Kukana kwake kwakukulu kufooka, kucha kwa carburization, ndi kuchuluka kwa makuti kumapangitsa kuti zikhale zodalirika m'malo okwezeka.
Kalasi iyi ya chitsulo chosapanga dzimbiri imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito mafakitale ambiri komanso ndi yabwino kugwiritsa ntchito komwe anthu ambiri ndi oxidation amafunikira kwenikweni.
Miyezo ndi zojambula
AAstm A312 S30815 253Ma duel Chitoliro chachitsuloAmapangidwa molingana ndi mfundo zotsatirazi:
- ASTM A312: Mudzi wofanana wa osawoneka, owala, komanso ozizira kwambiri matope achitsulo osakhazikika
- S30815: Dongosolo lolumikizidwa lolumikizidwa lazinthu zomwe zimazindikiritsa izi ngati kalasi yapamwamba kwambiri yosapanga dzimbiri.
- En 10088-2: Muyezo wa ku Europe kwa chitsulo chosapanga dzimbiri, chophimba zofunikira pazinthu zazinthuzi, makina, komanso kuyezetsa.

Njira Zopangira: Zojambulajambula za Kulondola
Kupanga kwaMapaipi achitsulo osapanga dzimbiriamatsatira njira zopangira zaposachedwa kuti zitsimikizire kuti ndi zapamwamba komanso zolimba:
- Chipika chopanda pake: Kupangidwa kudzera pakuboola, kuboola kozungulira, ndi njira za mlengalenga kuti zipangire mapaipi osawoneka ndi khoma la makulidwe.
- Kuchita Kuchita Bwino: Zojambula kapena zojambula zozizira kapena njira zomwe zimagwiritsidwa ntchito zimagwiritsidwa ntchito kuti mukwaniritse kukula kolondola komanso malo osalala.
- Chithandizo cha kutentha: Mapaipi amakumana ndi kutentha mankhwalawa kutentha kwapadera kuti apititse mphamvu zawo ndi kutentha kwambiri.
- Kusankha & Pass: Mapaipi amasankhidwa kuti achotse kukula ndi mafilimu okutira ndi omwe ajambulidwa kuti atsimikizire kukana kuwonongera.
Kuyesa ndi Kuyendera: Chitsimikizo Chachikhalidwe
Zitsulo zachitsulo zimatsata protocol yoyeserera kuti iwonetsetse bwino kwambiriMapaipi achitsulo osapanga dzimbiri:
- Kusanthula kwamankhwala: Zotsimikizika pogwiritsa ntchito njira zoperekera mawonekedwe kuti mutsimikizire kuti alloy amakwaniritsa nyimbo.
- Kuyezetsa kwamakina: Tansiile, kuuma, ndi kuyezetsa kuyesa kutsimikizira zochita zakunja kwa kutentha kosiyanasiyana.
- Kuyesa kwa Hydrostatic: Mapaipi amayesedwa kuti akakamize kukhazikika kwaulere.
- Kuyesa kowononga (NDT): Kuphatikiza akupanga, Eddy pakalipano, ndi utoto woyeserera kuti awone zolakwika zamkati kapena zapamwamba.
- Zowoneka & Zowoneka Mwazo: Chitoliro chilichonse chimayang'aniridwa kuti chimaliziro chakumapeto, ndipo kulondola kwa kukula kumayang'aniridwa motsutsana ndi mawonekedwe.
Kuti mumve zambiri kapena mawu achizolowezi, kulumikizana ndi chitsulo masiku ano!
