I-P265GH Pressure Vessel Steel Plate

Insimbi ye-P265GH - Ingazweli Ukushisa & Non-Alloy

Iyini i-P265GH?
I-Grade P265GH yizinsimbi ze-Heat Resistant Pressure Vessel ezichazwe ohlelweni lwe-EN 10028. Yinsimbi engeyona i-alloy. Izinto ezisetshenziswayo zenzelwe ukusetshenziswa kwezinga lokushisa eliphezulu. Ngakho-ke isetshenziswa kakhulu ekusetshenzisweni kokushisa okuphezulu emkhakheni kawoyela negesi, izimboni zokucubungula amakhemikhali kanye nemikhakha ye-petrochemical.

Kuyinto eyinhloko yokwakha yama-boilers nemikhumbi enomfutho. Ijwayeleke ngokuyigcina iphikisana nezinga lokushisa lika-890 kuya ku-950 ° C ngaphandle kokubamba; ukushisa kudluliselwa ngokuqina kwepuleti.

Yini i-EN 10028?
I-P265GH ikhonjwa ku-EN 10028 ejwayelekile. Kuyindinganiso ebalulekile yase-Europe "yemikhiqizo eyisicaba eyenziwe ngezinsimbi ngenhloso yokucindezela". Ngaphezu kwalokho, indinganiso ihlanganisa "Izinsimbi ezingezona i-alloy kanye ne-alloy ezinezakhiwo ezishiwo zokushisa eziphakeme". Izinga lashicilelwa ngonyaka ka-2009.

Kungani i-P265GH ibizwa nge-A516 grade 60 Steel?
I-P265GH ingxubevange yegama elisezingeni laseYurophu, elibizwa nangokuthi i-A516 grade 60 kumazinga we-ASME/ASTM. Abakhiqizi abaningi bathi bathobela kokubili ukucaciswa kwe-EN 10028 kanye ne-ASME/ASTM impahla yensimbi engu-A516 grade 60.

Amagama
I-GH - ilungele ukusetshenziswa emazingeni okushisa aphakeme okusebenza
NH - isevisi yokushisa okuphakathi nendawo kuya phezulu
I-NL1 - ilungele ukusetshenziswa emazingeni okushisa aphansi
I-NL2 – ilungele ukusetshenziswa emazingeni okushisa aphansi ikakhulukazi
