In many industrial applications, standard-sized sight glass does not always meet equipment requirements. Customized or non-standard sight glass becomes essential when dealing with unique vessel designs, special operating conditions, or specific safety needs. Understanding the customization process helps users choose the right product with both reliability and precision.

The first step in customization is material selection. Depending on the working environment, borosilicate glass, quartz glass, or tempered glass may be chosen. Each material offers different advantages—borosilicate for thermal shock resistance, quartz for extreme temperature and chemical stability, and tempered glass for mechanical strength and safety.

Next comes cutting and shaping. Advanced CNC cutting machines and waterjet technology allow precise fabrication of circular, square, or irregular shapes. The dimensions are tailored to customer specifications, ensuring a perfect fit with equipment flanges or housings. For thicker applications, multi-layer lamination may also be applied to increase durability.

Edge processing follows to enhance both safety and performance. Grinding and polishing the edges prevent stress concentration and reduce the risk of cracking during installation or operation. Chamfered edges can also improve sealing effectiveness when paired with gaskets.

Finally, surface treatments may be applied depending on functional needs. Anti-reflective coatings improve optical clarity, anti-fog layers maintain visibility in humid environments, and protective coatings enhance resistance against corrosion or abrasion. Each finishing step ensures that the customized sight glass is optimized for its intended application.

In conclusion, customizing non-standard sight glass involves a combination of precise material choice, advanced cutting and shaping, careful edge processing, and specialized surface treatments. By following these steps, manufacturers deliver reliable, high-performance solutions tailored to the unique demands of industrial equipment.
