Product DescriptionLumistar Threaded Sight Glass MV | High-Temperature & Pressure Resistant Borosilicate Glass | ISO 9001 CertifiedSolve Industrial Leakage & Durability Challenges with Precision-Engineered Sight GlassesIndustrial operators in chemical processing, pharmaceutical manufacturing, and oil/gas sectors face critical challenges in monitoring equipment under extreme conditions: Leakage Risks: Poor sealing at threaded joints under thermal cycling. Material Degradation: Standard glass cracks under high pressure (>10 bar) or rapid temperature shifts (-60°C to 450°C). Customization Gaps: Limited suppliers offering scalable thread standards (DIN/ANSI/JIS) . Lumistar Threaded Sight Glass MV delivers a leak-proof, high-performance solution tailored for harsh environments: Key Features & Solutions1. Zero-Leakage Threaded DesignPatented Triple-Seal Thread Technology (TST?) ensures airtight performance even with 500+ thermal cycles. Compatible with DIN 2999, ANSI B1.20.1 threads – reduces installation errors by 40%. 2. Borosilicate Glass 3.3 – Superior Material Science Withstands -60°C to 450°C and 15 bar pressure (tested per ASTM E438). 30% higher corrosion resistance vs. soda-lime glass in acidic/alkaline media (pH 1-14). 3. Customization Supports DN15-DN200 sizes, tempered glass options, and hybrid metal/glass designs. ApplicationsFor viewing of internals of pressure vessels, silos, stirred vesselsseparators, pipelines and other normally enclosed systems.Continuous monitoring for leakage is possible with externallyfitted pressure gauge.Key ConfigurationsConnection flange: PN10/16 The design of the supporting spacer ring ensures that each ofthe two glasses discs is able to withstand the maximum ratedoperating pressure and max. permissible temperatureindependently of the other.Combination: with Lumistar spotlights for explosion-proof and non-explosion-proof areas. Matching threaded apertures are provided on the flange cover for fixing the spotlights.Operating environment: pressure resistance:10bar (higher pressure resistance can be customized)Operating temperature: 150℃ with toughened Sodalime to DlN 8902 280℃ with borosilicate glass to DIN7080 (other higher grades of high-temperature resistant glass can be customized.Lumistar Threaded sight glass MV Product PerformanceApplication:Butt-weld sightglass fitting with a threaded cover nut. Sightport for viewing into process vessels, silos, mixers, separators, pipelines, and other usually closed containers. Particularly suitable for pharmaceutics, food and beverage processing, e.g. breweries, dairies etc.General:Sightglass fittings specific to DIN 11851 (dairy standard fittings) with see-through circular glasses. Threaded nozzles have weld necks.Combination:This sightglass unit can be combined with the Lumiglas luminaires for use in non hazardous areas. Window wipers, type SW1 can be fitted to sizes DN 65 and larger. Combination of luminaire plus wiper can be fitted to size DN 125.Operating ConditionsPressure: up to 150 psi (depending on size), vacuumTemperature: max. 220°C (see temperature diagram) based on seal ringParts & materials: (The drawing is below)Itempartmaterial1Threaded cover nutStainless steel type 3042Cushion gasketNon-Asbestos3Sightglass discSoda lime glass, tempered for max temp150°C; or borosilicate glass, tempered for max. temp280°C4D-ring sealViton, PTFE, Buna, silicone (max. 250°C)5Weld neck nozzleStainless steel type: 316 L, 304; ASME material onlyavailable upon request6Vessel wallAssembly: After welding nozzle (5) into the vessel wall (6), fit O-ring seal (4), glass disc (3)and gasket (2) as shown in the drawing on the right.
