Basic txhais & Standard
Tag nrho specification: Cold Formed Welded Structural Hollow Section,EN 10219-1 / EN 10219-2
- S=Cov qauv hlau
- 355=Min yield zog355 MPa (t Tsawg dua lossis sib npaug li 16mm)
- J2=Charpy impact value Ntau dua los yog sib npaug rau 27J ntawm-20 degree(Tsawg kub tsis kam rau brittle puas)
- H=Hollow seem
Kev tsim khoom:Chav-kub txias yob txoj kev + ERW / HFW siab- zaus vuam / LASW
Muaj Cov Duab & Loj Ntau Yam (Brisk Steel Supply)
Cov txheej txheem ntau lawm: ERW / HFW
1. Cov khoom siv raw: Kub dov steel coils
2. Round yeeb nkab:Nruam txias yob-kev ua cov hlau sawb rau hauv cov duab cylindrical nrog seam → High- zaus induction vuam (seam fusion thiab siab vuam) → Weld hlaws tshem tawm, hauv - kab weld seam normalizing, sizing, thiab straightening (tus txheej txheem 5J12H EN 10).
3. Square thiab square kav: Ob txoj kev tsim khoom (ob qho tib si hauv ERW)
- Direct-formed square yeeb nkab:Steel strip yog ncaj nraim yob-tsim los ntawm ntau qhov kev hla mus rau hauv ib qho qhib square seem → Siab- zaus vuam los kaw lub seam; muab qhov siab tshaj plaws qhov tseeb thiab ceev tshaj plaws ntawm cov khoom loj.
- Hloov - mus rau - square forming:ERW puag ncig cov yeeb nkab yog tsim ua ntej → Tom qab ntawd txias- tsim / nias rau hauv cov duab siv cov yeeb nkab square tuag (feem ntau yog siv rau tuab - cov kav dej square thiab cov kav dej sib npaug).
4. Siv tau phab ntsa thickness: 1.5-16 hli; Hla-section: 20 × 20–500 × 500 mm; Hloov cov yeeb nkab sab nraud Tsawg dua lossis sib npaug li 610 mm (24 ntiv tes).
5. Cov yam ntxwv tseem ceeb:Nruam siab -cov kab ntau lawm ceev, nruj me ntsis kam rau ua, du nto tiav, tsis tshua muaj nqi ib tuj, thiab haum rau loj -scale zus tau tej cov qauv cov kav dej.
Production Process: LSAW
1. Cov khoom siv raw: Khoom hnyav steel phaj es tsis txhob coils
2. Round raj: JCOE Txheej Txheem - Ib leeg hlau phaj yog khoov rau hauv J-puab → C-puab → O-puab. Muab ob npaug rau-sided submerged arc vuam nrog vuam hlau muab tub lim cov seam longitudinal. Mechanical expanding yog siv los tso cov kev ntxhov siab sab hauv.
3. Loj hnyav -phab ntsa square/rectangular raj: Cov phaj hlau yog khoov rau hauv ob U- zoo li ib nrab plhaub, sib sau ua ke thiab welded los ntawm submerged arc vuam. Tsuas yog LSAW tuaj yeem tsim super- cov qauv hnyav hnyav hnyav.
4. Muaj ntau yam: Round yeeb nkab OD 406mm ~ 1524mm, phab ntsa thickness 6mm ~ 60mm; SHS / RHS tshaj 500mm sab ntev, phab ntsa thickness saum 16mm.

FAQ
Q: Dab tsi yog qhov tseem ceeb ntawm ERW thiab LSAW hauv tus nqi thiab xa khoom?
A: ERW txhawb nqa tsis tu ncua tsis siv neeg ntau lawm nrog cov nqi qis dua thiab lub sijhawm luv luv, tsim nyog rau kev txiav txim ntau export. LSAW yog tsim los ntawm ib tus zuj zus nrog cov hlau tuab, cov nqi tsim khoom ntau dua thiab cov voj voog ntau lawm, feem ntau yog siv rau cov phiaj xwm loj loj.
Q: Yuav ua li cas yog ERW round tubes thiab square rectangular raj tsim raws li?
A: ERW txais yuav kub dov steel kauj ua raw khoom. Lub steel strip yog txias- khoov tsis tu ncua mus rau hauv ib puag ncig tubular dawb paug, ces kaw los ntawm siab - zaus kuj welding los ua cov hlab puag ncig. Square thiab rectangular raj muaj ob txoj kev tsim: ncaj yob txoj kev los ntawm steel sawb, los yog txias nias tiav ERW round tubes rau hauv square & rectangular duab.
Q: Qhov luaj li cas yog haum rau ERW kav?
A: ERW puag ncig cov yeeb nkab sab nraud Tsawg dua lossis sib npaug ntawm 610mm, phab ntsa thickness 1.5-16mm. SHS / RHS ranges ntawm 20 × 20mm txog 500 × 500mm nrog phab ntsa thickness 1.5-16mm. Nws yog tus txheej txheem ntau lawm specification rau peb EN10219 S355J2H txias tsim hollow seem.
Q: Thaum twg LSAW yeeb nkab yog qhov tsim nyog xaiv?
A: Xaiv LSAW rau loj - txoj kab uas hla tuab - cov kav dej rau cov roj & roj xa mus, cov kav hlau txuas txuas, cov qauv hauv ntug dej hiav txwv, siab heev - nce cov kab tseem ceeb thiab cov chaw ntau pob hlau loj. Nws sib tw hnyav qis- qhov kub thiab txias ua haujlwm, siab bearing loads thiab tej yaam num uas yuav tsum tau tag nrho weld UT & RT nondestructive xeem.
