Ibisobanuro bisanzwe
API 5Lmuri rusange bivuga ibipimo ngenderwaho kumiyoboro y'ibyuma. Umuyoboro w'icyuma urimo imiyoboro y'icyuma idafite icyerekezo hamwe n'icyuma gisudira. Kugeza ubu, ubwoko bw'icyuma gikoreshwa cyane mu miyoboro ya peteroli harimo umuyoboro wuzuye wa arc welded arc (SSAW), umuyoboro ugororotse wuzuye arc welded (LSAW), hamwe n'umuyoboro w'amashanyarazi (ERW). Imiyoboro y'icyuma idafite ubudodo ihitamo muri rusange iyo diameter ya pipe iri munsi ya 152mm.
Igihugu gisanzwe GB / T 9711-2011 Imiyoboro yicyuma ya sisitemu yo gutwara imiyoboro ya peteroli na gaze yakozwe hifashishijwe hashingiweAPI 5L.
GB / T. Kubwibyo, iyi ngingo ngenderwaho ikoreshwa gusa mubyuma bidafite ibyuma hamwe nu byuma bisudira byo gutwara peteroli na gaze, kandi ntibireba imiyoboro yicyuma.
Urwego rw'icyuma
Ibyuma byibanze byicyiciro cyaAPI 5Limiyoboro y'ibyuma irimo GR.B, X42, X46, X52, X56, X60, X70, X120 ibyuma. Ibyiciro bitandukanye byibyuma byicyuma bifite ibisabwa bitandukanye kubikoresho fatizo no kubyaza umusaruro, ariko karubone ihwanye nicyiciro cyibyuma bitandukanye iragenzurwa cyane.
Ubuziranenge
Mubipimo byicyuma cya API 5L, ubuziranenge (cyangwa ibisabwa) imiyoboro yicyuma igabanijwemo PSL1 na PSL2. PSL ni impfunyapfunyo y'ibicuruzwa byerekana urwego.
PSL1 itanga imiyoboro rusange yicyuma cyujuje ubuziranenge; PSL2 yongeramo ibyangombwa bisabwa mubigize imiti, gukomera, imbaraga zimbaraga hamwe na NDE yinyongera.
Icyiciro cyicyuma cya PSL1 umuyoboro wicyuma (izina ryerekana urwego rwimbaraga zumuyoboro wibyuma, nka L290, 290 bivuga imbaraga nkeya yumusaruro wumubiri wa 290MPa) nicyiciro cyicyuma (cyangwa urwego, nka X42, aho 42 byerekana imbaraga ntoya yumusaruro cyangwa uruziga ruzamuka Imbaraga ntoya yumusaruro wicyuma (muri psi) ni kimwe nicyuma cyicyuma y'umuyoboro w'icyuma, kandi urwego rw'icyuma rufitanye isano n'imiterere y'ibyuma.
Imiyoboro ya PSL2 igizwe ninyuguti cyangwa guhuza inyuguti nimibare ikoreshwa kugirango umenye urwego rwimbaraga zicyuma. Izina ryicyuma (urwego rwicyuma) rifitanye isano nimiterere yicyuma. Harimo kandi inyuguti imwe (R, N, Q cyangwa M) ikora umugereka, yerekana uko itangwa ryifashe. Kuri PSL2, nyuma yuburyo bwo gutanga, hariho kandi inyuguti ya S (ibidukikije bya serivisi ya aside) cyangwa O (ibidukikije bya marine) byerekana uko serivisi ihagaze.
