Ipayipi lensimbi le-LSAW elifakwe ngaphansi kwamanzi isikhathi eside
I-LSAW (ipayipi elishiselwe elingaphansi kwamanzi elingaphansi kwe-arc)ikhiqizwa kusetshenziswa ipuleti elilodwa eliwugqinsi olumaphakathi njengento eluhlaza, bese ucindezela (ukugingqa) ipuleti lensimbi libe ishubhu elingenalutho esikhunjeni noma emshinini wokubumba, lisebenzisa indlela yokushisela i-arc enezinhlangothi ezimbili engaphansi kanye nokwandisa ububanzi.Uhla lokucaciswa komkhiqizo walo lubanzi, ukuqina, ipulasitiki, ukufana nokubumbana kwe-weld seam kuhle.Inezinzuzo zobubanzi obukhulu, ukujiya kodonga oluwugqinsi, ukumelana nengcindezi ephezulu, ukumelana nokushisa okuphansi kanye nokumelana nokugqwala okuqinile.Lapho wakha amapayipi anamandla aphezulu, aqine kakhulu, ekhwalithi ephezulu kawoyela negesi amabanga amade, iningi lamapayipi ensimbi adingekayo amapayipi amakhulu anezindonga eziwugqinsi we-LSAW.
I-LSAW (Longitudinal double submerge arc welding) ipayipi lensimbi ye-carboniwuhlobo lwepayipi le-SAW elenziwe ngamapuleti ensimbi ayeshisa egoqwe yi-JCOE noma i-UOE yokwakha ubuchwepheshe.
Ipayipi le-LSAW lisetshenziselwa ukudlulisa uketshezi olunomfutho ophansi noma i-petroleum enomfutho ophezulu noma igesi yemvelo ukuthutha amabanga amade futhi ingasetshenziswa kabanzi ekusekeleni noma ezisekelweni zesakhiwo.
Ngokusekelwe ekuzuzeni kwayo ukuthembeka okuphezulu nokusebenza kokuphepha, ipayipi le-LSAW lisetshenziswa kabanzi kumapayipi ahlukahlukene wobunjiniyela nokwakhiwa, ngisho nangaphansi kwesimo esinzima kakhulu, futhi lingasetshenziswa kubunjiniyela bemboni yamakhemikhali, amandla kagesi, ukuchelela, ukwakhiwa nokunqwabelanisa. njll. Ubuhle bepayipi le-LSAW lepayipi likawoyela negesi: khiqiza amapayipi aminyene kakhulu, afinyelela ku-120mm.
Izici: Amapayipi ensimbi amakhulu amakhulu, izindonga eziminyene, ukumelana nokucindezela okuphezulu.
