Ho tsebisa ka Blind flange

Li-flange tse foufetseng ke karolo ea bohlokoa tsamaisong ea liphaephe, tse atisang ho sebelisoa ho koala masoba a liphaephe kapa likepe bakeng sa tlhokomelo, ho hlahloba kapa ho hloekisa. E le ho netefatsa boleng, polokeho le ho fapanyetsana ha li-flanges tse foufetseng, Mokhatlo oa Machaba oa Boemo (ISO) le mekhatlo e meng ea litekanyetso tse amehang e fane ka letoto la litekanyetso tsa machaba tse koahelang likarolo tsohle tsa moralo, tlhahiso le tšebeliso ea lifofu tse foufetseng.

Mona ke tse ling tsa litekanyetso tsa mantlha tsa machaba tse amanang le li-blind flanges le litaba tsa tsona:

ASME B16.5

- Liphahlo tsa liphaephe - Karolo ea 1: Lipene tsa tšepe bakeng sa liphaephe tsa indasteri le litšebeletso tse akaretsang: Tekanyetso ena e akaretsa mefuta e fapaneng ea liphaephe, ho kenyeletsoa le liphaephe tse foufetseng. Tsena li kenyeletsa boholo, mamello, sebopeho sa holim'a khokahanyo le litlhoko tsa thepa ea flange ea foufetseng ea foufetseng.

ASME B16.48

-2018 - Line Blanks: Tekanyetso e phatlalalitsoeng ke American Society of Mechanical Engineers (ASME) e koahelang ka ho khetheha liphahlo tse foufetseng, tseo hangata ho thoeng ke "likheo tsa mela." Tekanyetso ena e totobatsa boholo, lisebelisoa, mamello le litlhoko tsa tlhahlobo bakeng sa li-flange tse foufetseng ho netefatsa ho ts'epahala ha lipeipi tsa indasteri le litšebeletso tse akaretsang.

EN 1092-1

-2018 - Li-flanges le manonyeletso a tsona - Li-flange tse chitja bakeng sa liphaephe, li-valve, li-fittings le lisebelisoa, PN e khethiloeng - Karolo ea 1: Li-flange tsa tšepe: Ena ke litekanyetso tsa Europe tse koahelang moralo, boholo, lisebelisoa le litlhoko tsa ho tšoaea. E loketse tsamaiso ea lipeipi Fora, Jeremane, Italy le linaheng tse ling tsa Europe.

JIS B 2220

-2012 - Liphaephe tsa lipeipi tsa tšepe: Tekanyetso ea Liindasteri ea Japane (JIS) e totobatsa boholo, mamello le litlhoko tsa thepa bakeng sa li-flange tse foufetseng ho finyella litlhoko tsa tsamaiso ea liphaephe tsa Japane.

Tekanyetso ka 'ngoe ea machaba e kenyelletsa tse latelang:

Litekanyo le mamello: Tekanyetso e bolela boholo ba li-flange tse foufetseng le litlhoko tse amanang le mamello ho netefatsa hore ho na le phetoho pakeng tsa li-fofu tse hlahisoang ke bahlahisi ba fapaneng. Sena se thusa ho netefatsa botsitso le ho feto-fetoha ha liphaephe tsa tsamaiso.

Litlhoko tsa lintho tse bonahalang: Tekanyetso e 'ngoe le e' ngoe e totobatsa litekanyetso tsa thepa tse hlokahalang ho etsa li-flange tse foufetseng, hangata tšepe ea carbon, tšepe e sa hloekang, tšepe ea alloy, joalo-joalo. Litlhoko tsena li kenyelletsa lik'hemik'hale tsa thepa, thepa ea mochine le litlhoko tsa phekolo ea mocheso ho etsa bonnete ba hore foufo e na le matla a lekaneng le ho hanyetsa ho bola.

Mokhoa oa tlhahiso: Hangata litekanyetso li kenyelletsa mokhoa oa ho etsa li-flange tse foufetseng, ho kenyelletsa le ho lokisa thepa, ho etsa, ho cheselletsa le ho phekola mocheso. Mekhoa ena ea tlhahiso e netefatsa boleng le ts'ebetso ea li-flange tse foufetseng.

Teko le tlhahlobo: Tekanyetso e 'ngoe le e 'ngoe e boetse e kenyelletsa litlhoko tsa tlhahlobo le tlhahlobo bakeng sa li-flange tse foufetseng ho netefatsa hore li ka sebetsa ka polokeho le ka ts'epo ts'ebelisong ea 'nete. Liteko tsena hangata li kenyelletsa tlhahlobo ea khatello, tlhahlobo ea weld, le tlhahlobo ea ts'ebetso ea thepa.

Litekanyetso tsa machaba li netefatsa botsitso ba lefats'e le ho fapanyetsana ha li-flange tse foufetseng. Ebang ke indastering ea oli le khase, lik'hemik'hale, phepelo ea metsi kapa makaleng a mang a indasteri, litekanyetso tsena li bapala karolo ea bohlokoa ho netefatsa polokeho, ts'epahalo le ts'ebetso ea likhokahano tsa lipeipi. Ka hona, ha u khetha le ho sebelisa li-flange tse foufetseng, ke habohlokoa ho utloisisa le ho lumellana le litekanyetso tse sebetsang tsa machaba ho netefatsa ts'ebetso e tsitsitseng le polokeho ea tsamaiso ea liphaephe.
