    I-API 5L 46 ye-Edition yoHlelo loMbhobho wePing

    I-API 5L 46 ye-Edition yoshicilelo lombhobho wombhobho obonisiweyo
    • I-API 5L 46 ye-Edition yoHlelo loMbhobho wePing

    Inkcazo emfutshane:

    Ichaziwe ekwenzeni amanqanaba amabini emveliso (i-PSL1 kunye ne-pll2) yombhobho wentsimbi engenamthungo wokusetyenziswa kombhobho kwi-petroleum nakwigesi yendalo. Ukusetyenziswa kwezinto ezibonakalayo kwisicelo senkonzo yeziBonelelo kubhekisa kwi-ANNEX H kunye nesicelo senkonzo ye-offshore sinika i-annex j ye-api5l 45.

    Ukuqala kwezinto

    I-Ingots, iibhlokhi, ii-billets, iiplate okanye iipleyiti ezisetyenziselwa ukwenziwa kombhobho ziya kwenziwa kwezi nkqubo zilandelayo, kwiziko lombane okanye i-vem yombane okanye i-vem yenqeni evulekileyo. I-Psl2, intsimbi iya kubulawa, inyibilike ngokwemisebenzi yokudla okuziinkozo. I-Coil okanye iplate esetyenziselwa umbhobho we-PSL2 ayiyi kuba nayo nayiphi na i-welds.

    Uvavanyo lwe-hydrostatic

    Umbhobho wokumelana novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-wel okanye umzimba wombhobho. Amajoyine akufuneki ukuba avavanywe i-hydrostatic ukubonelela ngamacandelo emibhobho esetyenzisiweyo avavanywa ngempumelelo.

    Uvavanyo lwe-Bend

    Akukho zibuko ziya kwenzeka nakweyiphi na inxalenye yesiqwenga sovavanyo kwaye ayivumi ukuba i-weld iya kwenzeka.

    Uvavanyo lokungafihli

    Iikhrayitheriya zokwamkelwa kovavanyo lokuthambeka luya kuba
    a) imibhobho ye-ew d <12.750 kwi
    -≥ x60 nge-T≥0.500in, akuyi kubakho kuvulwa kwe-weld ngaphambi komgama phakathi kweepleyiti zingaphantsi kwe-66% yedayiti yangaphandle. Kuwo onke amabakala nodonga, iipesenti ezingama-50.
    -Ukwenziwe nge-D / T> 10, Akuyi kubakho kuvulwa kwe-weld ngaphambi komgama phakathi kweepleyiti zingaphantsi kwe-30% yobubanzi bentsusa.
    b) Obunye ubukhulu bhekisa kwi-API5l ye-API5l

    Uvavanyo lwempembelelo ye-CVN ye-PSL2

    Uninzi lwemibhobho ye-PSL2 ye-PSL2 kunye namaBanga afunekayo kwi-CVn. Umbhobho ongenamthungo uza kuvavanywa emzimbeni. Umbhobho we-Weldied kufuneka uvavanywe emzimbeni, i-pipe wel kunye nobushushu obuchaphazelekayo (i-HAZ). Jonga kwi-API5L epheleleyo ye-API5L yeTshathi yobukhulu kunye namaBakala kwaye ifuneke amaxabiso anemilinganiselo yamandla.
