Lumiglas Circular Sightglass Weld-On, DIN 28120 PN16, 316L, 321, PTFE, Borosilicate, Size DN50
Weld-on circular sightglass 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. The kit includes one Weld pad made from 316L stainless steel, one Cover flange made from 321 stainless, one toughened borosilicate disc, one seal gasket made from PTFE (Teflon), one cushion gasket made from Klinger(R) C-4400, eight mounting studs and nuts made from 304 (A2) stainless steel. 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, which has greater strength. The combination of 316L for weld pad and 321 for the clamp flange gives this kit the most optimum balance of strength and corrosion resistance.
This kit is suitable for clean room applications, semiconductor, pharmaceutical or food processing applications with requirements for sanitary use.
After welding the ferrule (weld pad) the sightglass disc has a permanent dedicated location on the pressure vessel. Cover flange, window, seals and mounting hardware can be replaced during scheduled service intervals or as needed. Sightglass disc and the gaskets must be replaced whenever the assembly is taken apart.
