Imibandela Yokulethwa
Ngokuya ngezimo zokulethwa kanye nezinga le-PSL, i-X60 ingahlukaniswa ngale ndlela elandelayo:
I-PSL1: x60 noma i-L415;
I-PSL2: X60N, X60Q, X60M noma L415N, L415Q, L415M.
N: Ibonisa ukujwayela kokuqukethwe.Ngokushisisa insimbi ezingeni lokushisa elithile okulandelwa ukupholisa komoya.Ukwenza ngcono i-microstructure kanye nezakhiwo zemishini yensimbi nokwandisa ukuqina nokuvumelana kwayo.
Q: Imele ukucisha nokuthulisa.Ukuthulisa insimbi ngokuyifudumeza ezingeni elithile lokushisa, ukuyipholisa ngokushesha, bese uyifudumeza futhi ezingeni lokushisa eliphansi.Ukuthola ibhalansi yezakhiwo ezithile zemishini, njengamandla aphezulu kanye nokuqina.
M: Ibonisa ukwelashwa kwe-thermo-mechanical.Inhlanganisela yokwelashwa kokushisa nokwenza imishini yokuthuthukisa i-microstructure kanye nezakhiwo zensimbi.Kungenzeka ukwandisa amandla nokuqina kwensimbi ngenkathi ugcina izakhiwo ezinhle zokushisela.
I-API 5L X60 Manufacturing Process
Inqubo eyamukelekile yokukhiqiza ishubhu lensimbi le-X60
Uma uthola kunzima ukuqonda lezi zifinyezo, bheka ukuhlanganiswa kwethu kwama-athikiliizifinyezo ezivamile amapayipi ensimbi.
Izinzuzo ze-SAWL (LSAW)
Uma udinga ububanzi obukhulu obukhulu bodonga lwepayipi yensimbi, ukukhetha kokuqalaSAWL (I-LSAW) ipayipi lensimbi.Ipayipi lensimbi le-LSAW lingakhiqizwa ngobukhulu obufinyelela ku-1500mm ububanzi no-80mm odongeni obukhulu, elikwazi ngokugcwele ukuhlangabezana nezidingo zamapayipi amabanga amade amaphrojekthi amakhulu.
Ngaphezu kwalokho, ngesikhathi senqubo yokukhiqiza, ipayipi lensimbi le-LSAW lamukela ukushisela kwe-arc okunezinhlangothi ezimbili (I-DSAW) inqubo, eqinisekisa ikhwalithi ye-weld seam.
I-API 5L X60 Chemical Composition
I-PSL1 ilula kakhulu kune-PSL2 mayelana nokwakheka kwamakhemikhali, izakhiwo zemishini, nezinye izidingo.
Lokhu kungenxa yokuthiI-PSL1imele izinga elijwayelekile lekhwalithi yepayipi lensimbi yepayipi, ngenkathiI-PSL2ingabonwa njengenguqulo ethuthukisiwe ye-PSL1, enikeza ukucaciswa okuthuthuke kakhulu nokulawula ikhwalithi okuqinile.
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:
CEpcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Ngemikhiqizo yepayipi yensimbi ye-PSL2 ehlaziywe ngeokuqukethwe kwekhabhoni > 0.12%, okulingana nekhabhoni CEllwingabalwa kusetshenziswa ifomula engezansi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Ukwakheka Kwekhemikhali no-t ＞ 25.0 mm (0.984 in.)
Izonqunywa ngokuxoxisana futhi iguqulelwe ekubunjweni okufanele ngokusekelwe ezidingweni zokwakheka kwamakhemikhali ngenhla.

Qaphela: Izidingo zichazwe kabanzi esigabeni seMechanical Properties sokuthiI-API 5L X52, engabukwa ngokuchofoza ifonti eluhlaza okwesibhakabhaka uma unentshisekelo.
Okunye Ukuhlolwa Kwemishini
Uhlelo olulandelayo lokuhlolaisebenza ezinhlotsheni zamapayipi ensimbi ye-SAW kuphela.
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.
Izinto zokuhlola namafrikhwensi okuhlola ezinye izinhlobo zamapayipi zingatholakala kuThebula 17 no-18 wezinga le-API 5L.
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 lensimbifuthi ngeke kube khona ukuvuza okuvela kumshini wokushisela noma wepayipi ngesikhathi sokuhlolwa.
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
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.
