Manufacturing Nzira

(1)Nzira yekunyungudutsa simbi
GB 5310 20MnG simbi ichanyungudutswa nechoto chemagetsi pamwe nekunatsa muchoto, okisijeni inoshandura pamwe nekunatsa muchoto kana electroslag remelting nzira.

(2) Nzira dzekugadzira uye zvinodiwa kune chubhu blanks
Iyo chubhu isina chinhu inogona kugadzirwa nekuramba ichikandira, kufa kukandira kana kupisa kukungurukira (forging).

(3)Kugadzira nzira yesimbi chubhu
GB 5310 20MnG Simbi machubhu anozogadzirwa nekupisa kutenderedza (extrusion, kuwedzera) kana kutonhora kudhirowa (kukunguruka).

Test Chinodiwa

Hydraustatic Test:
Iyo Pipe Yesimbi Inofanirwa Kuedzwa Hydraulically One by One.Iyo Yakakura Muyedzo Kudzvanya ndeye 20 MPa.Pasi Pekumanikidzwa Kuedzwa, Nguva Yekudzikamisa Inofanira Kuve isingasviki 10 S, Uye Pipe Yesimbi haifanirwe Kudonha.
Mushure mekunge Mushandisi Abvuma, Iyo Hydraulic Test Inogona Kutsiviwa neEddy Yazvino Kuedza Kana Magnetic Flux Leakage Testing.

Nondestructive Test:
Mapaipi Anoda Kuongororwa Kwakawanda Anofanirwa Kuongororwa Nema Ultrasonically One by One.Mushure mekunge Nhaurirano Inoda Mvumo yeBato uye Yakatsanangurwa Muchibvumirano, kumwe Kuedza Kusina Kuparadza Inogona Kuwedzerwa.

Flattening Test:
Machubhu Ane Dhiyamita Yekunze Yakakura Kupfuura 22 Mm Achaiswa Kumuyedzo Wekutsetseka.Hapana Inooneka Delamination, White Spots, kana Kusachena Kunofanira Kuitika Panguva Yese Yekuyedza.

Flaring Test:
Zvinoenderana Nezvinodikanwa zveMutengi Uye Zvakataurwa MuKondirakiti, Iyo Pipe Yesimbi Ine Outer Diameter ≤76mm Uye Kukora Kwemadziro ≤8mm Inogona Kuitwa Flaring Test .Kuedza kwacho kwakaitwa Pakamuri Tembiricha Netepi ye60 °.Mushure meKupenya, Mwero weKupisa weDimita Yekunze Unofanirwa Kusangana nezvinodiwa zveTafura inotevera, uye Chiyedzo Chiyedzo hachifanirwe kuratidza Makatsemuka kana mbabvu.
