N6 high-purity reducing nickel tube

[ Material Performance ]
1. Mechanical property: excellent plasticity in annealing state, deformation resistance without cracking, argon arc welding; Creep resistance at medium temperature, stable structure at high temperature.
2. Corrosion resistance: core advantage, resistance to normal/high temperature caustic soda, molten alkali, hydrofluoric acid and fluoride media; Not applicable to strong oxidizing acids such as concentrated nitric acid.
3. Physical characteristics: good conductivity and thermal conductivity, extremely low air release in vacuum environment; With magnetism at normal temperature and oxidation resistance at high temperature superior to stainless steel.
4. Application advantages: One-piece reducing without welding seam, no welding seam corrosion perforation, suitable for high-pressure high-purity corrosive media transmission.

[ Process structure ]

1. One-piece die cold forging and reducing forming, seamless and seamless whole pipe, uniform wall thickness of transition section, no local thinning and leakage hazard.
2. The forming stress is eliminated by vacuum annealing after forming, and it is not easy to deform and crack after long-term high and low temperature cycle use.
3. Fine polishing of inner and outer walls, smooth inner wall, not prone to residual scaling of medium, high purity fluid transmission, no impurities separated out of contaminated materials.
4. The finished products are subject to hydraulic pressure test one by one+appearance and dimension inspection to eliminate cracks, uneven wall thickness and eccentric defects, and the batch consistency is stable.
