The sensor array arranged multiple sets of ring pairs along the flow direction, […]

Flange Face Corrosion in Seawater and Hydrocarbon Environment Related to Gasket Material Selection

[vc_row][vc_column][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf545d605d” show_label=”yes” el_class=” “][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf51dd605c” show_label=”yes”][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf568d605e” show_label=”yes”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text] Abstract Bolted flange joints in seawater and hydrocarbon services can be vulnerable to gasket degradation and flange face corrosion. In its document on corrosion management, the UK’s Energy Institute ranks corrosion as the second most frequent cause in initiating loss of hydrocarbon containment […]

Corrosion Resistance of 17Cr OCTG Martensitic Stainless Steels for HP/HT Wells
