Carbon steel pipekukanganisa kwemukati kunogadzirwa mu carbon steel smelting defect smelting uye kukanda maitiro, zvakadai sekuparadzanisa, kwete-metallic inclusions, porosity, shrinkage uye kuputika.

Kusarurana

Segregation ndiko kusaenzana kugoverwa kwemakemikari anoumbwa musimbi, kunyanya zvinhu zvinokuvadza zvakadai sesarufa, phosphorus kuwedzera muingot.

Non-metallic inclusions

Non-metallic inclusions inoreva zvisiri-metallic inclusions musimbi ine tsvina yakaita sesulfides uye oxides.

Stomata

Stomata inoreva simbi uye kabhoni monoxide gasi mhedzisiro inogadzirwa mukudururwa haigone kupukunyuka zvizere uye kugara mudiki pores muingot.

Shrinkage

Shrinkage inokonzerwa nemvura yesimbi ingot mold kubva kunze kusvika mukati, iyo vhoriyamu chibvumirano panguva yekusimbisa pasi-kumusoro, nokuti nhanho inodonha, iyo yekupedzisira kusimba kwezvikamu zvesimbi haigoni kuwedzerwa kuumba.

Mutswe

Kugadziriswa kwesimbi yemvura muhurongwa nekuda kwezvikonzero zvakasiyana-siyana kushushikana, kutsemuka kwemakakatanwa kunogona kuoneka zvikamu zvakakura.
