Ibiranga:
Ubusobanuro buhanitse: nyuma yo gusya neza neza, diameter ya bore hamwe nubuso bwubuso bigenzurwa cyane kugirango harebwe ibipimo nyabyo nibiranga geometrike.
Ubuso bworoshye: nyuma yo gusya kuvura, hejuru ya bore iroroshye, igabanya guterana no kwambara, ifasha kwanduza amazi no gukora sisitemu.
Ibyiza bya Mechanical Properties: Ubutaka bwa bore ibyuma bisanzwe bifite imiterere yubukanishi nubuzima bwumunaniro bitewe no kugabanuka kumaganya mugihe cyo gusya.
Birashobora guhindurwa cyane: amahitamo yihariye arahari mubikoresho bitandukanye, ingano, bore diameter yukuri hamwe n'ubuso bukabije ukurikije ibyo abakiriya bakeneye.
Andika ubutumwa bwawe hano hanyuma utwohereze
