API 5Lmuri rusange bivuga umuyoboro wibyuma (umuyoboro wumuyoboro) wo gushyira mubikorwa bisanzwe, umuyoboroumuyoboro w'icyumaharimo umuyoboro wicyuma udafite icyerekezo hamwe nicyuma gisudira ibyiciro bibiri. Kugeza ubu mumuyoboro wa peteroli twakunze gukoresha ibyuma bisudira ibyuma byubwoko bwa spiral bwarohamye arc welded pipe (SSAW), icyerekezo kigororotse cyarengewe arc gusudira umuyoboro (LSAW), imiyoboro yo gusudira irwanya (ERW), umuyoboro w'icyumaisanzwe ikoreshwa mumiyoboro ya diameter iri munsi ya 152mm.
Igipimo cy’igihugu cya GB / T 9711-2011 umuyoboro w’icyuma cya sisitemu yo gutwara imiyoboro mu nganda za peteroli na gaze cyakozwe hakurikijwe API 5L.
GB / T. Kubwibyo, ibipimo ngenderwaho bikurikizwa gusa kumiyoboro yicyuma idafite icyuma hamwe nicyuma gisudira cyogutwara peteroli na gaze, kandi ntabwo ikoreshwa mubyuma.
Ibyiciro by'icyuma
Ibyiciro by'ibyuma by'ibikoresho fatizo by'imiyoboro y'ibyuma by'uru rwego rwa API 5L ni GR.B, X42, X46, X52, X56, X60, X70, X80, n'ibindi. Ibyiciro by'ibyuma by'imiyoboro y'ibyuma biratandukanye, kandi ibisabwa ku bikoresho fatizo n'umusaruro nabyo biratandukanye, ariko ibingana na karubone hagati yibyuma bitandukanye bigenzurwa cyane.
Ibipimo byubuziranenge
Mubipimo bya API 5L, ubuziranenge (cyangwa ibisabwa) kumuyoboro wibyuma bigabanijwemo PSL1 na PSL2. PSL ni impfunyapfunyo yerekana urwego rwibicuruzwa.
PSL1 itanga urwego rusange rwibisabwa byujuje ubuziranenge; PSL2 yongeramo ibisabwa byingirakamaro kubigize imiti, gukomera gukomeye, imbaraga zingirakamaro, hamwe na NDEs.
