ASTM A516 Qib 70 vs. European sib npaug P355GH: Kev sib piv kev sib piv rau cov ntawv siv lub nkoj siab
Thaum muab cov pa roj carbon steel phaj rau cov hlab ntsha siab thiab boilers, engineers thiab procurement specialists feem ntau ntsib ib lo lus nug tseem ceeb:Dab tsi yog European sib npaug ntawm ASTM A516 Qib 70?Cov lus teb ncaj qha yogTS EN 10028-2 P355GH. Txawm li cas los xij, thaum ob qib no feem ntau hla - hais txog, lawv tsis zoo ib yam. Nkag siab txog qhov hloov maj mam tab sis qhov sib txawv tseem ceeb hauv cov qauv, cov khoom siv kho tshuab, thiab kev ua kom haum ib puag ncig yog qhov tseem ceeb rau kev txhim kho kev nyab xeeb thiab nqi.
Kab lus no muab ib qho hauv - qhov tob, kev sib piv ntawmASTM A516 Qib 70(ASME SA516 Gr 70) thiab nws cov European "sib npaug,"P355GH, qhia txog qhov zoo ntawm Asmeskas tus qauv hauv qee qhov kev ua haujlwm.

Standard Specifications thiab Tsim Lub Hom Phiaj
ASTM A516 Qib 70 (ASME SA516 Gr 70)
Txheem:ASTM A516 / ASME SA516.
Title:Standard Specification for Pressure Vessel Phaj, Carbon Steel, rauNruab nrab- thiab qis dua- Kev Pabcuam Kub .
Ntsiab tsom xam:Optimized rauncos toughnessthiab tiv thaiv kom tawg tawg ntawm qhov kub thiab txias.
ASME Boiler Code:SA516 tau pom zoo tshwj xeeb rau kev siv raws li ASME Boiler thiab Pressure Vessel Code (BPVC), uas yog qhov yuav tsum tau ua hauv North America thiab lees paub thoob ntiaj teb.
Txheem:TS EN 10028-2.
Title:Cov khoom lag luam tiaj tus ua los ntawm cov hlau rau lub hom phiaj siab - Ntu 2: Tsis yog- alloy thiab alloy steels uas tau teev tsegelevated kub khoom .
Ntsiab tsom xam:Tsim los rau siab - qhov kub thiab txias kev pab cuam (ceep resistance) thiab siab qhov chaw ua hauj lwm nyob rau hauv lub creep range .
Critical Takeaway:A516 Gr 70 yog "Tsawg-Tsub" steel, thaum P355GH yog "siab-Tsub" steel.
Daim Ntawv Thov Scenario: Yuav Siv Qhov Twg?
Xaiv ASTM A516 Qib 70 Thaum
Kev ntsuas kub yog qis dua -20 degree:Cia tso tsheb hlau luam rau cov tub yees roj, cov kev pabcuam cryogenic, lossis cov khoom siv caij ntuj no hauv Canada / Russia.
Yuav tsum muaj ASME Code Stamp:Rau cov nkoj xa tawm mus rau Tebchaws Meskas lossis Canada, ASME SA516 yog qhov yuav tsum tau ua. EN P355GH tsis tuaj yeem tsim nyog rau ASME stamping .
Sour Service (Wet H₂S):Cov txheej txheem muaj nyob ntawm HIC kuaj daim hlau ua A516 Gr 70 qhov kev xaiv zoo tshaj plaws rau kev lag luam roj thiab roj.
Xaiv EN P355GH Thaum twg
Ua haujlwm kub siab tshaj 450 degree:P355GH muaj kev nkag siab zoo dua thiab oxidation stability ntawm qhov kub siab heev.
Qhov project yog nruj me ntsis hauv EU / CE Market:Txhawm rau ua raws li Cov Lus Qhia Cov Khoom Siv Siab (PED), siv EN cov qauv yog txoj hauv kev uas tsis muaj kev tiv thaiv tsawg.
Kev poob phaus yog qhov tseem ceeb:Lub zog tawm los ntau dua (355 MPa) tso cai rau cov neeg tsim qauv siv cov phaj nyias nyias rau tib lub siab, txo qhov hnyav tag nrho.
