a.Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:
FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).
b.Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding.Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

Ukongeza, ekukhuseleni umliloimibhobho, ukusetyenziswa kwe-spiral seam welded imibhobho kubalulekile ukuqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo.Le mibhobho yenzelwe ngokukodwa ukumelana nokushisa okuphezulu kunye noxinzelelo kwaye ifanelekile ukusetyenziswa kwiinkqubo zokukhusela umlilo.Ulwakhiwo oludityanisiweyo lombhobho we-spiral seam luqinisekisa ukuba aluvuzi kwaye lugcina ingqibelelo yesakhiwo naphantsi kweemeko ezinzima, okwenza kube yinto ebalulekileyo yokukhusela umlilo kunye neenkqubo zokucima umlilo.

Enye yeenzuzo eziphambili zespiral umthungo welding umbhobhokukuguquguquka kwayo kunye nokuziqhelanisa neentlobo ngeentlobo zezicelo.Le mibhobho inokuveliswa kwiintlobo ezahlukeneyo zeedamitha kunye nobukhulu ukuhlangabezana neemfuno ezithile zeprojekthi.Ukongeza, zinokugqunywa ngezinto ezikhuselayo zokuphucula ukuxhathisa ukubola kunye nokwandisa ubomi babo benkonzo, zibenze zilungele ukusetyenziswa kwiindawo ezahlukeneyo kunye neemeko.

Imibhobho edityanisiweyo ye-Spiral seam ineenzuzo ezicacileyo xa kufikwa kufakelo nokugcinwa.Zikhaphukhaphu kwaye ziguquguquka, zenza kube lula ukuthutha nokuphatha, ukunciphisa ixesha lofakelo kunye neendleko zabasebenzi.Ukongezelela, ubude bayo obude, obuqhubekayo bunciphisa imfuno yokudibanisa okongeziweyo, ukunciphisa umngcipheko wokuvuza kunye nokuqinisekisa inkqubo yombhobho esebenzayo kunye nethembekileyo.

Ukuqukumbela, i-spiral seam welded pipe licandelo elibalulekileyo kumashishini ahlukeneyo, ngakumbi kwizakhiwo ezidityanisiweyo ezibandayo kunye.umgca wombhobho womliloizicelo.Ukwakhiwa kwayo okuhlala ixesha elide, ukusebenza okuphezulu kunye nokuguquguquka kwenza kube lukhetho lokuqala kwiinjineli, iikontraka kunye nabaphathi beprojekthi.Ingaba ukwakha izakhiwo ezomeleleyo okanye ukuyila iinkqubo ezikhuselekileyo nezithembekileyo zokukhusela umlilo, i-spiral seam welded imibhobho sisisombululo esiyimfuneko kwiimfuno zeziseko zophuhliso zanamhlanje kunye noshishino.
