Jumlada Shiinaha Shiinaha ASTM A53 A106 API 5L Dhuumaha Birta Kaarboon Alxanka Ah
Dulmar
Waxaan aaminsanahay in shuraakada ra'yiga dheeraatay ay dhab ahaantii ka dhalatay heerka ugu sarreeya, taageerada qiimaha lagu daray, kulan qani ah iyo xiriirka shakhsi ahaaneed ee tubada birta Kaarboon. Hubi in aad si xor ah ula soo xidhiidhi karto si aad macluumaad iyo xaqiiqooyin dheeraad ah u hesho. Waxaa naloo soo bandhigay sidii mid ka mid ah soo-saareyaasha soo koraya iyo dhoofinta birta kaarboon iyo birta daawaha. Hadda waxaan haynaa koox khibrad leh oo tababbaran oo daryeela tayada iyo sahayda waqtigeeda. Haddii aad ku raadinayso Tayo Wanaagsan qiimo wanaagsan iyo gaarsiin waqtigeeda. nala soo xidhiidh
A106 tuubo bir ah oo aan kala go 'lahayn waa tuubo bir ah oo aan xumi lahayn oo loo isticmaalo in lagu qaado dareeraha heerkulka sare sida biyaha, saliidda, iyo gaasta. Heerkan birta ah waxa uu leeyahay qallafsanaan qabow oo sarreeya iyo balaastiig sare, qabow soo jiiday ama xaalad caadi ah ayaa ka fiican gobolka la jeexjeexay, guud ahaan loo isticmaalo tuubooyinka dareeraha ah, tuubooyinka qaabdhismeedka, tuubooyinka kululeeyaha cadaadiska hooseeya oo aan cadaadis sare lahayn oo u baahan adag adag.

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 yaryar, cabbirka hadhuudhka, iyo lakabka decarburization ee tuubada birta ee dhammaatay.
