28 Sano Warshada Shiinaha oo Tayada Sare leh Beeb Kaarboon Kaarboon ah
Baaritaanka Hydrostatic
Marka loo eego ASTM A106 tijaabada Hydrostatic ee caadiga ah waxaa loo sameeyaa mid mid. sida loo xisaabiyo xogta hydrostatic ee cabbir kasta?
Tusaale ahaan ASTMA106 GrB PSL 2 kaarboon birta birta ah 273*7mm
Xogta u qalantaa waa: 2*daqiiqo xoog dhalid *0.6 * dhumucda/ dhexroorka
sidaas ayay noqon doontaa:
2*245*0.6*7/273=7.5 MPa
Hadda ma garanaysaa ?

Shuruudaha Imtixaanka
Marka lagu daro hubinta isku dhafka kiimikada iyo sifooyinka farsamada, tijaabooyinka hydrostatic ayaa la sameeyaa mid mid, waxaana la sameeyaa tijaabooyinka fidinta iyo fidinta. . Intaa waxaa dheer, waxaa jira shuruudo gaar ah oo loogu talagalay qaab-dhismeedka yar-yar, cabbirka hadhuudhka, iyo lakabka decarburization ee tuubada birta ee dhammaatay.
