Shiinaha Alaab Cusub Shiinuhu Tayada Wanaagsan ee Buufida Rinjiga Birta ee Bilaashka ah
Dulmar
ASTM A106Gr.B Dhuumaha birta ah ee aan kala go'a lahayn waa bir kaarboon yar oo si weyn loo isticmaalo, taas oo si weyn looga isticmaalo warshadaha batroolka, kiimikaadka, iyo kuleyliyaha.Maaddadu waxay leedahay sifooyin farsamo oo wanaagsan.Inta badan waxaa loo isticmaalaa in lagu qaado dareerayaasha heerkulka sare sida biyaha, saliidda, gaaska, iwm.
ASTM A106 tuubooyin bir la'aan ah waxay ka kooban tahay laba hab oo kala ah: qabow soo jiiday iyo duub kulul.
Codsiga
Dhuumaha birta ah ee aan fiicnayn ee hawlgalka heerkulka sare ASTM A106, oo ku habboon heerkulka sare
Fasalka ugu weyn
Fasalka birta qaab dhismeedka tayada sare leh: GR.A,GR.B,GR.C

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.
