Welding neck titanium flange

[ Material Performance ]
1. Mechanical property: lightweight, with density far lower than that of carbon steel and stainless steel; Good annealing plasticity, good fusion with argon arc welding of titanium tube, strong bending moment and vibration resistance of long neck structure.
2. Corrosion resistance: stable passive film is generated on the surface, and it is resistant to seawater, salt water, dilute acid and alkali, wet chlorine, and no pitting corrosion and stress corrosion in long-term chloride ion environment.
3. Physical characteristics: non-magnetic, good toughness at low temperature; The material is pure and free of heavy metal precipitation, meeting the transportation requirements of pharmaceutical and high-purity media.
4. Application advantages: the welding seam of butt welding structure is far away from the sealing surface, the medium is not easy to erode the sealing area, and the high pressure working condition is not easy to leak.

[ Process structure ]

1. It is integrally forged into one structure, without splicing and delamination. The flange plate is seamless with the long neck, and its pressure bearing and impact resistance are superior to the plate flat welding flange.
2. Tapered gradual change neck section can buffer thermal expansion and cold contraction stress of pipeline, reduce the risk of weld fatigue cracking, and it is suitable for cold and hot alternate pipeline.
3. Precise turning of welding groove, close connection with titanium seamless pipe, beautiful welding formation and consistent weld corrosion resistance.
4. The finished product is subject to 100% visual inspection, with precise flatness of sealing surface, stable sealing with gasket and no leakage during ex-factory pressure test.
