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.

Kuoma Muedzo:

Papombi yeMagiredhi P91, P92, P122, uye P911, Brinell, Vickers, kana Rockwell kuomarara bvunzo ichaitwa pamuenzaniso kubva mujeti rega rega.

Bend Test:

Yepombi ine dhayamita inodarika NPS 25 uye iyo dhayamita kusvika kumadziro ukobvu reshiyo iri 7.0 kana zvishoma ichaiswa pakuyedzwa kwekubhenda pachinzvimbo cheyedzo yekubata kumeso. Imwe pombi ine dhayamita yakaenzana kana kudarika NPS 10 inogona kupihwa bvunzo yekubhenda panzvimbo yebvunzo yekubata kumeso zvichienderana nemvumo yemutengi.
