Comprehensive Range of Titanium Flange Types
Almerca Titanium Industry Co., Ltd. manufactures all primary industrial flange configurations for specialized piping projects:
- Weld Neck Flanges (WN): Designed with a tapered hub to minimize stress concentrations; ideal for cyclic loading, extreme pressures, and elevated temperatures.
- Slip-On Flanges (SO): Fitted over pipe ends and welded internally and externally; easy to align and economical for medium-pressure piping.
- Blind Flanges (BL): Solid disk forgings used to seal piping ends, pressure vessel nozzles, and inspection ports.
- Socket Weld Flanges (SW): Feature an internal recess for insertion of small-diameter pipes; suitable for high-pressure, small-bore piping lines.

Frequently Asked Questions (FAQ)
Q: What is a titanium flange used for?
A: A titanium flange creates a detachable, leak-proof joint connecting pipes, valves, pumps, pressure vessels, heat exchangers, and processing equipment. Titanium flanges offer outstanding corrosion resistance in chlorinated and marine environments.
Q: What are the most common titanium flange grades?
A: Commercially pure titanium Grade 2 is the most widely specified for industrial chemical systems due to its optimal balance of strength and corrosion resistance. Grade 5 (Ti-6Al-4V) is preferred for high-strength aerospace applications, while Grade 7 provides superior performance in severe reducing acids.
