Tianjin Yuantai Derun Group JCOE Φ1420 lojlsaw yeeb nkabchav tsev tau muab tso rau hauv kev ua haujlwm los sau qhov sib txawv hauv kev lag luam Tianjin
JCOE yog ib lub tshuab ua yeeb nkab rau kev tsim cov yeeb nkab hlau loj uas muaj phab ntsa tuab, raws li cov txheej txheem tsim khoom siv ob sab hauv qab dej vuam, qhov twg cov khoom raug milled, pre-bent, bent, seamed, internally welded, externally welded, straightened, thiab flat-ended hauv ntau cov txheej txheem. Cov txheej txheem tsim khoom tuaj yeem faib ua N + 1 kauj ruam (N yog tus lej zoo), nrog rau lub phaj hlau raug pub thiab khoov transversely hauv cov kauj ruam teeb tsa kom ua tiav CNC progressive JCO forming. Lub phaj hlau nkag mus rau hauv lub tshuab tsim khoom hauv qhov kev taw qhia transverse, thiab raug tsav los ntawm lub laub pub mov kom ua tiav thawj theem ntawm N / 2 kauj ruam ntawm ntau kauj ruam khoov kom ua tiav "J" tsim ntawm thawj ib nrab ntawm lub phaj hlau; theem thib ob ua rau "J" tsim phaj hlau pub mov sai transverse mus rau qhov chaw transverse Specified, los ntawm lwm qhov kawg ntawm lub phaj hlau tsis tau tsim rau lwm N / 2 kauj ruam ntawm ntau kauj ruam khoov, kom ua tiav ib nrab thib ob ntawm lub phaj hlau tsim, kom ua tiav "C" tsim; Thaum kawg, qhov qis dua ntawm "C" yeeb nkab billet khoov ib zaug kom ua tiav "Txhua kauj ruam ntawm kev nias yog raws li lub hauv paus ntsiab lus ntawm peb-taw tes khoov.
LSAW yeeb nkab hlauua lub luag haujlwm tseem ceeb hauv kev lag luam lojlsaw kab yeeb nkabtej yaam num, dej thiab roj xa mus rau lwm qhov chaw, kev tsim kho hauv nroog, kev tsim kho choj, kev tsim kho hauv nroog thiab kev tsim kho hauv nroog. Nyob rau xyoo tas los no, ua ib hom tshiab ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, lub tsev qauv hlau tau raug hu ua "tsev ntsuab" ntawm lub xyoo pua 21st. Hauv ntau thiab ntau lub tsev siab thiab ultra-siab tsim qauv kom muab qhov tseem ceeb rau kev siv cov hlau lossis hlau-pob zeb qauv system, cov tsev loj-span nquag siv qhov chaw grid qauv, peb-dimensional truss qauv, cable membrane qauv thiab pre-stressed structural system, cov no yog cov yeeb nkab hlau hauv kev tsim kho ntawm ntau daim ntawv thov scenarios, thiab loj-txoj kab uas hla, ultra-tuab-walled steel yeeb nkab thov kuj tau nce ntau heev.Qhov tseeb, lubCov kav dej lsaw thiab hsawtsim los ntawm Yuantai Derun Steel Pipe Manufacturing Group yog dav siv.Raws li ib tug high-zoolsaw yeeb nkab chaw tsim khoomnyob rau hauv Suav teb, Yuantai Derun yog koom nrog nyob rau hauv cov khoom ntawm cov kav dej hlau rau ntau yam loj projects.
Tsis ntev los no, Tianjin Yuantai Derun Steel Pipe Manufacturing Group tau dhau daim ntawv pov thawj ntsig txogAPI 5L LSAW Pipeline, thiab yuav siv ntau dua hauv ntau qhov chaw yav tom ntej. Cov khoom tseem ceeb suav nroglsaw carbon steel yeeb nkab, lsaw steel yeeb nkab loj txoj kab uas hla, thiablsaw welded steel yeeb nkab.
Lub JCOEΦ1420 chav ntawm Tianjin Yuantai Derun Steel Pipe Manufacturing Group tuaj yeem tsim cov lus qhia tshwj xeeb txij li Φ355.6mm txog Φ1420mm hauv txoj kab uas hla thiab txog li 50mm hauv phab ntsa tuab, uas yuav ua kom tiav qhov sib txawv hauv kev lag luam Tianjin rau cov khoom zoo li no thaum nws raug tso rau hauv kev ua haujlwm thiab tuaj yeem ua kom lub sijhawm ua tiav rau kev txiav txim siab loj, ultra-tuab-walled structural pipes thiab rectangular. Ob-sided submerged arc welding loj longitudinal welded yeeb nkab tuaj yeem siv ncaj qha rau roj thiab roj kis, JCOE yeeb nkab steel tau siv dav hauv lub tebchaws "West-East gas kis" project, thaum ua ib lub yeeb nkab hlau tuaj yeem siv rau kev tsim kho ntawm ultra-high-rise steel qauv, ntxiv rau kev siv "round rau square" txheej txheem tuaj yeem ua tiav rau hauv oversized txoj kab uas hla Tsis tas li ntawd, "round rau square" txheej txheem tuaj yeem ua tiav rau hauv oversized, ultra-tuab-walled rectangular steel yeeb nkab, uas tuaj yeem siv rau hauv cov chaw lom zem loj thiab cov tshuab hnyav thiab cov khoom siv tsim khoom.
