Plak asye SA302GrB se yon sèl kalite asye alyaj Molybdène nan ASME SA302 / SA302M, SA302 Klas B totalman egal aA302 Klas Bnan ASTM A302 / A302 spesifikasyon asye.Sepandan ki klas asye nan spesifikasyon asye Chinwa ki ekivalan a SA302 Klas B plak asye?
Konparasyon pwopriyete mekanik ak konpozisyon chimik ki soti nan tablo ki anba a, nou jwenn plak asye 15CrMoR nan estanda asye GB/T713 pou chodyè bilding asye itilize trè menm jan akSA302GRB plak asye.Yo tout bezwen Mo% pi wo pase 0.45% lè yo founi ak tretman chalè ak Normalized.Else,15CrMoR plak asyegen plis restriksyon pou P% ak S% lè woule.
SA302 Klas A plak asyeitilize pou chodyèr fabrike ak veso presyon ak Mo (Min.0.45%) alloy.15CrMoR plak asye tou yo itilize pou chodyèr ak ak alyaj Mo nan 0.45-0.6% nan analiz chalè woule.
Konparasyon nan konpozisyon chimik ak fòs mekanik nan tablo anba a, nan pifò sitiyasyon, plak asye SA302 Klas A egal a plak asye 15CrMoR lè yo bati chodyèr ak veso presyon.

Senaryo Aplikasyon: Ekivalans nan Pratik ak Konsèy pou Seleksyon
Tou deSA302GrB presyon veso asye plakepi15CrMoR cho woule plak asyeyo lajman itilize nan chodyèr, veso presyon, ak echanjeur chalè, ak ekivalans yo valide nan anpil pwojè endistriyèl:
Aplikasyon tipik nan SA302GrB
Pwojè ki sètifye nan lòt bò dlo ASME-: Réacteurs pétrochimiques, veso pwesyon pou tretman gaz natirèl, ak tib chodyè chodyè.
Senaryo gwo-presyon, ba-tanperati: Réacteurs Idwojènasyon, ekipman oksilyè plant GNL, ak aparèy chofaj presyon wo-izin tèmik.
Avantaj: rekonesans estanda mondyal senplifye akizisyon trans--fwontyè ak sètifikasyon pwojè, sa ki fè li yon chwa prensipal pou pwojè EPC entènasyonal yo.
Aplikasyon tipik nan 15CrMoR
Domestik GB-pwojè estanda: chabon-tanbou chodyè plant elektrik, endistri chimik reyaktè sentèz metanol, ak veso presyon tretman dlo egou yo.
Anviwònman tanperati ki wo -korozif: Ekipman pwodiksyon asid silfirik, gwo fò won tretman ilfid idwojèn, ak eleman echanj chalè chodyè ensinerasyon fatra.
Avantaj: Pri -efikasite (10-15% pi ba pase SA302GrB) ak chèn ekipman domestik ki gen matirite, apwopriye pou pwojè domestik ak kontwòl pri strik.
