Amandla aphezulu kunye nokuqina
Ngokwenxa yeI-API 5Lumgangatho (umgangatho we-American Petroleum Institute), amandla okutsalwa kwe-GR.B grade ≥414MPa, amandla okukhupha i-≥241MPa, ifanelekile kwindawo enoxinzelelo oluphezulu, kunye noxinzelelo oluphezulu (njengokuthuthwa kweoyile negesi).
Inkqubo engenamthungo ayinabuthathaka bokuwelda, ukumelana nokucinezelwa okunamandla kunye nokuguquguquka, ifanelekile ngakumbi kwiimeko ezinzima zejoloji (ezifana nentlango yaseMbindi Mpuma, imibhobho yamanzi angaphantsi komhlaba).
Ukumelana nokugqwala okugqwesileyo
Ukumelana nokugqwala kunokuphuculwa ngokongeza izinto ezincinci (ezifana neCr, Mo) okanye unyango lokugquma, ukuze zilungelelane nendawo enetyuwa eninzi kuMbindi Mpuma okanye imozulu efumileyo eYurophu.
Ukuchaneka okuphezulu kunye nokuhambelana
Umbhobho wentsimbi ongenamthungo unobume obuphezulu bokuchaneka (ubukhulu bodonga obufanayo, ukujiya okuncinci), kulula ukuwelda nokufakela, kunye neengozi zobunjineli ezincitshisiweyo.
Ukusetyenziswa ngokubanzi
Ingasetyenziselwa ukuthutha iintlobo ngeentlobo zezinto ezifana neoyile, igesi yendalo, amanzi, njl.njl., kwaye ingasetyenziselwa inkxaso yesakhiwo (njengezakhiwo, iibhulorho), ukuhlangabezana neemfuno ezahlukeneyo.
1. Izinto ezithandwa yimarike yaseYurophu
Ukuthobela ngokungqongqo umgangatho omiselweyo:
Umgangatho we-API5L uyahambelana ne-European EN 10208, i-ISO 3183 kunye nezinye iinkcukacha. I-PSL1 GR.B inokuhlangabezana neemfuno ezisisiseko kwaye ixabisa kancinci kune-PSL2 (iimfuno zovavanyo eziphezulu), kwaye inexabiso eliphezulu.
Imfuno yeziseko zophuhliso zamandla:
Utyalo-mali oluqhubekayo lwaseYurophu kwimibhobho yeoyile negesi (ingakumbi amasimi eoyile negesi aseNorth Sea, iinethiwekhi zothumelo lwegesi eMpuma Yurophu) kunye namandla avuselelekayo (njengemibhobho yehydrogen) luqhuba imfuno.
Ukhuseleko lokusingqongileyo kunye nokuzinza:
Imibhobho yentsimbi engenamthungo ihlala ixesha elide kwaye ayinabungozi kangako bokuvuza, ihlangabezana neemfuno zokunciphisa ukukhutshwa komoya eYurophu.
2. Izinto ezithandwa yimarike yaseMbindi Mpuma
Ukuxhomekeka kwishishini leoyile negesi:
UMbindi Mpuma ubangela ngaphezulu kwe-30% yemveliso yeoyile yehlabathi. I-API5L GR.B yeyona nto ikhethwayo kwimibhobho yaselwandle nakwimibhobho engaphantsi kwamanzi, ifanelekile kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.
Imfuno yokwandiswa kweziseko zophuhliso:
"Umbono ka-2030" waseSaudi Arabia kunye nesicwangciso sokwahlukahluka kwe-UAE zikhuthaza ukwakhiwa kwenethiwekhi zemibhobho, izityalo zokukhupha ityuwa, kunye nezikhululo zamandla, kwaye imfuno yemibhobho yentsimbi engenamthungo inamandla.
Uzinzo lweendleko kunye nobonelelo:
Ixabiso leI-API5L GR.BImibhobho yentsimbi engenamthungo eveliswa eTshayina iphantsi ngama-20%-30% kuneyabavelisi baseYurophu naseMelika, kwaye umjikelo wokuhambisa umfutshane. Abathengi baseMbindi Mpuma badla ngokuthenga ixesha elide.
Iimfuno zesatifikethi: Ukuqinisekiswa kwe-CE okanye ukuthotyelwa kwe-PED (Pressure Equipment Directive), ukubonelela ngeengxelo ze-CBAM, ze-EPD, njl.
Imiqobo yorhwebo: Nikela ingqalelo kwimigaqo-nkqubo yerhafu. Kutshanje, i-EU iye yaphelisa umgaqo-nkqubo wayo wokulwa nokulahla inkunkuma kwimibhobho yentsimbi engenamthungo yaseTshayina
Ngokudibanisa iingenelo zokusebenza, ukukhuphisana ngeendleko kunye nemfuno yemarike, imibhobho yentsimbi engenamthungo ye-API5L PSL1 GR.B iyaqhubeka nokuba kwindawo ebalulekileyo kwimarike yase-Eurasia.
