Dulmar guud ee Tuubooyinka Birta Ductile
Waxaa laga sameeyay bir la shubay oo caadi ahaan loo isticmaalo gudbinta iyo qaybinta biyaha la cabbo oo cimrigeedu ka badan yahay 100 sano. Noocan tuubo waa horumar toos ah oo laga sameeyay tuubooyin hore oo bir ah oo la shubay, kaas oo uu beddelay. Ku habboon in dhulka hoostiisa lagu dhigo khadadka gudbinta ee ugu muhiimsan.
