Chromium naturally forms a thin, adherent and very protective passive oxide layer when exposed into corrosive aqueous environment which is primarily the reason of its high resistance capabilities. When austenitic stainless is exposed to a […]

Superheated Transition Zone

[vc_row][vc_column][vc_custom_heading text=\”Heat Transition Zone\” use_theme_fonts=\”yes\”][vc_custom_heading text=\”Introduction\” font_container=\”tag:h3|text_align:left\” use_theme_fonts=\”yes\”][vc_column_text] As superheated steam enters in the transition zone of the turbine and expands into LP section, steam may cross the saturation line, in the Mollier diagram, to eventually form nucleation of moisture drops on blades and disk surfaces. Consequently, a number of physical-chemical processes will lead to

Technical efficacy must consider a deep understanding of the chemistry involved in the process and the nature of the deposit constituent to effectively determine the efficiency and selectivity of the solvents during the
