Umuyoboro w'icyuma udafite icyuma API5L GRB ni ibikoresho bisanzwe bikoreshwa mu byuma, bikoreshwa cyane muri peteroli, gaze n'inganda. "API5L" ni igipimo cyateguwe n'ikigo cya Amerika gishinzwe peteroli, kandi "GRB" yerekana urwego n'ubwoko bw'ibikoresho, ubusanzwe bikoreshwa mu miyoboro y'ingutu. Ibyiza by'imiyoboro y'icyuma idafite icyerekezo kiri mumikorere myiza yubukanishi no kurwanya ruswa, kandi birashobora gukora neza ahantu habi hamwe nubushyuhe bwinshi hamwe numuvuduko mwinshi.

Ibikoresho nyamukuru bigize imiti ya API5L GRB idafite ibyuma birimo karubone, manganese, sulfure, fosifore, nibindi, kandi bifite gusudira neza hamwe na plastike nyuma yuburyo bukomeye bwo gutunganya ubushyuhe. Ubu bwoko bw'icyuma bukoreshwa mu gutwara amazi na gaze, cyane cyane mugukoresha no gutwara imirima ya peteroli na gaze, kugirango umutekano urusheho kugenda neza.

ASTM A53, ASTM A106naAPI 5Lni ibintu bitatu bisanzwe bidafite icyerekezo cyicyuma, buri kimwe kibereye ibintu bitandukanye.

ASTM A53 ikoreshwa cyane cyane mubice nkimbaraga, ubwubatsi na peteroli. Umuyoboro wibyuma muriki gipimo ubereye umuvuduko muke hamwe nubushyuhe buke, kandi mubisanzwe bikoreshwa mugutwara amazi, gaze nandi mazi. Ifite imbaraga nziza no gusudira, kandi irakwiriye gukora imiyoboro itandukanye nibice byubatswe.

Ibipimo bya ASTM A106 byibanda cyane ku bushyuhe bwo hejuru hamwe n’umuvuduko mwinshi kandi birakwiriye inganda za peteroli na gaze. Imiyoboro y'icyuma idafite uburinganire bw'iki gipimo ikoreshwa cyane cyane mu gutwara amavuta, amazi ashyushye n'amavuta. Barashobora kugumana imiterere yubukanishi ku bushyuhe bwo hejuru kugirango umutekano n'umutekano bihamye.

Igipimo cya API 5L cyagenewe inganda za peteroli na gaze kandi kibereye imiyoboro yohereza umuvuduko mwinshi. Imiyoboro idafite ibyuma yujuje ubuziranenge ifite uburyo bwiza bwo kurwanya ruswa no kurwanya umuvuduko, bigatuma imikorere ikorwa neza mu bihe bikabije. Imiyoboro ya API 5L ikoreshwa kenshi mugukoresha no gutwara imirima ya peteroli na gaze kugirango itwarwe neza.

Ibipimo bitatu byimiyoboro idafite ibyuma bifite imiterere yabyo, ikubiyemo ibintu bitandukanye byakoreshwaga kuva kumuvuduko muke kugeza kumuvuduko mwinshi, kuva ubushyuhe buke kugeza ubushyuhe bwinshi, byujuje ibyifuzo bitandukanye byinganda, kandi bitanga ingwate kumutekano no gukora neza.
