Mocheso ke sesebelisoa sa ho fetisa mocheso se sebelisetsoang ho fetisa matla a ka hare a mocheso pakeng tsa maro a mabeli kapa ho feta a fumanehang ka mocheso o fapaneng.Tubing kapa tube ke karolo ea bohlokoa ea mochine o ntšang mocheso, oo maro a phallang ka oona.Kaha lisebelisoa tse futhumatsang mocheso li ka sebelisoa ho sebetsa, matla, peterole, lipalangoang, moea o futhumatsang moea, sehatsetsi, cryogenic, ho khutlisa mocheso, libeso tse ling le liindasteri tse ling, li-tubes tse futhumatsang mocheso le tsona li ka aroloa ho latela li-tubes tsa li-radiator, li-regenerator, condensers, li-superheaters. , li-preheaters, li- cooler, li-evaporator, le li-boilers.Li-tubes tse futhumatsang mocheso li ka fanoa ka mofuta o otlolohileng, mofuta oa U-bent, mofuta o kobehileng, kapa mokhoa oa noha.Ka kakaretso, ke li-tubes tse se nang moroallo kapa tse cheselitsoeng tse fumanehang ka har'a li-diameter tse ka ntle pakeng tsa 12.7 mm le 60.3 mm tse nang le lebota le batlang le le tšesaane.Hangata li-tubes li kopantsoe le tubesheet ka mokhoa oa ho roala kapa oa ho cheselletsa.Maemong a mang, li-tubing tsa capillary kapa li-diameter tse kholo li sebetsa.Thepa e ka 'na ea e-na le li-fins (finned tube) tse fanang ka bokhoni bo matla ba ho fetisa mocheso.
1. Khetho ea lintho tse bonahalang bakeng sa Heat Exchanger Tubing
Ts'ebetsong ea boenjiniere, khetho ea lisebelisoa bakeng sa li-tubing tsa mocheso o tla etsoa ka thata.Ka kakaretso, tubing e tla ipapisa le lintlha tse fanoeng ho ASME Boiler le Pressure Vessel Code Karolo ea II.Khetho ea thepa e tla ipapisa le ho nahanela ka kakaretso le lipalo tsa khatello ea ho sebetsa, mocheso, sekhahla sa phallo, kutu, khoholeho ea mobu, ho sebetsa hantle, katleho ea litšenyehelo, viscosity, moralo le libaka tse ling.Hangata, li-tubing tsa mocheso li ka fanoa ka lisebelisoa tsa tšepe tse nang le ferrous kapa nonferrous, tse ka hlalosoang hape e le carbon steel, low alloy steel, stainless steel, duplex stainless steel, nickel alloy, alloy ea titanium, alloy ea koporo, alloy ea aluminium, tantalum le zirconium, joalo-joalo.
Litlhaloso tse tloaelehileng tsa lisebelisoa li kenyelletsa: ASTM A178, A179, A209, A210, A213, A214, A249, A250, A268, A334, A423, A450, A789, A790, A803, A1016;ASTM B75, B111, B135, B161, B165, B167, B210, B221, B234, B251, B315, B338, B359, B395, B407, B423, B444, B466, B455, B3 B3 B3 622 .B626, B668, B674, B676, B677, B690, B704, B729, B751 le B829.Sebopeho sa lik'hemik'hale, thepa ea mechine le phekolo ea mocheso li tla lumellana le litekanyetso tse boletsoeng ka holimo ka ho latellana.Li-tubing tse futhumatsang mocheso li ka hlahisoa ka mokhoa o chesang kapa o batang.Ho feta moo, ts'ebetso e chesang ea ho sebetsa e hlahisa filimi e tšesaane le e mahoashe e ntšo ea magnetic iron oxide holim'a eona.Filimi ea mofuta ona hangata e bitsoa "mill scale" e tla tlosoa ka mor'a moo ka ho fetola, ho bentša kapa ho khetha.
2. Teko le Tlhahlobo
