FAQ
Kodi chitoliro cha ASTM A335 P92 n'chiyani?
Chitoliro cha ASTM A335 P92 ndi chitoliro chachitsulo chopanda ferritic chomwe chimapangidwa ndi chitsulo cholimba chomwe chimagwiritsidwa ntchito kutentha kwambiri. Chimagwiritsidwa ntchito kwambiri m'mafakitale apamwamba amagetsi, ma boiler, ma superheater, ma reheater ndi makina a nthunzi yothamanga kwambiri.
Kodi ASTM A335 P92 ndi yofanana ndi ASME SA335 P92?
ASTM A335 ndi ASME SA335 nthawi zambiri zimatchulidwa pamodzi pa chitoliro chachitsulo cha ferritic alloy chopanda msoko. Dongosololi liyenera kufotokoza momveka bwino ngati zofunikira za ASTM, ASME kapena code ya polojekiti zikugwira ntchito.
Kodi kusiyana pakati pa P91 ndi P92 ndi kotani?
P92 ndi chitsulo chapamwamba cha 9Cr chopangidwa kuchokera ku banja la zinthu za P91. Nthawi zambiri chimagwiritsa ntchito tungsten ndi microalloying yolamulidwa kuti chiwonjezere mphamvu yokwera kuti chigwiritsidwe ntchito kwambiri pamagetsi otentha kwambiri.
Kodi chitsulo chosapanga dzimbiri cha P92 ndi chiyani?
Ayi. P92 ndi chitsulo chosapanga dzimbiri chomwe chimateteza kutentha, osati chitsulo chosapanga dzimbiri. Ngakhale chili ndi chromium, chimafunikabe chitetezo choteteza dzimbiri panthawi yosungira ndi kunyamula.
Kodi chitoliro cha P92 chingalumikizidwe?
Inde, koma kuwotcherera kwa P92 kumafuna njira zowotcherera zoyenerera, kutentha koyenera, kutentha kolamulidwa pakati pa ma interpass ndi kutentha pambuyo pa kuwotcherera. Kuwotcherera kuyenera kutsatira malamulo oyenera ndi ndondomeko ya polojekitiyi.
Ndi mayeso ati omwe alipo pa chitoliro cha ASTM A335 P92?
Kuyesa kwa hydrostatic, kuyesa kosawononga, kuyang'anira miyeso, kuyesa kuuma, PMI ndi kuwunika kwa MTC kungakonzedwe malinga ndi dongosolo logulira ndi zofunikira zomwe zimafunika.
Kodi MTC ndi EN 10204 3.1 zingaperekedwe?
SAKY STEEL ikhoza kupereka zikalata za MTC ndi EN 10204 3.1 malinga ndi lamulo logulira. Malipoti ena owunikira amathanso kukonzedwa ngati atchulidwa.
