    Amandla Nokuthembeka Kwamapayipi Esakhiwo Esigaba Esingenalutho: Ukubheka Okujulile Ku-Spiral Submerged Arc Welded Pipe kanye ne-API 5L Line Pipe

    Amandla Nokuthembeka Kwamapayipi Esakhiwo Esigaba Esingenalutho: Ukubheka Okujulile Ku-Spiral Submerged Arc Welded Pipe kanye ne-API 5L Line Pipe Isithombe Esifakiwe
    • Amandla Nokuthembeka Kwamapayipi Esakhiwo Esigaba Esingenalutho: Ukubheka Okujulile Ku-Spiral Submerged Arc Welded Pipe kanye ne-API 5L Line Pipe

    Incazelo emfushane:

    Lokhu kushiwo ukuhlinzeka ngezinga lokukhiqiza lesistimu yamapayipi ukuhambisa amanzi, igesi kanye nowoyela ezimbonini zikawoyela negesi yemvelo.

    Kunamazinga amabili wokucaciswa komkhiqizo, i-PSL 1 ne-PSL 2, i-PSL 2 inezidingo eziyisibopho zokulingana kwekhabhoni, ukuqina kwe-notch, amandla aphezulu wokukhiqiza namandla aqinile.

    IBanga B, X42, X46, X52, X56, X60, X65, X70 kanye ne-X80.

    I-Cangzhou Spiral Steel pipes group co., Ltd ihlinzeka ngamapayipi e-SAWH ahlanganisa ibanga ukusuka ku-API B kuya ku-X70, sathola isitifiketi se-API 5L eminyakeni edlule futhi manje amapayipi ethu olayini asetshenziswa kakhulu yi-CNPC, i-CPECC kumaphrojekthi awo wamapayipi.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Yethula:

    Emhlabeni wokuthuthukiswa kwengqalasizinda, ukukhetha izinto ezifanele kubalulekile.Amapayipi esakhiwo angenalutho idlala indima ebalulekile ekuhlinzekeni amandla, ukuqina nokwethembeka kumaphrojekthi ahlukahlukene.Kule bhulogi, sizohlola izici nezinzuzo zezinhlobo ezimbili ezibalulekile zamapayipi esakhiwo: ipayipi elishiselwe i-arc elingaphansi kwamanzi elisontekile kanye nepayipi lomugqa we-API 5L.

    Ipayipi elishiselwe i-arc elingaphansi kwe-Spiral:

    Ipayipi le-arc welded (SAW) elingaphansi kwamanzi, elaziwa nangokuthi ipayipi le-SSAW, lisetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza.Isici esiyingqayizivele seIpayipi le-SSAW ama-spiral seams ayo, anikeza amandla amakhulu namandla okuthwala umthwalo uma kuqhathaniswa nezinye izinhlobo zamapayipi.Lo mklamo oyingqayizivele usiza ukusabalalisa ingcindezi ngokulinganayo kulo lonke ipayipi, okwenza kube ekahle kumaphrojekthi adinga ubuqotho besakhiwo.

    Ukuhlolwa kwe-Hydrostatic

    incazelo yomkhiqizo1

    Ipayipi kufanele imelane nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi
    Amajoyinti akudingeki ahlolwe nge-hydrostatically, inqobo nje uma izingxenye zepayipi ezisetshenziswa umaka amajoyinti zihlolwe ngempumelelo nge-hydrostatically ngaphambi kokuhlanganisa.

    Ulayini Wendle

    Ukulandelela:
    Ngepayipi le-PSL 1, umkhiqizi uzosungula futhi alandele izinqubo ezibhaliwe zokugcinwa:
    Ubunikazi bokushisa kuze kube yilapho kwenziwa ukuhlolwa kwe-chmical ngakunye okuhlobene futhi kuboniswa ukuhambisana nezidingo ezishiwo
    Umazisi weyunithi yokuhlola kuze kube yilapho kwenziwa ukuhlolwa ngakunye kwemishini okuhlobene futhi kuboniswa ukuhambisana nezidingo ezishiwo
    Ngepayipi le-PSL 2, umenzi uzosungula futhi alandele izinqubo ezibhaliwe zokugcina ubunikazi bokushisa kanye nobunikazi beyunithi yokuhlola yalelo payipi.Lezo zinqubo zizohlinzeka ngezindlela zokulandela noma yibuphi ubude bepayipi endaweni yokuhlola efanele kanye nemiphumela yokuhlolwa kwamakhemikhali ehlobene.

