1. Dab tsi yog ob qho txheej txheem loj tsim rau L360 steel yeeb nkab, thiab dab tsi yog lawv qhov sib txawv?
L360 steel yeeb nkab feem ntau yog tsim siv ob txoj kev ua tiav: seamless thiab welded. Seamless steel yeeb nkab yog tsim los ntawm perforating cov khoom siv hlau billet thiab ces dov steel billet thiab ces dov, kos duab, thiab lwm yam txheej txheem. Nws nta tsis muaj Weld Seams, ib qho kev sib tw weld, ib seem}}}}} muaj peev xwm tsawg thiab nws tus nqi yog qhov siab. Welded steel yeeb nkab, ntawm qhov tod tes, yog tsim los ntawm cov kav hlau siv khoom siv, thiab tom qab ntawd vuam cov leeg ua ke siv ntau txoj kev vuam. Cov qauv no muaj kev ua haujlwm siab, tus nqi qis, thiab lub peev xwm los tsim cov kav dej loj, ua rau nws cov pipeStream rau niaj hnub no. Qhov tseem ceeb ntawm ob txheej txheem lus dag nyob rau hauv lub xub ntiag nyob rau hauv lub xub ntiag ntawm weld seam, uas yog vim li cas Welded Steel kav yuav tsum tau muaj ntxiv, nruj tsis muaj kev soj ntsuam.
2. Dab tsi yog cov kev sib tw v hlau siv los tsim L360 Welded Steel Yeeb Nkab?
Lub ntsiab, txuag txoj kev vuam rau raug tsim L360 Welded Steel Yeeb yog submerged arc vuam. Ua raws li cov txheej txheem tsim, ncaj qha zeem subgerged arc vuam (lsaw) thiab muab kauv tau faib ua cov txheej txheem. LSAW tau siv txoj kev ua qhev lossis Jocke tsim txoj kev, ua rau muaj kev sib sib zog nqus thiab zoo nkauj}} {}}}}}}}}}}}}}}}}}}}}}}}}}} kub ripelines. Muab Kauv Pom Kev Muab KAUV, tso cai rau cov kav dej ntawm ntau qhov strips los ntawm tib strip qhov dav. Qhov no muaj siab heev, tab sis nws tseem tuaj yeem ua rau muaj kev ntxhov siab ntev dua thiab kev ntxhov siab ntev dua. High - zaus Kuj siv vuam (HFRI) kuj yog siv rau cov hlab pas me me. Thaum siv tau zoo heev, nws yog feem ntau siv nyob rau hauv cov ntawv thov siab qis dua. Cov kev ntsuam xyuas cov hlau no xav tau kev sim online lossis ua txhaum cai
3. Lub luag haujlwm ua kom sov ua si hauv L360 cov yeeb nkab steel ua haujlwm ntau lawm?
Kev kho cua sov yog cov kauj ruam tseem ceeb hauv kev tswj hwm ntawm microstructure kawg thiab cov khoom siv tshuab ntawm L360 steel yeeb nkab. Rau cov kav dej uas tsim cov tswj hwm dov thiab tswj cov txheej txheem txias, lawv cov khoom siv txias tau ua tiav, feem ntau tshem tawm qhov xav tau kev kho cua sov ntxiv. Txawm li cas los xij, cov kav hlau hlau tsim cov txheej txheem siv tau cov txheej txheem yuav xav tau ua ntu zus thiab ua kom muaj cov pa taws ua kom zoo nkauj thiab ua kom muaj cov khoom siv hluav taws xob thiab txhim kho kev nruj. Tsis tas li ntawd, txias {{- Ua haujlwm Steel kav yuav tshem tawm cov kev ntxhov siab steel tsis txaus siab los ntawm kev ua haujlwm txias thiab restore yas thiab tawv. Txhua qhov kev kho cua kub kom zoo yog qhov tseem ceeb heev rau kev ua kom txhua L360 steel yeeb muaj cov khoom siv sib txuam thiab ua tau raws li cov qauv.
4. Dab tsi yog qhov nthuav dav txias hauv welded steel yeeb nkab tsim, thiab nws lub hom phiaj yog dab tsi?
Txias nthuav dav yog cov kauj ruam kawg hauv LSAWB yeeb nkab ntau lawm kab. Thaum lub sijhawm tus txheej txheem no, Welded steel yeeb nkab tau noj rau hauv kev nthuav dav. Ib txheej ntawm cov tuag nyob rau hauv qhov kev nthuav dav nthuav tawm cov yeeb nkab los ntawm ob qho kawg mus rau qhov chaw, ua rau muaj cov yeeb nkab me ntsis ntawm tag nrho cov yeeb nkab. Cov txheej txheem no ua rau peb lub hom phiaj tseem ceeb: ua ntej, nws tso cai rau cov kab ntsig thiab kev sib tw ua kom muaj txiaj ntsig, lub rooj sib tham hlua khau kom muaj. Thib ob, cov txheej txheem nthuav dav ua rau muaj cov khaub ncaws yas deform, ib nrab tso tawm thiab sib luag ntawm kev tsim khoom thiab txhim kho qhov seem ruaj khov. Thaum kawg, nws tseem ua haujlwm ua kev sim ntawm cov yeeb nkab steel hlau nws tus kheej; Ib qho chaw twg nrog kev tsis txaus siab loj yuav ua fracture thaum nthuav dav, yog li raug kuaj pom.
5. Dab tsi yog cov tseem ceeb technology rau kev tsim khoom tshiab niaj hnub ntawm high- Lub zog Pipeline cov hlau xws li L360?
Cov ntsiab lus thev naus laus zis rau cov khoom siv niaj hnub ntawm high - lub zog, siab} Tus qauv dov thiab tswj txias "txheej txheem. Qhov no yog ib qho tshwj xeeb tswj thermomechanical txheej txheem. Nws yuav tsum muaj cov khoos phis tawm ntawm lub tshuab hluav taws xob ntawm lub npov cua sov, tus nqi ntawm qhov kub thiab txias, thiab txias tus nqi tom qab dov. Tsawg - kub "} tsis - recrystallization cheeb tsam dov" tsis kam lees qhov qub ntawm austenite nplej. Tom qab, "nrawm nrawm" tam sim ntawd tom qab dov suppresses tsim ntawm coarse ferrite thiab txhawb nqa kev tsim cov qauv ntawm cov qauv zoo xws li nplua acicular. TMCP cov txheej txheem tuaj yeem ua tiav kev sib xyaw ua ke ntawm lub zog siab, muaj zog heev thiab zoo nkauj weldability tsis muaj kev vam meej ntau yam, uas yog ib qho kev sib tw loj heev hauv metallurgical.
