Ipleyiti yentsimbi yeP265GH yoxinzelelo

Intsimbi ye-P265GH-Ukumelana nobushushu kunye ne-Non-Alloy

Yintoni iP265GH?
IBakala P265GH yi-Heat Resistant Pressure Vessel Steels echazwe kwinkqubo ye-EN 10028. Yintsimbi engeyiyo ialloyi. Izinto eziphathekayo zenzelwe izicelo zokushisa okuphezulu. Ke ngoko isetyenziswa kakhulu kwizicelo zobushushu obuphezulu kwicandelo leoli negesi, kumashishini okwenziwa kweekhemikhali kunye namacandelo epetrochemical.

Yeyona nto iphambili yokwenza iibhoyili kunye neenqanawa ezinoxinzelelo. Iqhelekile ngokuyigcina ngokubhekiselele kubushushu be-890 ukuya kwi-950 ° C ngaphandle kokubamba; ukufudumeza kugqithiswa ngobunzima beplate.

Yintoni i-EN 10028?
I-P265GH ichongiwe kumgangatho we-EN 10028. Ingumgangatho wezinto zaseYurophu "Iimveliso zeFlat ezenziwe ngeentsimbi ngeenjongo zoxinzelelo". Ngaphezu koko umgangatho ugubungela "Iintsimbi ze-non-alloy kunye ne-alloy ezineempawu zokushisa eziphakanyisiweyo". Umgangatho wapapashwa ngonyaka ka-2009.

Kutheni le nto i-P265GH ibizwa ngokuba yi-A516 ibakala lama-60 ngentsimbi?
I-P265GH yi-alloy yobizo kumgangatho waseYurophu, ikwabizwa ngokuba yi-A516 grade 60 kwimigangatho ye-ASME/ASTM. Abavelisi abaninzi bathi bayahambelana neenkcukacha ze-EN 10028 kunye ne-ASME / ASTM izinto ze-A516 ze-60 zensimbi.

Isigama
I-GH - ilungele ukusetyenziswa kumaqondo obushushu aphakamileyo okusebenza
NH - kwinkonzo yobushushu obuphakathi ukuya phezulu
I-NL1 - ilungele ukusetyenziswa kumaqondo obushushu aphantsi
I-NL2 – ilungele ukusetyenziswa kumaqondo obushushu aphantsi ngakumbi
