Heat exchangers of the "vessel in a vessel" type
Heat exchangers steel enameled type "vessel in a vessel" are designed for heat exchange with corrosive liquids.
The heat exchanger consists of a shell with a jacket and an inner vessel.
Working pressure, MPa (kgf/cm2):
in the case: 0,6 (6,0) or residual not less than 0.04 (300 mm Hg)
in a shirt: 0,6 (6,0)
Permissible wall temperature:
in the case:
• in an acidic environment - from minus 20 to plus 200°C;
• in a neutral environment - from minus 20 to plus 150°C;
• in an alkaline medium:
○ at pH=11 - from minus 20 to plus 130°C;
○ at pH=12 - from minus 20 to plus 110°C;
○ at pH=13 - from minus 20 to plus 90°C;
○ at pH=14 - from minus 20 to plus 80°C.
in a shirt: from minus 20 to plus 200°C.
