I-ASTM A694 iyibanga lensimbi laseMelika
I-ASTM A694 Forgings ye-Carbon kanye ne-alloy Steel Pipe Flanges, Ukufakwa, Amavalvu Nezingxenye Zesisetshenziswa Sokudlulisa Ukucindezela Okuphezulu
I-A694 inesamba esingu-F42 F46 F48 F50 F52 F56 F60 F65F70
I-A694 iyizinga lensimbi e-United States, futhi ukwakheka kwayo kwamakhemikhali kuseduze naleyo ye-Q345D e-China.I-Q345D idinga ukwenza izinqubo eziqinile zokwelashwa kokushisa ngaphambi kokufinyelela izakhiwo zemishini ze-A694 F60.

Ngaphezu kwalokho, i-ASTM A694 Gr.F60 nayo iyinsimbi ephansi ye-alloy esetshenziselwa ukufakwa kwamapayipi ngaphansi kwengcindezi ephezulu kanye nokushisa okuphezulu, ngakho-ke ibizwa nangokuthi i-A694 F60 ukufakwa kwengcindezi ephezulu.
Le nto ivamise ukusetshenziselwa ukuxhunywa kwamapayipi anengcindezi ephezulu ezimbonini zikawoyela, igesi yemvelo namakhemikhali, futhi inamandla aqine kakhulu nokugqwala.

Ngokuqondene nobulukhuni ububanziI-ASTM A694 Gr.F60,asikho isidingo esiqondile sokuqina.Ukuqina kuncike ezimweni ezithile zokwelashwa kokushisa kanye nesimo sezinto ezibonakalayo.Ngokuvamile, ububanzi bokuqina bezinto ezisetshenziswayo ze-A694 F60 buhlolwa ngaphansi kokuqina kwe-Brinell (HB) noma ukuqina kwe-Rockwell (HRC).Inani lobulukhuni lizohluka ngokuya ngamakhemikhali, izimo zokwelashwa kokushisa kanye nenqubo yokukhiqiza impahla.

Thatha i-butt weld flange ye-A694 F60 njengesibonelo ukuchaza:

A694 F60i-butt welding flangeakulula ukukonakalisa, inokuvalwa kahle futhi isetshenziswa kabanzi.Isebenza kumapayipi anokucindezela okukhulu noma ukushintshashintsha kwezinga lokushisa noma izinga lokushisa eliphezulu, umfutho ophezulu kanye namapayipi okushisa aphansi.Ngokuvamile isetshenziselwa ukuxhuma amapayipi namavalvu ane-PN enkulu kuno-2.5MPa;Ibuye isetshenziswe kumapayipi adlulisa imidiya ebizayo, evuthayo kanye neziqhumane.Inempilo ende yesevisi.Ngokusho kwedatha yokuhlola ukugqwala kwensimu, impilo yayo yesevisi ingafinyelela iminyaka eyi-100 futhi ayidingi ukunakekelwa.Ngakho-ke, isilinganiso sayo sokusebenza nenani sihle kakhulu, izindleko zayo zokuphila ziphansi, futhi izinzuzo zayo zezomnotho zibalulekile.

I-A694 F60 butt welding flange ibonakala ngokuxhumeka okuthembekile nokuphephile, ukwakhiwa okulula nokusheshayo, ukuhlanzeka okuhle nokusebenza kokuvikelwa kwemvelo, ukulahlekelwa kwengcindezi encane yokugeleza, ukuhambisana okuqinile kwesistimu, kokubili ukufakwa okuvulekile nokufihliwe, akukho ukuvuselelwa nokugcinwa, ukusebenza komnotho okuphakeme, kanye ububanzi bohlelo lokusebenza.Isebenza ekudluliseleni uketshezi olunomfutho wegazi ophansi njengamanzi abandayo nashisayo, amanzi okuphuza aqondile, ukufudumeza, ukomisa umoya, ukuvikela umlilo, igesi, njll., kanye nomuthi, isiphuzo, ukudla Ukudluliselwa koketshezi olunomfutho ophansi embonini yamakhemikhali kanye ezinye izimboni.
