Case Study: Engineering a 30 MPA Custom Sintered Sight Glass for a German University Laboratory

At Wenzhou Borlan Fluid Machinery, we thrive on engineering challenges. While we manufacture a wide range of standard sanitary valves and fittings, our true strength lies in our custom OEM/ODM capabilities.

Recently, we were approached by a prestigious university laboratory in Germany with a highly demanding request: they needed a sight glass capable of withstanding extreme high-pressure conditions for their advanced fluid research.

Here is how Borlan delivered a flawless solution.

⚠️ The Challenge: Extreme Pressure in a Research Environment

The German laboratory required a sight glass to monitor fluid behavior under extreme stress. The technical requirements were strict:

• Maximum Working Pressure: 30 MPA (Approximately 4350 PSI).
• Connection Type: Precision NPT threading for secure, leak-proof integration into their existing test rigs.
• Safety & Durability: Absolute reliability, as any failure at 30 MPA in a laboratory setting could be catastrophic.

Standard tempered sight glasses are simply not designed to handle this level of pressure. A specialized, heavy-duty solution was required.

💡 The Borlan Solution: Advanced Sintered Sight Glass Technology

To meet and exceed the client’s expectations, Borlan’s engineering team designed a Custom Sintered Sight Glass.

Unlike standard sight glasses where the glass is mechanically sealed with gaskets, a sintered sight glass involves fusing the glass directly to the metal housing at extremely high temperatures. This creates a single, unified component.

Key Advantages of Our Sintered Solution:

1. Unmatched Pressure Resistance: The metal-to-glass fusion eliminates weak points, allowing the unit to comfortably handle the 30 MPA (4350 PSI) requirement without risk of shattering or blowout.
2. Superior Safety: In the rare event of extreme overpressure, sintered glass is designed to crack safely rather than shatter explosively, protecting laboratory personnel.
3. Precision NPT Connection: We machined the housing with high-precision NPT threads, ensuring a perfect, airtight fit with the German lab’s equipment.
4. Corrosion Resistance: Constructed with premium-grade stainless steel to withstand harsh chemical environments often found in research facilities.
