I-API 5L X60 (L415) iyipayipi lomugqaenamandla okukhiqiza okungenani angu-60,200 (415 MPa) okusetshenziswa ezinhlelweni zokuthutha amapayipi embonini kawoyela negesi.
I-X60kungaba yizinhlobo eziningi zamapayipi ensimbi ahlanganisiwe angenamthungo, ngokuvamile i-LSAW (SAWL), i-SSAW (SAWH), kanye ne-ERW.
Ngenxa yamandla ayo aphezulu nokuqina kwayo, ipayipi le-X60 livame ukusetshenziselwa amapayipi adlula isifunda amabanga amade noma imisebenzi yokuthutha ezindaweni eziyinkimbinkimbi nakwezinye izindawo ezidinga amandla.
Insimbi yeBotopungumkhiqizi ochwepheshe wepayipi lensimbi le-LSAW elingaphansi kodonga olukhulu olunobubanzi obuphindwe kabili eliseShayina.

Izimo Zokulethwa
Kuye ngezimo zokulethwa kanye nezinga le-PSL, i-X60 ingahlukaniswa kanje:
I-PSL1: x60 noma i-L415;
I-PSL2: X60N, X60Q, X60M noma i-L415N, L415Q, L415M.
N: Kubonisa ukwenziwa kwezinto zibe zijwayelekile. Ngokufudumeza insimbi ekushiseni okuthile kulandelwe ukupholisa komoya. Ukuthuthukisa isakhiwo esincane kanye nezakhiwo zensimbi kanye nokwandisa ukuqina kwayo kanye nokuvumelana kwayo.
Q: Kumelela ukucima kanye nokushisa. Ukushisa insimbi ngokuyifudumeza ifike ezingeni lokushisa elithile, uyipholise ngokushesha, bese uyifudumeza futhi ifike ezingeni lokushisa eliphansi. Ukuze kutholakale ibhalansi yezakhiwo ezithile zemishini, njengamandla aphezulu kanye nokuqina.
M: Kubonisa ukwelashwa kwe-thermo-mechanical. Inhlanganisela yokwelashwa kokushisa kanye nomshini wokulungisa ukuze kuthuthukiswe isakhiwo esincane kanye nezakhiwo zensimbi. Kungenzeka ukwandisa amandla nokuqina kwensimbi ngenkathi kugcinwa izakhiwo ezinhle zokushisela.
Inqubo Yokukhiqiza ye-API 5L X60
Inqubo yokukhiqiza amashubhu ensimbi eyamukelekayo ye-X60
Uma ukuthola kunzima ukuqonda lezi zifinyezo, hlola ukuhlanganiswa kwethu kwezihloko eziphatheleneizifinyezo ezivamile zamapayipi ensimbi.
Izinzuzo ze-SAWL (LSAW)
Uma udinga ipayipi lensimbi eludongeni elikhulu elinobubanzi obukhulu, ukukhetha kokuqala yilokhuI-SAWL (I-LSAW) ipayipi lensimbi. Ipayipi lensimbi le-LSAW lingakhiqizwa ngobukhulu obufika ku-1500mm ububanzi kanye nobukhulu bodonga obungu-80mm, obukwazi ngokugcwele ukuhlangabezana nezidingo zamapayipi amabanga amade kumaphrojekthi amakhulu.
Ngaphezu kwalokho, ngesikhathi senqubo yokukhiqiza, ipayipi lensimbi le-LSAW lisebenzisa ukushisela kwe-arc okucwiliswe emaceleni amabili (I-DSAW) inqubo, eqinisekisa ikhwalithi yomthungo wokushisela.
Ukwakheka Kwamakhemikhali kwe-API 5L X60
I-PSL1 ilula kakhulu kune-PSL2 ngokwendlela yokwakheka kwamakhemikhali, izakhiwo zemishini, kanye nezinye izidingo.
Lokhu kungenxa yokuthiI-PSL1imelela izinga elijwayelekile lekhwalithi yepayipi lensimbi yamapayipi, kuyilaphoI-PSL2kungabonakala njengenguqulo ethuthukisiwe ye-PSL1, enikeza imininingwane ethuthukisiwe kanye nokulawulwa kwekhwalithi okuqinile.
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
Ukwakheka Kwamakhemikhali okune-t ＞ 25.0 mm (0.984 in.)
Kuzonqunywa ngokuxoxisana futhi kuguqulwe kube ukwakheka okufanele ngokusekelwe ezidingweni zokwakheka kwamakhemikhali ezingenhla.
Izakhiwo Zemishini ze-API 5L X60
Izakhiwo Zokunamathela
Ukuhlolwa kokudonsa kuyisimiso esibalulekile sokuhlola izakhiwo zemishini zamashubhu ensimbi. Lokhu kuhlolwa kuvumela ukunqunywa kwamapharamitha abalulekile ezinto, okuhlanganisaamandla okukhiqiza, amandla okudonsa, kanye no-eubude.
Izakhiwo Zokunamathela ze-PSL1 X60
Izakhiwo Zokunamathela ze-PSL2 X60
Inothi: Izidingo zichazwe kabanzi esigabeni se-Mechanical Properties sikaI-API 5L X52, okungabukwa ngokuchofoza ifonti eluhlaza okwesibhakabhaka uma unesithakazelo.
Ezinye Izivivinyo Zemishini
Uhlelo olulandelayo lokuhlolakusebenza ezinhlotsheni zamapayipi ensimbi e-SAW kuphela.
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.
Izinto zokuhlola kanye nemvamisa yokuhlola yezinye izinhlobo zamapayipi ingatholakala kuThebula 17 no-18 le-API 5L standard.
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 lensimbifuthi akufanele kube khona ukuvuza okuvela emzimbeni wokushisela noma wepayipi ngesikhathi sokuhlolwa.
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
Ukuze kube lula ukuwabuka nokusebenzisa, sihlele amafayela e-PDF eshejuli afanele. Ungalanda futhi ubuke la madokhumenti uma kudingeka.
Cacisa Ububanzi Bangaphandle Nobukhulu Bodonga
Amanani ajwayelekile obubanzi obucacisiwe bangaphandle kanye nobukhulu bodonga obucacisiwe bepayipi lensimbi anikezwe kuI-ISO 4200futhiI-ASME B36.10M.
Ukubekezelelana Okulinganayo
Izidingo ze-API 5L zokubekezelelana okunezilinganiso zichazwe kabanzi kuI-API 5L Ibanga BUkuze ugweme ukuphindaphinda, ungachofoza ifonti eluhlaza okwesibhakabhaka ukuze ubuke imininingwane efanele.
