Ibisobanuro bisanzwe

API 5L muri rusange yerekeza kubikorwa byo gukora kumurongo. Umuyoboro wumurongo urimo imiyoboro yicyuma idafite imiyoboro hamwe nicyuma 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.

Igipimo ngenderwaho cyigihugu GB / T 9711-2011 Imiyoboro yicyuma ya sisitemu yo gutwara imiyoboro ya peteroli na gaze yakozwe hifashishijwe API 5L.

GB / T 9711-2011 irerekana ibikenerwa mu gukora imiyoboro idafite ibyuma hamwe n’icyuma gisudira mu byiciro bibiri byerekana ibicuruzwa (PSL1 na PSL2) bikoreshwa muri sisitemu yo gutwara imiyoboro ya peteroli na gaze. 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.

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.

Kugereranya ubuziranenge

1.Ubuziranenge bwa PSL2 burenze ubwa PSL1. Izi nzego zombi zisobanurwa ntabwo zifite gusa ibisabwa bitandukanye byo kugenzura, ariko kandi zifite ibisabwa bitandukanye mubigize imiti hamwe nubukanishi. Kubwibyo, mugihe utumije ukurikije API 5L, ibikubiye mumasezerano ntibigomba kwerekana gusa ibisobanuro, amanota yicyuma, nibindi. Usibye ibipimo bisanzwe, urwego rwibicuruzwa rugomba no kwerekanwa, ni ukuvuga PSL1 cyangwa PSL2. PSL2 irakomeye kurusha PSL1 mubijyanye nimiterere yimiti, imiterere ihindagurika, ingufu zingaruka, ibizamini bidasenya nibindi bipimo.

2. PSL1 ntabwo isaba imikorere yingaruka. Ibyiciro byose byicyuma cya PSL2 usibye icyiciro cya X80 cyicyuma, ubunini bwuzuye 0 ℃ Akv ugereranije: uburebure bwa ≥101J, transvers ≥68J.

3. Imiyoboro y'umurongo igomba kugeragezwa kumuvuduko wa hydraulic umwe umwe, kandi urwego ntiruteganya ko gusimbuza umuvuduko wamazi bidasenya. Iri kandi ni itandukaniro rinini hagati yubuziranenge bwa API nubushinwa. PSL1 ntisaba ubugenzuzi budasenya, mugihe PSL2 isaba ubugenzuzi budasenya umwe umwe.
