Taw qhia rau API 5L Gr.B tus qauv kev tswj hwm thiab cov txheej txheem yuav tsum tau ua
API 5L Gr.Byog ib tug nrov txheem steel yeeb nkab uas yog dav siv nyob rau hauv ntau industries.Baolaitau muag APL 5L Gr.B yeeb nkab rau lub sijhawm ntev thiab tau txais cov lus pom zoo los ntawm peb cov neeg siv khoom.
1. Gr.B: Qib B steel; Ua raws li API 5L tus qauv, tus qauv hauv tsev sib raug rau API 5L tus qauv yog GB / T9711 tus qauv, thiab Gr.B sib haum rau L245 cov khoom.
Pipeline steel yog hais txog ib hom hlau uas yuav tsum tau tshwj xeeb rau cov kav dej siv los thauj cov roj thiab cov nkev. Raws li qhov sib txawv ntawm thickness thiab tom qab tsim, nws tuaj yeem tsim los ntawm kub tandem dov mills, Steckel mills, los yog phaj mills. Kauv vuam lossis UOE ncaj seam vuam los tsim cov kav hlau loj.
High-temperature thiab high-pressure alloy steel kav rau cov kav dej loj, cov yeeb nkab fittings, bypass systems, thiab lwm yam. , thiab thoob ntiaj teb GB series.
Pipeline steel yog cov phaj hlau rau cov kav dej, feem ntau yog siv rau kev ua thiab tsim cov roj thiab cov kav dej. Nyob rau hauv tus txheej txheem ntawm kev siv, ntxiv rau siab compressive zog, hilow-temperatureure toughness thiab zoo heev vuam kev ua tau zoo kuj yuav tsum tau.
2. Kev siv tshuab hauv tsev
Cov phaj tuab tuab thiab cov coils siv rau hauv kev tsim cov roj, kev sib sau ua ke, thiab cov kav dej ntev lossis cov thee, cov khoom siv hauv tsev slurry pipelines, thiab lwm yam yog hu ua pipeline steel (steel lossis pipeline). Feem ntau, nruab nrab thiab tuab daim hlau yog siv los ua cov tuab-walled ncaj seam welded kav, thaum coils yog siv los tsim ncaj seam kuj welded kav los yog submerged arc kauv welded kav. Lub teb chaws muaj peev xwm ntau lawm ntawm 700, 000 t / a kauv welded kav nrog ib txoj kab uas hla ntawm 180mm thiab tau tsim ib txoj kab ntau lawm rau ncaj seam tuab-walled kav nrog ib txoj kab uas hla ntawm 1600mm. Nws tsuas yog ntau tshaj 10 xyoo nyob rau hauv Suav teb uas cov yeeb nkab steel uas ua tau raws li cov kav dej engineering tsim raws li API5L tus qauv tuaj yeem tsim tau.
3. Cov txheej txheem kev cai
Niaj hnub nimno pipeline steel belongs rau low-carbon lossis ultra-low-carbon micro-alloyed steel, uas yog cov khoom siv high-tech thiab cov khoom muaj nqis ntxiv. Kev tsim cov raj xa dej tau yuav luag siv tag nrho cov kev ua tiav thev naus laus zis tshiab hauv thaj chaw metallurgy hauv 20 xyoo dhau los. Txoj kev loj hlob ntawm pipeline engineering yog cov yeeb nkab loj txoj kab uas hla, siab-siab nplua nuj roj tsheb thauj mus los, high-txias thiab corrosive kev pab cuam ib puag ncig, thiab tuab-walled submarine pipelines. Yog li ntawd, niaj hnub pipeline steel yuav tsum muaj lub zog siab, tsis tshua muaj Bauschinger nyhuv, siab toughness thiab tsis kam mus nkig tawg, tsawg vuam cov ntsiab lus thiab zoo weldability, thiab kuj rau HIC thiab H2S corrosion. Lub tswv yim ua kom zoo tshaj plaws yog los txhim kho qhov huv thiab cov qauv sib xws ntawm cov hlau, C Tsawg dua lossis sib npaug rau 0.09 feem pua , S Tsawg dua lossis sib npaug rau 0.005 feem pua , P Tsawg dua lossis sib npaug li 0.01 feem pua, O Tsawg dua lossis sib npaug li 0.002 feem pua, thiab txais yuav microalloying, nqus degassing CaSi, nruam casting txheej txheem Mos txo, multi-theem thermomechanical yob, ing, thiab multi-functional intermittent ceev cov txheej txheem txias. Tsis muaj qhov toughness Performance index rau pipeline steel nyob rau hauv domestic thiab txawv teb chaws pipeline specifications, tsuas yog rau cov kav dej.
