Product Description
Class 900 Titanium Blind Flange | High Pressure | Polished Surface
Our Class 900 Titanium Blind Flanges are built to withstand extreme pressure environments in offshore and heavy chemical industries. These solid disks are used to block off a section of pipe or a nozzle on a vessel that is not in use, ensuring a leak-proof termination under high-stress conditions.

Engineered for High-Pressure Safety
- Forged Strength: To meet the Class 900 rating, our flanges are forged to refine the grain structure, ensuring the titanium can handle rapid pressure fluctuations without fatigue.
- Advanced Polishing Service: The fine polishing surface treatment removes microscopic surface defects that could lead to stress corrosion. This is critical for high-pressure systems where any surface irregularity can be a point of failure.
- Strict Quality Control: Every 900lb blind flange undergoes Ultrasonic Testing (UT) to guarantee there are no internal cracks or inclusions, providing 100% reliability for critical infrastructure.
Frequently Asked Questions
Q: What is the pressure limit for a Class 900 Titanium Flange?
A: A Class 900 flange is rated for approximately 2250 psi (155 bar) at ambient temperatures, depending on the specific titanium grade and operating temperature.
Q: Why is polishing recommended for high-pressure blind flanges?
A: Polishing reduces the surface roughness (Ra value), which minimizes the risk of pitting corrosion and ensures a better seal when used with high-pressure gaskets like RTJ rings.
