Phau ntawv qhia no yog ib qho kev siv los ua ib qho kev qhia txog kev siv tshuabS460NHcov hlau carbon structural hollow sections (SHS, RHS, thiab CHS) tsim tawm raws liEN 10210tus qauv.
Lus Cim Tseem Ceeb:S460NH yog cov hlau uas muaj zog heev, ua kom zoo li qub. Nws TSIS YOG hlau tsis xeb. Hauv cov chaw muaj xeb lossis dej hiav txwv, feem ntau yuav tsum muaj cov txheej txheem txheej txheem tshaj lij, xws li C5-M epoxy-based system.
1. S460NH Yog Dab Tsi? (Kev Txhais Lub Qib)
S460NH yog tsim los rau cov ntawv thov uas muaj kev thauj khoom ntau qhov twg kev ntseeg siab ntawm cov qauv tsis tuaj yeem sib tham tau. Nws lub npe yog yooj yim:
| Lub Cim | Lub ntsiab lus |
|---|---|
| S | Cov Hlau Ua Vaj Tse |
| 460 | Yam tsawg kawg nkaus Yield zog ntawm460 MPa(ntawm t ≤ 16 hli) |
| N | Normalized (Cov qauv zoo-grain rau kev tawv) |
| H | Tshooj Hollow |
2. Cov Lus Qhia Txog Kev Siv Tshuab (Qhov Ntsuas Zoo)
Rooj 1: Cov Tshuaj Lom Zem (Kev Tshawb Fawb Kub, % max)

3. Kev Tsim Khoom & Kev Vuam: Qhov Zoo ntawm "Kev Tiv Thaiv Kev Distortion"
Ib qho tseem ceeb uas ua rau EN 10210 S460NH kub-ua tiav dhau ntawm cov seem txias yog nws qhov ruaj khov ntawm cov qauv. Los ntawm kev tswj hwm tag nrho lub cev kom zoo li qub, peb tshem tawm cov kev ntxhov siab sab hauv uas feem ntau ua rau "caij nplooj ntoos hlav rov qab" lossis ntswj, kom ntseeg tau tias muaj kev haum siab.
Kev Kawm Txog Cov Ntaub Ntawv: Cov Chaw Tsim Kho Hauv Dej Hiav Txwv
- Cov Haujlwm Choj Offshore:Los ntawm kev hloov cov seem uas tau tsim txias nrog peb cov S460NH uas tau ua kom zoo li qub, cov neeg siv khoom tau ua tiav ib qhoTxo 40% ntawm lub sijhawm kho kom haum, vim tias cov trusses sib dhos zoo kawg nkaus thaum lub sijhawm sib dhos, tshem tawm qhov xav tau kev kho kim heev ntawm qhov chaw.
- Lub hauv paus cua ntawm ntug dej hiav txwv:Hauv kev tsim cov tsho loj ntawm lub tshuab cua turbine thiab kev hloov pauv, kev kam rau siab ntawm cov qauv yog qhov tseem ceeb heev. Peb cov S460NH uas tau ua kom zoo ib yam muab qhov sib xws ntawm qhov ntev uas xav tau rau cov kab vuam hlau tsis siv neeg. Ntxiv mus, thaum cov qauv cua hauv hiav txwv European hloov zuj zus, peb cov S460NH tau nyiam dua S460QL vim nws qhov sib npaug zoo ntawm kev vuam thiab kev tiv taus qaug zog.
Kev Ua Kom Tiav Hauv Kev Vuam Phab Ntsa Hnyav
Tsis tas li ntawm cov qauv choj thiab cua, qhov kev tsim khoom no nthuav dav mus rau txhua yam khoom siv hnyav. Tsis zoo li cov khoom siv cua txias, peb lub voj voog cua sov uas tswj tau qhov kub thiab txias ua rau cov qauv noob sib xyaw ua ke, txo cov kev ntxhov siab sab hauv ntau dua 60%. Qhov no ua kom koj cov pob qij txha uas muaj kev txwv siab tiv taus kev tawg txias thiab kev tawg yooj yim dua.
4. Kev Ceeb Toom Rau Cov Neeg Yuav Khoom B2B: Tsis Txhob Siv S460NH "Cua Dag"
⚠️ CEEB TOOM TXOG KEV TSWJ HWM: Tsis txhob yuav "S460NH" uas ua haujlwm zoo li hlau tsis muaj zog.
Ntau tus neeg muag khoom theej cov ntaub ntawv los ntawm ASTM A106B lossis S235 hlau, uas qhia txog lub zog tsis muaj zog ntawm tsuas yog 240 MPa lossis tsawg dua.Qhov no yuav ua tsis tiav koj qhov kev tshuaj xyuas qauv.
