P275N Pressure Vessel Steel Plate

EN10028 P275N ipu uamea/pepa, i lalo EN tulaga faatonuina, e mafai ona tatou manatu P275N ipu uamea/pepa mo boilers ma Pressure ipu uamea.EN10028 P275N ipu uamea/pepa e mo boilers ma Pressure ipu uamea, o se normalized. ipu uʻamea ma le laupepa lea e masani ona faʻaaogaina mo le fausiaina o vaʻa mamafa ma boilers ma paipa mo vai vevela.

I lalo o le tulaga EN10028_3, ipu uʻamea P275N e tatau ona i lalo Normalized tuʻuina atu pe a processing.These uamea vasega P275NH ma P275N e masani ona faʻaaogaina i vaʻa mamafa ma boilers ese mai isi carbon_manganese fausaga ipu uamea umia i lona tetee maualuga i le mamafa i vevela uma pe a faʻaaogaina.
