Q235B ERW welded puag ncig kav
Q235B ERW Steel Pipe Nqe lus piav qhia
Q235B ERW welded puag ncig kavyog cov ncaj- seam tubes ua los ntawm Q235B carbon structural steel, koom nrog siab - zaus hluav taws xob tsis kam vuam (ERW) thiab muab rau GB / T 3091 (tsawg- cov kua xa tawm) lossis GB / T 13793 (longitudinal welded raj). Lub hauv paus hlau yog qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa (tsawg dua lossis sib npaug li 16 hli) thiab lub zog tensile ntawm 370-500 MPa, nrog rau kev tiv thaiv Charpy ntawm 27 J ntawm +20℃. Lawv yog qhov kev xaiv ua ntej rau kev tsim vaj tsev, scaffolding, thiab tsis yog -tseem ceeb tsawg- cov kab dej siab uas tus nqi thiab weldability tseem ceeb tshaj qhov ntsuas siab.
Txawm hais tias qee zaum lub npe siv hauv khw,Q235B carbon steel ERW yeeb nkabyog ib tug dawb carbon structural steel nyob rau hauv GB / T 700-2006 - tsis yog ib tug hlau alloy. Lub "Q" qhia txog lub zog tawm los, "235" qhov 235 MPa yam tsawg kawg nkaus tawm los rau ntu txog li 16 hli tuab, thiab "B" cov chav kawm zoo uas ntxiv chav - qhov ntsuas kub ntawm qhov ntsuas. Qhov kev sib xyaw ua ke yog dab tsi ua rau Q235B qib workhorse rau fabricated thiab welded qauv thoob plaws Tuam Tshoj thiab nws cov lag luam xa tawm.
Raws li ib tugQ235B hluav taws xob kuj welded yeeb nkab, cov khoom pib ua kub- dov sawb, txias- ua rau hauv ib puag ncig profile, thiab yog welded raws ib leeg ntev seam uas tsis muaj hlau muab tub lim. GNEE cov khoom sivQ235B ERW welded steel yeeb nkabnyob rau sab nraud diameters ntawm 21.3 hli mus rau 610 hli (DN15–DN600, ¾ nyob rau hauv–24 nyob rau hauv) thiab phab ntsa thicknesses los ntawm 0.6 mm mus rau 20 mm, nyob rau hauv ntev ntawm 6 m, 9 m los yog 12 m, tiaj-kawg, beveled, los yog kub-dip galvanized.Xa koj OD × phab ntsa, kom muaj nuj nqis thiab lo lus uas peb.

FAQ
Puas yog Q235B ERW yeeb nkab yog hlau alloy?
Tsis muaj.Q235B carbon steel ERW yeeb nkabyog ib tug dawb carbon structural steel nyob rau hauv GB / T 700-2006. Nws tsuas muaj cov seem seem ntawm Mn, Si, P thiab S thiab tsis yog "alloy steel." Txhua daim ntawv teev npe nws "Q235B alloy steel yeeb nkab" yog siv lub sijhawm tsis raug thiab yuav tsum tau kho.
Dab tsi yog qhov txawv ntawm GB / T 3091 thiab GB / T 13793 rau Q235B ERW yeeb nkab?
GB/T 3091-2015 npog welded steel kav rau qis- siab xa kua (dej, cua, roj); GB/T 13793-2016 npog longitudinal hluav taws xob-kuj-welded steel hlab rau cov qauv siv thiab siv tshuab. Tib Q235B lub hauv paus hlau, sib txawv siv qhov kawg - xaiv GB / T 3091 rau cov kab dej thiab GB / T 13793 rau cov qauv.
Q235B vs S235JR - lawv zoo li cas?
Rau feem ntau cov haujlwm yog. Q235B (GB/T 700) thiab S235JR (EN 10025-2) qhia 235 MPa yam tsawg kawg nkaus tawm los thiab ib tug +20℃/ 27 J Charpy cuam tshuam, yog li lawv raug kho raws li qhov sib npaug. US yeeb nkab-daim ntawv sib npaug yog ASTM A53 Hom E Qib B.
Q235B ERW yeeb nkab tuaj yeem tiv taus dab tsi?
Hauv luv, lubQ235B ERW yeeb nkab siab ntsuastsis yog tus lej catalog tas. Q235B ERW yeeb nkab yog qhov qis - cov yeeb nkab dej siab (GB / T 3091), tsis yog lub siab ruaj khov - ntsuas ASME yeeb nkab. Kev ua haujlwm siab nyob ntawm OD, phab ntsa thickness thiab cov qauv tsim, yog li nws yuav tsum tau suav nrog tus qauv siv tsis yog hais raws li ib qho kev ntsuas bar. Rau qhov tsis yog- qhov tseem ceeb tsawg- cov kab dej / cua nws yog qhov kev xaiv tus qauv.
Qhov hnyav ntawm Q235B ERW yeeb nkab suav li cas?
Siv tus qauv steel- yeeb nkab hnyav formula: hnyav=0.02466 × WT(mm) × (OD(mm) − WT(mm)) kg/m. Rau 48.3 hli OD × 3.5 hli phab ntsa raj uas yog 0.02466 × 3.5 × 44.8 ≈ 3.87 kg / m. Paub meej nrog cov phab ntsa ntsuas tiag ua ntej tus nqi.
Q235B ERW yeeb nkab puas tuaj yeem kub -dip galvanized?
Yog lawm.Q235B ERW yeeb nkab galvanizedlos ntawm kub-dip zinc feem ntau yog siv rau sab nraum zoov tes tuav, laj kab thiab ncej, coated rau GB / T 13912 / ISO 1461. Galvanizing yog ua tiav siv tom qab vuam thiab tsis hloov cov qib hauv paus.
Puas yog Q235B ERW yeeb nkab xav tau preheating rau vuam?
Tsis muaj tsawg dua lossis sib npaug li 0.20% carbon,Q235B ERW yeeb nkab vuamlos ntawm phau ntawv arc, CO₂ lossis txoj kev tiv thaiv yuav tsum tsis muaj preheat lossis tom qab-weld heat treatment. Qhov ntawd yog lub ntsiab yog vim li cas nws thiaj li dav fabricated rau ntawm qhov chaw.
Q235B vs Q235A - uas kuv yuav yuav?
Q235B ntxiv kev lees paub +20℃cuam tshuam kev xeem uas Q235A tsis muaj. Rau ib qho welded lossis load-cov qauv kabmob, Q235B yog lub neej ntawd muaj kev nyab xeeb; xaiv Q235A tsuas yog rau qhov tsis yog - qhov tseem ceeb uas tsis muaj qhov yuav tsum tau muaj zog. Rau kev pabcuam txias txav mus rau Q235C (0 degree) lossis Q235D (−20 degree).
