Pipe ea boiler
Li-tubes tsa boiler ke e 'ngoe ea lipeipi tse se nang moeli.Mekhoa ea tlhahiso e tšoana le tube e se nang seam, empa e na le litlhoko tse thata bakeng sa ho etsa lipeipi tsa tšepe.Ho ea ka boemo ba mocheso, tube ea boiler e arotsoe ka li-tubes tsa boiler tse akaretsang le li-tube tsa boiler tsa khatello e phahameng.
Mekhoa ea tlhahiso:
① mocheso o akaretsang oa boiler o ka tlase ho 450 ℃, o sebelisa phala e kentsoeng ka ho chesa kapa phala e hulang e batang e etsang phala ea tšepe.
② tube e nang le khatello e phahameng ea khatello e sebelisoa hangata maemong a mocheso o phahameng le phala e phahameng ea khatello, phello ea mocheso o phahameng oa khase le mouoane oa metsi, oxidation le corrosion.Pipe ea tšepe e nang le matla a phahameng a ho phunyeha, ho hanyetsa ho hoholo ha oksijene le ho ba le botsitso bo botle ba mokhatlo.
Sepheo sa li-boiler tubes:
① Li-tubes tsa boiler tse akaretsang li sebelisoa haholo ho etsa li-tubes tsa lebota la metsi, li-tubes ka metsing a belang le liphaephe tsa mouoane o futhumetseng haholo, li-boiler tsa mouoane tse futhumetseng haholo, lipeipi tse kholo le tse nyane tsa mosi le setene sa arch.
② li-tubes tse nang le khatello e phahameng haholo li sebelisetsoa ho etsa li-tubes tse futhumatsang tse phahameng haholo, li-tubes tse futhumatsang moea, phala e kholo ea mouoane.
Sehlopha:
Li-tubes tsa boiler tse akaretsang le li-tube boiler tsa khatello e phahameng li pepesehile ts'ebetsong ea mocheso o phahameng.Li-tubes tsa boiler ka kakaretso, kapa li-tubes tsa boiler tse nang le khatello e phahameng ho latela ts'ebeliso ea tsona li ka aroloa ka liphaephe tse fapaneng tsa tšepe.
