Iimveliso zensimbi ezingenasici zisetyenziswa ngokubanzi kumashishini amaninzi kunye nezicelo ngenxa yokusebenza kakuhle kunye neepropati.Namhlanje, siza kuxoxa umbhobho wentsimbi engenamthungo kunye ne-ERW umbhobho wensimbi engenasici, kunye nomahluko phakathi kweemveliso ezimbini.
Kukho iiyantlukwano phakathi kombhobho wentsimbi ye-ERW kunye nombhobho wentsimbi engenamthungo.I-ERW Pipe imfutshane kwi-Electric Resistance Welding.Isetyenziselwa ukuthutha ulwelo olunjengamafutha, iigesi, njl., kungakhathaliseki ukuba luxinzelelo, kwaye ludlala indima ebalulekileyo kwimibhobho emhlabeni jikelele.Kwangaxeshanye, ngumbhobho wentsimbi ongenamthungo.Imibhobho yentsimbi yesikwere kunye noxande ngaphandle kwamalungu kunye neeprofayili ezingenanto zisetyenziselwa ukuthuthwa kolwelo ngenxa yokugoba kwazo okuphezulu kunye namandla okubetha, kunye nokwenziwa kwezakhiwo kunye neenxalenye zoomatshini.Ngokubanzi, iipayipi ze-ERW kunye nemibhobho yensimbi engenamthungo isetyenziselwa iinjongo ezahlukeneyo.
Imibhobho yentsimbi engenamthungo eyenziwe ngeebhilithi ezingqukuva, ngelixa i-ERW imibhobho yensimbi engenasici iyenziwa kwiikhoyili ezishushu eziqengqelekayo.Nangona izinto ezimbini eziluhlaza zihluke ngokupheleleyo, kufuneka kuqatshelwe ukuba umgangatho wemveliso yokugqibela - imibhobho ixhomekeke ngokupheleleyo kule miba mibini - ukulawulwa komgangatho ngexesha lokuvelisa kunye nemeko yokuqala kunye nomgangatho wezinto eziphathekayo.Zomibini iibhobho zenziwe ngensimbi engenasici yamabakala ahlukeneyo, kodwa eyona nto ixhaphake kakhulu ngumbhobho owenziwe ngetsimbi engama-304.
I-billet ejikelezileyo ishushu kwaye ityhalelwe kwintonga enemingxuma ide ithathe ubume obungenanto.Emva koko, ubude kunye nobukhulu babo bulawulwa ngeendlela zokukhupha.Kwimeko yokuveliswa kwemibhobho ye-ERW, inkqubo yokuvelisa ihluke ngokupheleleyo.Umqulu ugobile kwicala le-axial, kwaye imiphetho eguqukayo idityaniswe kunye nobude bayo bonke ngokuxhathisa i-welding.
Iityhubhu zentsimbi ezingenamthungo zihlanganiswe ngokupheleleyo kumgca wendibano kwaye zifumaneka kwi-OD ukuya kwi-intshi ezingama-26.Kwelinye icala, kwanezona nkampani zentsimbi ziphambili ngetekhnoloji ye-ERW zinokufikelela kuphela ngaphandle kwe-intshi ezingama-24.
Ekubeni imibhobho engenamthungo ikhutshiwe, ayinayo i-joints kwi-axial okanye i-radial direction.Imibhobho ye-ERW, kwelinye icala, yenziwa ngokugoba iikhoyili ecaleni kweasi esembindini ukuze idityaniswe ngobude bayo bonke.
Ngokuqhelekileyo, imibhobho engenamthungo isetyenziselwa izicelo zoxinzelelo oluphezulu, ngelixa iipayipi ze-ERW zisetyenziselwa inkonzo kwiindawo eziphantsi kunye neziphakathi zoxinzelelo.
Ukongezelela, ngenxa yeempawu ezikhuselekileyo zokhuseleko lwemibhobho engenamthungo, isetyenziswa ngokubanzi kwioli kunye negesi, ukucocwa kweoli kunye namanye amashishini amachiza, kwaye umgaqo-nkqubo wokungavuzi uyafuneka ukuze kuqinisekiswe ukhuseleko lwabantu kunye namashishini.Kwangaxeshanye, imibhobho ye-ERW eyenziwe kakuhle phantsi kolawulo olungqongqo lwekhwalithi ingasetyenziselwa iinkonzo ezifanayo ngaphandle kweenkonzo eziqhelekileyo ezifana nokuthuthwa kwamanzi, i-scaffolding kunye nocingo.
Kuyaziwa ukuba ukugqitywa kwangaphakathi kweepayipi ze-ERW zihlala zilawulwa ngeendlela zokulawula umgangatho olungileyo, ngoko zihlala zingcono kunemibhobho engenamthungo.
Kwimeko ye-ASTM A53, uhlobo lwe-S luthetha ukuba alunamthungo.Uhlobo F - isithando somlilo, kodwa i-welding, uhlobo lwe-E - ukumelana ne-welding.Kuko konke.Le yeyona ndlela ilula yokufumanisa ukuba umbhobho awunomthungo okanye i-ERW.
Ingcebiso: I-ASTM A53 iBanga B lidume kakhulu kunamanye amabanga.Le mibhobho inokuba bhetyebhetye ngaphandle kokwalekwa, okanye ingafakwa igalvanized okanye idiphu eshushu ifakwe igalvanized kwaye yenziwe kusetyenziswa inkqubo yokuvelisa edityanisiweyo okanye engenamthungo.Kwicandelo le-oyile kunye negesi, iipayipi ze-A53 zisetyenziselwa ukusetyenziswa kwezakhiwo kunye nezingabalulekanga.
