UkuVeliswa ngokuBanzi kunye neNkxaso yoShishino oluninzi
Ityala loMthengi: uMvelisi weValve eDenmark (i-Petrochemical Field)
Imvelaphi yoMthengi: Umenzi wevalve yeshishini e-Zealand, eDenmark, egxile kwiivalvu zebhola zepetrochemical kunye neengcango zesango, kufuneka enze ngokwezifiso i-stainless steel stainless (316L) imizimba yevalve eneenkcukacha ze-DN50-DN200 kunye nemfuno yonyaka yamaqhekeza angama-20,000.
Imingeni engundoqo: I-316L insimbi engenasici idinga ukulawula umxholo wekhabhoni ≤0.03%, ukumelana ne-intergranular corrosion, ukudlula uvavanyo lokutshiza ityuwa (iiyure ze-1,000); i-valve body flow channel kufuneka ihambe kakuhle, kungabikho burrs kunye ne-inclusions, kwaye uvavanyo lokuqina ludibana nomgangatho we-API 6D; umthengi ufuna ukucaciswa kwezinto ezininzi, imveliso exubileyo encinci, kunye nenani elincinci le-odolo lamaqhekeza angama-50 / ukucaciswa.
Isisombululo se-Ruican: 1. Ukulawulwa kwezinto eziphathekayo: Sebenzisa i-high-purity 316L insimbi ye-scrap, i-medium frequency furnace melting, ukukhuselwa kwe-argon, uhlalutyo lwe-spectral ye-intanethi ye-carbon content. 2. Indlela yeNkqubo: Ukwenziwa kotyalo-mali → unyango lwesisombululo (1080℃, ukupholisa amanzi) → Umatshini we-CNC → ukuchola nokupasa → uvavanyo lokuqina. 3. Imveliso eguquguqukayo: Yakha umgca wemveliso jikelele oguquguqukayo, wamkele iteknoloji yokutshintsha ngokukhawuleza i-mold ukuze ufezekise imveliso edibeneyo emininzi, kunye nexesha lokutshintsha i-mold ≤30 imizuzu.
Iziphumo zobungakanani: Akukho rust ebomvu kwi-1,000-iyure yokuvavanya ityuwa yokutshiza, isantya esisodwa esifanelekileyo sovavanyo lwe-tightness 99.8%, ehambelana nomgangatho we-API 6D; umjikelo wokuhanjiswa kwee-odolo ze-batch ezincinci zifutshane ukusuka kwiiveki ezi-4 ukuya kwiiveki ezi-2, kwaye umjikelo omtsha wokuphuhlisa imveliso ufinyezwa ngama-30%; intsebenziswano ithathe iminyaka emi-4, ukwandisa ukumpompa imizimba, iiflanges kunye nezinye iimveliso, kunye neentengiso zonyaka zibalwa kwi-25% yomthamo opheleleyo wokuthengwa komthengi.
Ixabiso leNtsebenziswano: Gubungela iimfuno ezixhasayo ngokubanzi zepetroleum, iikhemikhali, ivalve kunye namanye amashishini anensimbi engenasici echanekileyo yokuphosa kunye nomthamo wokuvelisa oguquguqukayo.
