Rectangular Glasses | Encole

Rectangular Glasses

Obround and rectangular sight windows with a weld-on base pad. In typical applications the base flange is welded to the process vessel, and the rest of the sight window components mount into that base flange. Glass is sandwiched between a sealing gasket and a cushion gasket. Cover flange is bolted to the base flange holding the assembly together. Gaskets, mounting hardware and the glass can be replaced during scheduled service intervals or as needed. Choose from obround or rectangular sight glasses. Rectangular and obround sightglass fittings are common for viewing inside pipelines, pressure vessels, liquid tanks. Primarily used for liquid level observation.

Obround Weld Pad Gauge Sight Glasses

Obround Weld Pad Gauge Sight Glasses
Obround sight glasses designed for visual inspection of levels inside a tank or a pipeline. The sight glass base flange is a weld pad designed to be welded directly to the pressure vessel. The glass is sandwiched between a sealing gasket and a cushion gasket held in place with a clamping flange. The cushion gasket is made from a material harder than the sealing gasket to insure proper compression. Glass is clear, made from tempered borosilicate. These windows are suitable for the ASME pressure code requirements.
