Tiyeni tiyambe ndi mfundo:
Mapaipi osapanga dzimbiri a Austenitic amagwiritsidwa ntchito m'malo osiyanasiyana owononga. Komabe, ngati mutasamala, mupeza kuti muzolemba zamayunitsi ena, bola ngati DN≤40, zida zamitundu yonse zimatengedwa. M'makalata opangira mayunitsi ena, mapaipi azitsulo zosapanga dzimbiri, ngakhale atakhala ang'onoang'ono bwanji, amagwiritsanso ntchito zida zopangira matako m'malo mwa ma chubu.
Monga mwambi umati: pofuna kuonetsetsa kuwotcherera khalidwe la mipope yaing'ono-caliber ndi kupewa kuwotcherera malowedwe pa kuwotcherera lalikulu panopa, kugwirizana zitsulo nthawi zambiri ntchito m'malo matako kuwotcherera kugwirizana. Nanga ndi chifukwa chiyani mayunitsi ena azitsulo zosapanga dzimbiri mapaipi ang'onoang'ono sakhala ndi tizidutswa ta intubation? Izi zikuphatikizapo vuto: dzimbiri paming'alu.
Tiye tikambirane kuti crevice corrosion ndi chiyani?
Pakakhala kusiyana (nthawi zambiri 0.025-0.1mm) pamwamba pa zigawo zachitsulo chifukwa cha matupi achilendo kapena zifukwa zapangidwe, zimakhala zovuta kusuntha zowonongeka zowonongeka mumpata, zomwe zimatsogolera ku dzimbiri zachitsulo, zomwe zimatchedwa gap corrosion. Kuwonongeka kwa mpata nthawi zambiri kumapangitsa kuti dzimbiri zina (monga corrosion, kupsinjika maganizo), motero polojekitiyo imayesetsa kupeŵa kuchitika kwa dzimbiri. Kukhalapo kwa ming'alu kuyenera kupewedwa popanga mapangidwe a mapaipi a sing'anga yomwe imakonda kuwononga dzimbiri.
Chitsulo chosapanga dzimbiri 304 flange
Ndi chifukwa pali kusiyana mu kugwirizana zitsulo, kotero ena mayunitsi pofuna kupewa dzimbiri kusiyana, chifukwa kukhalapo dzimbiri mipope zosapanga dzimbiri, payipi yaing'ono caliber nthawi zambiri ntchito matako kuwotcherera kugwirizana, kuwotcherera ndondomeko ulamuliro kuonetsetsa khalidwe, kupewa. kugwiritsa ntchito intubation.
304 ndi chitsulo chosapanga dzimbiri chapadziko lonse lapansi, chimagwiritsidwa ntchito kwambiri popanga zida ndi magawo omwe amafunikira magwiridwe antchito abwino (kukana dzimbiri ndi mawonekedwe).
304 chitsulo chosapanga dzimbiri ndi mtundu wachitsulo chosapanga dzimbiri chopangidwa motsatira miyezo ya ASTM ku United States. 304 ndi ofanana ndi chitsulo chosapanga dzimbiri cha China 0Cr19Ni9 (0Cr18Ni9). 304 ili ndi 19% chromium ndi 9% nickel.
304 ndi chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri, chosagwira kutentha. Amagwiritsidwa ntchito mu zida kupanga chakudya, xitong zida mankhwala, mphamvu nyukiliya, etc.
304 chitsulo chosapanga dzimbiri butt kuwotcherera flangendi chromium yomwe imagwiritsidwa ntchito kwambiri - chitsulo chosapanga dzimbiri cha nickel, chokhala ndi kukana bwino kwa dzimbiri, kukana kutentha, kutsika kwamphamvu kwa kutentha ndi mphamvu zamakina. Kukana kwa dzimbiri mumlengalenga, ngati kuli malo opangira mafakitale kapena malo oipitsidwa kwambiri, kumafunika kutsukidwa munthawi yake kuti zisawonongeke. Zoyenera kukonza chakudya, kusungirako ndi kunyamula. Ili ndi machinability wabwino komanso weldability. Kutentha kwa mbale, mvuto, katundu wapakhomo, zomangira, mankhwala, mafakitale a chakudya, etc.
