenza kuIzinhlobo zamapayipi e-SAW.Ukuze uthole ezinye izinhlobo zamapayipi, bheka Amathebula 17 no-18 we-API 5L.
Ukuhlolwa kokugoba komhlahlandlela we-weld;
Ukuhlolwa kokuqina kwepayipi elihlanganisiwe elibandayo;
Ukuhlolwa kwe-Macro ye-seam ehlanganisiwe;
futhi kuphela ipayipi lensimbi le-PSL2: ukuhlolwa komthelela we-CVN nokuhlolwa kwe-DWT.
Ukuhlolwa kwe-Hydrostatic
Isikhathi Sokuhlola
Bonke osayizi bamashubhu ensimbi angenamthungo nashikelwe ano-D ≤ 457 mm (18 in.):isikhathi sokuhlola ≥ 5s;
Ipayipi lensimbi elishiselwe D > 457 mm (18 in.):isikhathi sokuhlola ≥ 10s.
Imvamisa Yokuhlola
Ipayipi ngalinye lensimbi.
Izingcindezi zokuhlola
I-hydrostatic test pressure P ye-aipayipi lensimbi elingenaluthoingabalwa ngokusebenzisa ifomula.
P = 2St/D
Singcindezi ye-hoop.inani lilingana namandla amancane ashiwo epayipi lensimbi xa iphesenti, ku-MPa (psi);
tubukhulu bodonga olucacisiwe, obuvezwa ngamamilimitha (amasentimitha);
Diwububanzi obushiwo bangaphandle, obuvezwa ngamamilimitha (amayintshi).
Ukuhlola Okungonakali
Okwamashubhu e-SAWizindlela ezimbili,UT(ukuhlolwa kwe-ultrasonic) nomaRT(ukuhlolwa kwe-radiographic), kuvame ukusetshenziswa.
ET(ukuhlolwa kwe-electromagnetic) akusebenzi kumashubhu e-SAW.
Izithungo ezishiselwe kumapayipi ashiselwe amabanga ≥ L210/A kanye nobubanzi ≥ 60.3 mm (2.375 in) azohlolwa ngendlela engonakalisi ukuze kubonakale ukujiya nobude obugcwele (100 %) njengoba kucacisiwe.
Ukuhlolwa kwe-UT okungabhubhisi
Ukuhlolwa kwe-RT okungabhubhisi
Ishadi Leshejuli Yepayipi le-API 5L
Amapayipi e-API 5L ahlukaniswe "Amashejuli" ahlukene ngokuya ngobukhulu obuhlukahlukene bodonga, njengokuthiIsheduli 20, Isheduli 40, Isheduli 80, njll. Lobu bukhulu bodonga buhambisana nezilinganiso ezihlukene zokucindezela kanye nezimo zohlelo lokusebenza.Lobu bukhulu bezindonga buhambisana nezilinganiso ezihlukene zokucindezela kanye nezimo zohlelo lokusebenza.
Ukuze kube lula ukubuka nokusebenzisa, sihlele uhlelo olufanele lwamafayela e-PDF.Ungakwazi ukulanda futhi ubuke la madokhumenti uma kudingeka.
Cacisa Ububanzi Bangaphandle Nokuqina Kodonga
Amanani amisiwe obubanzi obucacisiwe bangaphandle kanye nogqinsi olucacisiwe lwezindonga zepayipi lensimbi kunikezwaISO 4200futhiI-ASME B36.10M.
I-Dimensional Tolerances
Izidingo ze-API 5L zokubekezelelana kobukhulu zichazwe kabanziI-API 5L Ibanga B.Ukuze ugweme ukuphindaphinda, ungachofoza ifonti eluhlaza okwesibhakabhaka ukuze ubuke imininingwane efanele.
Izinhlelo zokusebenza
