Titanium Blind Flange

The Titanium Blind Flange is a solid disk used to block off a pipeline or create a stop in a piping system. It is commonly installed at the end of piping systems or on pressure vessel openings that are not in use. Titanium blind flanges are known for their superior corrosion resistance, light weight, and high strength, making them ideal for chemical processing, marine engineering, and high-performance applications in aerospace and medical industries.
Our titanium blind flanges are produced in compliance with international standards such as ASME B16.5, ANSI, DIN, EN1092-1, JIS, and GB/T, and are available in grades Gr1, Gr2, Gr5, Gr7, Gr9, and Gr12.
