Umbhobho weCarbon Steel Welded
Umbhobho odityaniswe ngeempundu wenziwa ngokondla ipleyiti yentsimbi eshushu ngokusebenzisa imilo eya kuthi iqengqeleke ibe yimilo engqukuva engqukuva.Ukucinezela ngenkani iziphelo zombini zeplate kunye kuya kuvelisa idibaniso edibeneyo okanye i-seam.Umzobo 2.2 ubonisa ipleyiti yentsimbi njengoko iqala inkqubo yokwenza umbhobho we-butt-welded
Eyona ndlela ixhaphakileyo kwezi zintathu ngumbhobho we-spiral-welding.Umbhobho we-Spiral-welded wenziwa ngokujijwa kwemicu yentsimbi ibe yimilo engqukuva, efana nomchebi weenwele's ipali, emva koko ukuwelda apho imiphetho idibana khona ukwenza i-seam.Olu hlobo lombhobho lukhawulelwe kwiinkqubo zombhobho usebenzisa uxinzelelo oluphantsi ngenxa yeendonga zayo ezincinci.Umzobo 2.3 ubonisa umbhobho we-spiral-welding njengoko ubonakala phambi kwe-welding.
Nganye kwiindlela ezintathu zokuvelisa umbhobho ineenzuzo zayo kunye nokungonakali.Umbhobho we-butt-welded, umzekelo, wenziwa kwipleyiti eqengqelekayo enobunzima obufanayo bodonga kwaye inokuhlolwa iziphene phambi kokwakhiwa kunye nokuwelda.Le ndlela yokuvelisa iluncedo ngakumbi xa iindonga ezincinci kunye nobude obude bufunekayo.Ngenxa yothungo oludityanisiweyo, nangona kunjalo, kukho iziphene ezinokuthi zibaleke kwiitshekhi ezininzi zokulawula umgangatho ezenziwa ngexesha lenkqubo yokuvelisa.
Ngenxa yoko, i-American National Standards Institute (ANSI) yavelisa izikhokelo eziqinileyo zokwenziwa kombhobho.Uxinzelelo lweMibhobho yeKhowudi B31 yabhalelwa ukulawula ukwenziwa kombhobho.Ngokukodwa, ikhowudi ye-B31.1.0 inika amandla angama-85% kumbhobho oqengqelekayo, i-60% yepayipi ye-spiral-welded, kunye ne-100% yokuphumelela kwipayipi engenamthungo.
Ngokuqhelekileyo, ubuninzi beendonga ezibanzi ziveliswa ngendlela engenamthungo.Nangona kunjalo, kwiinkqubo ezininzi eziphantsi zoxinzelelo lombhobho, indlela eqhubekayo ye-welded iyona nto iqoqosho kakhulu.Umbhobho ongenamthungo uveliswa ngobude obubodwa kunye nobuphindwe kabini.Ubude obubodwa obungakhethiyo buyohluka ukusuka kwi-16"-0″ukuya ku20"-0″.Imibhobho 2″kwaye ngezantsi zifumaneka kubude obuphindwe kabini obungenamkhethe ukusuka kuma-35"-0″ukuya ku40"-0″.
