Cov Lus Nug Feem Ntau:

Q: Qhov txawv ntawm EN 10219 S355JRH thiab EN 10210 S355JRH yog dab tsi?
A: EN 10219 yog rau cov seem hollow uas tau vuam txias (kev vuam thiab kev tsim yog ua tiav ntawm chav tsev kub). EN 10210 yog rau cov seem hollow kub tiav (seamless lossis welded thiab tom qab ntawd kho cua sov). Rau cov kav dej LSAW, EN 10219 yog tus qauv tseem ceeb. EN 10210 cov seem kub tiav feem ntau yog seamless lossis ERW. Ob qho tib si muaj cov khoom siv kho tshuab zoo sib xws.

Q: Koj puas muab tau S355J2H (cuam tshuam ntawm -20 ° C) es tsis txhob S355JRH?
A: Yog. S355J2H muaj thaum thov rau cov ntawv thov kub qis xws li cov qauv hauv hiav txwv lossis arctic. Cov tshuaj lom neeg sib xyaw zoo sib xws tab sis muaj cov kev txwv nruj dua thiab lav qhov cuam tshuam Charpy ntawm -20 ° C (yam tsawg kawg nkaus 27J). Muaj tus nqi ntxiv.

Q: Koj puas muab CE cim rau EN 10219 cov kav dej?
A: Yog. Womic Steel muaj daim ntawv pov thawj Factory Production Control (FPC) raws li EN 10219. Peb muab CE cim nrog Daim Ntawv Tshaj Tawm Kev Ua Haujlwm (DoP) rau cov kav dej muag rau hauv European Economic Area (EEA). Qhov no ua kom ntseeg tau tias kev tshem tawm kev lis kev cai thiab kev lees txais qhov project zoo.

Q: Qhov ntev tshaj plaws rau kev kub-dip galvanizing yog dab tsi?
A: Peb tus khub galvanizing muaj qhov ntev ntawm 13.5m. Yog li ntawd, cov kav dej txog li 12.5m tuaj yeem raug raus thiab galvanized tag nrho. Rau cov kav dej ntev dua, peb tuaj yeem npaj galvanizing seem lossis siv lwm txoj hauv kev (zinc-nplua nuj epoxy). Thov hu rau peb rau qhov xav tau ntev tshwj xeeb.

Q: Koj puas tuaj yeem sib tsoo weld flush rau cov hlau architectural uas raug nthuav tawm?
A: Yog. Rau cov kav dej uas pom tau (piv txwv li, cov kem hauv tshav dav hlau, cov choj arches), peb tuaj yeem sib tsoo lub hau SAW weld kom sib npaug nrog lub cev yeeb nkab. Qhov no yog ib qho kev ua haujlwm ntxiv thiab ntxiv tus nqi thiab lub sijhawm ua khoom (kwv yees li + 15%). Peb xav kom qhia meej qhov yuav tsum tau ua no thaum lub sijhawm xaj.

Q: Cov txheej txheem twg yog qhov pom zoo rau cov hlau ua vaj tse sab nraum zoov?
A: Rau sab nraum zoov, txheej primer (zinc-nplua nuj epoxy, 60-80 microns) yog tus qauv rau kev tiv thaiv ib ntus thaum lub sijhawm tsim kho. Rau kev tiv thaiv tas mus li yam tsis tas yuav pleev xim, kub-dip galvanizing (85-100 microns) yog qhov zoo tshaj plaws rau cov chaw ua phem. Rau kev siv sab hauv tsev, qhov chaw oiled lossis tsawg kawg nkaus primer txaus.

Q: Lub sijhawm ua cov yeeb nkab S355JRH LSAW feem ntau yog dab tsi?
A: Lub sijhawm ua tus qauv: 30-45 hnub rau JCOE/UOE qhov ntau thiab tsawg. Rau cov phaj dov phab ntsa hnyav (> 50mm): 45-60 hnub. Rau welded thiab av tiav: ntxiv 2 lub lis piam. Rau kub-dip galvanizing: ntxiv 1-2 lub lis piam nyob ntawm lub sijhawm da dej.

Tus Qauv & Qib:EN 10219 S355JRH (nrog rau kev cuam tshuam Charpy ntxiv ntawm 0 ° C thiab kev sib tsoo vuam rau cov hlau uas raug nthuav tawm)
Qhov Loj & Qhov Ntau:

● OD 508mm (20″) × WT 16.0mm – 4,500 meters (kwv yees li 830 tons) tsim los ntawm UOE txheej txheem

● OD 610mm (24″) × WT 20.0mm – 3,200 meters (kwv yees li 930 tons) tsim los ntawm UOE txheej txheem

● OD 813mm (32″) × WT 25.0mm – 1,800 meters (kwv yees li 880 tons) tsim los ntawm JCOE txheej txheem

● OD 1,016mm (40″) × WT 30.0mm – 1,200 meters (kwv yees li 840 tons) tsim los ntawm cov phaj dov ib leeg
Tag Nrho:10,700 meters (10.7 km) ntawm cov kav dej, kwv yees li 3,480 tons

Cov Lus Qhia:Cov xaus tiaj tiaj nrog chamfer (rau kev vuam taub qab), lub hau vuam av sib npaug rau lub cev yeeb nkab (qhov yuav tsum tau ua kom pom tseeb), txheej primer (zinc-nplua nuj epoxy, 60 microns). Yuav tsum tau kuaj flattening, kev kuaj khoov coj, 100% UT ntawm cov leeg vuam ntxiv rau 10% RT. Kev cuam tshuam Charpy ntawm 0 ° C (yam tsawg kawg nkaus 27J, ua tiav 80-120J). CE cim nrog Daim Ntawv Tshaj Tawm ntawm Kev Ua Tau Zoo. Kev tshuaj xyuas thib peb los ntawm TÜV Rheinland. Txhua lub yeeb nkab xav tau kev ncaj ≤ 0.15% (nruj dua li tus qauv 0.2%).

