    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.

    Umjelo woGutyulo

    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.

    Enye yeenzuzo eziphambili zombhobho we-SSAW kukuguquguquka kwayo kokuvelisa.Le mibhobho inokuveliswa kwiintlobo ezahlukeneyo zobukhulu, ububanzi kunye nobukhulu kwaye ingenziwa ngokwezifiso ukuhlangabezana neemfuno zeprojekthi ethile.Ukongeza, imibhobho edityanisiweyo ye-arc edityanisiweyo ye-spiral idla ngokwenziwa ngentsimbi ekumgangatho ophezulu, iyenza ikwazi ukumelana nomhlwa kwaye iqinisekise ubomi obude benkonzo.

    API 5L Line Umbhobho:

    Umbhobho womgca we-API 5Lngumbhobho wolwakhiwo wecandelo elinomngxuma osetyenziswa ngokubanzi odibana nemigangatho yeAmerican Petroleum Institute (API).Le mibhobho yenzelwe ukuthutha ulwelo, njengeoyile negesi yendalo, kwimigama emide.Umbhobho womgca we-API 5L uyaziwa ngamandla ayo aphezulu, ukuqina kunye nokuchasana neemeko ezinzima zokusingqongileyo.

    Inkqubo yokuvelisa i-API 5L yomgca wombhobho ibandakanya amanyathelo okulawula umgangatho ongqongqo ukuqinisekisa ukuthembeka kwayo.Le mibhobho yenziwe ngentsimbi ye-carbon kwaye ineempawu ezibalaseleyo zoomatshini.Ukuthotyelwa okungqongqo kwimigangatho ye-API kuqinisekisa ukuba le mibhobho inokumelana noxinzelelo oluphezulu kunye nokutshintsha kweqondo lokushisa, okwenza kube yinto efanelekileyo kwizicelo ezibalulekileyo kwishishini leoli kunye negesi.

    Uncedo oludibeneyo:

    Xa i-spiral submerged arc welded pipe kunye ne-API 5L yombhobho womgca idityanisiwe, ibonelela ngokuthembeka kwesakhiwo esingenakulinganiswa kunye nokuthembeka.I-spiral seams yombhobho we-SSAW idityaniswe namandla kunye nokuqina kwe-API 5L yombhobho womgca wenza inkqubo eyomeleleyo yenkxaso yesakhiwo.

    Ukongeza kwiinzuzo zabo, ukuhambelana kombhobho we-arc welding we-spiral odibeneyo kunye ne-API 5L yombhobho womgca kwandisa ukusebenza kakuhle kweeprojekthi zemibhobho.Ukuguquguquka kombhobho we-SSAW kuvumela ukudibanisa okulula kunye ne-API 5L yombhobho womgca, ukuqinisekisa ukuhamba ngokungenamthungo kwamanzi ngaphakathi kwenethiwekhi yombhobho.

    Ukuququmbela:

    Imibhobho yolwakhiwo lwecandelo elingenamgobo ibaluleke kakhulu xa kusakhiwa iziseko ezingundoqo ezomeleleyo.Ukusetyenziswa okudibeneyo kombhobho we-SSAW kunye ne-API 5L yombhobho womgca unika isisombululo esinamandla esinika amandla, ukuqina kunye nokuthembeka kwiiprojekthi ezahlukeneyo.Nokuba ixhasa iziseko zezakhiwo ezide okanye ukuthutha ulwelo olubalulekileyo kumgama omde, le mibhobho idlala indima ebalulekileyo ekuqinisekiseni ubude kunye nokuzinza kweziseko zophuhliso zethu.Ngokusebenzisa amandla e-spiral arc welded welded pipe kunye nokuthembeka kombhobho womgca we-API 5L, iinjineli zinokukha isiseko esiluqilima sengomso elingcono.
