EN Pressure Vessel Steel

Kev Qhia Qib Siab & Cov Lus Qhia Tshwj Xeeb

A. Tsis yog-Alloy Carbon Steels (EN 10028-2)

Cov no yog cov feem ntau "boiler steels," siv rau chav nruas, tso tsheb hlau luam, thiab cov khoom siv hluav taws xob ua haujlwm ntawm qhov kub siab.

B. Fine-Grain Steels (EN 10028-3)

Cov qib no muab cov txiaj ntsig zoo dua thiab ua kom zoo rau qhov sib txawv ntawm qhov kub thiab txias (NH rau qhov kub siab, NL1 / NL2 rau qhov kub tsawg).

NH Qib:Rau siab -kev pabcuam kub.

NL1/NL2 Qib:Rau qis-kub toughness (NL2 yog kuaj ntawm -50℃).

C. Alloy Steels (Creep-Resistant & Kub Kub)

Tshwj xeeb alloyed nrog Molybdenum (Mo) thiab Chromium (Cr) los tiv thaiv "creep" (deformation) ntawm qhov kub thiab txias tsis tu ncua.

3. Master Equivalent Chart: EN vs. ASTM vs. GB

Kev nkag siab txog tus ntoo khaub lig- tus qauv kev sib raug zoo yog qhov tseem ceeb rau cov haujlwm EPC thoob ntiaj teb thiab kev yuav khoom thoob ntiaj teb.

Nco tseg: Cov qib sib npaug tsis zoo ib yam. Nco ntsoov xyuas:

Impact test xav tau

Kev kho cua sov

Daim ntawv pov thawj (ASME / PED / EN10204 3.1)

4. Kev xaiv cov khoom siv los ntawm kev ua haujlwm ib puag ncig

Tsawg-Tsub & Cryogenic Service (tsawg dua lossis sib npaug li -20 degree)

Rau cov khoom siv xws li LNG tso tsheb hlau luam lossis Arctic siab hlab ntsha, kev cuam tshuam toughness yog thawj qhov kev txhawj xeeb.

Pom zoo: P355NL1, P355NL2, 16MnDR.

Nco tseg:P355NL2 tshwj xeeb yog kuaj rau Charpy V-qhov cuam tshuam ntawm-50 degree, xyuas kom tsis txhob nkig tawg nyob rau hauv huab cua txias.

Intermediate & High -Kev Pabcuam Kub (200℃- 600 degree)

Rau chav boilers, fais fab nroj tsuag hlab ntsha, thiab refineries.

Pom zoo: P265GH, P355GH, 16Mo3, 13CrMo4-5.

Nco tseg:Alloyed qib zoo li16 hmo 3Nws yog ib qho tsim nyog thaum qhov kev pabcuam kub siab tshaj 450℃los tiv thaiv kev nkag.

5. Kev Pov Hwm Zoo: PVQ thiab Ntawv Pov Thawj

Txhua EN Pressure Vessel Steel phaj yuav tsum tau ua raws liPVQ (Pressure Vessel Quality). Qhov no suav nrog:

Kev txwv nruj nruj:Tsawg Phosphorus (tsawg dua lossis sib npaug li 0.025%) thiab Sulfur (tsawg dua lossis sib npaug li 0.015%) kom paub meej purity.

Internal Soundness:100% Ultrasonic Testing (UT) los kuaj xyuas cov laminations.

Kev ua raws li MTC:Cov ntaub ntawv yog muab nrogEN 10204 3.1(Mill certified) los yogEN 10204 3.2(Third- tog tau pom los ntawm cov koom haum xws li DNV, BV, lossis SGS).

6. Cov lus nug nquag nug (FAQs)

Q: Qhov txawv ntawm P355NH thiab P355NL2 yog dab tsi?
Ob leeg yog cov zoo- cov nplej hlau nrog 355 MPa yield zog. Txawm li cas los xij,P355 NHyog tsim los rau chav rau siab - qhov kev pab kub (kuaj ntawm -20 degree), thaumP355 NL 2yog tsim los tshwj xeeb rau qis - qhov kub thiab txias kev pab cuam, nrog guaranteed cuam tshuam toughness ntawm-50 degree.

Q: Kuv puas tuaj yeem siv P265GH hloov A516 Qib 60?
Yog, nyob rau hauv feem ntau cov kev siv functional lawv yog sib npaug. Txawm li cas los xij, yog tias koj qhov project yogASME -coded, koj yuav tsum siv A516. Yog nws yogPED- ntawv pov thawjrau kev ua lag luam nyob sab Europe, P265GH feem ntau xav tau.

Q: Vim li cas 16Mo3 thiaj li nrov nyob rau hauv refinery tej yaam num?
16Mo3 yog ib qho kev lag luam hlau hlau uas muab cov ntsiab lus molybdenum tsim nyog los tiv thaiv siab - kub deformation thiab hydrogen nres, ua rau nws zoo tagnrho rau cov cua kub exchangers thiab reactors.

Q: Dab tsi yog "P" thiab "GH" sawv cev rau EN qib?

P:Stands rau "Pressure" kev pabcuam.

GH:Stands rau "Npaj / Kub" (siab kub zog).

NH/NL:Stands rau "Normalized/High-Temp" thiab "Normalized/Low-Temp".

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 tsuas 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-.