Daim Ntawv Thov:Chaw Ua Si Al Wakrah (tseem hu ua Al Janoub Stadium), yog ib qho chaw ua si FIFA World Cup 2022. Lub ru tsev muaj cov hlua khi uas muaj lub nplhaib hlau thiab cov trusses radial. Cov kav dej LSAW tau siv rau lub nplhaib tseem ceeb (1,016mm OD) thiab cov truss chords radial (813mm, 610mm, 508mm). Lub ru tsev dav li ntawm 200m hauv txoj kab uas hla thiab npog 42,000 lub rooj zaum.

Cov Kev Sib Tw thiab Kev Dais Teeb Meem:

● Cov hlau uas raug tsim los ntawm kev sib tsoo vuam - qhov yuav tsum tau sib tsoo– Lub ru tsev ntawm lub chaw ua si pom tau los ntawm sab hauv thiab sab nraud. Tus neeg siv khoom xav tau lub hau vuam kom sib tsoo rau lub cev yeeb nkab kom du. Womic ua qhov vuam sib tsoo siv cov tshuab sib tsoo orbital tsis siv neeg ua raws li kev ua tiav tes. Txhua qhov vuam raug tshuaj xyuas rau qhov du (qhov roughness Ra ≤ 6.3μm). Qhov no ntxiv 2 lub lis piam rau kev tsim khoom tab sis ua tiav qhov tiav zoo nkauj xav tau.

● Qhov yuav tsum tau ncaj nraim siab– Lub nplhaib nias yuav tsum tau cov kav dej uas ncaj ≤ 0.15% (tus qauv EN 10219 tso cai 0.2%). Womic siv cov txheej txheem UOE thiab JCOE nrog kev nthuav dav tshuab kom ua tiav qhov ncaj ntawm 0.08-0.12%. Txhua lub kav dej tau ntsuas ntawm lub rooj ncaj (laser alignment). Cov kav dej uas tsis kam rau siab tau ncaj siv lub tshuab hydraulic press.

● Txheej pleev xim rau thaj chaw suab puam– Qatar muaj qhov kub thiab txias siab (txog li 50°C), av noo siab (txog li 85% thaum lub caij ntuj no), thiab xuab zeb hauv huab cua. Cov xim pleev epoxy nplua nuj zinc (60 microns) tau siv rau txhua lub kav dej. Kev txheej txheem dhau qhov kev sim ntsev tsuag (1,000 teev, ASTM B117) nrog tsawg dua 2 hli nkag. Kev kuaj pom hnub so ntawm 2kV. Kev nplaum ntsuas ntawm 8 MPa (tsawg kawg 5 MPa).

● Kev npaj khoom nyuaj thaum lub sijhawm tsim kho FIFA– Kev tsim kho chaw ntau pob muaj lub sijhawm nruj heev (2020-2021). Womic xa cov kav dej hauv 4 qhov kev xa khoom (txhua 800-1,000 tons) dhau 8 lub hlis. Cov kav dej tau xa los ntawm Shanghai mus rau Hamad Port (Doha), tom qab ntawd thauj khoom 45km mus rau qhov chaw ua si. Vim muaj kev txwv COVID-19, Womic cov neeg soj ntsuam tsis tuaj yeem mus ncig. Peb tau npaj kev soj ntsuam deb ntawm cov neeg pom los ntawm kev pub video nyob (TÜV online). Tag nrho 3,480 tons tau txais los ntawm deb.

● Kev cuam tshuam ruaj khov rau qhov kub thiab txias qis– Txawm hais tias Qatar kub heev, hmo ntuj thaum lub caij ntuj no tuaj yeem poob mus rau 10 ° C, thiab lub ru tsev raug nthuav tawm. EN 10219 S355JRH xav tau Charpy cuam tshuam ntawm 0 ° C (27J min). Womic tau txais 80-120J, siab dua qhov yuav tsum tau ua. Cov ntawv qhia kev xeem tau suav nrog hauv pob CE DoP.

●Qhov Tshwm Sim:Al Wakrah Stadium tau qhib rau xyoo 2022 thiab tau tuav rau qhov kev sib tw World Cup. Lub ru tsev hlau tau txais kev qhuas dav dav rau nws txoj kev tsim qauv zoo nkauj. Tus neeg cog lus (tus thawj coj ua hlau hauv Tebchaws Europe) tau tshaj tawm tias tsis muaj qhov tsis zoo ntawm kev vuam thaum lub sijhawm teeb tsa. Tag nrho cov kav dej LSAW haum zoo kawg nkaus ntawm qhov chaw tsis muaj kev kho dua tshiab. Womic Steel tau txais tsab ntawv qhuas los ntawm tus neeg cog lus tseem ceeb rau "qhov tseeb ntawm qhov ntev thiab kev vuam tiav." Lub chaw ntau pob tseem ua haujlwm ua qhov chaw ua kis las thiab kev tshwm sim ntau yam.
