Habka wax soo saarka ee tuubooyinka alxanka wareegsan waxaa ku lug leh isticmaalka tignoolajiyada alxanka tuubooyinka ee horumarsan, iyadoo la soo saarayo tuubooyin alxan oo hal dhinac ah ama laba dhinac ah. Hawsha alxankani waxay hubinayaan cimri dhererka ugu badan iyo isku halaynta dhuumaha, oo awood u leh inay u adkeysato adkaantakhadka gaaska dabiiciga ah ee dhulka hoostiisa maragudbinta.

Xaruntayada wax soo saarka, waxaan dammaanad qaadaynaa in tuubooyinkayaga alxanka wareegsan ay maraan tijaabo tayo oo adag si loo hubiyo heerarka waxqabadkooda oo sarreeya. Waa muhiim in tuubooyinka alxanka ay buuxiyaan qawaaniinta tijaabada haydarooliga, xoogga laalaabka iyo sifooyinka laablaabashada qabow.
