Dulmar guud oo ku saabsan Tuubooyinka Birta Ductile
Waxay ka badan tahay 70 sano tan iyo markii la ikhtiraacay tuubooyinka birta ah ee ductile sanadkii 1940-meeyadii. Iyada oo leh xoog sare, dheereyn sare, iska caabin daxaleed, iska caabin shoog, dhismo fudud iyo astaamo kale oo badan oo wanaagsan, tuubada birta ah ee ductile waa doorashada ugu fiican adduunka maanta si loo gaarsiiyo biyaha iyo gaaska si badbaado leh. Birta Ductile, oo sidoo kale loo yaqaan birta nodular ama birta graphite ee spheroidal, waxaa lagu gartaa joogitaanka graphite spheroidal ee shubka ka dhashay.

Astaamaha Tuubooyinka Birta Ductile
Tuubooyinka birta ah ee tuubada lagu shubo waxaa laga heli karaa dhexroor kala duwan laga bilaabo 80 mm ilaa 2000 mm waxayna ku habboon yihiin gudbinta biyaha la cabi karo iyo qaybinta (sida waafaqsan BS EN 545) iyo wasakhda (sida waafaqsan BS EN 598). Tuubooyinka birta ah ee tuubada lagu shubo waa kuwo fudud in la isku xidho, waxaa la dhigi karaa xaaladaha cimilada oo dhan badanaana iyada oo aan loo baahnayn in la soo xulo buuxinta. Qodobka badbaadada sare iyo awoodda ay u leedahay inay la qabsato dhaqdhaqaaqa dhulka ayaa ka dhigaya agabka ugu habboon ee tuubooyinka loogu talagalay codsiyo badan.

Codsiyada Birta Ductile
Birta Ductile waxay leedahay xoog iyo dabacsanaan ka badan birta cawlan. Sifooyinkaasi waxay u oggolaanayaan in si wax ku ool ah loogu isticmaalo noocyo kala duwan oo warshadeed, oo ay ku jiraan tuubooyinka, qaybaha baabuurta, giraangiraha, sanduuqyada geerka, guryaha bamka, qaab-dhismeedka mashiinka ee warshadaha korontada dabaysha, iyo kuwo kale oo badan. Maadaama aysan jabin sida birta cawlan, birta ductile sidoo kale waa ammaan in loo isticmaalo codsiyada ilaalinta saameynta, sida bollards.
