Umbhobho we-LSAW (Longitudial Submerged Arc Welding)

I-LSAW (Ukuwelda kwe-Arc engaphantsi komhlaba eLongitudinal):Oku kubhekisa kwinkqubo yokuvelisa.

I-Longitudinal: Umthungo we-weld uhamba ngaxeshanye nobude bombhobho (ngomgca othe tye). Oku kwahlukile kwi-HSAW/SSAW (Helical/Spiral Submerged Arc Welding), apho i-weld ijikeleza khona.

Ukuwelda kwe-Arc engaphantsi komhlaba (SAW): Inkqubo yokuwelda esemgangathweni ophezulu apho i-arc ifakwa phantsi komaleko we-fusible flux. Oku kuvumela ukungena kobushushu obunzulu, kudala ukuwelda okuqinileyo, okufanayo, kwaye kuvelisa ukugqitywa okugudileyo ngaphandle kokuchitha.

Umthungo Othe Tye Omacala Amabili:Oku kuchaza iimpawu zomzimba ze-weld.

Umbhobho wenziwe ngepleyiti enye yentsimbi (i-skelp) eqengqwe yaya kwisilinda, nto leyo eyenza umthungo omnye othe tye.

Icala Eliphindwe Kabini: I-weld yenziwa ngaphakathi nangaphandle kombhobho. Oku kubaluleke kakhulu kuba kuqinisekisa ukuba i-weld isemgangathweni ophezulu kakhulu, nto leyo eyenza ukuba ikwazi ukusingatha uxinzelelo oluphezulu kunye nokusetyenziswa okunzima.

Iipayipi zentsimbi ze-LSAW Izicelo eziphambili

Udidi lweSicelo	Iindlela Ezithile Zokusebenzisa	Kutheni i-LSAW isetyenziswa
Imibhobho yeoyile negesi eselunxwemeni/elunxwemeni	Iipayipi zokuhambisa ioyile ekrwada, igesi yendalo, kunye neemveliso ezicociweyo.	Iphatha uxinzelelo lwangaphakathi oluphezulu kakhulu, imelana noxinzelelo lwangaphandle, kwaye inokugqunywa ukuze ikhusele ukugqwala kwiindawo ezirhabaxa.
Iinkonzo zoXinzelelo oluPhezulu	Umphunga oxinzelelweyo ophezulu, imijelo yokutya yamakhemikhali, kunye nokuthuthwa kodaka.	Ulwakhiwo oluqinileyo lunokumelana noxinzelelo oluqhubekayo nolunzima ngaphandle kokusilela.
Izakhiwo zaseLwandle kunye nokuHlanganisa	Ukufakwa kweziseko zeebhulorho, amazibuko, kunye namaqonga aselunxwemeni.	Iindonga ezinkulu nobukhulu bazo zibonelela ngenkxaso enkulu yesakhiwo kunye nomthamo wokuthwala umthwalo. Zihlala zibethelelwa nzulu emhlabeni.
Ubunjineli boLwakhiwo kunye noLwakhiwo	Iikholamu zezakhiwo eziphakamileyo, izitediyam, kunye nezakhiwo ezinkulu.	Isetyenziswa njenge "iintsika zepayipi" ezizaliswe yikhonkrithi (i-CFST) ukubonelela ngamandla amangalisayo kunye nozinzo kwisakhiwo esiphambili.
Ukuhanjiswa kwamanzi	Iipayipi zamanzi ezinkulu kunye neepenstocks zezityalo zamandla ombane ngamanzi.	Iyakwazi ukuhambisa amanzi amaninzi phantsi koxinzelelo oluphezulu.

Kutheni iipayipi ze-LSAW zikhethwa kwizicelo eziphezulu

Amandla aphezulu kunye noVavanyo loxinzelelo:Inkqubo ye-SAW enamacala amabini idala i-weld enamandla njenge, okanye enamandla kunentsimbi esisiseko ngokwayo. Oku kuyenza ilungele ukusetyenziswa ngoxinzelelo oluphezulu.

Ububanzi obukhulu kunye neendonga ezityebileyo:Iipayipi ze-LSAW zinokwenziwa ngobubanzi obukhulu kakhulu (ngesiqhelo ukusuka kwiisentimitha ezili-16 ukuya kuthi ga kwiisentimitha ezingama-60 nangaphezulu) kwaye zinodonga oluqinileyo kakhulu, into engenakwenzeka ngeenkqubo ezincinci zepayipi ezifana ne-ERW (Electric Resistance Welding).

Ukuchaneka Okugqwesileyo Kwemilinganiselo:Zinobukhulu obufanayo kunye nokujikeleza okulinganayo, nto leyo ibalulekileyo ekwakhiweni kwemibhobho kunye neeprojekthi zesakhiwo.

Ilungele ukugqunywa:Umthungo wazo othe tye kunye nomphezulu ogudileyo kuzenza zilungele ngokupheleleyo ukufaka izinto ezahlukeneyo zokukhusela (ezifana ne-FBE Fusion Bonded Epoxy, 3LPE/3LPP) kunye nee-linings (umz., uphahla olunobunzima bekhonkrithi kwiipayipi zaselwandle). Umphezulu ogudileyo nohlala uhleli uqinisekisa ukuba uphahla lunamathela ngokufanelekileyo kwaye lwenza umsebenzi walo wokukhusela.
