S355J2tuaj yeem siv rau txhua daim ntawv thov steel qhov twg qhov kev ua haujlwm kub tuaj yeem poob mus rau -20℃lossis qis dua.Nwsyog tus qauv, code-raws li cov khoom siv rau kev tsim kho hauv cheeb tsam huab cua txias.
Ntawm no yog ib daim ntawv teev tag nrho ntawm nws cov kev siv tseem ceeb:
1. Lub Tsev & Kev Tsim Kho
Kev Lag Luam / Kev Lag Luam Kev Lag Luam: Lub Hoobkas tsev, warehouses, khw muag khoom, thiab chaw ua haujlwm hauv cheeb tsam txias (xws li Scandinavia, Canada, Northern USA, Russia).
Ntau-Cov Tsev Dab Neeg: Cov ncej hlau rau cov tsev, tsev so, thiab tsev kho mob.
Tsheb Chaw Nres Tsheb & Tshav Dav Hlau Terminals: Loj, raug steel qauv.
Sports Halls & Arenas: Ntev -span ru tsev.
2. Cov choj thiab kev thauj mus los
Txoj Kev Loj & Kev Tsheb Ciav Hlau: Girders, hla- kab teeb, bracings, thiab parapets.
Footbridges & Cycle Path Bridges.
Overpasses thiab Interchanges.
Lub Suab Barrier Support Structures raws txoj kev loj.
3. Zog & Fais fab Sector
Cua Turbine Ntauwd (tshwj xeeb tshaj yog rau cov dej num onshore hauv huab cua txias).
Fais fab kis ntauwd (pylons) thiab substation qauv.
Txhawb Cov Qauv rau Solar Farms hauv cov cheeb tsam txias.
Pipeline Supports thiab Gantries.
4. Industrial & Heavy Engineering
Crane Runways thiab Txhawb Gantries hauv unheated factories.
Heavy Machinery Frames thiab Bases (piv txwv li, rau cov khoom siv mining ua haujlwm hauv qhov chaw txias).
Silos, Tanks, thiab Conveyor Support Structures.
Offshore Access Platforms (rau cov ntawv thov tsis tshua muaj txiaj ntsig; S355NL yog siv rau thawj cov pob).
5. Kev Sib Txuas Lus & Kev Siv Hluav Taws Xob
Xov tooj cua, TV, thiab kev sib txuas lus Masts.
Teeb pom kev zoo rau txoj kev loj thiab thaj chaw loj.
Txhawb nqa cov qauv rau tsheb ciav hlau Gantries.
6. Agricultural & Tsheb thauj mus los
Ncej rau Hnyav-Lub Tsheb Ua Haujlwm Ua Haujlwm (piv txwv li, sib txuas, tsheb laij teb) siv nyob rau hauv huab cua txias.
Chassis rau Kev Thauj Khoom Tshwj Xeeb thiab Trailers ua haujlwm nyob rau lub caij ntuj no.
Vim li cas thiaj siv cov no? Qhov Tseem Ceeb Tseem Ceeb: Kub
Tag nrho cov ntawv thov no qhia ib qho kev xav tau: tus qauv raug rau sab nraum zoov kub hauv cheeb tsam uas lub caij ntuj no kub tsis tu ncua mus txog -20 degree.
S355J2 muab cov ntaub ntawvmyam tsawg kawg nkaus guaranteed toughness (27J ntawm -20 degree) los tiv thaiv brittle fracture, uas yog ib tug txaus ntshai thaum high-lub zog steel yuav txias heev thiab poob nws ductility.
Dab tsi S355J2 yuav tsum tsis txhob siv rau:
Cov qauv sab hauv tsev hauv huab cua sov (xws li Middle East) - S355JR yog tus nqi ntau dua - siv tau.
Cov ntawv thov uas yuav tsum muaj zog hauv qab -20℃(xws li Arctic offshore platforms) - Siv S355NL (-50 degree) lossis S420ML.
Cov ntawv thov uas xav tau lub zog siab dua (piv txwv li, ntev -span crane girders) - Siv S420M lossis S460Q.
Kev ua haujlwm siab, qaug zog- cov khoom tseem ceeb hauv cov ntu tuab - Xav txog cov qib zoo li S355N kom zoo dua los ntawm - cov khoom tuab.
Sib piv: S355J2 vs. Lwm Qib rau Kev Siv Tshwj Xeeb
| Yog koj tsev... | Hauv qhov kev nyab xeeb no ... | Siv qib no... |
|---|---|---|
| Ib lub tsev khaws khoom hauv Spain | Lub caij ntuj no me me (tsis tshua muaj Frost) | S355 JR |
| Ib lub Hoobkas nyob hauv lub teb chaws Yelemees | Temperate (tsis tu ncua Frost, mus rau -5 degree) | S355J0 |
| Ib tug choj nyob rau hauv Norway | Txias (lub caij ntuj no mus rau -25 degree) | S355J2 |
| Ib tug cua ntauwd nyob rau hauv Sweden | Txias, nrog kev nyab xeeb dua | S355K2 (40J ntawm -20 degree) |
| Ib tsob nroj mining hauv Canada | Txias, nrog tuab welded daim hlau | S355N (normalized, 40J ntawm -20 degree) |
| Ib qhov chaw tshawb fawb Arctic | Qhov txias txias (hauv qab -40 degree) | S355 NL |
Cov ntsiab lus:
S355J2 yog cov hlau ua haujlwm rau cov huab cua txias. Nws siv yog tsav los ntawm thaj chaw thiab huab cua es tsis yog kev lag luam tshwj xeeb. Yog tias koj qhov kev tsim kho yog nyob rau hauv ib cheeb tsam nrog lub caij ntuj no txias thiab cuam tshuam nrog kev ua haujlwm steel, S355J2 yog qhov zoo tshaj plaws, cov khoom siv rau cov qauv tsim thiab kev txhawb nqa. Nws yog lub neej ntawd, kev nyab xeeb, thiab kev xaiv kev lag luam kom ua tau raws li cov cai hauv tsev rau qis- qhov kub thiab txias hauv cheeb tsam txias thoob ntiaj teb.
