Tau thiab Lub Hom Phiaj
- Txheem Npe: Txheem Qhov tshwj xeeb rau cov khaub thuas - mive welred welded carbon hlau hollow qauv txheej txheem (hss)
- Tsim los ntawm: Astm International (SubcomticeeA01.09Ntawm cov hlau qauv)
- Thawj siv: Cov ntawv thov txheej txheem xav tau kom muaj zog siab, kev thev taus lub siab, thiab weldability.
- Cov Ntsiab Lus Tseem Ceeb Tshaj A500:
Siab zog - rau - qhov hnyav.
Txhim kho qhov seem.
Zoo dua Weldability thiab ductility rau seismic thiab dynamic chaw thau khoom.

| Silicon (si), max | Rau Kev Ntsuam Xyuas Cua Sov: 0.04% |
| Rau Cov Khoom Ntsuam Xyuas: 0.07% | |
- Sau ntawv:For each reduction of 0.01 percentage point below the specified maximum for carbon, an increase of 0.06 percentage point above the specified maximum for manganese is permitted, up to a maximum of 1.50% by heat analysis and 1.60% by product analysis.
Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | ASTM A1085 tseev kom muaj |
|---|---|
| Yield zog (min) | 50 Ksi (345 MPa) - 70 KSI (485 MPa) |
| Tensile lub zog (min) | 65 KSI (450 MPA) |
| Elongation (min,%) | 21% (nyob ntawm phab ntsa tuab) |
- Sau ntawv:Qhov tsawg kawg nkaus uas muaj nuj nqis elongation tau sau tseg tsuas yog siv rau kev sim ua ntej xa khoom ntawm tubing.
Cov txheej txheem tsim khoom
Txias Txoj Kev & Vuam
- Kev sib sau: Tiaj tus hlau yog yob - tsim rau hauv puag ncig, xwmfab, lossis duab plaub.
- Vuam: High {{- zaus siv hluav taws xob vuam (ERW) lossis laser vuam ua kom ua tiav ibseamless, siab - lub zog sib koom ua ke.
- Sizing & shaping: Cold {- Ua haujlwm kom ua tiav kom ua tiav kev tiv thaiv nruj (± 0.5% ntawm qhov ntev).
Kev cuam tshuam cov tawv (charpy v - Itch)
Yuav tsum tau txhua tus hss kom tau raws li Charpy v {{leb ntawm 40 Degree F. Qhov no ua rau cov qauv zoo li nkees thiab qis- qhov ntsuas kub.
Cov Ntawv Thov
High -} Rose vaj tse:Cov lej sib zog nrog cov nqi siab dua.
Txuas hniav:Txhim kho kev qaug zog tsis kam.
Seismic zones:Zoo zog nqus lub zog thaum lub ntiaj teb.
Tus kws kos duab nthuav tawm cov hlau:Kev thov kom zoo nkauj rau kev ua kom zoo nkauj nrog cov qauv kev ntseeg.
