Chifukwa chiyani mitengo ya A105 ndi Q235 ili yosiyana?

Mpweya wachitsulo wa carbon umagwiritsidwa ntchito kwambiri poika mapaipi amadzimadzi a mafakitale.q235 ndiA105 ndi mitundu iwiri ya zida za carbon zitsulo zomwe zimagwiritsidwa ntchito kwambiri.Komabe, mawu awo ndi osiyana, nthawi zina osiyana kwambiri.Ndiye pali kusiyana kotani pakati pawo?Kodi pali kusiyana kotani pakati pa mitengo yawo?

Choyamba, Q235 carbon steel flange ndi flange wamba yosankhidwa ndi ogula ambiri chifukwa cha mtengo wake wotsika.Q235 nthawi zambiri amagwiritsa ntchito kutentha kwa -10 ~ 350 ℃.Kuphatikiza apo, Q235 nthawi zambiri imafuna kukakamiza kwapangidwe kochepera 3.0MPa.Pankhani yogwiritsa ntchito,

Q235 carbon steel flange nthawi zambiri amagwiritsidwa ntchito pa sing'anga yamapaipi omwe siapoizoni komanso osayaka, ndipo amagwiritsidwanso ntchito pazitsulo zamapangidwe, monga zomangira ndi zopachika, ndi zina zotero, koma Q235 sidzagwiritsidwa ntchito pa hydrocarbon ya liquefied, ndi mlingo wa kawopsedwe kwambiri ndi woopsa kwambiri sing'anga.

Carbon steel flange imapangidwa ndi zinthu za Q235.Dziwani kuti izi zikutanthauza kupanga Q235, chifukwa mbale yachitsulo ya Q235 yokhuthala imatha kugwiritsidwa ntchito mwachindunji ngati flange, koma magwiridwe ake ndi otsika pang'ono kuposa kupanga.Makamaka chifukwa cha kusiyana kwa mkati mwa kristalo, zomwe zimakhala zovuta kusiyanitsa pakati pa kupanga ndi ntchito.Magwero a Q235 ndi chifukwa mphamvu zokolola zili pamwamba pa 235, mphamvu zokolola zomwe zimayesedwa muzinthu zamakina zimakhala pamwamba pa 245, ndipo mphamvu yowonjezereka ili pamwamba pa 265.

A105 carbon steel flangendi wamba American muyezo mpweya zitsulo chuma, wamba structural zitsulo, kuphatikizapo zitsulo mbale, mbiri zitsulo, etc. Manganese ake okhutira ndi mkulu, ndi kuzungulira zitsulo chuma amatchedwa 20Mn.Zitha kuwoneka kuti zomwe zili mkati mwake ndizokwera pambuyo pa manganese.Kuyambira nthawi imeneyo, mphamvu zake zolimba komanso zokolola zidzakhala zapamwamba, ndipo mphamvu zake zonse zamakina zidzakhala bwino.Mphamvu zokolola zenizeni za zinthu za A105 pansi pamiyezo wamba ndizoposa 300, ndipo mphamvu zamakokedwe zimaposa 500.

Pogulitsa kunja kwa China kumayiko akunja, makasitomala ambiri akunja ndi ogula amasankha zinthu zamtundu wamba za American standard A105.Ngati pali zipangizo zina, ndemanga zapadera zidzapangidwa.
