P275N Pressure Vessel Steel Plate

EN10028 P275N mbale zitsulo / pepala, pansi pa muyezo wa EN, tikhoza kuganizira P275N mbale zitsulo / pepala kwa boilers ndi Pressure Vessels steels. zitsulo mbale ndi pepala amene makamaka ntchito pomanga zotengera kuthamanga ndi boilers ndi mapaipi madzi otentha.

Pansi pa EN10028_3, mbale yachitsulo P275N iyenera kukhala pansi pazikhalidwe zoperekera nthawi zonse pokonza. Zitsulo za P275NH ndi P275N zomwe zimagwiritsidwa ntchito kwambiri muzotengera zopopera ndi ma boilers zimasiyana ndi mbale zina zachitsulo za carbon_manganese zomwe zimakhala ndi kukana kwambiri kupanikizika pa kutentha kulikonse zikagwiritsidwa ntchito.
