Stainless Steel Welded Pressure vessel Sight Glass

The Welding Flange Sight Window is designed to be welded directly onto a tank or other liquid-containing vessel, and allows visual observation of level, color, or clarity of a liquid in a vessel or tank at a low initial cost.
Standard Welding Flange Sight Window units are furnished with a flat bottom. Upon request, the unit can be machined with a cylindrical radius to match the contour of the vessel. The Sight Glass are available in single or multiple section types.
Our oblong units are designed for pressures up to 150psi and temperatures up to 450°F, and various materials of construction are available to meet your process needs.
