Ipayipi le-X42 SSAW Spiral Welded Tube

Incazelo emfushane:

Le ncazelo iwukunikeza indinganiso yokukhiqiza yesistimu yamapayipi yokuhambisa amanzi, igesi kanye namafutha ezimbonini zikawoyela negesi yemvelo.

Kunezigaba ezimbili zokucaciswa komkhiqizo, i-PSL 1 kanye ne-PSL 2, i-PSL 2 inezidingo ezidingekayo zokulingana kwekhabhoni, ukuqina kwe-notch, amandla aphezulu okukhiqiza kanye namandla okudonsa.

Yethula:

Emkhakheni wamapayipi ensimbi, kusetshenziswa amasu ahlukahlukene okushisela ukuze kufezwe ukuxhumana okuseqophelweni eliphezulu nokuthembekile. Enye indlela enjalo iwukubaukushisela i-arc engaphansi komhlaba okujikelezayo(SAW), edlala indima ebalulekile ekukhiqizweni kwepayipi le-X42 SSAW. Njengomholi embonini, i-Cangzhou Spiral Steel Pipe Group Co., Ltd., eyaziwa ngomkhiqizo wayo we-Wuzhou, inamathela ezindinganisweni zomhlaba wonke futhi iqinisekisa ukuthi imikhiqizo yayo (kufaka phakathi ipayipi elihlanganisiwe le-X42 spiral arc) ihlangabezana ne-API Spec 5L, ASTM A139, ASTM A252 kanye ne-EN 10219. Kule bhulogi sihlola umhlaba othakazelisayo wepayipi le-X42 SSAW, siqokomisa izinzuzo zokusebenzisa ukushisela kwe-arc okuhlanganisiwe kwe-spiral ekukhiqizweni kwepayipi elihlanganisiwe le-spirally.

Funda nge-Spiral Submerged Arc Welding (SAW):

Ukushisela i-arc engaphansi komhlaba okujikelezayo, okwaziwa nangokuthi i-SAW, kuyindlela ekhethekile yokushisela esetshenziselwa ukukhiqiza amapayipi ashiselwe ngokujikelezayo njengeIpayipi le-X42 SSAWLe ndlela ihilela ukuncibilikisa i-wire flux kanye ne-base metal kusetshenziswa ukushisa okukhiqizwa ukushisa kwe-arc phakathi kwe-wire kanye ne-flux ngaphansi kwe-flux layer. I-flux layer isebenza njengesivikelo esivikelayo, ivimbela ukungcola komoya ukuthi kungaphazamisi inqubo yokunamathisela. Le ndlela inezinzuzo eziningana ngaphezu kwezinye izindlela zokushisela.

Ukuhlolwa Kwamanzi

incazelo yomkhiqizo1

Izinzuzo zokushisela i-arc engaphansi komhlaba nge-spiral:

1. Ukushisela okuqinile nokusezingeni eliphezulu: Indlela ye-SAW esetshenziswa epayipini le-X42 SSAW ikhiqiza ukushisela okufanayo nokusezingeni eliphezulu. Lapho i-arc ifakwa emanzini, idala indawo elawulwayo evikela indawo yokushisela ezintweni zangaphandle, iqinisekisa ukuhlangana okuqinile nokuthembekile. Lokhu kuphumela ekukhiqizweni kwamapayipi ashisiwe ajikelezayo anamandla amakhulu nokuqina.

Ukubalwa Kobude Bokushisela Ipayipi Ejikelezayo

2. Ukusebenza kahle okwandisiwe: Ukushisela i-arc engaphansi komhlaba okujikelezayo kunikeza ukusebenza kahle okukhulu ngenxa yemvelo yayo ezenzakalelayo. Le nqubo ihilela ukuphakelwa okuqhubekayo, okuzenzakalelayo kwentambo yokushisela, okuholela ekukhiqizeni okusheshayo ngenkathi kugcinwa ukunemba. Amazinga aphezulu okufakwa kanye nokuthembela okuncane emsebenzini wezandla kunegalelo ekusebenzeni kahle kanye nokusebenza kahle kwezindleko.

3. Ifanele ukusetshenziswa okuhlukahlukene: Ipayipi le-X42 SSAW elenziwe ngokushisela i-arc engaphansi komhlaba e-spiral lisetshenziswa kabanzi ezimbonini eziningi. Lawa mapayipi asetshenziswa ekuthuthweni kukawoyela negesi, emapayipini amanzi, ekusekelweni kwesakhiwo, ekufakeni izisekelo, nokuningi. Ukuguquguquka nokuthembeka kwepayipi le-X42 SSAW kwenza libe yindawo ekahle yokusetshenziswa okubalulekile.

4. Izakhiwo ezithuthukisiwe zemishini: Indlela ye-SAW iqinisekisa ukulawulwa okungcono kwamapharamitha okushisela ngesikhathi sokwenziwa kwamapayipi e-X42 afakwe i-arc ac welded. Lokhu kulawula kungathuthukisa izakhiwo zemishini, okuhlanganisa ukuqina komthelela, amandla okukhiqiza kanye namandla okuthambekela. Ngenxa yalokho, la mapayipi anokumelana okuhle kakhulu namandla angaphandle futhi afaneleka ngisho nasezindaweni ezinzima.

Ekuphetheni:

Uma sihlola umhlaba wokushisela i-arc engaphansi komhlaba ekukhiqizweni kwamapayipi e-X42 SSAW, kuyacaca ukuthi kungani le ndlela isetshenziswa kabanzi embonini yensimbi. Ukushisela i-arc engaphansi komhlaba okuphakathi kwe-Spiral kunikeza izinzuzo eziningi ezifana nokuthungwa okuhlala njalo, ukusebenza kahle okwandisiwe, ukuguquguquka kanye nezakhiwo ezithuthukisiwe zemishini, okuqinisekisa ukuthi amapayipi ahlanganisiwe ngokugobhoza, njengepayipi lensimbi le-X42 SSAW elikhiqizwe yi-Cangzhou Spiral Steel Pipe Group Co., Ltd., ahlangabezana nezindinganiso zekhwalithi ephezulu. Ngakho-ke, maqondana nokuthembeka, ukuqina kanye nokusebenza, ipayipi le-X42 SSAW libonakala liyisinqumo esihle kakhulu sezinhlelo zokusebenza ezahlukahlukene zezimboni.

Okwedlule: Amapayipi Esakhiwo Angenasikwele Ipayipi Elihlanganisiwe Elingenamthungo

Olandelayo: Amandla Nokuthembeka Kwamapayipi Esakhiwo Anezingxenye Ezingenalutho: Ukubuka Okujulile Ipayipi Elihlanganisiwe Le-Arc Elihlanganisiwe Eligobhozayo kanye Nepayipi Lomugqa le-API 5L
