Qiimaha Jumladda Kulul ee ASTM A335 P91 tuubo daawaha birta ah oo qaro weyn leh oo loogu talagalay cadaadis sare iyo warshad koronto heerkulka
Dulmar
Waxaa naga go'an inaan gaarsiino si fudud, waqti-badbaadin ah iyo lacag-badbaadin hal-joojin kaalmada wax iibsiga ee macaamilka ee Qiimaha Jumladda Kulul ee aan toosnayn ASTM A335 P91 Dhuumaha daawaha birta qaro weyn ee cadaadiska sare iyo warshadda heerkulka, Waxaan u dhoofinay in ka badan 40 waddan iyo gobollo, kuwaas oo sumcad wanaagsan ka helay macaamiisheena adduunka oo dhan.
Waxaa naga go'an inaan gaarsiino si fudud, waqti-badbaadin ah iyo lacag-badbaadin hal-joojin kaalmada wax iibsiga ee macaamilka, Alaabadayada waxaa si weyn loo aqoonsan yahay oo lagu kalsoon yahay isticmaalayaasha waxayna dabooli karaan si joogto ah u kobcaya baahiyaha dhaqaale iyo bulsho. Waxaan soo dhawaynaynaa macaamiisha cusub iyo kuwa hore ee ka kala socda qaybaha kala duwan ee nolosha si ay nala soo xiriiraan xiriirka ganacsiga mustaqbalka iyo gaaritaanka guul wadaagga ah!
