Engineering Description
Single Window Sight Glass provides direct inline visual verification of media flow clarity colour and contamination.
Double Window Sight Glass incorporates dual opposing glass discs allowing enhanced viewing angle and improved safety in higher pressure or elevated temperature services. Straight bore construction ensures minimal pressure loss. Bolted cover arrangement enables glass replacement without pipeline alteration. Optional vent drain and protective mica shield available for thermal duty.

Applications
Installed in refinery process headers, petrochemical transfer lines, thermal power condensate systems, desalination skids, steel plant circuits and district cooling networks. Suitable for water hydrocarbon steam condensate and chemical process fluids.
