    • I-X42 SSAW PILEPI SPHORE SHORED TUBED

    Incazelo emfushane:

    Lokhu kucaciswa ukuhlinzeka ngezinga lezokukhiqiza ngohlelo lwepayipi ukuhambisa amanzi, igesi kanye namafutha asezimbonini zegesi zemvelo.

    Kunamazinga amabili okucaciswa komkhiqizo, i-PSL 1 nePSL 2, i-PSL 2, inezidingo eziphoqelekile zekhabhoni elingana, ukuqina kwe-notch, amandla aphezulu wesivuno namandla aphezulu.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Yethula:

    Ensimini yamapayipi ensimbi, kusetshenziselwa amasu ahlukahlukene we-welding ukufeza ukuxhumana okuphezulu nokunokwethenjelwa. Enye indlela enjaloKuvunguza i-arc egxilile ye-arc(Saw), edlala indima ebalulekile ekukhiqizweni kwepayipi le-x42 ssaw. Njengomholi wezimboni, iCangegzhou Spiral Steel Pipe Group Co, Ltd. Izinzuzo zokusebenzisa i-arlding ye-arlding ephakathi nendawo ephansi ekhiqizweni kwepayipi elinenkani elinomoya.

    Funda nge-arlding ye-arldi ephakathi nendawo ephakathi nendawo (saw):

    Kuvunguza i-arc ye-welding ephakathi, eyaziwa nangokuthi i-SAY, iyindlela ekhethekile ye-welding esetshenziselwa ukukhiqiza amapayipi anezinwele ezinomoya anjengeX42 ssaw ipayipi. Le ndlela ifaka ukuncibilikisa i-wire flux kanye nensimbi eyisisekelo usebenzisa ukushisa okukhiqizwe yi-arc yokuhlanganiswa phakathi kocingo kanye noFlux ngaphansi kwesendlalelo se-flux. Isendlalelo se-Flux sisebenza njengesithiyo esivikelayo, ukuvimbela ukungcola komoya ekuphazamiseni inqubo yokudambisa. Le ndlela inezinzuzo eziningana ngaphezu kwamanye amasu we-welding.

    Incazelo Yomkhiqizo1

    Izinzuzo ze-arlding ezingenisiwe ze-arldi evulekile:

    1. Ama-Welds aphezulu futhi aphezulu wekhwalithi ephezulu Lapho i-arc ifakwe ku-flux, yakha indawo elawulwayo evikela indawo elungiselelwe ezintweni zangaphandle, iqinisekisa ukuhlangana okungaguquki nokuthembekile. Lokhu kuphumela ekukhiqizweni kwamapayipi anama-welded ane-welded anamandla ahlukile nokuqina.

    Ukubalwa kobude be-welding ubude

    2. Ukusebenza kahle okwengeziwe: I-Welding ye-ARCH ephakathi nendawo ephakathi inikeza ukusebenza kahle ngenxa yemvelo yayo ezenzakalelayo. Le nqubo ifaka phakathi okuqhubekayo, ukondla okuzenzakalelayo kocingo lwe-welding, okuholela ekukhiqizweni okusheshayo ngenkathi kugcinwa ukunemba. Amanani aphezulu okuthembela okuphezulu kanye nokuthembela okuncane kwabasebenzi bezandla abamba iqhaza ekusebenzeni nasekusebenzeni kwezindleko.

    I-3. Ilungele izinhlelo zokusebenza ezahlukahlukene: I-X42 SSAW PIPED eyenziwe nge-Welding ye-Welding ephakathi nendawo efakwe emanzini asetshenziswa kakhulu ezimbonini eziningi. Lawa mapayipi asetshenziswa e-oyili kanye negesi zokuhamba, amapayipi amanzi, ukwakheka kwesakhiwo, izisekelo zokuphamba, nokuningi. Ukuguquguquka okuhlukahlukene kanye nokwethenjwa kweshubhu le-x42 ssaw kwenza kube kuhle ngezicelo ezibucayi.

    I-4. Izakhiwo ezithuthukisiwe zemishini: Indlela ye-SAWE iqinisekisa ukulawula okungcono kwamapharamitha we-welding ngesikhathi sokuqanjwa kwamapayipi we-x42 angenamikhawulo e-arc. Lokhu kulawulwa kungathuthukisa izakhiwo zemishini, kufaka phakathi ubulukhuni bethonya, amandla okuthela kanye namandla ashubile. Ngenxa yalokhu, la mapayipi anokumelana kahle namabutho angaphandle futhi alungele ngisho nezindawo ezinokhahlo.

    Ekuphetheni:

    Lapho sihlola umhlaba we-arlding we-arlding we-arldi ephakathi nendawo e-X42 SSAW Pipe Production, kuyacaca ukuthi kungani le ndlela isetshenziswa kabanzi embonini yensimbi. I-Welding ye-Weldged ephakathi nendawo enikezela ngezinzuzo eziningi ezinjenge-seld ye-weld engaguquki, ukuguquguquka okuthuthukile kanye namapayipi wensimbi athuthukisiwe, anjenge-x42 ssaw amapayipi, ahlangabezana namazinga aphezulu kakhulu. Ngakho-ke, ngokuya ngokwethembeka, ukuqina kanye nokusebenza, i-X42 SSAW TULUS ITSAS I-PERSTION FETE FOREST YOKUQALA KWAMAHHALA WEZINTOLO ZAMAHHALA.
