High zaus welded yeeb nkab: qhov kev xaiv zoo tshaj plaws rau kev lag luam niaj hnub
Nyob rau hauv txoj kev loj hlob sai ntawm kev lag luam niaj hnub no, high-frequency welded steel yeeb nkab plays lub luag haujlwm tseem ceeb hauv ntau qhov chaw nrog nws qhov tshwj xeeb zoo. Niaj hnub no, peb yuav qhia koj txog daim ntawv thov dav ntawm Huayang steel yeeb nkab kev lag luam nyob rau hauv lub tshav pob ntawm high-frequency welded steel kav.
High-frequency welded steel yeeb nkab muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev lag luam thiab kev tiv thaiv ib puag ncig. Nws cov cuab yeej siv vuam tshuab ua kom muaj kev ruaj ntseg, tsis tshua muaj nqi thiab kev ua haujlwm siab, uas ua rau muaj kev sib tw zoo hauv kev ua lag luam thiab dhau los ua qhov kev xaiv zoo tshaj plaws rau kev thauj mus los ua kua, roj tsheb thauj mus los thiab kev txhawb nqa.
Huayang steel yeeb nkab tau tsim tsis tu ncua nyob rau hauv kaum xyoo dhau los, thiab cov kab ntau zaus vuam ntau lawm tau nce los ntawm 3 mus rau 14. Tam sim no, steel kav nrog diameters ntawm 76mm mus rau 630mm thiab thicknesses ntawm 2.5mm mus rau 18mm yuav ua tau, ntawm cov kav hlau uas muaj txoj kab uas hla ntawm 76 hli thiab 89 hli tuaj yeem yog 8 hli tuab thiab qhov ntev tshaj plaws tuaj yeem ncav cuag 13 meters.
Cov khoom ua tau raws li cov qauv hauv tebchaws xws li GB/T3091 2018, GB/T30063 2013 thiab GB/T9711, nrog rau cov qauv thoob ntiaj teb xws li API 2B thiab API PSL1/PSL2. Cov kab ntau lawm tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ntau yam khoom siv los ntawm Q235B txog Q420D, thiab L245 txog L450M.
Nyob rau tib lub sijhawm, Huayang muaj cov cuab yeej tsim khoom thiab cov txheej txheem tshuaj xyuas nruj heev. Hauv 2019, online ultrasonic flaw detection cov cuab yeej tau ntxiv los txhim kho kev tshawb pom qhov tseeb ntawm cov kav hlau. Nyob rau xyoo 2023, lub tshuab vuam ntau zaus thiab vuam seam intermediate-frequency annealing cov cuab yeej tau hloov kho kom ua tau raws li cov kev cai nruj ntawm API 5L pipeline.
Huayang steel yeeb nkab ib txwm ua raws li qhov tsis tu ncua ntawm kev ua tau zoo, thiab muab cov neeg siv khoom txaus siab rau cov khoom siv high-frequency welded steel yeeb nkab khoom nrog cov thev naus laus zis zoo, txhim khu kev qha zoo thiab cov kev pabcuam zoo heev.
