Ke lintho life tse ling tse atileng haholo tseo motho ea tlamang lipeipi a ka li sebelisang ha a cheselletsa?Butt welded fittings, ehlile.Empa na u kile ua ipotsa hore na ke hobane'ng ha hangata ho le bonolo ho fumana lisebelisoa tse sebetsang?
Ha ho tluoa tabeng ea lisebelisoa tse entsoeng ka fektheri tsa butt, ho na le litekanyetso tse khethehileng tse lokelang ho finyelloa nakong ea tlhahiso.Tse tsebahalang haholo ke ANSI le ASME.Ha re shebeng tekanyetso ea ASME B 16.9 le hore na e fapana joang le maemo a ANSI.
ASME B 16.9:Fektheri-E entsoeLisebelisoa tsa Welding Butt
ASME B 16.9 e behiloe ke American Society of Mechanical Engineers.B 16.9 e bua ka lisebelisoa tsa ho tjheseletsa butt tsa feme.ASME B 16.9 e laola boholo, likhatello tsa khatello, boholo, ho tšoaea, thepa, litekanyo tse loketseng, li-contours tsa bokaholimo, tokisetso ea ho qetela, liteko tsa bopaki ba moralo, liteko tsa tlhahiso, le mamello.Boemo bona bo netefatsa hore lisebelisoa li hlahisoa ka mokhoa oo li lokelang ho ba ka ona le litlhaloso, ho nolofalletsa ho kopanya likarolo tse ncha likarolong tse teng, le ho netefatsa polokeho, matla le botsitso.
Ho cheselletsa butt e ka ba mokhoa o ikemetseng kapa oa letsoho, o sebelisetsoang ho kopanya likotoana tsa tšepe.Lisebelisoa tsa ho cheselletsa butle tse betliloeng hangata li bonolo;li entsoe e le hore li ka cheselletsoa ka ho toba holim'a ntho e 'ngoe e loketseng.Leha ho le joalo, ho nahanoa ka seo, li hloka ho ntlafatsoa ho ea ho litekanyetso tse itseng, e le hore li ka lumellana ka nepo le lisebelisoa tse ling.Mefuta ea li-butt weld fitting e ka kenyelletsamatsoele, likhepisi, tee, ba fokotsang, le libaka.
Hobane buttwelding ke e 'ngoe ea mekhoa e atileng haholo ea ho cheselletsa le mekhoa ea ho kopanya, baenjiniere ba mechini ba kanna ba sebelisa le ho sebetsa ka lisebelisoa tse entsoeng ke feme hangata khafetsa.Baetsi ba lisebelisoa tsa butt weld ba tla hloka ho ameha ka litekanyetso le litlhaloso.
Litekanyetso tsa ANSI vs ASME
Litekanyetso tsa ANSI vs ASME bakeng sa likarolo tse ling tse entsoeng ke lifeme li ka fapana.Kahoo, lienjineri li kanna tsa batla ho tseba hore na li sebetsa ho latela maemo a ANSI kapa ASME, kaha maemo a ASME hangata a hlakile haholoanyane mme maemo a ANSI a ka akaretsa.ASME ke tekanyetso e 'nileng ea hlalosa pipefitting ho tloha mathoasong a lilemo tsa bo-1920.Bakeng sa lits'ebetso tse ngata, ho latela maemo a ASME le hona ho tla latela litekanyetso tsa ANSI.
ANSI e thehiloe ke American National Standards Institute.ANSI e laola mefuta e mengata haholo ea liindasteri, athe ASME e etselitsoe li-boilers, likepe tsa khatello le libaka tse ling tse tšoanang.Kahoo, le hoja ntho e 'ngoe e ka finyella litekanyetso tsa ANSI, e ka' na ea se ke ea finyella litekanyetso tsa ASME;Litekanyetso tsa ASME li ka ba tse tobileng kapa tse thata haholo.Ha ho tluoa ho maemo a B16.9, leha ho le joalo, maemo a ANSI le ASME a kanna a tšoana.
Melao le melaoana e lula e le ea bohlokoa, haholo-holo nthong e kang khatello e phahameng joaloka pipefittings le boilers.Hobane litekanyetso le tsona li ka fetoha, ho bohlokoa hore mekhatlo e fane ka nako e itseng ho inchafatsa ka liphetoho le litlatsetso.Ho Steel Forgings, re lula re sebetsa ho netefatsa hore likotoana tsa rona li fihlela litekanyetso tsohle tse hlokahalang - le hore li fetela holimo le ho feta ho latela boleng le botsitso.
