    Ukongeza kwikhabhoni, iityhubhu zethu zomthungo ezijikelezayo ziqulathe ezinye izinto ezibalulekileyo ezifana ne-nickel kunye ne-chromium. I-Nickel yintsimbi ye-ferromagnetic eyongeza amandla kunye nokupholishwa kombhobho. Ukongeza, iyamelana nokugqwala kwaye iqinisekisa ubomi benkonzo obude kwiipayipi zethu. I-Chromium, kwelinye icala, yinto ebalulekileyo kwintsimbi engagqwali kwaye inokumelana nokugqwala okuhle kakhulu. Ukufakwa kwe-chromium kwiipayipi zethu zomthungo ezijikelezayo kwandisa ngakumbi ixesha elide kunye nokuthembeka kwazo.

    Enye yezona nzuzo ziphambili zeepayipi zethu zomthungo ezijikelezayo luyilo lwazo olungenamthungo, olufezekiswa ngetekhnoloji yokudibanisa ephucukileyo. Itekhnoloji yethu yokudibanisa ye-SAWH (Submerged Arc Spiral Welding) yanamhlanje iqinisekisa unxibelelwano oluqinileyo noluhlala ixesha elide phakathi kweepleyiti zentsimbi zepayipi. Le teknoloji yokudibanisa ayiphuculi nje kuphela iimpawu zoomatshini zepayipi, kodwa ikwaqinisekisa umphezulu wangaphakathi ogudileyo, ovumela ukuhamba kakuhle kolwelo okanye iigesi ezahlukeneyo.

    Iipayipi zethu zomthungo ezijikelezayo zisetyenziswa kakhulu kumashishini amaninzi, kuquka ioyile negesi, ukuthuthwa kwamanzi, ulwakhiwo kunye nophuhliso lweziseko. Ingasetyenziswa kwiiprojekthi zaselunxwemeni naselunxwemeni nakwiinkqubo zepayipi ngeenjongo ezahlukeneyo. Ngenxa yokumelana kwayo nokugqwala okugqwesileyo kunye namandla aphezulu okutsalwa, iipayipi zethu lolona khetho luphambili lokuwelda iipayipi kwiindawo ezinzima.

    a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

    KwiCangzhou Spiral Steel Pipe Group Co., Ltd., sibeka umgangatho kunye nolwaneliseko lwabathengi kuqala. Iqela lethu leengcali ezizinikeleyo liqinisekisa ukuba umbhobho ngamnye womthungo ojikelezayo udlula kwiinkqubo zolawulo olungqongqo lomgangatho ukuze uhlangabezane nemigangatho yamazwe ngamazwe. Ukongeza, sinikezela uluhlu olubanzi lweendlela zokugquma imibhobho, kubandakanya i-epoxy, i-polyethylene kunye ne-samente mortar, ukuphucula ngakumbi ukumelana nokugqwala kombhobho kunye nokwandisa ubomi benkonzo yawo.
