Dhuumaha ERW kulul iibinta tuubo bir tayo sare leh
Hordhac
Tuubbada ERW waa tuubo bir ah oo tollaynteeda ay la siman tahay jihada dheer ee tuubada birta. Caadi ahaan waxa loo qaybiyaa mitir koronto oo bir alxan ah, tuubo dhuuban oo koronto alxanaysa, tuubada saliidda qaboojiye iyo wixii la mid ah. Dhuumaha dhaadheer ee alxanka leh ayaa leh habka wax-soo-saarka fudud, waxtarka wax-soo-saarka sare, qiimo jaban iyo horumar degdeg ah. Awoodda tuubooyinka alxanka leh ee wareegsan ayaa guud ahaan ka sarreeya kuwa tolmada toosan ee tuubooyinka alxanka leh. Meel bannaan oo cidhiidhi ah ayaa loo isticmaali karaa in lagu soo saaro tubooyinka alxanka leh ee leh dhexroorka tuubooyinka, iyo billeed leh ballac la mid ah ayaa sidoo kale loo isticmaali karaa in lagu soo saaro tuubooyinka alxanka leh ee dhexroorka tuubooyinka kala duwan. Laakiin marka la barbar dhigo tuubada tolitaanka tooska ah ee isla dhererka, dhererka alxanka ayaa kordhay 30-100%, xawaaraha wax soo saarkuna wuu hooseeyaa.
