    Inkqubo yokwenziwa kweA252 Grade 3 umbhobho yentsimbiibandakanya ukwenza i-spiral weld eqhubekayo ngobude bombhobho, okukhokelela kwisakhiwo esomeleleyo, esingenamthungo.Obu buchule bokwakha buphucula amandla ombhobho ukusabalalisa ngokulinganayo uxinzelelo kunye nokuxhathisa ukuguqulwa, okwenza kube yinto efanelekileyo yofakelo oluphantsi komhlaba.Ukongezelela, umbhobho uhlanganiswe nengubo yokukhusela eyongeza ngakumbi ukuchasana kwayo nokugqwala kunye nokugqoka, ukuqinisekisa ubomi obude benkonzo kwizicelo zombhobho.

    Umbhobho wentsimbi i-A252 yeBanga lesi-3 yenzelwe ukuhlangabezana neemfuno ezithile zokwakhiwa kwemibhobho yogutyulo, njengokubonelela ngombhobho othembekileyo wamanzi amdaka kunye nogutyulo, kunye nokumelana nomhlaba kunye nemithwalo yezithuthi ngaphezulu kwawo.Iimpawu eziphezulu zamandla emibhobho yensimbi zivumela ukuba zigcine ingqibelelo yesakhiwo naphantsi kweemeko ezinzima, ngaloo ndlela zinciphisa umngcipheko wokuvuza, ukuwa kunye nezinye iindlela zokungaphumeleli kweziseko zophuhliso.

    Ukongeza kwiipropathi zayo zemishini, i-A252 yeBanga lesi-3 lombhobho wensimbi inika inzuzo engabizi kakhulu kwiiprojekthi zogutyulo.Kulula ukuyifaka, ineemfuno zokugcinwa okuphantsi kwaye inobomi benkonzo ende, inceda ukugcina iindleko ezipheleleyo kubomi beziseko zophuhliso.Ukongezelela, ukuhambelana kombhobho kunye neendlela ezahlukeneyo zokudibanisa kunye nezixhobo zivumela ulwakhiwo oluguquguqukayo nolusebenzayo oluhlangabezana neemfuno ezithile zomnatha womnatha.

    Umbhobho woMda waManzi angaphantsi komhlaba

    Iikontraka zogutyulo kunye neenkampani zobunjineli zinokuzuza ekusebenzeni okuphezulu kwe-A252 yeBanga lesi-3 lombhobho wentsimbi kwiiprojekthi zabo njengoko ibonelela ngesisombululo esithembekileyo nesihlala ixesha elide sokuthuthwa kwamanzi amdaka aphantsi komhlaba.Ngokukhetha izinto ezisemgangathweni ezifana ne-A252 yeBanga lesi-3 lombhobho wensimbi, banokuqinisekisa ukusebenza kwexesha elide kunye nokuqina kweenkqubo zabo zogutyulo, ukunciphisa umngcipheko wokulungiswa kweendleko kunye nokuphazamiseka kwenkonzo.

    Isishwankathelo, i-A252 grade 3 ipayipi yensimbi ineenzuzo zamandla aphezulu, ukuxhathisa ukubola, kunye nokusebenza kweendleko eziphezulu, okwenza kube lukhetho oluhle kakhulu lokwakhiwa kwemibhobho yelindle.Ulwakhiwo lwayo olungenamthungo kunye noluqilima, kunye nokuthotyelwa neenkcukacha zemibhobho ye-API 5L, kuyenza ibe sisisombululo esithembekileyo nesesigxina sokuthuthwa kwamanzi amdaka angaphantsi komhlaba.I-A252 yeBanga lesi-3 lombhobho wensimbi iyakwazi ukumelana neemeko ezinzima phantsi komhlaba kunye nokubonelela ngokusebenza kwexesha elide, okwenza kube yinto ekhethiweyo kwiiprojekthi zeziseko zogutyulo.
