Titanium Flanges, produced under stringent conditions and shipped to the Middle Eastern and South East Asian countries. Our ASME SB363 Titanium Gr.1 Gr.2 Weld Neck Flanges with a long tapered hub facilitating various strong, water-tight connections to several severe conditions, like the chemical and marine industry. Not only are they immune to erosion, shock and salt water, WNR 3.7025 Titanium Threaded Flanges are most appropriate for small diameter size pipes, and have resistance to both reducing and oxidising environments, also with those that contain chlorides, like chloride production and desalination industry.

Our UNS R50400 Titanium Orifice Flanges help in measuring liquids and gases in the pharmaceutical and gas distribution system.
