FAQs of Double Sight Glass:

Q: How is a Double Sight Glass installed in a pipeline?

A: The Double Sight Glass can be mounted in either horizontal or vertical pipelines, using flanged connections (ANSI, DIN, BS) or threaded ends according to your pipe specification. Ensure the gasket is properly seated and flanges or threads are tightened as per industry standards for leak-proof operation.

Q: What benefits does borosilicate glass provide for this sight glass?

A: Borosilicate glass offers high mechanical and thermal strength, excellent chemical resistance, and outstanding transparency (over 85%). This makes it ideal for harsh industrial environments, enabling clear and reliable observation while withstanding high temperature (up to 280C) and pressure (up to 16 bar).

Q: When should the sight glass be cleaned or replaced?

A: Routine inspection should be performed according to your plants maintenance schedule. Cleaning is recommended if visual clarity decreases or contamination is observed. If cracks, scratches, or damage appear on the glass or leakage occurs, immediate replacement is advisable to maintain system integrity and safety.

Q: Where is the Double Sight Glass typically used?

A: This sight glass is widely applied in pharmaceutical, chemical, food processing, dairy, and petrochemical plantsanywhere process observation is necessary. Its ability to handle corrosive fluids and high process temperatures makes it suitable for various industrial pipeline installations.

Q: What is the process for maintaining and replacing the Double Sight Glass?

A: To maintain, simply unbolt the flange or unscrew the threaded connection, remove the glass, clean both the glass and housing, and reseat the gasket. If replacing, insert a new borosilicate glass plate and reassemble using the PTFE gasket, ensuring a secure, tight fit for continued leak-proof performance.

Q: How does the structure ensure leak proof and corrosion resistance?

A: The combination of double window bolted flange structure, PTFE/gasket seals, and high-grade stainless steel 304/316 housing ensures effective sealing, resisting both leaks and corrosion even under chemically aggressive or high-temperature process conditions.

Q: What are the primary usage and benefits of the Double Sight Glass?

A: Its main use is to facilitate safe, real-time observation of fluids in industrial processes. The benefits include improved process monitoring, simplified maintenance, superior durability, and enhanced safety due to its robust, transparent, and easy-to-clean design.
