    I-S355 J0 Spiral Steel Tube yakhiwe ngokunemba kanye nobuhle obuqinisekisa ukuqina kanye nokuthembeka ekusebenzeni kwayo. Iyipuleti lensimbi eliyisakhiwo esinamandla aphezulu, elisetshenziswa kabanzi ekukhiqizeni imishini, imishini yezimboni ezisindayo, imishini yokwakha, imishini yezimayini, imishini yezimayini zamalahle, izakhiwo zamabhuloho, ama-crane, amajeneretha, imishini yamandla omoya, amabheringi kanye neminye imboni. Amagobolondo, izingxenye zokucindezela, ama-turbine omusi, izingxenye ezifakiwe, izingxenye zemishini.

    Esinye sezici eziyinhloko ze-S355 J0 Spiral Steel Tube ukuthi isebenziseka ngezindlela eziningi. Amapayipi ensimbi ajikelezayo asetshenziswa kabanzi futhi angahlangabezana nezidingo ezahlukene zezimboni ezahlukene. Kungakhathaliseki ukuthi imishini esindayo noma amaphrojekthi engqalasizinda, leli payipi linikeza ukusebenza okumangalisayo namandla, okwenza lifaneleke kakhulu ekusetshenzisweni okudinga amandla.

    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., siyaziqhenya ngamakhono ethu okukhiqiza asezingeni eliphezulu. Njengoba sinemigqa yokukhiqiza engu-13 yamapayipi ensimbi ajikelezayo, kanye nemigqa yokukhiqiza engu-4 yezindlela zokulwa nokugqwala kanye nokushisa, sesibe ngumhlinzeki ohamba phambili embonini. Ubuchwepheshe bethu bokukhiqiza obuthuthukisiwe busenza sikwazi ukukhiqiza amapayipi ensimbi ajikelezayo anobubanzi obungu-Φ219-Φ3500mm kanye nobukhulu bodonga obungu-6-25.4mm.

    Ukushisela i-Arc Ecmerged Helical

    Sizibophezele ekuhlinzekeni ngemikhiqizo esezingeni eliphezulu ehlangabezana nezindinganiso eziphakeme kakhulu embonini. Ithimba lethu lochwepheshe abanamakhono liqinisekisa ukuthi ipayipi ngalinye lihlolwa ngokuqinile ukuze lithole amandla, ukuqina kanye nokusebenza kahle. Ngaphezu kwalokho, sibeka phambili ukwaneliseka kwamakhasimende futhi sihlinzeka ngensizakalo enhle kakhulu ngemuva kokuthengisa kumakhasimende ethu abalulekile.

    Ngepayipi lethu lensimbi elijikelezayo le-S355 J0, ungathembela kwikhwalithi ephezulu kanye nokuthembeka okumelelwa yibhrendi yethu. Kungakhathaliseki ukuthi usembonini yemishini esindayo noma yokwakha, amapayipi ethu ensimbi ajikelezayo azodlula okulindelwe futhi alethe imiphumela emihle kakhulu.

    Khetha i-Cangzhou Spiral Steel Pipe Group Co., Ltd. kuzo zonke izidingo zakho zamapayipi ensimbi ajikelezayo. Hlanganyela nathi namuhla futhi uzizwele ikhwalithi nokuthembeka okungenakuqhathaniswa kwemikhiqizo yethu.

    Ukuhlolwa Kwamanzi

    Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwepayipi ukucindezeleka okungaphansi kuka-60% wamandla amancane okukhiqiza ashiwo ekushiseni kwegumbi. Ukucindezela kuzonqunywa yi-equation elandelayo:
    P=2St/D

    Izinguquko Ezivumelekile Ezisindweni Nasezilinganisweni

    Ubude bepayipi ngalinye kufanele bulinganiswe ngokwehlukana futhi isisindo salo akumele sihluke ngaphezu kuka-10% noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo kanye nesisindo salo ngobude beyunithi ngayinye.
    Ububanzi bangaphandle akufanele buhluke ngaphezu kuka-±1% kusuka kububanzi obujwayelekile bangaphandle obubekiwe
    Ubukhulu bodonga nganoma yisiphi isikhathi akufanele bube ngaphezu kuka-12.5% ​​ngaphansi kobukhulu bodonga obubekiwe
