Titanium Slip-on Flange

The Titanium Slip-on Flange is a widely used pipe flange type designed to be slipped over the pipe and then welded both inside and outside to provide strength and prevent leakage. Made from high-grade titanium or titanium alloy, this flange is ideal for corrosive environments such as chemical processing, marine systems, and high-performance aerospace or medical applications.
We manufacture titanium slip-on flanges according to international standards such as ASME B16.5, DIN, EN1092-1, JIS, and GB/T, with materials available in Gr1, Gr2, Gr5 (Ti-6Al-4V), Gr7, Gr9, Gr12, and others upon request.
