Mapaipi achitsulo a ASTM A671 CC65 CL 12 EFW: Mapaipi olumikizidwa mwamphamvu kwambiri ogwiritsidwa ntchito m'mafakitale

Chitoliro cha ASTM A671 CC65 CL 12 EFWndi chitoliro chapamwamba kwambiri cha EFW chomwe chimagwiritsidwa ntchito kwambiri mu mapaipi amafuta, gasi, mankhwala, ndi mafakitale ambiri. Mapaipi awa amakwaniritsa zofunikira zaMiyezo ya ASTM A671ndipo amapangidwira kunyamula madzi apakati ndi amphamvu komanso kugwiritsa ntchito kapangidwe kake. Amapereka kuthekera kolumikizana bwino komanso mphamvu zamakanika, zomwe zimapangitsa kuti akhale abwino kwambiri pakupanga mapaipi a mafakitale.

Kufotokozera Zinthu Zofunika

Mapaipi amapangidwa kuchokera ku alloy yochepachitsulo champhamvu kwambiri cha CC65, kapangidwe ka mankhwala kamayendetsedwa bwino kuti kapereke kuthekera kothira bwino, kukana dzimbiri komanso kuthekera kotentha kwambiri. Chitsulocho chili ndi kapangidwe ka tirigu wofanana ndipo chimakwaniritsa zofunikira zambiri za kapangidwe ndi kupsinjika komwe kumagwiritsidwa ntchito m'mafakitale.

Kapangidwe ka Mankhwala

Kapangidwe ka Mankhwala (Miyezo Yachizolowezi)
Chinthu Kaboni (C) Manganese (Mn) Silikoni (Si) Sulfure (S) Phosphorus (P) Nikeli (Ni) Chromium (Cr) Mkuwa (Cu)
Zomwe zili mkati (%) 0.12–0.20 0.50–1.00 0.10–0.35 ≤0.035 ≤0.035 ≤0.25 ≤0.25 ≤0.25

Dziwani: Kapangidwe ka mankhwala enieni kamasiyana pang'ono pa gulu lililonse koma nthawi zonse amakwaniritsa miyezo ya ASTM A671 CC65 CL 12.

Katundu wa Makina

Katundu Mtengo
Kulimba kwamakokedwe 415–550 MPa
Mphamvu Yopereka ≥280 MPa
Kutalikitsa ≥25%
Kulimba kwa Impact Mayeso otsatira malamulo, omwe mungasankhe kuti akhudze kutentha kochepa akupezeka

Mapulogalamu

Mapaipi achitsulo a ASTM A671 CC65 CL 12 EFW amagwiritsidwa ntchito kwambiri mu:

  • Mapaipi a mafuta ndi gasi
  • Mapaipi opangira mankhwala
  • Machitidwe oyendera madzi amphamvu kwambiri
  • Ma boiler a mafakitale ndi osinthira kutentha
  • Zothandizira kapangidwe ka nyumba ndi zida zamakanika

Kulongedza ndi Kuyendera

Chitetezo: Mapeto a mapaipi otsekedwa, mafuta oletsa dzimbiri mkati ndi kunja, okutidwa ndi pepala loletsa dzimbiri kapena filimu ya pulasitiki

Kusonkhanitsa: Yomangiriridwa ndi mipiringidzo yachitsulo m'mitolo; zothandizira zamatabwa kapena ma pallets zimapezeka ngati mungafune

Mayendedwe: Yoyenera kutumizidwa mtunda wautali kudzera panyanja, njanji, kapena msewu
