Polished Gr2 Titanium Weld Neck Flange HG20592
Polished Gr2 Titanium Weld Neck Flange HG20592
The polishing surfaced Grade 2 titanium welding slip pipe flange is a high performance component built for secure piping connections. Made from Grade 2 titanium, it combines strength and low weight with strong corrosion resistance, and its polished finish both improves appearance and helps resist corrosion for easier maintenance. The weld neck design allows easy alignment and installation for a reliable joint, and the same flange is also offered in carbon steel when a different material is required. It suits marine, chemical and industrial piping systems where durability and finish matter.
