    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.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Yethula:

    Emkhakheni wamapayipi ensimbi, amasu ahlukahlukene we-welding asetshenziswa ukuze kuzuzwe ukuxhumana okusezingeni eliphezulu nokuthembekile.Enye indlela enjaloi-spiral submerged arc welding(SAW), edlala indima ebalulekile ekukhiqizweni kwepayipi le-X42 SSAW.Njengomholi wemboni, iCangzhou Spiral Steel Pipe Group Co., Ltd., eyaziwa ngohlobo lwayo lweWuzhou, ithobela izindinganiso zamazwe ngamazwe futhi iqinisekisa ukuthi imikhiqizo yayo (okuhlanganisa i-X42 spiral submerged arc welded pipe) ihlangabezana ne-API Spec 5L, ASTM A139, ASTM A252 kanye ne-EN 10219. Kule bhulogi singena ezweni elithakazelisayo lepayipi le-X42 SSAW, sigqamisa izinzuzo zokusebenzisa i-arc welding efakwe emanzini e-spiral ekukhiqizeni ipayipi elishiselwe ngokuzumayo.

    Funda mayelana ne-Spiral Submerged Arc Welding (SAW):

    I-Spiral submerged arc welding, eyaziwa nangokuthi i-SAW, iyindlela ekhethekile yokushisela esetshenziselwa ukwakha amapayipi ashiselwe ngokuvunguza njengeX42 SSAW ipayipi.Indlela yokusebenza ihlanganisa ukuncibilikisa i-wire flux nesisekelo sensimbi kusetshenziswa ukushisa okukhiqizwa ukusha kwe-arc phakathi kwentambo nokugeleza ngaphansi kwesendlalelo se-flux.Isendlalelo se-flux sisebenza njengesivikelo sokuzivikela, esivimbela ukungcola komkhathi ekuphazamiseni inqubo yokuhlanganisa.Le ndlela inezinzuzo eziningana ngaphezu kwamanye amasu welding.

    incazelo yomkhiqizo1

    Izinzuzo ze-spiral submerged arc welding:

    1. Ukushisela okungaguquki nokuphezulu: Indlela ye-SAW esetshenziswa epayipini le-X42 SSAW ikhiqiza ama-weld afanayo kanye nekhwalithi ephezulu.Uma i-arc ifakwe emanzini, idala indawo elawulwayo evikela indawo ye-solder kusuka ezintweni zangaphandle, iqinisekisa amalunga angaguquki futhi anokwethenjelwa.Lokhu kuphumela ekukhiqizweni kwamapayipi ashiselwe athandelene anamandla angavamile nokuqina.

    Spiral Pipe Welding Ubude Ukubala

    2. Ukusebenza kahle okwandisiwe: I-Spiral submerged arc welding inikeza ukusebenza kahle okuphawulekayo ngenxa yemvelo yayo ezenzakalelayo.Inqubo ihilela ukuphakela okuqhubekayo, okuzenzakalelayo kocingo lokushisela, okuholela ekukhiqizeni okusheshayo kuyilapho kugcinwa ukunemba.Amazinga aphezulu okufakwa kwemali kanye nokuncika okuncane emsebenzini wezandla kunomthelela ekusebenzeni kahle nasekungabini kwezindleko.

    3. Ifanele ukusetshenziswa okuhlukahlukene: Ipayipi le-X42 SSAW elakhiwe nge-spiral submerged arc welding lisetshenziswa kabanzi ezimbonini eziningi.Lawa mapayipi asetshenziswa ekuthuthweni kukawoyela negesi, amapayipi amanzi, ukusekelwa kwesakhiwo, izisekelo zokunqwabelanisa, nokunye.Ukuguquguquka nokuthembeka kweshubhu ye-X42 SSAW kuyenza ilungele izinhlelo zokusebenza ezibucayi.

    4. Izakhiwo zemishini ezithuthukisiwe: Indlela ye-SAW iqinisekisa ukulawula okungcono kwemingcele yokushisela ngesikhathi sokwenziwa kwamapayipi ashiselwe angaphansi kwe-arc angu-X42 asontekile.Lokhu kulawula kungathuthukisa izici zemishini, okuhlanganisa ukuqina komthelela, amandla esivuno namandla aqinile.Ngenxa yalokho, lawa mapayipi anokumelana okuhle kakhulu namandla angaphandle futhi afaneleka ngisho nasezindaweni ezinzima.

    Ekuphetheni:

    Uma sihlola umhlaba we-spiral submerged arc welding ekukhiqizeni amapayipi e-X42 SSAW, kuyacaca ukuthi kungani le ndlela isetshenziswa kakhulu embonini yensimbi.I-Spiral submerged arc welding ihlinzeka ngezinzuzo eziningi njengokushisela okungaguquguquki, ukusebenza kahle okwandisiwe, ukuguquguquka kwezinto kanye nezakhiwo ezithuthukisiwe zemishini, ukuqinisekisa ukuthi amapayipi ashiselwe ngokuvunguza, njengamapayipi ensimbi angu-X42 SSAW akhiqizwe yi-Cangzhou Spiral Steel Pipe Group Co., Ltd., ahlangabezana namazinga aphezulu kakhulu izindinganiso zekhwalithi.Ngakho-ke, mayelana nokuthembeka, ukuqina nokusebenza, ithubhu ye-X42 SSAW ifakazela ukuthi iyisinqumo esihle kakhulu ezinhlobonhlobo zezicelo zezimboni.
