Likoahelo tsa flange, tse tsejoang hape e le lipoleiti tse foufetseng kapa li-blind flange, li bapala karolo ea bohlokoa tsamaisong ea maemo a naha ea flange. Lipoleiti tsena tse tiileng, tse kang likoahelo tsa tšepe, ke likarolo tsa bohlokoa tse sebelisetsoang ho thibela ho buleha ha liphaephe le ho thibela ho phalla ha lintho. Ho feta moo, li-flange tse foufetseng li fumana lits'ebetso maemong a fapaneng, joalo ka liphaephe tsa lekala tsa phepelo ea metsi le likarolo tsa nakoana nakong ea tlhahlobo ea khatello. Tataisong ena e batsi, re tla batlisisa ka litekanyetso tsa tlhahiso ea li-blind flanges, re hlahlobe litekanyetso tse tsebahalang joalo ka ANSI, DIN, JIS, BS, le tse ling. Ho feta moo, re tla fana ka leseli holim'a limaraka tsa tšepe tse sebelisoang ho etsa li-blind flange, ho netefatsa kutloisiso ea hau ea karolo ena ea bohlokoa.
Serapa sa 1: Ho Utloisisa Likoahelo tsa Flange le Mesebetsi ea Tsona
Likoahelo tsa flange, tse tsejoang ka hore ke lipoleiti tse foufetseng kapa li-flange tse foufetseng, ke likarolo tsa bohlokoa tsa tsamaiso ea liphaephe. Sepheo sa bona ke ho thibela menyetla ea liphaephe ka katleho le ho thibela likahare hore li se ke tsa phalla. E entsoe ka thepa e tiileng, likoahelo tsa flange li pota-potiloe ke masoba a bolt bakeng sa sehokelo se sireletsehileng. Li tšoana le likhurumetso tse tiileng tsa tšepe, li ka fumanoa ka meralo e fapaneng, e kang e bataletseng, e phahamisitsoeng, e khohomoha le e khohomoha, le holim'a leleme le groove. Ho fapana le li-flange tsa welding, li-flange tse foufetseng ha li na molala. Likaroloana tsena hangata li sebelisoa qetellong ea lipeipi tsa lekala la phepelo ea metsi, ho netefatsa hore ha ho na ho lutla ho neng ho sa lebelloa kapa tšitiso.
Serapa sa 2: Ho Hlahloba Mekhoa ea Tlhahiso ea Blind Flange
Li-flange tse foufetseng li khomarela litekanyetso tse khethehileng tsa tlhahiso ho netefatsa boleng, ho lumellana, le ho lumellana. Maemo a tsebahalang indastering a kenyelletsa ANSI B16.5, DIN2576, JISB2220, KS B1503, BS4504, UNI6091-6099, ISO7005-1:1992, HG20601-1997, HG20622-391-1991-1991 GB 23.4- 2000, JB/T86.1~86.2-1994. Tekanyetso e 'ngoe le e' ngoe e hlahisa likarolo tse fapaneng tsa li-flange tse foufetseng, tse kang boholo, litlhoko tsa thepa, litekanyetso tsa khatello le mekhoa ea tlhahlobo. Ho bohlokoa ho shebana le maemo a ikhethileng a amanang le projeke ea hau ho netefatsa ts'ebetso e nepahetseng ea foufo ea flange le ho lumellana le sistimi ea hau ea liphaephe.
Serapa sa 3: Ho Bula Mephato ea Tšepe e Sebelisitsoeng ho Blind Flange Manufacturing
Khetho ea limaraka tsa tšepe e phetha karolo ea bohlokoa tlhahisong ea li-flange tse foufetseng, kaha li ama ka ho toba ho tšoarella ha tsona, matla le ho hanyetsa ho bola. Likarolo tse fapaneng tsa tšepe li sebelisoa indastering ea li-blind flange, ho kenyelletsa empa e sa felle ho:
1. Carbon Steel: Khetho e theko e tlaase e nang le matla a babatsehang le ho hanyetsa mocheso o phahameng. Limaraka tse tloaelehileng tsa carbon steel tse sebelisoang ke ASTM A105, ASTM A350 LF2, le ASTM A516 Gr. 70.
2. Stainless Steel: E loketse lits'ebetso moo ho hanyetsanang le kutu ho leng bohlokoa. Limaraka tse tummeng tsa tšepe e sa hloekang li kenyelletsa ASTM A182 F304/F304L, ASTM A182 F316/F316L, le ASTM A182 F321.
3. Alloy Steel: Likarolo tsena tsa tšepe li ntlafatsa khanyetso ea foufo ea flange khahlanong le khatello e itseng, joalo ka mocheso o phahameng kapa tikoloho e senyang. Mefuta e tloaelehileng ea tšepe ea alloy e sebelisoang ke ASTM A182 F5, ASTM A182 F9, le ASTM A182 F91.
Ho bohlokoa ho khetha boemo bo nepahetseng ba tšepe ho ipapisitse le litlhoko tse ikhethileng tsa projeke ea hau, u nahanne ka lintlha tse kang tikoloho eo u sebetsang ho eona, khatello, mocheso le ho pepeseha ha lik'hemik'hale.
Serapa sa 4: Ho netefatsa hore ho na le lifofu tsa boleng bo holimo le tse lumellanang
Ha u reka li-flange tse foufetseng, ho bohlokoa ho netefatsa hore li lumellana le maemo a nepahetseng a tlhahiso le litifikeiti tsa boleng. Batla bafani ba thepa ba tšepahalang ba khomarelang mekhoa e thata ea tlhahiso, ho netefatsa hore liphahlo tsa bona tse foufetseng li finyella kapa li feta litlhoko tsa indasteri. Ho feta moo, nahana ka barekisi ba fanang ka litifikeiti tsa tlhahlobo ea thepa (MTC) bakeng sa taolo e thata ea boleng. Litokomane tsena li tiisa hore li-flange tse foufetseng li fetile tlhahlobo e hlokahalang, li tiisa hore li loketse morero oa hau.
Serapa sa 5: Qetello le Likhothaletso tsa ho Qetela
Li-flange tse foufetseng, tse tsejoang hape e le likoahelo tsa flange kapa lipoleiti tse foufetseng, ke likarolo tsa bohlokoa tsa tsamaiso ea liphaephe. Tlhahiso ea bona e khomarela litekanyetso tse khethehileng ho netefatsa ho lumellana le ho lumellana. Maemo a tsebahalang a tlhahiso joalo ka ANSI B16.5, DIN, JIS, le BS a laola boholo ba foufo ea flange, litlhoko tsa thepa, le litekanyetso tsa khatello. Ho feta moo, limaraka tsa tšepe tse kang tšepe ea carbon, tšepe e sa hloekang, le tšepe ea alloy li khethoa ka hloko ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele. Ha u reka li-flange tse foufetseng, kamehla khetha barekisi ba hlomphehang ba etelletsang boleng pele le ho fana ka litifikeiti tse hlokahalang. Ka ho utloisisa litekanyetso tsa tlhahiso ea li-blind flanges le limaraka tsa tšepe, u ka khetha ka boits'epo likarolo tse nepahetseng bakeng sa lipeipi tsa hau, ho netefatsa ts'ebetso e ntle le e bolokehileng.
