4. Titanium WN flange features
Due to the transition structure of the cone neck and butt welding connection, the flange's strength and stiffness are strengthened, has good sealing performance. Its tightness is better than that of a flat welded flange. The disadvantage is that it needs to be manufactured by forgings, which consumes a lot of materials and has a large manufacturing cost. It is suitable for occasions with high pressure, high temperature, or high sealing requirements
5. Titanium pipe flange applications
Each kind of flange made of different materials has different functions. Titanium flange has excellent anti-corrosion, acid and alkali resistance, long service life, low density, and high strength in many media. It is mainly used for corrosion-resistant pipes, valves, pumps, corrosion-resistant structural parts, seawater desalination system parts, chemical heat exchangers, pump bodies, distillation towers, cooling towers, agitators, and other fluid interface accessories.
