8 Sano Dhoofiyaha Cadaadiska Sarreya Biyo-qaade aan Xumaan lahayn
Sharaxaad Gaaban:
20G tuubo bir ah oo aan kala go 'lahayn waa bir qaabdhismeed tayo sare leh, walxo kuleyliyaha, kaarboonka 0.17-0.24%, xoogga xajinta ee 410Mpa, dhibicda 230-250Mpa.Miyuu yahay wax-soo-saarkayaga ugu weyn ee birta, waxaan ku siin karnaa 20G tuubo aan cillad lahayn oo leh tayo sare iyo qiimo tartan leh.Halkan si aan kuugu baro 20G tuubooyin aan sina lahayn sifooyinka kiimikada aasaasiga ah iyo sifooyinka farsamada.
Waxaan ku tiirsanahay fikirka istiraatijiyadeed, casriyaynta joogtada ah ee dhammaan qaybaha, horumarka tignoolajiyada iyo dabcan shaqaalaheena si toos ah uga qaybqaata guushayada 8 Sano dhoofiyaha Cadaadiska Sarreya Biyo-qaade aan Xirnayn aad xor u ah inaad nagula hadasho abaabulka.Waxaan aaminsanahay inaan la wadaagno khibradda ganacsi ee ugu faa'iidada badan dhammaan baayacmushtarkeenna.
