    Inkcazo ye-API 5L yoHlelo lwama-46 lweSikhundla seMibhobho yoMgca

    Inkcazo ye-API 5L yoHlelo lwama-46 loMfanekiso oPhambili wePipe yoMgca
    • Inkcazo ye-API 5L yoHlelo lwama-46 lweSikhundla seMibhobho yoMgca

    Inkcazo emfutshane:

    Kuchazwe ukwenziwa kwamanqanaba amabini emveliso (i-PSL1 kunye ne-PSL2) yombhobho wentsimbi ongenamthungo nowelding wokusetyenziswa kombhobho ekuthuthweni kwepetroliyam kunye negesi yendalo. Ukusetyenziswa kwezinto kwisicelo senkonzo yeSour jonga kwiSihlomelo H kwaye kwisicelo senkonzo yaselwandle jonga kwiSihlomelo J se-API5L 45th.

    Ulwazi loku-odola

    I-odolo yokuthenga iya kuquka ubungakanani, inqanaba le-PSL, uhlobo okanye iBanga, isalathiso se-API5L, ububanzi bangaphandle, ubukhulu bodonga, ubude kunye nazo naziphi na izihlomelo ezifanelekileyo okanye iimfuno ezongezelelweyo ezinxulumene nokwakheka kweekhemikhali, iimpawu zoomatshini, unyango lobushushu, uvavanyo olongezelelweyo, inkqubo yokuvelisa, ukugquma komphezulu okanye ukugqitywa kokuphela.

    I-HFW – Umbhobho odityanisiweyo ophindaphindwayo, >70 kHz

    I-SAWL – Ukuwelda okufakwe phantsi komhlaba nge-arc welded longitudinal

    I-SAWH – Ukuwelda nge-submerge-arc welded nge-helical weld

    Izinto Zokuqala

    Iingots, iintyatyambo, iibhilethi, iikhoyili okanye iipleyiti ezisetyenziselwa ukwenza umbhobho kufuneka zenziwe ngezi nkqubo zilandelayo, ioksijini esisiseko, isithando sombane okanye iziko elivulekileyo kunye nenkqubo yokucocwa kweladle. KwiPSL2, intsimbi kufuneka ibulawe kwaye inyibilikiswe ngokwesiko lengqolowa entle. Ikhoyili okanye ipleyiti esetyenziselwa umbhobho wePSL2 akufuneki ibe nazo naziphi na ii-welds zokulungisa.

    Uvavanyo lwe-Hydrostatic

    Umbhobho omele umelane novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld okanye umzimba wombhobho. Akunyanzelekanga ukuba ii-jointers zivavanywe nge-hydrostatic ukuba nje iindawo zombhobho ezisetyenzisiweyo zivavanywe ngempumelelo.

    Uvavanyo lwe-Bend

    Akukho mifantu iya kwenzeka nakweyiphi na inxalenye yesixhobo sovavanyo kwaye akuyi kubakho kuvulwa kwe-weld.

    Uvavanyo lokuTyatya

    Iikhrayitheriya zokwamkelwa kovavanyo lokuthamba kufuneka zibe
    a)Iipayipi ze-EW D<12.750 intshi
    -≥ X60 ene-T≥0.500in, akufuneki kubekho kuvulwa kwe-weld ngaphambi kokuba umgama phakathi kweepleyiti ube ngaphantsi kwe-66% yobubanzi bokuqala bangaphandle. Kuzo zonke iiklasi kunye nodonga, yi-50%.
    -Kwipayipi ene-D/t > 10, akufuneki kubekho kuvulwa kwe-weld ngaphambi kokuba umgama phakathi kweepleyiti ube ngaphantsi kwe-30% yobubanzi bangaphandle bokuqala.
    b) Ukuba ufuna ezinye iisayizi, jonga iinkcukacha ezipheleleyo ze-API5L

    Uvavanyo lwempembelelo ye-CVN kwi-PSL2

    Iipayipi ezininzi zePSL2 ezinobukhulu kunye neegreyidi zifuna iCVN. Iipayipi ezingenamthungo kufuneka zivavanywe emzimbeni. Iipayipi ezidityanisiweyo kufuneka zivavanywe kwiBody, iPipe Weld kunye nendawo echaphazelekileyo kubushushu (HAZ). Jonga iinkcukacha ze-API5L ezipheleleyo kwitshathi yobukhulu kunye neegreyidi kunye namaxabiso amandla afunekayo.
