P265GH Pressure Vessel Steel Plate

P265GH Simbi - Inodzivirira Kupisa & Isiri-Alloy

Chii chinonzi P265GH?
Giredhi P265GH ndiyo Heat Resistant Pressure Vessel Steels inotsanangurwa muEN 10028 system. Isimbi isiri-alloy. Nyaya yacho yakagadzirirwa kushandiswa kwekushisa kwepamusoro. Naizvozvo inonyanya kushandiswa mukupisa kupisa kwepamusoro muchikamu cheoiri uye gasi, maindasitiri ekugadzira makemikari uye petrochemical sector.

Icho chinhu chikuru chekugadzira zvinhu zvema boilers uye midziyo yakamanikidzwa. Inogadziriswa nekuichengeta ichitarisana nekupisa kwe890 kusvika ku950 ° C pasina kubata; kupisa kunopfuudzwa kuburikidza nehupamhi hweplate.

Chii chinonzi EN 10028?
P265GH inotaridzwa muchiyero EN 10028. IEuropean material standard ye "Flat products made of steels for pressure purposes". Uyezve chiyero chinovhara "Isiri-alloy uye alloy masimbi ane yakakwira tembiricha zvivakwa". Iyo standard yakaburitswa mugore ra2009.

Nei P265GH ichinzi A516 giredhi 60 Steel?
P265GH ndiyo alloy yezita muEuropean standard, inonziwo A516 giredhi 60 muASME/ASTM zviyero. Vazhinji vagadziri vanoti vanoenderana nezvose zvakatemwa zve EN 10028 uye ASME/ASTM zvinhu A516 giredhi 60 simbi.
