Qashinka lagu gubayo Foornada shabaggeedii Foornada
Tuurista kuleylka u adkeysata waxaa caadi ahaan laga sameeyaa birta birta ah ee leh tiro aad u tiro badan oo Chromium iyo Nickel ah. Tuurista laga sameeyay aaladaha kuleylka u adkaysta ayaa ku fiican qaybaha ka soo baxa gaasaska qalalan ee heerkulka sare muddo dheer. Warshadaha ka faa’iideysanaya shubista u adkeysiga kuleylka waxaa ka mid ah Tamarta, Matoorada, Foornooyinka / Foornooyinka, iyo Petrochemical.
Daaraha birta adkaysi u leh ayaa sidoo kale loo yaqaannaa qiiqa birta adkaysi u leh, shubka birta diidan, kuleylka u adkeysiga u adkeysiga birta.
Birta kuleylka u adkeysata waa nooc ka mid ah birta daawaha ah oo leh awood farsamo sare iyo xasiloonida kiimikada ee heerkulka sare.
Tuurista birta u adkaysta kulaylka ayaa loo isticmaalay in lagu sameeyo qaybaha kuleylka u adkaysta foornada warshadaha, kuleylka wax lagu beddelo, foornada kuleylka kuleylka leh, qaboojiyaha shabagga ah iyo qalabka kale ee warshadaha kuleylka u adkaysta.
Heerka ASTM A297 wuxuu daboolayaa birta-chromium iyo birta-chromium-nikkel daawaha loogu talagalay adeegga u adkeysiga kuleylka, buundooyinka ay daboosho ASTM A297 waa iskudhaf guud oo isku day ah lamana sameynin in lagu daro aaladaha iska caabinta kuleylka ee loo isticmaalay codsi wax soo saar gaar ah.
XTJ waxay ku faantaa inay bixiso kuleylka birta u adkeysanaya ee si buuxda u buuxiya heerka ASTM A297, oo ay ku jiraan:
• ASTM A297 Fasalka HF, Nooca 19Cr-9Ni
• ASTM A297 Fasalka HH, Nooca 25Cr-12Ni
