API 5L X60 (L415) numuyoboro wumurongon'imbaraga ntoya zingana na 60,200 (415 MPa) kugirango ikoreshwe muri sisitemu yo gutwara imiyoboro munganda za peteroli na gaze.
X60Irashobora kuba idafite icyerekezo cyangwa ubwoko bwinshi bwicyuma gisudira, mubisanzwe LSAW (SAWL), SSAW (SAWH), na ERW.
Bitewe n'imbaraga zayo nyinshi kandi biramba, umuyoboro wa X60 ukoreshwa kenshi mumiyoboro ndende ihuza uturere cyangwa imirimo yo gutwara abantu binyuze mubutaka bugoye nibindi bidukikije bisaba.
Botop Steelni uruganda rukora uruganda rukomeye ruzengurutse urukuta runini rwa diametero ebyiri zirengerwa arc LSAW ibyuma biherereye mubushinwa.

Ibisabwa
Ukurikije uburyo bwo gutanga no kurwego rwa PSL, X60 irashobora gushyirwa mubyiciro bikurikira ：
PSL1: x60 cyangwa L415;
PSL2: X60N, X60Q, X60M cyangwa L415N, L415Q, L415M.
N: Yerekana ubusanzwe ibikoresho.Mu gushyushya ibyuma kubushyuhe runaka bikurikirwa no gukonjesha ikirere.Gutezimbere microstructure hamwe nubukanishi bwibyuma no kongera ubukana no guhoraho.
Q: Ibihagararo byo kuzimya no gutereta.Kugabanya ibyuma ubishyushya ubushyuhe runaka, bikonjesha vuba, hanyuma ukongera kubishyushya ubushyuhe buke.Kugirango ubone impirimbanyi yimiterere yihariye, nkimbaraga nyinshi no gukomera.
M: Yerekana ubuvuzi bwa termo-mashini.Gukomatanya kuvura ubushyuhe no gutunganya kugirango microstructure hamwe nimiterere yibyuma.Birashoboka kongera imbaraga nubukomezi bwibyuma mugihe ukomeza ibintu byiza byo gusudira.
API 5L X60 Uburyo bwo gukora
Inzira yemewe yo gukora ibyuma bya X60
Niba ubona aya magambo ahinnye bigoye kubyumva, reba icyegeranyo cyingingo kuriamagambo ahinnye yimiyoboro yicyuma.
Ibyiza bya SAWL (LSAW)
Niba ukeneye umubyimba munini wa diametre wurukuta rw'icyuma, icyambere niSAWL (LSAW) umuyoboro w'icyuma. Umuyoboro w'icyuma wa LSAW urashobora gukorwa mubunini bugera kuri 1500mm z'umurambararo na 80mm z'ubugari bw'urukuta, rushobora rwose guhaza ibyifuzo by'imiyoboro miremire ku mishinga minini.
Mubyongeyeho, mugihe cyibikorwa byo gukora, umuyoboro wicyuma wa LSAW ukoresha impande zombi zashizwemo arc gusudira (DSAW) inzira, yemeza ubwiza bwikidodo.
API 5L X60 Ibigize imiti
PSL1 iroroshye cyane kuruta PSL2 mubijyanye nimiterere yimiti, imiterere yubukanishi, nibindi bisabwa.
Ni ukubera koPSL1byerekana urwego rusanzwe rwubuziranenge kumuyoboro wibyuma, mugihePSL2Birashobora kugaragara nka verisiyo yazamuye ya PSL1, itanga ibisobanuro birambuye kandi bigenzura neza.
Ibigize imiti ya PSL 1 Umuyoboro ufite t ≤ 25.0 mm (0,984 muri.)
Ibigize imiti ya PSL 2 Umuyoboro ufite t ≤ 25.0 mm (0,984 muri.)
Kubicuruzwa bya PSL2 ibyuma bisesengurwa hamwe nakarubone ingana na 0,12%, karubone ihwanye na CEpcmirashobora kubarwa ukoresheje formula ikurikira:
CEpcm= C + Si / 30 + Mn / 20 + Cu / 20 + Ni / 60 + Cr / 20 + Mo / 15 + V / 15 + 5B
Kubicuruzwa bya PSL2 ibyuma bisesengurwa hamwe naibirimo karubone> 0,12%, karubone ihwanye na CEllwirashobora kubarwa ukoresheje formula ikurikira:
CEllw= C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
Ibigize imiti hamwe na t ＞ 25.0 mm (0,984 muri.)
Bizagenwa nu mishyikirano kandi bihindurwe muburyo bukwiye hashingiwe kubisabwa imiti yavuzwe haruguru.
