Frequently Asked Questions
What industries use Sight Glass?
LibertyCES has documented Sight Glass specified across 2 sector applications, including Chemical Processing and Chemical Storage & Tank Farm.
How is Sight Glass used in Chemical Processing?
Sight Glass is specified for Chemical Processing applications — examples include Richter PSG (standard flanged, DN25-DN150, 16 bar, -60°C to +180°C / -75°F to +360°F, DIN 3237 part 2, integrated drip lip, individually exchangeable cover flanges, borosilicate panes to DIN 7080; PSG/F in PFA, PSG/F-L antistatic PFA), Richter TSG (standard flanged, DN25-DN80, 16 bar, -60°C to +180°C; TSG/F, TSG/F-L), Richter SGS (cylindrical, DN15-DN100, 6 bar, -60°C to +150°C, viewing from all sides, cavity-free design option; SGS/F, SGS/F-L). This is well-documented in LibertyCES's field data.
