Na ua tseba ka li-tubes tsa boiler tse se nang seam 20G le SA-210C (25MnG)?

20G ke sehlopha sa tšepe se thathamisitsoeng ho GB/T5310 (limaraka tse tsamaellanang le linaha tse ling: st45.8 Jeremane, STB42 Japane, SA106B United States), 'me ke tšepe e sebelisoang haholo bakeng sa liphaephe tsa tšepe tsa boiler. Sebopeho sa eona sa lik'hemik'hale le thepa ea mochine ha e le hantle li tšoana le tsa lipoleiti tse 20. Tšepe ena e na le mocheso o itseng oa kamore le matla a mocheso o phahameng o mahareng, likhahla tse tlase tsa khabone, polasetiki e ntle le ho tiea, 'me e na le mohatsela o motle o batang le o chesang oa ho theha le ho ts'oara. karolo ea mocheso o tlase, litsebi tsa moruo, le mabota a pholileng ka metsi; Ka mohlala, liphaephe tse nyenyane tsa bophara li sebelisoa e le liphaephe tse futhumatsang holim'a metsi ka mocheso oa lebota oa ≤ 500 ℃, hammoho le liphaephe tsa marako tse pholileng ka metsi le liphaephe tsa economizer. Ka lebaka la graphitization e bakoang ke ts'ebetso ea nako e telele ea carbon steel ka holimo ho 450 ℃, ho molemo ho fokotsa mocheso oa nako e telele oa ho sebetsa oa liphaephe e le libaka tse futhumatsang ho ea ka tlase ho 450 ℃. Tšepe ena e ka finyella litlhoko tsa li-superheaters le liphaephe tsa mouoane sebakeng sena sa mocheso ho ea ka matla, 'me e na le khanyetso e ntle ea oxidation, polasetiki e ntle, thata, ts'ebetso ea ho tjheseletsa le lisebelisoa tse ling tse batang le tse chesang, ho etsa hore e sebelisoe haholo.

SA-210C (25MnG) ke boemo ba tšepe boemong ba ASME SA-210. Ke phala e nyane ea tšepe ea carbon manganese e sebelisoang ho liboilers le li-superheaters, le mofuta oa pearlescent tšepe e matla a phahameng. Ts'ebetso ea tlhahiso ea tšepe ena e bonolo, 'me ts'ebetso ea eona e batang le e chesang e sebetsa hantle. Ho fetola 20G ka eona ho ka fokotsa botenya ba marako a tšesaane, ho fokotsa tšebeliso ea thepa, hape ho ntlafatsa boemo ba ho fetisa mocheso oa li-boilers.

Sebaka sa ts'ebeliso ea eona le mocheso ha e le hantle li tšoana le 20G, haholo-holo e sebelisetsoang mabota a pholileng ka metsi, li-economizers, li-superheaters tse nang le mocheso o tlase le likarolo tse ling tse nang le mocheso o sebetsang o ka tlase ho 500 ℃.

Shandong Kungang Metal Technology Co., Ltd. haholo-holo e hlahisa lihlahisoa tsa phala ea tšepe. 20G le SA-210C ke lisebelisoa tse sebelisoang ka mokhoa o tloaelehileng libakeng tsa polokelo, 'me litlhaloso tse khethehileng li ka hlahisoa ho latela litlhoko tsa bareki. Sehlahisoa se entsoe ka tšepe ea boleng bo phahameng, 'me lipontšo tsohle tsa' mele le tsa lik'hemik'hale li finyella litekanyetso tsa naha. Sehlahisoa sena se tumme ka hare ho naha le linaheng tse ling. Re labalabela lipuisano tsa hau!
