Incamake
ASTM A106Gr.B umuyoboro wicyuma udafite icyuma nicyuma gikoreshwa cyane nicyuma gito cya karubone, gikoreshwa cyane mubikorwa bya peteroli, imiti, n’ibyuka. Ibikoresho bifite imiterere myiza yubukanishi. Ahanini ikoreshwa mugutwara ubushyuhe bwo hejuru nkamazi, amavuta, gaze, nibindi.
ASTM A106 umuyoboro wicyuma udafite icyerekezo kirimo inzira ebyiri: gukonjesha gukonje no kuzunguruka.
Gusaba
Umuyoboro w'icyuma udafite icyerekezo cyo gukora ubushyuhe bwinshi ASTM A106, ikwiranye n'ubushyuhe bwo hejuru
Icyiciro rusange
