I-ASTM A694 libakala lentsimbi laseMelika
I-ASTM A694 Forgings ye-Carbon kunye ne-alloy Steel Pipe Flanges, iziFakelo, iiValuvu kunye nezahlulo zeSixhobo sokuThumela ngoxinzelelo oluPhezulu
I-A694 ine-F42 F46 F48 F50 F52 F56 F60 F65 iyonke.F70
I-A694 ibakala lensimbi e-United States, kwaye ukubunjwa kwayo kweekhemikhali kusondele kwi-Q345D e-China. I-Q345D idinga ukujongana neenkqubo ezingqongqo zonyango lobushushu ngaphambi kokufikelela kwiipropati zemishini ye-A694 F60.

Ukongeza, i-ASTM A694 Gr.F60 ikwayinto ephantsi yentsimbi esetyenziselwa ukufakwa kombhobho phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu, ngoko ikwabizwa ngokuba yi-A694 F60 yokufakelwa koxinzelelo oluphezulu.
Esi sixhobo siqhele ukusetyenziselwa ukudityaniswa kwemibhobho yoxinzelelo oluphezulu kwi-oyile, igesi yendalo kunye namashishini ekhemikhali, kwaye inamandla aphezulu okuqina kunye nokumelana nokugqwala.

Ngokubhekiselele kuluhlu lobunzimaI-ASTM A694 Gr.F60,akukho mfuneko yokuqina. Ubunzima buxhomekeke kwiimeko ezithile zonyango lobushushu kunye nesimo sezinto eziphathekayo. Ngokubanzi, uluhlu lobunzima bezinto ze-A694 F60 zivavanywa phantsi kobunzima beBrinell (HB) okanye ukuqina kwe-Rockwell (HRC). Ixabiso lobunzima liya kuhluka ngokwemichiza, iimeko zokunyanga ukushisa kunye nenkqubo yokuvelisa izinto.

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

A694 F60butt welding flangeakukho lula ukonakala, inotywino olulungileyo kwaye isetyenziswa kakhulu. Isebenza kwimibhobho enoxinzelelo olukhulu okanye ukuguquka kweqondo lokushisa okanye ukushisa okuphezulu, uxinzelelo oluphezulu kunye nemibhobho yokushisa ephantsi. Ngokuqhelekileyo isetyenziselwa ukudibanisa imibhobho kunye neevalvu ezine-PN enkulu kune-2.5MPa; Ikwasetyenziswa kwimibhobho ehambisa imidiya ebiza imali eninzi, enokutsha kunye neziqhushumbisi. Inobomi benkonzo ende. Ngokutsho kwedatha yovavanyo lwe-corrosion field, ubomi bayo benkonzo bunokufikelela kwiminyaka eyi-100 kwaye ayifuni ukugcinwa. Ngoko ke, umlinganiselo wayo wexabiso lentsebenzo ulungile kakhulu, iindleko zayo zokusebenza ziphantsi, kwaye iinzuzo zayo kwezoqoqosho zibalulekile.

I-A694 F60 i-flange ye-welding ye-butt ibonakaliswe ngoqhagamshelwano oluthembekileyo nolukhuselekileyo, ulwakhiwo olufanelekileyo nolukhawulezayo, ucoceko oluhle kunye nokusebenza kokusingqongileyo, ilahleko encinci yoxinzelelo, ukuhambelana kwenkqubo eyomeleleyo, zombini ukufakwa okuvulekileyo nokufihliweyo, akukho kuhlaziywa kunye nokugcinwa, ukusebenza koqoqosho oluphezulu, kunye uluhlu olubanzi lwesicelo. Isebenza kuthungelwano loxinzelelo oluphantsi loluntu olufana namanzi abandayo kunye namanzi ashushu, amanzi okusela ngokuthe ngqo, ukufudumeza, umoya, ukhuseleko lomlilo, igesi, njl., kunye neyeza, isiselo, ukutya Ukuhanjiswa koxinzelelo oluphantsi kushishino lweekhemikhali kunye amanye amashishini.
