    • I-Api 5l Line Pipes Ibanga B ukuya ku-X70 Od Ukusuka ku-219mm ukuya ku-3500mm

    Incazelo emfushane:

    Lokhu kushiwo ukuhlinzeka ngezinga lokukhiqiza lesistimu yamapayipi ukuhambisa amanzi, igesi kanye nowoyela ezimbonini zikawoyela negesi yemvelo.

    Kunamazinga amabili wokucaciswa komkhiqizo, i-PSL 1 ne-PSL 2, i-PSL 2 inezidingo eziyisibopho zokulingana kwekhabhoni, ukuqina kwe-notch, amandla aphezulu wokukhiqiza namandla aqinile.

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

    I-Cangzhou Spiral Steel pipes group co., Ltd ihlinzeka ngamapayipi e-SAWH ahlanganisa ibanga ukusuka ku-API B kuya ku-X70, sathola isitifiketi se-API 5L eminyakeni edlule futhi manje amapayipi ethu olayini asetshenziswa kakhulu yi-CNPC, i-CPECC kumaphrojekthi awo wamapayipi.

    Ukuhlolwa kwe-Hydrostatic

    incazelo yomkhiqizo1

    Ipayipi kufanele imelane nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi
    Amajoyinti akudingeki ahlolwe nge-hydrostatically, inqobo nje uma izingxenye zepayipi ezisetshenziswa umaka amajoyinti zihlolwe ngempumelelo nge-hydrostatically ngaphambi kokuhlanganisa.

    Ukulandelela:
    Ngepayipi le-PSL 1, umkhiqizi uzosungula futhi alandele izinqubo ezibhaliwe zokugcinwa:
    Ubunikazi bokushisa kuze kube yilapho kwenziwa ukuhlolwa kwe-chmical ngakunye okuhlobene futhi kuboniswa ukuhambisana nezidingo ezishiwo
    Umazisi weyunithi yokuhlola kuze kube yilapho kwenziwa ukuhlolwa ngakunye kwemishini okuhlobene futhi kuboniswa ukuhambisana nezidingo ezishiwo
    Ngepayipi le-PSL 2, umenzi uzosungula futhi alandele izinqubo ezibhaliwe zokugcina ubunikazi bokushisa kanye nobunikazi beyunithi yokuhlola yalelo payipi.Lezo zinqubo zizohlinzeka ngezindlela zokulandela noma yibuphi ubude bepayipi endaweni yokuhlola efanele kanye nemiphumela yokuhlolwa kwamakhemikhali ehlobene.
