Technical ntawm Rectangular Steel Tube
Rau cov txheej txheem engineers, procurement tub ceev xwm, thiab fabricators, xaiv txoj cai rectangular profile yuav tsum tau soj ntsuam qhov tseem ceeb mechanical thiab metallurgical tsis:
-
Qhov zoo ntawm Symmetrical Bending Advantage:Tsis zoo li qhib cov ntaub ntawv (xws li kuv- kab teeb lossis cov kab) uas tuaj yeem sib tw lossis flex raws li lawv cov axis tsis muaj zog, ib lub voj voos hollow faib cov cuab yeej siv tau zoo. Nws muaj kev tiv thaiv siab rau sab nraub qaum thiab torsional (twisting) kev ntxhov siab, ua rau nws zoo tagnrho kem lossis kab rov tav txhawb nqa hauv qhov chaw -frame designs.
-
Txias-Formed (ASTM A500 / EN 10219) vs. Kub-Tiav lawm (EN 10210):Peb muab cov raj duab plaub zoo rau kev tsim qauv sib txawv:
-
Txias-Formed (ASTM A500 Gr. B/C, EN 10219):Ua haujlwm- tawv thaum chav tsev- qhov kub thiab txias ua kom muaj kev lag luam zoo, nruj- ntu kam rau ua nrog lub ntsej muag du.
-
Kub-Tiav lawm (EN 10210 S355J2H):Tsim los yog cua sov-kho ntawm qhov kub thiab txias kom tshem tawm cov kev ntxhov siab ntawm cov khoom seem, muab qhov kev kwv yees siab tshaj plaws nyob rau hauv dynamic seismic lossis cyclic load.
Key Performance Advantages & Product Benefits
Siab zog - rau - Qhov hnyav piv
Lub hollow core ntawm cov raj plaub lub raj txo qhov hnyav tag nrho cov qauv thaum khaws qhov tshwj xeeb khoov nruj. Qhov kev ua kom zoo dua no tso cai rau cov kws tsim qauv tsim kom sib zog, tus nqi ntau dua -cov txheej txheem hauv paus zoo thiab txo tag nrho cov kev xav tau ntawm steel tonnage.
Tight Dimensional Tolerances & High Flatness
Peb cov automated sizing mills tswj nruj nreem tswj ntawm qhov ntev, phab ntsa thickness uniformity, thiab kaum vojvoog sharpness. Qhov no geometric sib xws tau lees tias tus qauv mounting brackets, laser -txiav txuas daim hlau, thiab interlocking structural hardware dlhos zoo kawg nkaus rau ntawm -site.
Ua haujlwm tau zoo & Field Weldability
Formulated nrog qis Carbon Equivalent Value (CEV), peb lub raj raj muaj qhov zoo tshaj plaws weld kev ncaj ncees. Cov neeg ua haujlwm txhim kho tuaj yeem ua cov ntawv ceev ceev lossis siv vuam siv lub tshuab siv MIG, TIG, lossis cov txheej txheem stick txheej yam tsis tas yuav ua kom nyuaj ua ntej - lub sijhawm cua sov.
Smooth, Aesthetic Profile rau Exposed Steelwork
Nrog tsis muaj ntse sab hauv cov ces kaum los yog raug cov kab weld, duab plaub steel raj muaj qhov pom kev zoo nkauj, huv si. Cov nplai -dawb, du daim ntawv cog lus tshwj xeeb zoo nrog cov hmoov txheej, tiv thaiv primers, thiab hnyav-lub luag haujlwmKub-Dip Galvanizing (HDG)rau ntev - tiv thaiv corrosion.

Cov lus nug nquag nug (FAQ)
Q: Vim li cas qhov "Corner Radius" ntawm qhov txias - tsim cov kab plaub hau zoo li tseem ceeb thaum lub sij hawm tsim qauv?
A: Nyob rau hauv txias - tsim cov raj duab plaub, lub kaum sab xis ntawm lub vojvoog (qhov curvature qhov chaw tiaj tus sib ntsib) yog qhov tseem ceeb tshaj plaws. Cov qauv kev qhia tshwj xeeb (xws li ASTM A500) tswj hwm tias lub kaum sab xis sab nraud yuav tsum tsis txhob tshajpeb npaug ntawm nominal phab ntsa thickness (3t). Kev tswj lub vojvoog no yog qhov tseem ceeb vim tias lub kaum ntse ntse heev qhia txog qhov kev ntxhov siab hauv cheeb tsam uas tuaj yeem ua rau micro- tawg hauv qab thauj khoom, thaum lub kaum sab xis dhau los ua rau txo qis ntawm cov mating nto muaj rau vuam txuas daim hlau.
Q: Dab tsi yog cov txiaj ntsig ntawm kev siv lub voj voos hlau (RHS) hla qhov qhib kuv - nqaj rau cov kab ke?
A: Thaum kuv -beams muaj txiaj ntsig zoo rau kev tuav lub zog dabtsi yog khoov hauv ib qho kev taw qhia, lawv muaj kev cuam tshuam rau kev sib tw (torsional buckling) thiab kev hloov mus rau sab nraud. Lub raj plaub lub raj muaj qhov kaw - lub thawv profile, uas muab qhov zoo ib yam, siab torsional tiv thaiv nyob rau ntau lub axes. Qhov no ua rau RHS cov kab ntau ruaj khov nyob rau hauv ntau- cua thauj khoom, av qeeg rog, thiab eccentric load tej yam kev mob yam tsis tas yuav hnyav lateral cross-bracing.
Q: Koj lub zeb ua li cas kom ntseeg tau tias qhov ntev ntawm qhov vuam seam ntawm lub raj plaub tsis sib cais thaum lub sij hawm hnyav fabrication los yog dabtsi yog khoov?
A: Peb qhov siab - zaus induction (ERW) vuam kab txuas ntxiv saib xyuas qhov vuam - cheeb tsam kub thiab forging siab. Tom qab vuam, peb raug kuaj los ntawm txhua qhov kev tsim hluav taws xob ntau rau kev ua phem rau lub cevFlattening thiab Flare Testsqhov twg lub raj yog compressed los xyuas kom meej qhov sib koom ua ke sib tw lub zog ntawm lub hauv paus hlau. Tsis tas li ntawd, peb khiav tsis tu ncuaOnline Tsis yog -Kev Ntsuas Kev Ua Phem (NDT/Eddy Tam sim no)raws li 100% ntawm weld seam kom paub thiab tsis lees paub ib qho micro-voids lossis tsis muaj- ntawm- fusion anomalies.
Q: Cov raj hlau plaub puas tuaj yeem raug galvanized, thiab koj lub Hoobkas tiv thaiv kev sib tsoo thaum lub caij kub -dip li cas?
A: Yog, cov raj plaub yog zoo tagnrho rau kub -dip galvanizing. Txawm li cas los xij, txias- cov raj tsim muaj cov xauv- hauv kev tsim cov kev ntxhov siab uas tuaj yeem ua rau qee zaus ua rau muaj kev sib tw lossis sib tw thaum raug rau 450℃molten zinc da dej. Txhawm rau tiv thaiv qhov no, peb lub Hoobkas siv kev tswj kom txias thiab kev ntxhov siab- cov txheej txheem nyem thaum lub sijhawm ntsuas. Peb kuj tseem muab cov qauv tsim ua ntej-vented tubing kom ntseeg tau tias qhov siab - cov pa roj cua kub khiav dim yam tsis muaj kev nyab xeeb, xa cov khoom ncaj nraim, zoo ib yam.
