Indima yejenereyitha yomphunga "umbhobho ofudumeleyo"
Ukufudumeza umbhobho we-steam ngejenereyitha ye-steam ngexesha lokunikezelwa komphunga kuthiwa "umbhobho ofudumeleyo". Umsebenzi wombhobho wokufudumeza ukufudumeza imibhobho ye-steam, i-valve, i-flanges, njl njl ngokuthe ngcembe, ukwenzela ukuba izinga lokushisa lemibhobho lifikelele ngokuthe ngcembe kwiqondo lokushisa lomphunga, kwaye lilungiselele ukunikezelwa kwe-steam kwangaphambili. Ukuba i-steam ithunyelwa ngokuthe ngqo ngaphandle kokufudumala imibhobho kwangaphambili, iipayipi, i-valve, ii-flanges kunye nezinye izinto ziya konakala ngenxa yoxinzelelo lwe-thermal ngenxa yokunyuka kokushisa okungalinganiyo.
