Cov txheej txheem tsim khoom
- Cov no yog tsim los ntawm kub- dov steel billets ntawm qhov kub thiab txias thiab poob rau hauv ob pawg tseem ceeb: kub- dov seamless tuab - phab ntsa square tubes thiab kub - dov welded tuab - phab ntsa square tubes.Hauv kev lag luam, phab ntsa tuab ntawm 10 hli lossis siab dua yog feem ntau cais raws li "thick-walled" specification; cov phab ntsa raj yog ntom thiab tsis muaj lamination, featuring ib tug niaj hnub microstructure, thaum lawv load- bearing thiab cuam tshuam-kuj muaj peev xwm nyob deb tshaj cov qauv txias- tsim nyias-walled square tubes.
kub- dov seamless tuab-walled square tubes txheej txheem (phab ntsa thickness Ntau dua los yog sib npaug rau 10mm, hnyav-cov kav dej seamless)
- Round billet tshuaj xyuas & txiav → Billet cua sov (1100 ~ 1250 degree) → High -siab dej descaling → Rotary tho (hollow niam raj) → Nruam phab ntsa dov → Reheating ntawm lub raj roughing → Kub dov txoj kev (round raj rau square profile) → Straighten dej Tsau -ntev txiav → Hydrostatic test + UT kev tshuaj xyuas → Mechanical property test → Surface treatment (dub xim / anti- xeb roj / kub-dip galvanizing) → Marking → Warehouse & shipping
Kub-rolled, tsim, thiab welded tuab-walled square tube (ERW/SAW tuab-walled welded yeeb nkab, phab ntsa thickness Ntau dua los yog sib npaug li 10 mm)
- Kub dov hnyav phaj / kub dov coil tshuaj xyuas → Uncoiling & leveling + ntug milling → Yob txoj kev mus rau hauv ib puag ncig raj dawb paug → HF welding / submerged arc vuam → Sab hauv & txheej weld hlaws tshem tawm → Online kev ntxhov siab nyem cua sov → Kub dov txoj kev (round to square) → Txias & rsquo; Tsau -ntev txiav & xaus trimming → Weld NDT + kev tshuaj xyuas qhov ntev → Anti- kev kho corrosion → Marking & packing
Mainstream Standards & Qib
- European Standards:EN 10210 (Kub-Tiav ntu ntu), EN 10219; Qib S275J0/J2, S355JR/J0/J2, S355NL
- ASTM Cov Qauv:ASTM A500 Qib B / Qib C (feem ntau siv rau txawv teb chaws infrastructure)
Core Advantage
- Lub zog loj nrog kev ua haujlwm zoo heev rau kev khoov, torsion, thiab compression; zoo tagnrho rau hnyav -load ncej
- Siab -kub kub dov tshem tawm kev ntxhov siab sab hauv, txo qhov kev pheej hmoo ntawm kev tawg thaum vuam, txiav, lossis khoov
- Thick-cov qauv phab ntsa muaj kev nruj nruj, haum rau hnyav-cov khoom siv hauv lub hauv paus thiab loj- nplai steel qauv
- Precision dimensional kam rau ua; ntug ncaj thiab kaum qhov tseeb khaws cia hauv cov qauv kev lag luam siab
Kev Xaiv Kev Kho Hniav (Standard for Export)
- Dub Kub-Rolled tiav (Black Tube):Thawj zeb-tiav oxide nto; tus nqi qis tshaj; feem ntau siv rau sab hauv steel qauv
- Kub-dip Galvanized:Zinc txheej thickness ntawm 80-120 μm; qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv corrosion sab nraum zoov
- Anti- xeb roj, primer txheej, xim dub txheej
Thick{0}}walled VS Nyias-walled
- Siab dua Bearing Capacity & Cov qauv ruaj khovNrog rau qhov loj dua modulus, tuab phab ntsa square tubes muab zoo heev compression, dabtsi yog khoov thiab torsion kuj. Lawv nyob ruaj khov nyob rau hauv lub siab hnyav, lateral torque thiab dynamic cuam tshuam, thaum nyias - phab ntsa hlab yog yooj yim deform thiab vau nyob rau hauv hnyav loads.
- Uniform Structure & Anti-Kev qaug zogCov txheej txheem kub dov tshem tawm cov kev ntxhov siab sab hauv nrog cov qauv hlau ntom ntom. Cov raj tiv taus qaug zog thiab tawg nyob rau hauv ntev - lub sij hawm vibration thiab alternating load. Txias-tsim nyias- cov phab ntsa cov hlab ntsha muaj kev ntxhov siab nyob ntawm cov ces kaum thiab nws yuav ua rau tawg.
- Zoo heev Machinability & WeldabilityPhab ntsa tuab txaus kom tsis txhob vuam hlawv- dhau. Nws txhawb nqa bevel vuam, milling, drilling thiab threading nrog kev sib txuas siab zog. Nyias-cov hlab ntsa yog yooj yim rau hlawv thiab deform thaum vuam, tsis haum rau hnyav- ua haujlwm.
- Loj Corrosion Allowance & Lub neej ua haujlwm ntevPhab ntsa tuab muab cov npoo txaus corrosion. Txawm tias tom qab ntev -lub sij hawm sab nraum zoov thiab hauv av corrosion, qhov ua haujlwm tau zoo- ntu kev coj tus kheej tau khaws cia, ua kom lub neej ntev ntawm txoj haujlwm.

FAQ
Q: Dab tsi phab ntsa thickness txhais tau tias yog kub dov tuab phab ntsa square raj?
A: Hauv cov qauv kev lag luam steel, cov raj square nrog phab ntsa thickness Ntau dua lossis sib npaug li 10 hli raug cais raws li tuab - cov khoom siv phab ntsa. Peb lub Hoobkas tsim cov phab ntsa tuab tuab xws li 10mm txog 50mm phab ntsa tuab, thiab cov phab ntsa hnyav ntxiv tuaj yeem kho raws li qhov xav tau.
