P265GH Pressure Vessel Steel Plate

P265GH Chitsulo - Chosamva Kutentha & Non-Alloy

Kodi P265GH ndi chiyani?
Gulu la P265GH ndi Zitsulo Zolimbana ndi Kutentha Kwambiri zomwe zimafotokozedwa mu EN 10028 system. Ndizitsulo zopanda aloyi. Zinthuzo zimapangidwira ntchito zotentha kwambiri. Chifukwa chake amagwiritsidwa ntchito kwambiri pakutentha kwambiri m'gawo lamafuta ndi gasi, mafakitale opanga mankhwala ndi magawo a petrochemical.

Ndilo chinthu chachikulu chopangira ma boilers ndi zotengera zopanikizidwa. Zimakhazikika pozisunga kutentha kwa 890 mpaka 950 ° C popanda kugwira; Kutentha kumadutsa mu makulidwe a mbale.

EN 10028 ndi chiyani?
P265GH imadziwika mu muyezo wa EN 10028. Ndi mulingo wazinthu zaku Europe "Zopangidwa ndi Flat zopangidwa ndi zitsulo zokakamiza". Komanso muyezo umakwirira "Zitsulo zopanda aloyi ndi aloyi zokhala ndi kutentha kwapamwamba". Muyezowu udasindikizidwa mchaka cha 2009.

Chifukwa chiyani P265GH imatchedwa A516 grade 60 Steel?
P265GH ndiye mtundu wa alloy mu muyezo waku Europe, womwe umatchedwanso A516 grade 60 mumiyezo ya ASME/ASTM. Opanga ambiri amati amatsatira zonse za EN 10028 ndi ASME/ASTM zachitsulo A516 kalasi 60.

Terminology
GH - ndi yabwino kuti igwiritsidwe ntchito pamatenthedwe okwera ogwirira ntchito
NH - pa ntchito yapakatikati mpaka kutentha kwambiri
NL1 - ndi yabwino kuti igwiritsidwe ntchito kutentha kochepa
NL2 - ndiyoyenera kugwiritsidwa ntchito makamaka potentha kwambiri
