Description Of Durable CNC Lathe Machining Titanium Flanges
Durable CNC Lathe Machining Titanium Flanges are precision pipe flanges manufactured from high-quality titanium and titanium alloys through CNC lathe machining processes. The combination of durable construction, precision machining, and titanium’s exceptional properties makes these flanges ideal for demanding piping systems in corrosive and high-stress environments.
The manufacturing process begins with titanium blanks (forgings, bar stock, or plate) in grades such as GR1, GR2, GR3, GR4, GR5 (Ti-6Al-4V), GR7, GR9, or GR12. CNC lathe machining is used to turn the flange profile, face, and bore to exact dimensions, ensuring tight tolerances (±0.05mm or better), smooth sealing faces (Ra ≤1.6μm), and consistent quality. The flanges are then drilled, chamfered, and inspected to meet international standards including ASTM B381, ASME B16.5, DIN, EN, and JIS.
Titanium flanges offer a unique combination of properties: density of approximately 4.5 g/cm³ (about 60% lighter than steel), excellent corrosion resistance in seawater, chlorides, acids, and alkalis, and good mechanical strength at temperatures up to 600°C (depending on grade). The “durable” designation reflects the long service life of titanium flanges in aggressive environments, reducing maintenance and replacement costs.
Durable CNC Lathe Machining Titanium Flanges are available in multiple types including Weld Neck (WN), Slip-On (SO), Blind (BL), Threaded (TH), and Lap Joint (LJ). Sizes range from 1/2" to 24" with pressure ratings from Class 150 to Class 2500. Face types include Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). Custom sizes, tolerances, and surface finishes are available upon request.
