4. Dade ni akɛwo mli
Akɛ dade ni akɛwoɔ mli lɛ tsuɔ nii kɛhaashinaa lɛ naa valve, globe valve, plɔg valve, kɛ ekrokomɛi kɛha hulutsoo t≤100°C, gbɛi ni ji PN≤1.6MPa, gas kɛ mu.
5. Babbitt dade ni akɛfee nii
Akɛ Babbitt aloi tsuɔ nii kɛhaa ammonia shikpɔŋ nɔ valve ni hulutsoo t-70 ~ 150 ° C kɛ gbɛi nɔ hewalɛ PN≤ 2.5 MPa.
6. Akɔɔble ni akɛfee ekome
Nibii ni afɔɔ feemɔ kɛfeɔ akɔɔble nibii ji 6-6-3 tin akɔɔble kɛ 58-2-2 manganese akɔɔble. Akɔɔble aloi lɛ yɛ hewalɛ ni hi ni ekɛteɔ shi ewoɔ nibii ni fiteɔ lɛ, ni ehi kɛha nu kɛ lasu ni mli edɔ t≤200°C kɛ nominal pressure PN≤1.6MPa. Bei pii lɛ akɛtsuɔ nii yɛ...shinaa lɛ naa valvɛi, glob valvɛi,kwɛmɔ valvɛi lɛ, plɔg valvɛi, kɛ ekrokomɛi.
7. Chrome dade ni bɛ ŋmɔlɔ
Chromium dade ni akɛtsuɔ nii ni afɔɔ nitsumɔ ji 2Cr13 kɛ 3Cr13, ni agbe amɛ ni afee amɛ la, ni amɛhe wa jogbaŋŋ ni nyɛɔ amɛshiɔ ŋmeii. Bei pii lɛ, akɛtsuɔ nii yɛ valves kɛha adafitswaa tamɔ nu, lasu kɛ mu ni mli edɔ t≤450°C kɛ nominal pressure PN≤32MPa.
8. Kromium-nikel-titanium dade ni bɛ ŋmɔlɔ
1Cr18Ni9ti, ni yɔɔ dade ni sɛɛ tsɛɔ ni ji chromium-nickel-titanium ni akɛtsuɔ nii babaoo lɛ ji dade ni hi jogbaŋŋ ni nyɛɔ eshiɔ ŋmeii, ŋmeii ni efiteɔ kɛ dɔlɛ ni nyɛɔ eshiɔ. Ehi jogbaŋŋ kɛha hulutsoo, nitric acid kɛ adafitswaa woji krokomɛi ni hulutsoo t≤600°C kɛ nɔnyɛɛ ni ji PN≤6.4MPa, ni akɛtsuɔ nii kɛhaa globe valve, bɔɔlu valve, kɛ ekrokomɛi.
9. Dade ni akɛ nitrid ewo mli
Nitrided dade ni afɔɔ nitsumɔ ji 38CrMoAlA, ni yɔɔ ŋmei ni hi jogbaŋŋ kɛ ŋmei ni nyɛɔ eshiɔ ŋmei yɛ carburizing helatsamɔ sɛɛ. Akɛ nitsumɔ ni afɔɔ nitsumɔ yɛ tsɔne ni haa hulutsoo lɛ shinaa naa lɛ mli ni hulutsoo t≤540°C kɛ nɔnyɛɛ ni ji PN≤10MPa.
10. Boronfeemɔ
Boronizing tsuɔ ŋwɛi ŋta lɛ he nii tɛ̃ɛ kɛjɛɔ nibii ni yɔɔ valve gbɔmɔtso lɛ loo disc gbɔmɔtso lɛ mli lɛ mli, ni no sɛɛ lɛ etsuɔ boronizing ŋwɛi ŋta lɛ he nii, ŋta lɛ hiɛ lɛ yɛ nɔ ni hi ni ekɛteɔ shi ewoɔ fitemɔ. Akɛtsuɔ nii yɛ tsɔne ni haa hulu tsoɔ waa lɛ mli.
