I-P275N Pressure Vessel Steel Plate

EN10028 P275N steel plate/ishidi, ngaphansi kwezinga le-EN, singabheka i-P275N steel plate/sheet for boilers and Pressure Vessels steels.EN10028 P275N ipuleti lensimbi/ishidi elokubhayela nezinsimbi ze-Pressure Vessels, liyinto evamile. ipuleti lensimbi kanye neshidi elisetshenziselwa kakhulu ukwakha imikhumbi yokucindezela kanye nama-boilers namapayipi oketshezi olushisayo.

Ngaphansi kwe-EN10028_3 ejwayelekile, ipuleti lensimbi P275N lizoba ngaphansi kwesimo sokulethwa Esijwayelekile lapho sicutshungulwa.Lezi zinhlobo zensimbi ze-P275NH kanye ne-P275N ezisetshenziswa kakhulu emikhunjini yokucindezela kanye namabhayela ahlukile kwamanye amapuleti ensimbi e-carbon_manganese aphethe ukumelana kwawo okuphezulu nokucindezela kuwo wonke amazinga okushisa lapho esetshenziswa.
