About Sight glass/ View glass

Material Selection BodyFlanges Typically ASTM A182 F316316L or F304 SS316L is preferred for its superior resistance to pitting and intergranular corrosion Lining PTFE Teflon or PFA Note PFA is often preferred for molded linings because it has better meltprocessability and lower permeability than standard PTFE Lining Thickness Usually ranges from 3mm to 5mm depending on the pipe size Glass Disk Borosilicate glass for thermal shock resistance or Quartz for hightemperature applications CushionsGaskets Usually PTFE or Graphite to protect the glass from the metal cover 2 Design Standards Pressure Flange Rating Commonly ANSIASME B165 Class 150 or Class 300 FacetoFace Often follows manufacturer standards or DINANSI piping dimensions Pressure Rating Typically limited by the glass thickness and the linings integrity at temperature Standard units often handle up to 1016 bar but this drops as temperature increases

Robust Construction & Versatile Installation

Made with borosilicate toughened glass and a stainless steel frame, this sight glass is designed to withstand harsh industrial environments.

This sight glass is available in various shapes (round, rectangular, or custom) and accommodates glass sizes up to 200mm in diameter. It's compatible with standard and custom pressure ratings, different seal materials, and threaded connections (BSP, NPT). Suitable for CIP/SIP cleaning, it supports use with aggressive media in chemical, pharmaceutical, and food processing industries.

FAQ's of Sight glass/ View glass:

Q: How is the sight glass installed and what mounting options are available?

A: The sight glass can be installed either horizontally or vertically, depending on your application. Mounting options include flanged, screwed (threaded), or welded ends, making it versatile for different pipework and vessel configurations. Customization for BSP or NPT threading is also available to match specific system requirements.

Q: What types of media can this sight glass safely handle?

A: This sight glass is compatible with a broad range of liquids, including acidic, alkaline, and corrosive media, thanks to its borosilicate glass and stainless steel construction. Different seal materials (PTFE, Neoprene, EPDM, Viton) can be selected based on the process fluid to ensure chemical resistance and operational safety.

Q: When should I consider using a double window or a protective grid?

A: A double window configuration is advisable for applications requiring enhanced safety or when handling particularly hazardous processes. The optional protective guard, available in stainless steel or polycarbonate, shields the glass from accidental impacts and ensures operator safety during routine inspections.

Q: Where can this sight glass be used within an industrial setup?

A: You can use this sight glass for direct visual observation of liquid levels and flows in industrial pipelines, tanks, or process vessels. Its robust design suits industries such as chemical processing, pharmaceuticals, food and beverage, water treatment, and other sectors requiring real-time inspection of fluids.

Q: What benefits does the dual gasket/dual sealing leak-proof design offer?

A: The dual gasket or dual sealing system ensures optimal tightness, minimizing the risk of leaks even under high pressure (up to PN16 and custom ratings). This feature boosts the reliability and safety of your process operations, especially when managing corrosive, high-temperature, or hazardous fluids.

Q: How is the cleaning and maintenance process facilitated with this sight glass?

A: The sight glass is engineered for ease of cleaning, compatible with CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocols. This design lowers downtime, supports hygienic process conditions, and suits industries where cleanliness and contamination prevention are critical, such as pharmaceuticals and food processing.

Q: What customization options are available for size and specification?

A: Size and specifications are highly customizable-glass diameter can range from 25mm to 200mm, thickness up to 12mm depending on application, and frame shapes can be round, rectangular, or tailored to your needs. Pressure ratings, seal types, and end connections can be specified as per your process requirements.