    Enye yezinzuzo eziyinhloko zepayipi le-SSAW ukuguquguquka kwayo kokukhiqiza.Lawa mapayipi angakhiqizwa ngobukhulu obuhlukahlukene, ububanzi nobukhulu futhi angenziwa ngokwezifiso ukuze ahlangabezane nezidingo zephrojekthi ethile.Ngaphezu kwalokho, amapayipi ashiselwe i-arc angaphansi kwamanzi ayi-spiral ngokuvamile enziwa ngensimbi yezinga eliphezulu, okuwenza amelana nokugqwala futhi aqinisekise impilo ende yesevisi.

    API 5L Line Pipe:

    Ipayipi lomugqa we-API 5Liyipayipi lesakhiwo lesigaba esingenalutho elisetshenziswa kabanzi elihlangabezana nezindinganiso ze-American Petroleum Institute (API).La mapayipi aklanyelwe ukuthutha uketshezi, njengowoyela negesi yemvelo, ezindaweni ezikude.Ipayipi lomugqa we-API 5L yaziwa ngamandla ayo aphezulu, ukuqina nokumelana nezimo zemvelo ezimbi kakhulu.

    Inqubo yokukhiqiza yepayipi lomugqa we-API 5L ibandakanya izinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ukwethembeka kwayo.Lawa mapayipi enziwe nge-carbon steel futhi anezakhiwo ezinhle kakhulu zemishini.Ukunamathela ngokuqinile ezindinganisweni ze-API kuqinisekisa ukuthi lawa mapayipi angakwazi ukumelana nezingcindezi eziphezulu kanye noshintsho lokushisa, okuwenza afanelekele ukusetshenziswa okubalulekile embonini kawoyela negesi.

    Izinzuzo ezihlanganisiwe:

    Uma kuhlanganiswe ipayipi elishiselwe i-arc elingaphansi kwe-arc elisontekile kanye nepayipi lomugqa we-API 5L, ahlinzeka ngobuqotho besakhiwo nokwethembeka okungenakuqhathaniswa.Ama-spiral seams wepayipi le-SSAW kuhlanganiswe namandla nokuqina kwepayipi lomugqa we-API 5L kudala isistimu yokusekela eqinile yesakhiwo.

    Ngaphezu kwezinzuzo zazo ezihlukene, ukuhambisana kwepayipi elishiselwe i-arc elingaphansi kwamanzi elisontekile kanye nepayipi lomugqa we-API 5L kukhulisa ukusebenza kahle kwamaphrojekthi wamapayipi.Ukuguquguquka kwepayipi le-SSAW kuvumela ukuxhumana okulula nepayipi lomugqa we-API 5L, okuqinisekisa ukugeleza okungenamthungo koketshezi ngaphakathi kwenethiwekhi yamapayipi.

    Ekuphetheni:

    Amapayipi esakhiwo esinezigodi abaluleke kakhulu lapho kwakhiwa ingqalasizinda eqinile.Ukusetshenziswa okuhlangene kwepayipi le-SSAW kanye nepayipi lomugqa we-API 5L kunikeza isisombululo esinamandla esinikeza amandla, ukuqina nokuthembeka kwamaphrojekthi ahlukahlukene.Kungakhathaliseki ukuthi isekela izisekelo zezakhiwo ezinde noma ukuthutha uketshezi olubalulekile emabangeni amade, lawa mapayipi adlala indima ebalulekile ekuqinisekiseni ubude besikhathi eside nokuzinza kwengqalasizinda yethu.Ngokusebenzisa amandla epayipi elishiselwe i-arc elijikijelwe phansi kanye nokuthembeka kwepayipi lomugqa we-API 5L, onjiniyela bangakha isisekelo esiqinile sekusasa elingcono.
