Umuyoboro wa karubone udafite icyerekezo bivuga umuyoboro wakozwe mu byuma bya karubone udafite aho uhurira cyangwa udusudira, kandi fagitire ikomeye isohoka mu rupfu kugira ngo ikore umuyoboro wubunini nubunini bwifuzwa.Umuyoboro wa karubone udafite icyuma uzwi cyane kubera kuramba kwinshi, imbaraga zingana no kurwanya ruswa, bigatuma biba byiza mu nganda zitandukanye zirimo peteroli na gaze, amamodoka nubwubatsi.
Imwe mu ntera izwi cyane ya karubone idafite ibyuma niA106 Icyiciro B., nicyo gipimo cya ASTM kumuyoboro wa karubone idafite icyerekezo cya serivisi yubushyuhe bwo hejuru.Ifite karubone ntarengwa ya 0,30%, bigatuma iba nziza kubisabwa bisaba ubushyuhe bwinshi nigitutu.Irakwiriye kandi kumuvuduko muke hamwe nubushyuhe buke bwo gukoresha, kimwe no gusudira no gusya.
Ikindi cyiciro gikunzwe niAPI 5L Icyiciro B., nicyo gipimo cyumuyoboro wicyuma udafite kashe kandi usudira kuri sisitemu yo kohereza imiyoboro munganda za peteroli na gaze.Ifite karubone ntarengwa ya 0,30%, bigatuma iba nziza mugukoresha umuvuduko mwinshi hamwe nubushyuhe bwo hejuru bwa serivisi.
Usibye amanota, ibikoresho bya karubone idafite ibyuma nabyo ni ngombwa cyane.Ibikoresho bisanzwe birimo SAE 1020, ifite karubone nkeya kandi ikaba nziza mugikorwa cyo kugonda, guhinduranya no gukora ibintu bisa, hamwe na SAE 1045, ifite karubone nyinshi kandi nibyiza mubisabwa bisaba gukomera, gukomera no kurwanya kwambara.
Ibindi bikoresho birimo ASTM A519 Icyiciro cya 4130 kumirongo ya hydraulic yumuvuduko mwinshi hamwe no kuvoma peteroli, hamwe na ASTM A106 Grade C ifite karubone ntarengwa ya 0.35% kubisabwa bisaba kurwanya ruswa.
Mu gusoza, imiyoboro ya karubone idafite icyuma ningirakamaro mu nganda zitandukanye kandi guhitamo amanota nibikoresho biterwa nibisabwa byihariye.A106 Icyiciro B na API 5L Icyiciro B nicyiciro gikunzwe, mugihe ibikoresho nka SAE 1020, SAE 1045,ASTM A519 Icyiciro cya 4130, na ASTM A106 Icyiciro C ni amahitamo akunzwe.
