GB / T 9711Puas yog ib tus qauv Suav teb rau "roj av lag luam - steel yeeb nkab rau pipelines- kev ua haujlwm." TusL360Qeb, sib npaug rau API 5L X52 qib, yog qhov siab {2} {{{{{{{}}}} alloyed steel dav siv nyob rau hauv lub zog sector. Tus "l" sawv ntsug rau "kab yeeb nkab," thiab "360" qhia nws li tsawg zog muaj zog ntawm 360 MPA.
1. Thawj siv thiab cov ntawv thov
GB / T 9711 L360 Steel Yeeb Nkab Siv Hauv Kev Tsim Nyob Ntev {2} {}}}} Siab Rights rau kev thauj mus los ntawm roj thiab nkev. Nws cov kev siv tshwj xeeb suav nrog:
Onshore thiab ntug hiav txwv kis pipelines:Ua li txoj leeg loj los thauj cov roj av, cov khoom ua kom zoo, thiab roj av los ntawm cov khoom lag luam ntau lawm, thiab cov khoom siv hluav taws xob.
Sau Cov Kab:Kev ntim cov roj lossis roj los ntawm ntau lub qhov dej thiab thauj lawv mus rau qhov chaw ua haujlwm nruab nrab.
Lub Nroog Rooj Zaum Chaw Nres Nkoj thiab Dispisation Networks:Siv nyob rau hauv cov ntu yuav tsum muaj lub zog siab dua los tiv thaiv sab hauv siab.
Cov ntawv thov txheej txheem:Muaj qee kis, nws tuaj yeem siv rau cov qauv txhawb nqa hauv cov teeb meem hluav taws xob lossis cov raj xa dej uas muaj cov khoom siv tshwj xeeb.
2. Cov ntsiab lus tseem ceeb thiab cov txiaj ntsig
Qhov ntau ntawm kev saws me nyuam ntawm L360 yog vim nws cov khoom seem zoo tshaj plaws ntawm cov khoom, uas yog qhov tseem ceeb rau kev nyab xeeb, ua haujlwm ntawm cov raj hluav taws xob.
Lub zog siab thiab tawv:Nrog tsawg kawg vim muaj lub zog ntawm 360 MPa, L360 tuaj yeem tiv thaiv lub siab sab hauv, tso cai rau kev thauj khoom loj dua ntawm cov kua ntev dua. Nws tseem muaj cov kev cuam tshuam zoo zoo, uas yog qhov tseem ceeb rau kev tiv thaiv tawg pleb tsis txaus siab, tshwj xeeb tshaj yog nyob rau hauv qis-}} qhov chaw ib puag ncig.
Zoo heev Weldability:Cov tshuaj lom neeg muaj pes tsawg leeg ntawm L360 yog ua tib zoo tswj (nrog rau cov roj ntsha sib npaug - ce). Qhov no ua rau nws haum rau ntau hom vuam siv hauv kev tsim kho hauv kev tsim kho, xws li kev sib tw siv hluav taws xob, ua rau muaj zog thiab txhim khu kev qha pipeline pob qij txha.
Zoo deformisity:Nws muaj qhov sib luag sib luag uas tso cai rau nws tiv thaiv hauv av, thiab cov nra hnyav tsis muaj qhov tseem ceeb rau kev sib cav sib ceg ntau dua ntau hom av.
Corrosion Kuj:Thaum tsis muaj hlau steel, L360 kav yog feem ntau siv nrog sab nraud los tiv thaiv corrosion thiab sab hauv av / marine ib puag ncig lub neej.
Tus nqi - ua tau zoo:Raws li micro -} Alloy almoyed nws lub zog siab xws li Niobium (NB) thiab Vanadium (es tsis muaj kev kho mob kub. Qhov no ua rau nws xaiv kev lag luam rau loj-} teev pipeline cov phiaj xwm.
Cov qauv thiab kev ntseeg tau:Raug tsim tawm mus rau txoj hlua khi GB / T 9711 (uas yog qhov ua tau zoo, thiab kev ua tau zoo sib xws, uas tsis yog kev nyab xeeb rau kev nyab xeeb infrastrastructure.
3. Kev txhim kho vaj tswv yim thiab yav tom ntej sib
Lub neej yav tom ntej rau GB / T 9711 L360 Steel Yeeb Nkab tseem ci, los ntawm Ntiaj Teb thiab txoj kev txhim kho cheeb tsam thiab kev nce qib thev naus laus zis.
Kev xav tau kev thov los ntawm Zog Infrastructure:Qhov hloov pauv thoob ntiaj teb, suav nrog Tuam Tshoj txoj kev ruaj ntseg Zog, txuas ntxiv cia siab rau cov pa roj cua sov {}} hlawv cov roj. Qhov no drives kev tsim kho tshiab thiab kev txij nkawm ntawm cov tes hauj lwm uas twb muaj lawm, ua kom ruaj khov kho cov qhab nia zoo li L360.
Sib cav nrog "txoj siv thiab txoj kev" teg num "Muaj ntau cov haujlwm hauv cov haujlwm hauv cov roj hauv cov roj thiab roj pipelines hla Central Asia, Middle East, thiab lwm thaj chaw. GB / T 9711 L360, raws li ib qho tseem ceeb Suav cov khoom lag luam, yog zoo {{}} positioned siv nyob rau hauv cov phiaj xwm thoob ntiaj teb no.
Kev nce qib hauv kev tsim cov tshuaj yeeb:Kev txhim kho txuas ntxiv rau hauv cov thev naus laus zis ntau dua, cov kav dej tsis yeem ua rau muaj kev sib tsoo (TMCP ntxiv rau cov ntawv thov Sulf.
Tsom rau kev nyab xeeb thiab ib puag ncig cov qauv:Raws li kev nyab xeeb thiab ib puag ncig cov kev sib koom ua ke ua stricter, cov ntawv pov thawj thiab ua kom zoo nkauj - Cov yeeb nkab ua raws li qhov tseem ceeb. Nws lub luag haujlwm hauv kev tiv thaiv kev txeej thiab ua kom muaj kev nyab xeeb thauj ntawm hydrocarbons yuav khaws nws ntawm qhov chaw xaiv.
Kev sib tw thiab kev sib tw nrog cov qhab nia siab dua:Thaum muaj ib tug qauv ntawm kev siv ntau dua - lub zog kawm nyob rau hauv loj {} {} {} Tus nqi piv txwv yog qhov zoo tshaj plaws, tshwj xeeb Hauv nruab nrab {{8} h siab kis thiab xa cov network.
