    Description
    Product Description
    What Is Titanium Eccentric Weld Neck Flange?
     
    Titanium Eccentric Necked Butt Weld Flange integrates an eccentric reducer structure with a necked butt weld flange (WN) into a single unit, manufactured through integral forging of titanium and precision CNC machining. The long tapered neck structure helps distribute pipeline stress, while the eccentric bore design prevents liquid accumulation at low points and gas trapping at high points in the pipeline. This makes it ideal for liquid transport, media prone to sedimentation, seawater, and acid-alkali corrosive pipelines. It addresses the common issues of gas trapping, sludge accumulation, and corrosion perforation found in standard concentric flanges, combining the high-pressure sealing advantages of butt-weld flanges with the fluid flow optimization capabilities of eccentric reducers.
     
    Pure Titanium Material and Titanium Alloy base materials naturally form a passivation protective film, providing resistance to highly corrosive media such as chloride ions, organic acids, moist chlorine gas, and brine. Lightweight and featuring high specific strength, these flanges are suitable for demanding industrial pipeline systems involving high temperatures, high pressures, and alternating loads. They are available for international export and can be customized to meet non-standard project requirements.
     
    Key Advantages
     
    • Eccentric design prevents liquid accumulation and air lock
     
    The flush, eccentric end face ensures a straight bottom surface in the pipeline, eliminating dead corners where liquid can pool. This makes it ideal for pipelines carrying media containing solid particles or prone to sedimentation, as well as continuous liquid-phase pipelines, helping to prevent cavitation and localized corrosion caused by air pockets.
    Integrally Forged for Excellent Stress Relief
     
    A long conical transition neck smoothly transfers weld stress to the titamium flange body, reducing stress concentration. It withstands high pressure, thermal shock, and cyclic pressure, making it resistant to cracking and leakage—far superior to plate flanges and slip-on flanges.
     
    • Titanium offers exceptional corrosion resistance and a long service life
     
    Gr1/Gr2 pure titanium resists seawater, chloride salts, weak acids, and moist chlorine gas; Gr7 (palladium-titanium) resists crevice corrosion; Gr12 resists reducing acids; Gr5 titanium alloy offers high strength and wear resistance, ensuring long term stability in seawater desalination, chlor-alkali, and metallurgical brine applications with low maintenance costs.
     
     
    • Precision Machining Ensures Reliable Sealing
     
    Sealing surfaces can be machined to specifications, including RF raised faces, MFM male female faces, and RJ ring joints. Surface finish meets standards, butt weld grooves are precise, welds form well without slag inclusion, and the system achieves zero leakage under high pressure.
     
    • Lightweight, Clean, and Leak Free
     
    Titanium has a low density, making it approximately 40% lighter than stainless steel; the material is stable with no heavy metal leaching, making it suitable for high-purity chemical, pharmaceutical, and food-grade clean piping systems.
     
    • Full Standard Coverage, Support for OEM Customization
     
    We manufacture Titanium Customized Parts compliant with American, Chinese, German, and Japanese standards. Non standard eccentricities, special wall thicknesses, and special pressure ratings can be engineered and manufactured upon request. We offer one-stop supply of matching Titanium Pipe Fittings made from the same material.
