ERW Structural Steel Pipes: Hom, Cov Qauv, thiab Kev Siv
ERW (hluav taws xob tsis kam welded) cov yeeb nkabyog lub siab -kev ua tau zoo txhua yam khoom tsim los ntawm siab- zoo steel coils. Siv high- zaus vuam (HFW) tshuab, lub seam ntev yog forged ntawm kev kub ceevtsis muaj filler hlau, ua ib qho ncaj- seam yeeb nkab nrog cov phab ntsa tuab tuab thiab kev ua haujlwm siab. Piv nrog rau cov khoom steel, ERW cov yeeb nkab muaj lub zog zoo tshaj - rau - qhov hnyav piv, ua rau nws yog ib qho khoom siv ntau yam hauv kev ua liaj ua teb, kev lag luam thiab kev tsim kho.

Qhov ntau thiab tsawg thiab qhov kawg tiav
Sab nraud txoj kab uas hla:
21.3 hli (1/2 nyob rau hauv.) mus txog 610 hli (24 nyob rau hauv.).
Phab ntsa thickness:
1 hli mus txog 22 hli, npog lub teeb thav duab rau hnyav load-cov kabmob.
Ntev:
0.5 m txog 20 m, suav nrog kev cai txiav - mus rau - ntev kom txo qis ntawm - qhov chaw pov tseg.
End finishes:
square xaus (ncaj, pom lossis teeb ci) thiab beveled xaus rau kev sib txuas sib txawv.
Kev Siv Hluav Taws Xob thiab Kev Tsim Kho
Infrastructure:
sib sib zog nqus piling rau cov chaw nres nkoj, choj txhawb kab, siab - lub zog scaffolding.
Industrial thav duab:
ua liaj ua teb machinery, warehouse racking, siab -nce shelving.
Aviation thiab thauj:
aircraft hangar lug thiab tsheb yob tawb.
Municipal Utilities:
siab -cov kav dej muaj zog rau cov tsis yog- cov kua xa tawm tseem ceeb thiab kev xa xov cable.
Quality Assurance thiab Protection
Kev ntseeg tau ntawm cov qauv yuav tsum tau ua pov thawj: thib peb- kev tshuaj xyuas tog, siab - kev ntsuas hydrostatic siab thiab ntsuas qhov ntsuas qhov tseeb. Rau kev pabcuam sab nraum zoov lossis faus, cov kav dej tau kho nrog kub -dip galvanizing, xim dub lossis siab -kev ua haujlwm tiv thaiv- xeb roj. Tag nrho cov ntaub ntawv traceability yog muab los ntawm Mill Test Certificate (MTC).
Cov lus nug nquag nug (FAQ)
Q: Vim li cas ERW nyiam dua seamless rau cov qauv thav duab?
ERW muaj cov phab ntsa tuab zoo sib xws thiab zoo dua qhov ntev ntev ntawm tus nqi qis dua seamless, ua rau nws zoo tagnrho rau siab -precision structural los ua ke.
Q: ASTM A500 square raj puas tuaj yeem siv rau cov kua dej siab?
No. A500 yog cov qauv kev qhia tshwj xeeb; Kev pabcuam kua dej siab xav tau ASTM A53 lossis API 5L cov khoom lag luam uas yuav tsum tau kuaj cov xau.
Q: Puas yog qhov vuam seam cuam tshuam rau lub zog ntawm cov qauv?
Tsis yog. Nrog kev tsim khoom zoo thiab 100% NDT, lub vuam yog tsim los ua kom haum lossis tshaj lub zog ntawm cov niam txiv steel.
Q: Dab tsi yog qhov txiaj ntsig ntawm kev ua kom txias?
Cold forming induces strain hardening, raising yield zog thiab ua kom ntse, huv si ces kaum xav tau rau square thiab rectangular profiles.
Q: Cov kav dej muaj kev tiv thaiv zoo li cas thaum thauj khoom?
Cov kav dej tau muab qhwv, coated nrog cov kua roj vanish lossis los tiv thaiv- xeb roj, thiab qhwv hauv cov hnab ntim dej tsis muaj dej kom txog thaum muaj xwm txheej zoo.
Q: Qhov siab tshaj plaws txoj kab uas hla yog dab tsi?
Feem ntau 610 mm (24 in.) rau ERW; Cov qauv loj dua yog tsim los ntawm LSAW lossis kauv vuam.
