Lumiglas Weld-On Circular Sightglass, Stainless Steel Housing, ASME B16.5
Weld-on circular sight glass for a quick observation inside pressure vessels, silos, pipelines, oil tanks, mixers separators. This sightglass fitting comes standard with all seals and mounting hardware included. Standard window material is tempered borosilicate. Stronger Metaglas(R) window is optional. The kit includes one Weld pad made from 316L stainless steel, one Cover flange, one toughened borosilicate disc, one seal gasket, one cushion gasket made from Klinger(R) C-4400, eight mounting studs and nuts. The Weld pad is flat on the bottom and has a weld prep chamfer ready to be welded to a flat process wall. Curvature can be machined in as needed to match non-flat vessel walls. The weld pad made from 316L has better overall corrosion resistance than 321 or RST 37.2, which have greater strength. The combination of 316L for the weld pad and 321 stainless steel gives this kit the most optimum balance of strength and corrosion resistance.
