Umbhobho wentsimbi we-LSAW, isifinyezo seLongitudinal Submerged Arc Welded pipe kwaye ikwabizwa ngokuba yiUmbhobho we-SAWL, yenziwe ngeepleyiti zentsimbi eziqinileyo. Uninzi lwemveliso yorhwebo lulandela indlela yokwenza i-JCOE: iipleyiti ezingavuthwanga kuqala zigaywa ngomphetho ochanekileyo, emva koko zenziwa ngokubandayo zibe yiprofayili yesilinda ngokusebenzisa izigaba ze-J-forming ezilandelelanayo, i-C-forming kunye ne-O-forming, ngaphambi kokuba zifumane i-arc welding yangaphakathi neyangaphandle engaphantsi kwamanzi. Ukugqitywa kwe-post-weld kubandakanya ubungakanani, ukuqiniswa koomatshini, ukubethelwa kwesiphelo kunye nokuqinisekiswa komgangatho opheleleyo.
Olu yilo lwe-weld olusekelwe kwipleyiti, oluthe tye lubonelela ngeenzuzo ezisisiseko zokufana kwe-weld, ukuhambelana kweempawu zoomatshini kunye nokuthembeka kwesakhiwo. I-weld seam ihamba ngaxeshanye ne-axis yombhobho, ngobude obufutshane be-weld iyonke kwicandelo ngalinye le-standard pipe, nto leyo enciphisa umngcipheko wezibalo oqokelelweyo weziphene ze-weld.
Umbhobho we-LSAWIinkcukacha kunye nokusebenza
Uluhlu lobubanzi obungaphandle:Imveliso eqhelekileyo isusela kwi-16 intshi (406 mm) ukuya kwi-60 intshi (1,524 mm), kwaye ubungakanani obulungiselelwe wena bufumaneka kwiiprojekthi zobunjineli ezikhethekileyo.
Ubuchule bokutyeba kodonga:Ixhasa imveliso yodonga olunzima ukuhlangabezana neemfuno ezinamandla aphezulu, ezinoxinzelelo oluphezulu, kunye nemida yobukhulu edlula kakhulu leyo ye-ERW kunye nezinye iindlela ze-spiral welded.
Amandla aphambili okusebenza:Ukumelana okugqwesileyo koxinzelelo lwangaphakathi, ukomelela okuphezulu kobushushu obuphantsi, ukunyamezelana okuqinileyo nokuthe tye, kunye nokuxinana okuthembekileyo kokuvuza phantsi komthwalo ojikelezayo.
Izicelo eziphambili ze-LSAW Pipe
Umbhobho we-LSAW ngumgangatho weshishini kwiindlela ezibalulekileyo zokuhambisa ioyile negesi, ingakumbi iindlela ezinde ezinqumla iindawo zasezidolophini ezinabantu abaninzi, iindlela zamanzi ezingaphakathi elizweni, iindawo zaselwandle kunye neendawo ezikhuselweyo ngokwendalo. Ngokweenkcukacha zoyilo lombhobho we-API 5L, uvunyiwe ngokupheleleyo kwiiklasi zendawo zeKlasi 1 kunye neKlasi 2 apho ukhuseleko loluntu kunye nokuthembeka kokusebenza kungaxoxiswana ngako.
Ngaphaya kwecandelo lamandla, ichazwe ngokubanzi kwiimeko zokusetyenziswa kwezakhiwo ezinzima kunye nezixhobo, kubandakanya ukufakwa kweebhulorho ezithwala umthwalo, iipayipi zokuhambisa amanzi amaninzi, imibhobho yenkqubo yesityalo samandla obushushu kunye neenkqubo zoshishino ezifuna amandla aphezulu ezakhiwo kunye neminyaka emininzi yobomi benkonzo.
