Corten B vs S355J2+N: Qib Equivalence, Qhov Sib Txawv Ntawm Cov Khoom thiab Hloov Cov Qauv Ntsuas

Thaum xaiv cov ntaub ntawv loj - cov haujlwm loj, cov kws ua haujlwm feem ntau ntsib qhov kev txiav txim siab tseem ceeb: xaiv ntawm atmospheric corrosion-cov hlau tsis muaj zog thiab siab - lub zog cov qauv carbon steel. Qhov kev ntsuam xyuas dav no tsom rauCorten BvsS355J2+Nqib sib npaug, tshawb nrhiav lawv qhov sib txawv ntawm cov tshuaj sib xyaw, kev coj tus cwj pwm, thiab cov qauv kev lag luam uas tswj hwm lawv cov kev hloov pauv.

Raws li tus thawj coj thoob ntiaj tebsteel manufacturers thiab exporter, GNEEtshwj xeeb hauv kev muab siab -kev ua tau zoo steel kev daws teeb meem. Nrog rau ntau tshaj 18 xyoo ntawm kev paub hauv kev lag luam, peb lub xeev - ntawm--art Hoobkas thiab cov khoom muag loj kom ntseeg tau tias peb tuaj yeem ua tau raws li cov kev xav tau tshaj plaws rauCorten B thiab S355J2+Ncov ntaub ntawv.

Txawm hais tias koj tab tom nrhiav rau daim hlau nyoos, txiav txiav, lossis kev txhawb nqa thoob ntiaj teb, GNEE yog koj tus khub ntseeg siab rau cov khoom lag luam zoo tshaj plaws.

GNEE's niaj hnub steel manufacturing Rhiav

Kom nkag siab qhovCorten B vs S355J2+N qib sib npaug, peb yuav tsum xub txhais lawv lub luag haujlwm tseem ceeb.Corten B(feem ntau categorized nyob rau hauv ASTM A588 Qib B) yog ib tug weathering steel tsim los tsim ib tug tiv thaiv xeb-zoo li patina thaum raug rau huab cua. Cov txheej no ua raws li kev thaiv, ua kom qeeb ntawm cov txheej txheem corrosion.

Ntawm qhov tod tes,S355J2+Nyog ib qho uas tsis yog - alloy structural steel tswj los ntawm EN 10025-2 tus qauv. Qhov "+N" txhais tau hais tias cov hlau tau raug ua kom zoo li qub, uas ua kom zoo dua cov qauv nplej los txhim kho toughness thiab weldability. Thaum ob lub steels muaj zog tawm los siab (feem ntau nyob ib ncig ntawm 355 MPa), lawv ib puag ncig kuj txawv heev.

Chemical Composition Analysis

Primary Differentiator nyob rau hauv lubCorten B vs S355J2+Nkev sib piv yog cov ntsiab lus alloying. Corten B yog enriched nrog Chromium (Cr), Nickel (Ni), thiab tooj liab (Cu). Cov ntsiab lus no yog lub luag haujlwm rau kev tsim ntawm "patina." S355J2+N tsis muaj cov ntsiab lus tshwj xeeb ntawm alloying, txhais tau tias nws yuav tsum muaj kev tiv thaiv sab nraud xws li pleev xim lossis galvanizing los tiv thaiv xeb hauv qhov chaw sab nraum zoov.

Mechanical Properties thiab Replacement Standards Analysis

Hauv ntau lub ntsiab lus engineering, cov lus nug tshwm sim: tuaj yeem S355J2+N hloov Corten B, lossis rov ua dua? Cov lus teb yog nyob rau hauvhloov cov qauv ntsuas. Mechanically, ob qib zoo sib xws. Lawv ob leeg poob rau hauv "355 MPa yield zog" qeb, ua rau lawv haum rau hnyav - cov ntaub ntawv cov qauv xws li txuas hniav, cov kav xa hluav taws xob, thiab cov thawv xa khoom.

