Q1: Lub tsev tsim S355J30h tus qauv dab tsi siv rau?
S3555j-}}}} REAV LATHice shells, choj trusses, thiab nroj tsuag. Nws lub zog siab thiab zoo heev veldability ua nws txoj kev xaiv zoo tshaj plaws rau ntev- spanish terminal vov tsev txhawb nqa. Nws cov tawv muaj zog ua rau lub zog tsis nco qab txog kev tsim tawm seismic. Nws kuj yog siv rau hauv vaj kab hlaule phab ntsa thaiv thiab cov qauv hlau zoo nkauj. Qhov piv txwv ib txwm yog cov raj steele truss ntawm London Olympic Chaw Ntau, uas nws lub teeb tsim qauv tseem txo lub hauv paus ntim khoom.
Q2: Vim li cas yog S3555555555555555 ... cov yeeb nkab coj tsim rau choj engineering?
Hauv cov choj, S355J30HJ 2H hlau kav yog feem ntau siv rau cov kab teeb loj, cam tav, thiab cov qauv txhawb nqa. Nws 355 mpa tawm los lub zog tuaj yeem tiv taus cov tsheb thauj khoom zoo. Nws qhov qis - kub nrawm (cuam tshuam rau lub zog loj dua lossis sib luag rau 27 J ntawm -20 degree) kom nws resistays brittle fracture nyob rau hauv cov cheeb tsam txias. Tsis tas li ntawd, nws cov huab cua tsis dhau surpiveres uas yog cov carbon hlau, txo cov tha xim thiab cov nqi kho. Piv txwv li, ib qib hluav taws xob zoo sib xws hauv kev txhawb nqa hluav taws xob ntawm Denmark txoj hlua khi loj. Hollow tsim ntawm cov yeeb nkab steel kuj tseem txo nws qhov hnyav, ua rau nws thauj khoom thiab nruab.
Q3: Cov ntawv thov ntawm S355J30h steel yeeb nkab hauv lub zog sector?
In the energy sector, S355J2H steel pipe is used in wind turbine towers, oil platform supports, and transmission towers. Cua Turbine yees yuav tsum quav zog hloov cua, ua kom muaj kev qaug zog kev ua tau zoo; Roj platform txhawb nqa yuav tsum tau tiv taus dej hiav txwv corrosion thiab feem ntau yuav tsum tau txuas ntxiv lossis tshuaj tsuag. Tus qib steel no kuj tau txhawb nqa ntawm -}}} Cov txheej txheem hauv hiav txwv thiab roj platform modules. Txuas ntxiv, nws tus nqi - Qhov ua tau zoo yog qhov zoo dua rau qhov siab dua - scale nplai zog kev tsim kho.
Q4: Yuav ua li cas S35J30H ... Hlau Yeeb tau xaiv rau kev siv tshuab?
Thaum xaiv S3555j2H steel yeeb nkab rau kev siv tshuab (xws li crane caj npab thiab cov thav duab excav), nws yog qhov tseem ceeb kom ntsuas seb nws phab ntsa tuab thiab bendant tsis kam. Nws cov peev txheej lub zog sib piv (reh / rm) kom nws tawm tsam cov khoom siv ntau yam nyob rau hauv cov khoom siv tsis sib haum. Feem ntau, txias dabtsi yog tsim lossis siv vuam siv, xav tau cov tshuaj ntsuam muaj tseeb (fea) kom pom kev ntxhov siab. Piv txwv li, Sany Hnyav Kev Kub Hluav Taws Xob Cov Tsheb Hluav Taws Xob Cov Khoom Siv Zoo Tshaj Plaws rau qhov sib npaug phaus thiab lub zog. Hnav {{6- Cov chaw tiv taus kuj yuav xav tau cov kab nrog siab- hadness cov ntaub ntawv.
Q5: Muaj peev xwm S355j2h S355J2H siv tau hauv cryogenic siab cov hlab ntsha?
Txawm hais tias S355jT2H tsis yog ib qho kev xav txog ntshauv steel, nws tuaj yeem siv hauv qhov ntsuas qis thiab qis}}}) tom qab kev tsim nyog ntxiv cuam tshuam. Txawm li cas los xij, nws cov pa roj carbon ntau (cet) yuav xav kom post-Weld kev nyuaj siab pab txhawb kev pab cuam. Rau cov ntawv thov cryogenic (xws li LNG cia tso tsheb hlau luam), S355Nl lossis Austenitic Stainless Hlau yog qhov pom zoo. Yog tias siv, tus qauv tsim thiab kev sim yuav tsum nruj me ntsis ua raws li EN 13480 siab rau cov txheej txheem.
