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 li 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

 

P275NL2 - Ncua lub ru tsev

• Thickness:5–8 mm – approx . 180 tons

 

S275JR - Lub Tsev Sab Nraud (Ambient Structure)

• Thickness:10 mm – approx . 450 tons

 

Txhawm rau txhim kho tank fabrication efficiency thiab txo cov voj voog ncig, qhov project kuj xav taudav hlau daim hlautxhawm rau txo qis cov pob qij txha welding, uas yuav pab txo qis kev pheej hmoo ntawm SCC hauv kev pabcuam ammonia.

 

Tsim steel ntu qhwv thiab racked rau kev tiv thaiv, npaj rau 100,000 m³ ammonia cia tank sib dhos.

 

GNEE STEEL muab siab -precision steel phaj dov thiab lub tog raj kheej tsim cov kev daws teeb meem rau lub tank manufacturers thoob ntiaj teb.Xa peb koj cov phaj specifications los yog fabrication drawings rau ib tug ceev hais.
