ASTM A694 ndi kalasi yachitsulo yaku America
ASTM A694 Forgings for Carbon ndi Aloyi Steel Pipe Flanges, Zopangira, Mavavu ndi Zigawo Zazida Zakuthamanga Kwambiri
A694 ili ndi F42 F46 F48 F50 F52 F56 F60 F65F70
A694 ndi kalasi yachitsulo ku United States, ndipo mankhwala ake ali pafupi ndi a Q345D ku China.Q345D imayenera kutsata njira zochizira kutentha kwambiri isanafike pamakina a A694 F60.

Komanso, ASTM A694 Gr.F60 ndi otsika aloyi zitsulo zakuthupi ntchito zovekera chitoliro pansi pa kuthamanga kwambiri ndi kutentha kwambiri, choncho amatchedwanso A694 F60 zovekera mkulu.
Izi nthawi zambiri zimagwiritsidwa ntchito polumikizana ndi mapaipi amphamvu kwambiri m'mafakitale amafuta, gasi ndi mankhwala, ndipo zimakhala ndi mphamvu zolimba komanso kukana dzimbiri.

Koma kuuma osiyanasiyanaASTM A694 Gr.F60,palibe kufunikira kwa kuuma kwenikweni.The kuuma zimadalira yeniyeni kutentha mankhwala zinthu ndi zinthu udindo.Nthawi zambiri, kuuma kwa zinthu za A694 F60 kumayesedwa pansi pa Brinell hardness (HB) kapena Rockwell hardness (HRC).Mtengo wa kuuma udzasiyana malinga ndi momwe zimapangidwira, kutentha kwa kutentha komanso kupanga zinthuzo.

Tengani matako weld flange ya A694 F60 monga chitsanzo kufotokoza:

A694 F60matako kuwotcherera flangesikophweka kupunduka, ili ndi chisindikizo chabwino ndipo imagwiritsidwa ntchito kwambiri.Imagwiritsidwa ntchito pamapaipi okhala ndi kuthamanga kwakukulu kapena kusinthasintha kwa kutentha kapena kutentha kwambiri, kuthamanga kwambiri komanso mapaipi otsika.Amagwiritsidwa ntchito polumikiza mapaipi ndi mavavu okhala ndi PN wamkulu kuposa 2.5MPa;Amagwiritsidwanso ntchito m'mapaipi otumizira zinthu zodula, zoyaka moto komanso zophulika.Ili ndi moyo wautali wautumiki.Malinga ndi mayeso a dzimbiri m'munda, moyo wake wautumiki ukhoza kufika zaka 100 ndipo sufunikira kukonzedwa.Chifukwa chake, chiŵerengero cha ntchito ndi mtengo wake ndi wabwino kwambiri, mtengo wake wogwiritsira ntchito ndi wotsika, ndipo phindu lake lachuma ndilofunika kwambiri.

A694 F60 butt kuwotcherera flange imadziwika ndi kugwirizana odalirika ndi otetezeka, yomanga yabwino ndi yachangu, ukhondo wabwino ndi chitetezo chilengedwe ntchito, ang'onoang'ono otaya kuthamanga kuthamanga, ngakhale amphamvu dongosolo unsembe, zonse lotseguka ndi zobisika unsembe, palibe kukonzanso ndi kukonza, wapamwamba ntchito zachuma, ndi osiyanasiyana ntchito.Imagwiritsidwa ntchito pakufalitsa kwamadzimadzi otsika kwambiri monga madzi ozizira ndi otentha, madzi akumwa mwachindunji, kutenthetsa, zoziziritsa kukhosi, chitetezo chamoto, gasi, ndi zina zambiri, komanso mankhwala, chakumwa, chakudya Kupatsirana kwamadzi otsika m'makampani opanga mankhwala ndi mafakitale ena.
