| Lub elongation (A5) | Ntau dua los yog sib npaug rau 20% |
| Ceev | 7.75 g / cm³ |
3. Cov yam ntxwv ntawm Galvanized Txheej
• Zinc Txheej Ceeb hnyav:Feem ntau ntau dua lossis sib npaug ntawm 70 μm (kwv yees li 500 g / m²), nws yog txawm tias yuav tsum muaj ntau dua lossis sib npaug nrog txhim kho kom ruaj khov.
• Anti - corrosion tshuab:Lub zinc txheej tiv thaiv lub hauv paus steel yeeb nkab los ntawm lub hauv paus ntsiab lus ntawm kev coj ua ntawm kev coj ua, txuas ntxiv haum rau damp lossis corrosive ib puag ncig.
III. Qhov loj me thiab specifications
| Chaw ua uas tsis tau haus | Qho deb |
| Txheej hauv lub taub | 1/2 "{- 12" (21.3-323.9 hli) |
| Lub Phab Ntsa Thickness | 0.8-10.0 HLI |
| Qho ntev | 1-12 m (customizable) |
| Qhov kawg kev kho mob | Xov, grooves, qhov ncauj tiaj lossis tiv thaiv |
IV. Kev tsim khoom txheej txheem thiab cov yam ntxwv kev ua haujlwm
1. Hauv Pause Ntau Lawm
Lub raj Roor yog tsim tau siv siab - zaus ua haujlwm tiv thaiv vuam (ERW) los xyuas kom qhov kev sib txawv ntawm Weld Seam.
2. Galvanizing txheej txheem
- Kub - dip galvanizing: cov kav hlau steel yog raus hauv Molten Zinc (txog 450 degree) los ua cov txheej txheem metallurgical.
- Post - Kev Kho Mob: Nws tuaj yeem muab cov tshuab hluav taws xob epoxy polyester ", uas tau zoo dua anti- corrosion kev ua haujlwm thaum siv rau roj pipelines.
3. Kev Soj Ntsuam Zoo
Xws li cov nplaum (GB / T 9286), kev tsis kam (ntau dua lossis sib npaug ntawm 70 kg.
V. Cov Ntawv Thov
•Kev Tiv Thaiv Hluav Taws:Hluav Taws Dej Muab Khoom Siv Hluav Taws Xob (ua haujlwm siab tsawg dua lossis sib npaug rau 1.6 MPa), haum- Rose / av vaj tse.
• Kev Kis Roj:Nroog Incipeline cov twj siv hluav taws xob (xws li cov Hong Kong Roj thiab Tuam Tshoj National Petroration), Galvanized Txheej dua lossis sib npaug rau 500g / m².
• Tsev qauv:Tsawg - Kev Tiv Thaiv Kev Nyab Xeeb Tsis Siv, Cov Qauv Hlau Txhawb, System Scaffolding System.
• Kev Tsim Dav:HVAC cov tshuab, cov dej num ntawm cov dej tseem ceeb thiab tsawg - siab ntsuas siab xa hluav taws xob pipeline tes hauj lwm.
VI. Cov ntawv pov thawj zoo thiab ua raws li cov qauv
Daim Ntawv Pov Thawj CE:Ua raws li EU cov khoom lag luam hauv tsev kev cai (CPR, tsis muaj 305/2011), thiab yuav tsum xeem dhau qhov kev ua yeeb yam xws li kev sib khi ua tau zoo, kav ntev, thiab kev pheej hmoo siab.
Cov Qauv Sib Koom Thoob Ntiaj Teb:
- ASTM A53 / A500 (American Txheem)
- BS 1387 (Tus Qauv Askiv)
- JIS 3444 (Japanese txheem).
lub ntsiab
En 10255 Galvanized Steel kav tau dhau los ua cov khoom tseem ceeb rau kev tsim kho thiab kev thauj mus los weldability, xov compatient thiab siab {corrosion kev ua tau zoo. Nws cov qauv tsim qauv (xws li nruab nrab / hnyav {{3} Kev tiv thaiv txheej txheem (galvanizing + txheej) tau raws li qhov xav tau ntawm kev tiv thaiv hluav taws thiab roj. Cov khoom siv hluav taws xob loj yog paub tab, tshwj xeeb tshaj yog cov khoom lag luam Suav, uas muaj peev xwm tsim tau, ua rau lawv tsim nyog tau txais kev ua tau zoo nyob rau hauv loj} nplai incrastrastructure tej yaam zis.
