    Ukuthuthukisa Ubuqotho Besakhiwo: Ipayipi Lensimbi Le-Spiral Welded Carbon Kunqubo Yensimbi Yepayipi yokushisela Isithombe Esifakiwe
    • Ukuthuthukisa Ubuqotho Besakhiwo: Ipayipi Lensimbi Le-Spiral Welded Carbon En Metal Pipe Welding Process

    Incazelo emfushane:

    Le ngxenye yaleli Zinga LaseYurophu icacisa izimo zobuchwepheshe zokulethwa kwesakhiwo esishiselwe ngendlela ebandayo, izingxenye ezingenalutho zamafomu ayindilinga, ayisikwele noma angunxande futhi isebenza ezingxenyeni ezingenalutho ezakhiwe ezibandayo ngaphandle kokwelashwa okushisayo okulandelayo.

    I-Cangzhou Spiral Steel Pipes Group Co., Ltd ihlinzeka ngengxenye engenalutho yamafomu ayindilinga amapayipi ensimbi okwakhiwa.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Ngenisa

    Ubuciko beukushisela ipayipi lensimbikudinga inhlanganisela evumelanayo yekhono, ukunemba kanye nezinto zekhwalithi ukuze kuqinisekiswe ubuqotho besakhiwo sezinhlelo zokusebenza ezihlukahlukene.Phakathi kwezinhlobo eziningi zamapayipi, i-spiral welded carbon steel pipe, njengepayipi le-X42 SSAW, idume ngamandla ayo aphakeme, ukuqina kanye nokusebenza kahle kwezindleko.Kule bhulogi, sizohlola ukubaluleka kwamapayipi ensimbi ensimbi ashiselwe ngokuvunguza enqubweni yokushisela amapayipi ensimbi, sihlola inqubo yawo yokukhiqiza, izinzuzo nezindawo zokufaka isicelo.

    a.Indlela ye-deoxidation ikhethwe kanje:
    FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).
    b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

    Inqubo yokukhiqiza

    Ipayipi elishiselwe ku-Spiral, elaziwa nangokuthi i-SSAW (spiral submerged arc welded) pipe, lakhiwe kusetshenziswa amasu okushisela okugobile kanye nama-arc angaphansi kwamanzi.Inqubo iqala ngokwelashwa konqenqema lomucu wensimbi ogoqiwe bese igobisa umucu ube yisimo esithandelayo.Ukushisela kwe-arc okuzenzakalelayo okungaphansi kwamanzi bese kusetshenziselwa ukuhlanganisa imiphetho yamapheshana, kwakheka ukushisela okuqhubekayo ngobude bepayipi.Le ndlela iqinisekisa ukuthi ilunga liqinile futhi liqinile ngenkathi kunciphisa amaphutha futhi igcina ubuqotho besakhiwo.

    Izinzuzo Kuvunguza ashiselwe carbon steel pipe

    1. Amandla nokuqina:Kuvunguza ashiselwe carbon steel pipeyaziwa ngamandla ayo aphakeme nokuqina, okwenza ifaneleke izinhlelo zokusebenza ezidinga ukumelana nokucindezela okukhulu nokusebenza kwesikhathi eside.

    2. Ukusebenza Kwezindleko: Lawa mapayipi anikeza isixazululo esingabizi kakhulu ngenxa yenqubo yawo yokukhiqiza ephumelelayo, izindleko eziphansi zezinto ezingavuthiwe, kanye nezidingo ezincishisiwe zabasebenzi uma kuqhathaniswa nezinye izinhlobo zamapayipi.

    3. Ukuhlukahluka: Ukuguquguquka kwepayipi lensimbi yensimbi ye-spiral welded carbon livumela ukuthi lisetshenziswe ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa ukuthuthwa kwamanzi, ukuthutha uwoyela negesi, izakhiwo zokunqwabelanisa, izinhlelo zokukhucululwa kwendle, nezinqubo ezihlukahlukene zezimboni.

    4. Ukunemba kwe-Dimensional: Inqubo yokwenza i-spiral ingakwazi ukulawula ngokunembile ubukhulu nodonga lwepayipi, iqinisekise ukunemba nokufana kokukhiqiza.

    Izindawo zokufaka izicelo

    1. Imboni kawoyela negesi yemvelo: Amapayipi ensimbi e-Spiral welded carbon steel asetshenziswa kakhulu embonini kawoyela negesi yemvelo, ikakhulukazi ekuthuthweni kukawoyela ongahluziwe, igesi yemvelo kanye nemikhiqizo kaphethiloli.Amandla abo kanye nekhono lokumelana nezindawo ezinengcindezi ephezulu kubenza balungele amapayipi ahamba ibanga elide.

    2. Ukudluliswa kwamanzi: Noma ngabe okokuphakelwa kwamanzi kamasipala noma ngezinjongo zokunisela, amapayipi ensimbi ensimbi e-spiral welded ahlinzeka ngesixazululo esihle kakhulu ngenxa yokumelana nokugqwala kwawo, amandla kanye nokuwafaka kalula.

    3. Ukwesekwa kwesakhiwo: Lolu hlobo lwamapayipi lusetshenziswa kakhulu embonini yezokwakha ukuze kuhlinzekwe ukwesekwa kwesakhiwo sezakhiwo, amabhuloho, amadokhu kanye neminye imiklamo yengqalasizinda.Ukuqina kwabo nokumelana nezakhi zangaphandle kubenza bathembeke ezinhlelweni ezinjalo.

    4. Izicelo Zezimboni: Amapayipi e-Spiral welded carbon steel asetshenziswa emikhakheni ehlukahlukene yezimboni njengokucubungula amakhemikhali, izimboni zamandla kanye nokusebenza kwezimayini ngenxa yekhono lawo lokusingatha amazinga okushisa aphezulu, izingcindezi kanye nezindawo ezigqwalile.

    Ekuphetheni

    Kuvunguza ashiselwe carbon steel pipe, ezifanaX42 SSAW ipayipi, iguqule inqubo yokushisela ipayipi lensimbi, ilethe izinzuzo eziningi ezimbonini ezahlukene.Amandla azo, ukuqina, ukuphumelela kwezindleko kanye nokunemba kobukhulu bawo kuqinisekisa ubuqotho besakhiwo emisebenzini ehlukahlukene.Ikhono lokumelana nezingcindezi ezinkulu, amazinga okushisa kanye nezindawo ezigqwalile kuyenza ilungele ukudluliswa kukawoyela negesi, ukuhlinzekwa kwamanzi kanye neminye imikhakha yezimboni.Ngakho-ke, uma kuziwa ekushiseni kwamapayipi ensimbi, ukusetshenziswa kwamapayipi ensimbi ensimbi e-spiral ashiselwe kuhlala kuyisixazululo esinokwethenjelwa nesisebenzayo sokuqinisekisa ingqalasizinda ehlala isikhathi eside futhi eqinile.

    Ukuhlolwa kwe-Hydrostatic

    Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi kumfutho we-hydrostatic ozokhiqiza odongeni lwamapayipi ingcindezi engekho ngaphansi kuka-60% wamandla esivuno amancane ashiwo ekamelweni lokushisa.Ingcindezi izonqunywa yi-equation elandelayo:
    P=2St/D

    Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

    Ubude bepayipi ngalinye buzokalwa ngokwehlukana futhi isisindo salo angeke sihluke ngaphezu kuka-10% ngaphezulu noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
    Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle
    Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ​​ngaphansi kogqinsi olushiwo
