    Api 5l Line Pipes Grade B Ukuya X70 Od Ukusuka 219mm ukuya 3500mm Umfanekiso okhoyo
    • I-Api 5l Linemibhobho yeBanga B ukuya kwi-X70 Od ukusuka kwi-219mm ukuya kwi-3500mm

    Inkcazelo emfutshane:

    Oku kuchazwa kukubonelela ngomgangatho wokwenziwa kwenkqubo yemibhobho yokuhambisa amanzi, igesi kunye ne-oyile kumashishini e-oyile negesi yendalo.

    Kukho amanqanaba amabini okucaciswa kwemveliso, i-PSL 1 kunye ne-PSL 2, i-PSL 2 ineemfuno ezinyanzelekileyo zokulingana kwekhabhoni, ukuqina kwenotshi, amandla aphezulu esivuno kunye namandla okuqina.

    IBanga B, X42, X46, X52, X56, X60, X65, X70 kunye neX80.

    I-Cangzhou Spiral Steel pipes group co., Ltd ibonelela ngemibhobho ye-SAWH evala ibakala ukusuka kwi-API B ukuya kwi-X70, safumana isiqinisekiso se-API 5L kwiminyaka eyadlulayo kwaye ngoku imibhobho yethu yomgca esetyenziswa ngokubanzi yi-CNPC, i-CPECC kwiiprojekthi zabo zemibhobho.

    Uvavanyo lweHydrostatic

    imveliso-inkcazo1

    Umbhobho uya kumelana novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld okanye umzimba wombhobho
    Izihlanganisi akufuneki zivavanywe nge-hydrostatically, ngaphandle kokuba iindawo zombhobho ezisetyenzisiweyo ekuphawuleni izihlanganisi ziye zavavanywa ngempumelelo nge-hydrostatically phambi komsebenzi wokudityaniswa.

    Ukulandelelwa:
    Ngombhobho we-PSL 1, umenzi uya kuseka kwaye alandele iinkqubo ezibhaliweyo zokugcina:
    Isazisi sobushushu de kwenziwe uvavanyo ngalunye olunxulumeneyo lwechmical kwaye ukuhambelana neemfuno ezichaziweyo kubonisiwe
    Isazisi seyunithi yovavanyo de kwenziwe uvavanyo lomatshini ngalunye olunxulumeneyo kunye nokuhambelana neemfuno ezichaziweyo
    Ngombhobho we-PSL 2, umenzi uya kuseka kwaye alandele iinkqubo ezibhaliweyo zokugcina isazisi sobushushu kunye nesazisi seyunithi yovavanyo lwaloo mbhobho.Ezo nkqubo ziya kubonelela ngeendlela zokulandela nabuphi na ubude bombhobho kwiyunithi yovavanyo efanelekileyo kunye neziphumo zovavanyo lweekhemikhali ezinxulumeneyo.
