Titanium Flange

Titanium Flanges: titanium alloy flange is often used in oil drilling, marine engineering, machinery and equipment manufacturing industry in the key pressure parts of the connection. the pure titanium flange is much used for connecting the tube ends of the petrochemical project. It is also useful in equipment exit and entrance to connect the two devices. We has rich experience in forging and machining, which makes our titanium flange products kept good quality.to meet the specific requirements of customers, we also produce titanium flange according to customer drawings.
