Tsab ntawv xov xwm no tshawb txog cov khoom siv thiab cov lus qhia tshwj xeeb ntawm cov raj hlau profile, qhia txog lawv cov yam ntxwv tseem ceeb, muab cov lus qhia txog tshuaj lom neeg muaj pes tsawg leeg, thiab nthuav qhia cov khoom siv kho tshuab. Tsis tas li ntawd, nws tham txog cov qib steel tshwj xeeb, thaj chaw thov, thiab lwm cov qib ua tau zoo rau cov ntsiab lus tseem ceeb ntawm kev tsim kho niaj hnub no.
Khoom siv thiab Specification
Profile steel raj feem ntau yog ua los ntawm cov pa roj carbon zoo lossis hlau alloy. Kev xaiv ntawm cov khoom yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov thiab cov khoom tsim nyog xws li lub zog, durability, thiab corrosion kuj. Cov raj no muaj nyob rau hauv ntau hom duab thiab ntau thiab tsawg, suav nrog square, rectangular, ncig, thiab elliptical cross-sections.
Cov kev qhia tshwj xeeb ntawm cov yeeb nkab steel feem ntau sib txawv nyob ntawm cov qauv tsim thiab kev siv. Cov kev qhia tshwj xeeb muaj xws li sab nraud txoj kab uas hla (OD), thickness, ntev, thiab kam rau ua. Cov kev ntsuas no xyuas kom meej tias cov raj yog tsim nrog precision thiab ua tau raws li qhov xav tau qhov tseeb.
Ntsiab nta
Profile steel tubes muaj cov txheej txheem tseem ceeb uas ua rau lawv muaj koob meej hauv kev tsim kho kev lag luam:
Lub zog: Cov raj no paub txog lawv qhov zoo tshaj plaws lub zog-rau-hnyav piv, muab cov qauv kev ncaj ncees hauv ntau yam kev siv.
Yooj yim: Profile steel tubes tuaj yeem yooj yim khoov thiab zoo li tus yam tsis muaj kev cuam tshuam rau lawv cov qauv kev ncaj ncees, tso cai rau kev tsim qauv tsim.
Corrosion Resistance: Thaum siv cov hlau tshwj xeeb, cov raj hlau profile muaj qhov tshwj xeeb corrosion tsis kam, ua rau lawv haum rau sab nraum zoov thiab corrosive ib puag ncig.
Yooj yim ntawm kev sib txuas: Vim lawv cov qauv tsim, cov raj no tau yooj yim txuas nrog ntau yam kev sib koom ua ke xws li vuam, bolting, lossis clamping.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm cov yeeb nkab steel profile tuaj yeem sib txawv nyob ntawm seb cov khoom xav tau thiab cov khoom xaiv. Cov lus hauv qab no nthuav tawm cov tshuaj muaj pes tsawg leeg rau carbon steel profile tubes:
| Element | Kev sib xyaw (%) |
| Cov pa roj carbon (C) | 0.20% |
| Silicon (Si) | 0.30% |
| Manganese (Mn) | 1.50% |
| Phosphorus (P) | 0.040% |
| Sulfur (S) | 0.050% |
Mechanical Properties
Profile steel tubes nthuav tawm tshwj xeeb cov khoom siv kho tshuab, ua rau lawv tsim nyog rau ntau hom kev siv. Cov lus hauv qab no nthuav tawm qee yam khoom siv hluav taws xob ntawm cov hlau profile:
| Khoom | Tus nqi |
| Qhov kawg Tensile Strength (MPa) | 500 - 700 |
| Yield zog (MPa) | 300 - 400 |
| Elongation (%) | 20 - 30 |
| Hardness (HB) | 150 - 180 |
Steel Qib thiab Daim Ntawv Thov
Profile steel tubes muaj nyob rau hauv ntau qib steel, txhua qhov muab cov khoom tshwj xeeb thiab kev siv tau. Qee cov qib steel siv rau cov hlau profile muaj xws li:
Qib A: Haum rau kev siv dav dav xws li kev tsim cov thav duab, laj kab, thiab tes tuav.
Qib B: Tsim los rau cov qauv siv uas yuav tsum tau muaj zog ntxiv thiab muaj peev xwm thauj khoom xws li kev tsim kho choj, ncej teeb, thiab cov yees.
Qib C: Muaj kev txhim kho corrosion kuj, ua rau nws zoo tagnrho rau kev siv sab nraum zoov xws li cov khoom siv ua liaj ua teb, scaffolding, thiab cov qauv kev txhawb nqa hauv thaj chaw ntug dej hiav txwv.
