API 5L ni iki?

Muri rusange API 5L yerekeza ku gipimo ngenderwaho cyo gushyira mu bikorwa imiyoboro y'icyuma ikoreshwa mu miyoboro, kirimo ibyiciro bibiri by'ingenzi:imiyoboro y'icyuma idakora nezanaimiyoboro y'icyuma ishongeshejweMuri iki gihe, ubwoko bw'imiyoboro y'icyuma ikoreshwa cyane mu miyoboro ya peteroli niimiyoboro ikoze mu cyuma gishongeshejwe n'uruziga(UMUYOBORO WA SSAW),imiyoboro yometseho arc irekuye mu gihe kirekire(Umuyoboro wa LSAW), naimiyoboro ikoreshwa n'amashanyarazi ivanze n'amazi(ERW). Imiyoboro y'icyuma idakora neza ikunze gutoranywa iyo umurambararo w'umuyoboro uri munsi ya mm 152.

 

Igipimo ngenderwaho cy’igihugu cya GB/T 9711-2011, Imiyoboro y’Ibyuma ikoreshwa mu gutwara imiyoboro mu nganda za peteroli na gaze, cyakozwe hashingiwe kuri API 5L.

 

GB/T 9711-2011 igaragaza ibisabwa mu nganda ku miyoboro y'icyuma idakora kandi ivanze ikoreshwa mu buryo bwo gutwara ibikomoka kuri peteroli na gaze karemano, ikaba ikubiyemo urwego rubiri rw'ibicuruzwa (PSL1 na PSL2). Kubwibyo, iyi ngingo ikoreshwa gusa ku miyoboro y'icyuma idakora kandi ivanze yo kohereza peteroli na gaze kandi ntikoreshwa ku miyoboro y'icyuma ivanze.

 

Ibyiciro by'icyuma

Imiyoboro y'icyuma ya API 5L ikoresha imiterere itandukanye y'ibikoresho fatizo birimo GR.B, X42, X46, X52, X56, X60, X70, X80, n'ibindi. Ibyuma by'imiyoboro bifite imiterere ya X100 na X120 ubu byarakozwe. Imiterere itandukanye y'ibyuma ishyiraho ibisabwa bitandukanye ku bikoresho fatizo n'uburyo bwo kubitunganya.

 

Urwego rw'Ubuziranenge

Mu rwego rwa API 5L, ubuziranenge bw'icyuma cy'imiyoboro bushyirwa mu cyiciro cya PSL1 cyangwa PSL2. PSL isobanura urwego rw'ibicuruzwa.
PSL1 isobanura ibisabwa muri rusange ku buziranenge bw'icyuma cy'imiyoboro; PSL2 yongeraho ibisabwa ku miterere ya shimi, gukomera kw'imirongo, imiterere y'imbaraga, n'ibizamini by'inyongera bya NDE.
