Sight Glass

Sight Glass is a transparent observation component installed on storage tanks, pipelines, and equipment, which achieves visual monitoring of medium conditions through high-strength transparent materials. It is an intuitive observation accessory for industrial fluid systems.Widely used in industries such as petrochemicals, chemicals, food and pharmaceuticals, and water supply and drainage, it is compatible with storage tanks, pipelines, reaction vessels, and other equipment. It allows real-time observation of the liquid level, flow rate, flow status, and cleanliness of the medium, facilitating monitoring of working conditions and troubleshooting.

Common Types

  • Tank level sight glass: Suitable for various types of storage tanks, visually monitoring the height of the medium level inside the tank, with anti fog/anti frost design
  • Pipeline straight through sight glass: connected to industrial pipelines to observe the flow state of the medium inside the pipeline and adapt to the working conditions of pipelines with different diameters
  • Equipped with flushing mirror: With a flushing interface, the mirror can be cleaned online, suitable for media conditions containing impurities and prone to scaling
  • Stainless steel frame mirror: 304/316L stainless steel frame, corrosion-resistant and pressure resistant, suitable for corrosive and pressure bearing media scenarios

Structural Advantages & Corresponding Benefits

  1. High strength corrosion-resistant transparent substrate structure

  • Special point: The mirror surface is made of borosilicate glass/tempered glass, which is impact resistant, high and low temperature resistant, and the frame is made of stainless steel material
  • Result:The mirror surface is not easily damaged, resistant to medium corrosion, suitable for harsh industrial conditions, has a long service life, and can be observed clearly

  1. High sealing and leak proof structure

  • Special point:A corrosion-resistant sealing gasket is used between the mirror and the frame, matched with bolt compression sealing, and multiple sealing protections are provided
  • Result: No medium leakage, no external impurities infiltration, suitable for pressure/flammable and explosive medium working conditions, high sealing and safety
