    Amapayipi Omugqa we-Api 5l Ibanga B Kuya ku-X70 Od Kusukela ku-219mm Kuya ku-3500mm

    Amapayipi Omugqa we-Api 5l Ibanga B Kuya ku-X70 Od Kusukela ku-219mm Kuya ku-3500mm Isithombe Esivelele
    • Amapayipi Omugqa we-Api 5l Ibanga B Kuya ku-X70 Od Kusukela ku-219mm Kuya ku-3500mm

    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.

    Ibanga B, X42, X46, X52, X56, X60, X65, X70 kanye ne-X80.

    Iqembu lamapayipi ensimbi e-Cangzhou Spiral Steel co.,ltd lihlinzeka ngamapayipi e-SAWH ahlanganisa ibanga elisukela ku-API B kuya ku-X70, sathola isitifiketi se-API 5L eminyakeni edlule futhi manje amapayipi ethu omugqa asetshenziswa kakhulu yi-CNPC, i-CPECC kumaphrojekthi abo amapayipi.

    Ukuhlolwa Kwamanzi

    incazelo yomkhiqizo1

    Ipayipi kufanele imelane nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo wokushisela noma umzimba wepayipi.
    Ama-jointer akudingeki ahlolwe ngamanzi, uma nje izingxenye zamapayipi asetshenziswe ekumaka ama-jointer zihlolwe ngempumelelo ngamanzi ngaphambi kokusebenza kokujoyina.

    Ukulandelela:
    Kumapayipi e-PSL 1, umenzi kufanele asungule futhi alandele izinqubo ezibhaliwe zokulungisa:
    Ubunikazi bokushisa kuze kube yilapho kwenziwa ukuhlolwa ngakunye kwe-chmical okuhlobene futhi kuboniswa ukuhambisana nezidingo ezichaziwe
    Ubunikazi beyunithi yokuhlola kuze kube yilapho kwenziwa ukuhlolwa ngakunye okuhlobene kwemishini futhi kuboniswa ukuhambisana nezidingo ezichaziwe
    Kumapayipi e-PSL 2, umenzi kufanele asungule futhi alandele izinqubo ezibhaliwe zokugcina ubunikazi bokushisa kanye nobunikazi beyunithi yokuhlola yalelo payipi. Izinqubo ezinjalo zizohlinzeka ngezindlela zokulandelela noma yibuphi ubude bepayipi liye eyunithi yokuhlola efanele kanye nemiphumela yokuhlolwa kwamakhemikhali ehlobene.
