    Ukushisela Umugqa Wepayipi Umthungo Ojikelezayo Amapayipi Ensimbi

    Ukushisela Umugqa Wepayipi Umthungo Ojikelezayo Amapayipi Ensimbi Isithombe Esifakiwe
    • Ukushisela Umugqa Wepayipi Umthungo Ojikelezayo Amapayipi Ensimbi

    Incazelo emfushane:

    Siyakwamukela esingenisweni somkhiqizo wepayipi lomthungo ojikelezayo olethwe kini yiCangzhou Spiral Steel Pipe Group Co., Ltd., umenzi ohamba phambili waseShayina wamapayipi ensimbi ajikelezayo kanye nemikhiqizo yokumboza amapayipi.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., yethuamapayipi omthungo ojikelezayoyimikhiqizo esezingeni eliphezulu ehlangabezana nezindinganiso eziphakeme kakhulu embonini. Amapayipi ethu aklanyelwe izinhlelo zokusebenza ezahlukahlukene futhi aziwa ngokuqina kwawo, amandla kanye nokumelana nokugqwala.

    I-Carbon iyinto eyisisekelo kakhulu ensimbini futhi iyisisekelo sokuhlukanisa insimbi nensimbi. Amapayipi ethu omthungo ojikelezayo enziwe ngensimbi yekhabhoni esezingeni eliphezulu eqinisekisa amandla aphezulu nokuqina. Ngokuqukethwe kwawo kwekhabhoni okuphezulu, amapayipi ethu afanelekela ukusetshenziswa okubanzi kwezimboni.

    Ngaphezu kwekhabhoni, amashubhu ethu omthungo ojikelezayo aqukethe ezinye izinto ezibalulekile njenge-nickel ne-chromium. I-Nickel iyinsimbi ye-ferromagnetic enezela emandleni kanye nokupholisha kwepayipi. Ngaphezu kwalokho, imelana nokugqwala futhi iqinisekisa impilo yenkonzo ende yamapayipi ethu. I-Chromium, ngakolunye uhlangothi, iyinto ebalulekile ensimbini engagqwali futhi inokumelana okuhle kakhulu nokugqwala. Ukufakwa kwe-chromium kumapayipi ethu omthungo ojikelezayo kwandisa isikhathi eside nokuthembeka kwawo.

    Enye yezinzuzo eziyinhloko zamapayipi ethu omthungo ojikelezayo ukwakheka kwawo okungenamthungo, okufezwa ngobuchwepheshe bokushisela obuthuthukisiwe. Ubuchwepheshe bethu bokushisela be-SAWH (Submerged Arc Spiral Welding) obusezingeni eliphezulu buqinisekisa isibopho esiqinile nesihlala isikhathi eside phakathi kwamapuleti ensimbi epayipi. Lobu buchwepheshe bokushisela abugcini nje ngokuthuthukisa izakhiwo zemishini zepayipi, kodwa futhi buqinisekisa ubuso bangaphakathi obubushelelezi, obuhambisana nokugeleza okuphumelelayo koketshezi noma amagesi ahlukahlukene.

    Amapayipi ethu omthungo ojikelezayo asetshenziswa kabanzi ezimbonini eziningi, okuhlanganisa uwoyela negesi, ezokuthutha ngamanzi, ezokwakha kanye nokuthuthukiswa kwengqalasizinda. Angasetshenziswa kumaphrojekthi asogwini kanye nasogwini kanye nasezinhlelweni zamapayipi ngezinhloso ezahlukene. Ngokumelana kwawo okuhle kakhulu nokugqwala kanye namandla aphezulu okudonseka, amapayipi ethu ayisinqumo sokuqala sokushisela amapayipi ezindaweni ezinzima.

    a. Indlela yokususa i-oxidation ichazwa kanje:

    FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo).

    b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

    Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., sibeka ikhwalithi kanye nokwaneliseka kwamakhasimende kuqala. Ithimba lethu lochwepheshe abazinikele liqinisekisa ukuthi ipayipi ngalinye lomthungo ojikelezayo lidlula ezinqubweni zokulawula ikhwalithi eziqinile ukuze kuhlangatshezwane nezindinganiso zomhlaba wonke. Ngaphezu kwalokho, sinikeza uhla oluphelele lwezinketho zokumboza amapayipi, kufaka phakathi i-epoxy, i-polyethylene kanye nodaka lwesimende, ukuze sithuthukise ukumelana nokugqwala kwepayipi futhi sandise impilo yalo yesevisi.

    Ipayipi le-SSAW

    Ngokufigqiwe

    I-Cangzhou Spiral Steel Pipe Group Co., Ltd. iyaziqhenya ngokuhlinzeka ngamapayipi omthungo ojikelezayo asezingeni eliphezulu ezinhlobonhlobo zezicelo. Sigxila ekukhiqizeni ngokunemba, ubuchwepheshe bokushisela obuthuthukisiwe kanye nezinto ezisezingeni eliphezulu ukuze sinikeze amakhasimende izixazululo ezithembekile nezisebenzayo zezidingo zawo zokufaka amapayipi. Sithembe ukuthi sizohlangabezana nazo zonke izidingo zakho futhi sizizwele mathupha ukuthembeka nokuqina kwamapayipi ethu omthungo ojikelezayo.