Txawm li cas los xij, qhov hloov pauv tsis tshua muaj 1: 1 vim yog qhov cuam tshuam corrosion. Yog tias ib qhov project tsim los rau "kev tu vaj tu tsev- pub dawb" siv sijhawm ntev siv Corten B, hloov nws nrog S355J2+N yuav xav tau kev hloov pauv tseem ceeb hauv kev saib xyuas nyiaj txiag, vim tias tom kawg yuav tsum tau pleev xim tsis tu ncua.

Hloov pauv, siv Corten B qhov twg S355J2+N tau teev tseg yuav yog qhov kev xaiv "dhau- engineering" uas nce nqi pib yam tsis tau muab cov txiaj ntsig zoo yog tias ib puag ncig tsis zoo.

GNEE STEEL tam sim no koom nrogKev yuav khoom theem ntawm 100,000m³ tag nrho ntim ammonia cia tank project, muab siab - zoo steel phaj rau cov khoom tseem ceeb tank. Vim lub corrosive xwm ntawm ammonia thiab kev pheej hmoo ntawmAmmonia Stress Corrosion Cracking (SCC), qhov project yuav tsum nruj metallurgical tswj cov ntaub ntawv raws liEN 10028-3 tus qauv.

Ib qho tseem ceeb tshaj plaws kev xav tau ntawm qhov project no yog qhovnruj txwv ntawm qhov tseeb Yield Strength (Re)rau tag nrho cov ntaub ntawv qib NL2. Txhawm rau tiv thaiv SCC kev pheej hmoo hauv thaj chaw ammonia cia, covyield zog yuav tsum tsis pub tshaj 390 MPa, tsis hais tus nqi nominal teev nyob rau hauv tus qauv lossis phaj thickness ntau yam. Qhov kev xav tau no ua rau muaj kev xav tau ntau dua ntawm kev tswj cov txheej txheem steelmaking, kev kho cua sov kom ruaj khov, thiab kuaj cov khoom siv.

Raw siab -lub zog steel daim hlau npaj rau 100,000 m³ tag nrho ntim ammonia cia tank ntau lawm

Cov ntaub ntawv ntawm qhov project thiab kev xav tau

Qhov project feem ntau yog sivP355NL2 thiab P275NL2 normalized siab lub nkoj steel daim hlau, uas yog dav siv nyob rau hauv qis - kub cia tank vim lawv zoo heev toughness thiab weldability.

Cov kev qhia tshwj xeeb tseem ceeb suav nrog:

• Cov ntaub ntawv qib:P355NL2 thiab P275NL2 (Normalized)
• Yield zog:Standard yam tsawg kawg nkaus / Maximum txwv rau390 MPa ua
• Hardness:Tsawg dua lossis sib npaug rau 225 HBW hauv cov khoom siv hauv paus
• Kev ntsuam xyuas cuam tshuam:Charpy-V ntsuas ntsuas ntawm-50 degree, yam tsawg kawg 27J
• Ntawv pov thawj:TS EN 102043.1 daim ntawv pov thawj, nrog yeem3.2 ntawv pov thawj

Cov kev cai nruj no xyuas kom meej tias cov hlau phaj tswj cov khoom ruaj khov thiab ua haujlwm siab rau ammonia-ua rau muaj kev ntxhov siab corrosion thaum lub sijhawm ua haujlwm ntev-.

Precision dov thiab tsim cov hlau phaj rau hauv cov ntu nkhaus rau 100,000 m³ ammonia cia tank.

Project Plate Quantity thiab Thickness Distribution

Tag nrho cov hlau xav tau rau qhov project no ammonia cia tank yog ob peb txhiab tons, feem ntau faib thoob plaws ntau lub tank:

P355NL2 - Sab hauv & Outer Tank Plhaub daim hlau

• Cov chav kawm qis qis:50 hli thickness – kwv yees li . 2,000 tons
• Cov chav kawm Middle plhaub:25 hli thickness – kwv yees li . 1,400 tons
• Cov chav kawm Upper shell:10 hli thickness – kwv yees li . 500 tons

P275NL2 - Tank hauv qab phaj

• Thickness:10–15 mm – approx . 750 tons
