Product Description Hastelloy Industrial Tubular DIN Welding Explosion Proof Flow Sight Indicator with Light Flange GlassA Hastelloy sanitary sight glass is a highly corrosion-resistant, transparent viewing device designed for installation in pipelines or tanks to monitor fluid flow, clarity, and process conditions in real time. It is widely used in hygienic and demanding industries such as chemical, pharmaceutical, biotechnology, and high-purity fluid systems. The body is made from durable Hastelloy, featuring a high-strength tempered glass window for safety, durability, and pressure resistance.Working PrincipleThe Hastelloy sanitary sight glass works by allowing visual observation of fluids through a transparent window integrated into a pipeline or tank. First, the fluid flows through the device. Second, the glass window, sealed within a Hastelloy frame, provides a clear and unobstructed view of the medium. Third, any changes in color, clarity, bubbles, or contamination can be detected instantly and accurately. The sight glass is designed to withstand high pressure and temperature, ensuring safe operation, and some models include a built-in 24V DC LED light to enhance visibility in low-light conditions.SpecificationsSize Range: DN25-DN150 / 1"-6"Connection Type: Quick-release, Thread, Welding, FlangeMaterial: Hastelloy C-22 / C-276Glass Type: Tempered glass, Borosilicate glassPressure Range: 0-10 bar (customizable for higher pressure)Temperature Range: -20°C to 200°C (depending on glass and seal material)Seal Material: EPDM, PTFE, SiliconeOptional Light: 24V DC LED sight lightAdvantages & Service3-year quality guaranteeISO 9001, FDA, SGS certified materialsFast delivery in 7-10 days for urgent ordersOver 20 years of exporting experience, ensuring customization is easy and reliable Tubular Sight GlassUnion Type Sight Glass (DIN 11851/SMS)Flange-Type Viewing Sight Glass with LEDSight Glass with WiperSpecifications/ SizesSizes 1"-4" (DN25-DN100); working pressure typically up to ~10 bar (150 psi)DN40-DN80 typical (up to DN150 available); surface finish ≤0.8 μm RaFlanged mount (ANSI/DIN); pressure per nozzle classDN50-DN150 common; pressure up to ~10 bar; temp up to ~150 °C; manual wiper clears viewing pane during operation.Working PrinciplesTransparent borosilicate tube installed inline for continuous visual inspection of flow.Threaded union clamps glass disc between male/female ends for sanitary pipelines.Flanged sight window on vessel/nozzle, paired with LED light for illumination.Rotary or reciprocating external wiper sweeps inner glass face to remove condensate/films.Key FeaturesUnobstructed sightline, easy CIP/SIP (depending on model), clamp or union ends.Hygienic union connection; quick disassembly; optional wiper or light.Integrated or bolt-on LED (non-Ex or Ex-rated); wiper optional; improved visibility in dark vessels.Maintains visibility with foaming/viscous fluids; retrofit kits available; optional light port.Suitable ApplicationUnobstructed sightline, easy CIP/SIP (depending on model), clamp or union ends.Dairy standards lines, fermenters, filters, reactors.Tanks, reactors, dark or foaming processes; ATEX areas with Ex-rated lights.Brewing, sauces, syrups, crystallizers, emulsions-anywhere fouling blocks view.
