    Incazelo emfushane:

    Le ncazelo ihlanganisa izinqwaba zamapayipi ensimbi odongeni ezijwayelekile ezimise okwesilinda futhi isebenza ezinqwabeni zamapayipi lapho isilinda sensimbi sisebenza khona njengelungu elihlala njalo elithwala umthwalo, noma njengegobolondo lokwenza izinqwaba zekhonkrithi ezifakwe endaweni.

    Iqembu lamapayipi ensimbi e-Cangzhou Spiral Steel co.,ltd lihlinzeka ngamapayipi ahlanganisiwe okusetshenziswa komsebenzi wokufaka inqwaba ngobubanzi obusukela ku-219mm kuya ku-3500mm, kanye nobude obubodwa obufika kumamitha angu-35.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Impahla Yomshini

    Ibanga 1 Ibanga lesi-2 Ibanga lesi-3
    Iphuzu Lokukhiqiza noma amandla okukhiqiza, min, i-Mpa(PSI) 205(30 000) 240(35 000) 310(45 000)
    Amandla okudonsa, i-min, i-Mpa(PSI) 345(50 000) 415(60 000) 455(66 0000)

    Ukuhlaziywa komkhiqizo

    Insimbi akumele ibe ne-phosphorus engaphezu kuka-0.050%.

    Izinguquko Ezivumelekile Ezisindweni Nasezilinganisweni

    Ubude ngabunye benqwaba yamapayipi kufanele bulinganiswe ngokwehlukana futhi isisindo sawo akufanele sihluke ngaphezu kuka-15% noma u-5% ngaphansi kwesisindo sawo esicatshangelwayo, kubalwe kusetshenziswa ubude bawo kanye nesisindo sawo 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

    Ubude

    Ubude obungahleliwe obubodwa: 16 kuya ku-25ft (4.88 kuya ku-7.62m)
    Ubude obuphindwe kabili obungahleliwe: ngaphezu kwamafidi angu-25 kuya ku-35 (7.62 kuya ku-10.67m)
    Ubude obufanayo: ukuhlukahluka okuvunyelwe ±1in

    Ukuphela

    Izinqwaba zamapayipi kumele zifakwe iziphetho ezingenalutho, bese kuthi izimbobo ezisemaphethelweni zisuswe.
    Uma ukuphela kwepayipi okuchazwe ukuthi kube yiziphetho ze-bevel, i-engeli kufanele ibe ngama-degree angu-30 kuya kwangu-35.

    Ukumaka umkhiqizo

    Ubude ngabunye benqwaba yamapayipi kufanele buphawulwe ngokugqama ngokufaka isitembu, ukugxisha, noma ukugoqa ukuze kuboniswe: igama noma uhlobo lomkhiqizi, inombolo yokushisa, inqubo yomkhiqizi, uhlobo lomthungo ogobile, ububanzi bangaphandle, ukujiya kodonga okujwayelekile, ubude, nesisindo ngobude beyunithi, ukubizwa kwencazelo kanye nebanga.