1. Cov kev cai tshwj xeeb:
(1) Ntawm qhov ntsuas kub qis tshaj plaws (-5) DWTT Ntau dua lossis sib npaug rau 85 feem pua SA;
(2) Ntawm qhov kub siab tshaj plaws ua haujlwm (-5) Charpy cuam tshuam kev nqus zog Ntau dua lossis sib npaug rau 145J.
Cov txheej txheem txheej txheem ntawm cov raj xa dej feem ntau txais yuav American Petroleum Institute tus qauv APISpec5L, tab sis cov txheej txheem ntawm cov haujlwm tshwj xeeb hauv tsev lossis cov neeg siv tshwj xeeb feem ntau nruj dua li API cov qauv.
2. Muaj cov kev cai nruj rau kev siv tshuab smelting, thiab cov kev nyuaj siab feem ntau tsom rau:
1) Cov ntsiab lus tswj ntawm impurity ntsiab;
2) Kev tswj hwm suav nrog;
3) Cov khoom siv me me tswj.
3. Cov txheej txheem ntau lawm ntawm kab yeeb nkab
Welded steel kav feem ntau muab faib ua peb txheej txheem: hluav taws xob tsis kam vuam (ERW), kauv submerged arc vuam (SS, AW) thiab ncaj seam submerged arc vuam (LSAW). Cov kav dej welded uas tsim los ntawm peb cov txheej txheem no tau ua haujlwm nyob rau hauv daim ntawv thov teb vim lawv cov khoom sib txawv, tsim cov txheej txheem, caliber si, qhov ntau thiab tsawg, thiab cov khoom zoo.
Tianjin Baolai Steel Group Co., Ltd yog ib lub tuam txhab kev lag luam, uas tsom rau cov kav hlau thiab lwm yam khoom siv hlau. Tsim los ntawm 1991, Baolai yog thawj ob peb lub tuam txhab tshwj xeeb uas tsim thiab tsim cov kav dej zoo tib yam thiab tshwj xeeb. Peb tsim API, ASTM, BS, DIN thiab JIS cov qauv cov kav dej nrog galvanizing chaw. Peb lub peev xwm txhua xyoo yog kwv yees li 2,300,000MT hauv ntau qhov tshwj xeeb thiab xa tawm 150,000MT rau thoob plaws ntiaj teb.
Peb tau txais "Top Ten Collective thiab Private Exporters ntawm Tiajin" los ntawm Tiajin Commerce Department,"Top Ten Exporters ntawm Hexi District" los ntawm Tianjin Hexi Commerce Department, "Top 100 Enterprises ntawm Tianjin" thiab "Top 300 International Trade tuam txhab uas muag ntawm Tianjin" los ntawm Tianjin tsoom fwv, thiab cov qhab nia "AAA" los ntawm cov tsev txhab nyiaj.
Sib nrug los ntawm kev ua tus xa khoom ntawm ntau yam ntawm peb cov khoom, Baolai lub hom phiaj txuas ntxiv nws txoj kev cog lus rau cov neeg siv khoom los ntawm kev txhim kho nws cov kev pabcuam thiab ntxiv cov chaw tshiab. Ib pab neeg mob siab rau yog lub luag haujlwm los muab kev txhawb nqa kev cob qhia txhawm rau qhia txog kev siv cov hlau kom zoo thiab pab cov neeg siv khoom siv cov khoom kom zoo tshaj plaws.
Thov koj xav xa tuaj rau peb nug yog tias koj xav tau ib yam ntawm peb cov khoom.
