Precision polished pure nickel seamless round pipe

  • Material: N200 industrial pure nickel (N6, UNS N02200)
  • Executive standard: GB/T 2882, ASTM B167
  • Specification: outer diameter Φ 6~108mm, wall thickness 1~10mm, can be cut according to the required length
  • Supply status: vacuum annealed soft state, precision mirror polishing of inner and outer walls
  • Product Description:It is made of N200 (N6) pure nickel seamless pipe through deep machining. The inner and outer walls are precision mirror polished, and the inner wall is smooth without dead corner. It is resistant to
[ Material Performance ]
1. Mechanical property: good plasticity after annealing, bendable coil, argon arc welding, not easy to crack during processing;
2. Corrosion resistance: resistant to concentrated alkali, molten alkali and hydrofluoric acid, not applicable to strong oxidizing nitric acid;
3. Physical and chemical characteristics: stable thermal conductivity, high temperature oxidation resistance, extremely low gas release in vacuum environment;
4. Application advantages: polishing the inner wall is not easy to deposit dirt and retain impurities, ensuring clean medium and less pipeline resistance.


[ Process structure ]

1. Seamless extrusion and cold-rolled forming, dense pipe wall structure, no porosity and interlayer, no weld corrosion and leakage;
2. Multi-level precision polishing treatment of inner and outer walls, low surface roughness and uniform finish;
3. Vacuum stress-relief annealing to eliminate cold working stress, and the bend is not easy to rebound and crack;
4. The finished products shall be subject to hydraulic pressure test one by one, NDT, clean package and free of oil stain oxide layer.


[ Application field ]

1. Fluorine chemical industry, chlor-alkali: high-purity fluoride, caustic soda clean transmission pipeline;
2. New energy hydrometallurgy: electrolyte precision cooling circulating pipeline;
3. Electronic vacuum industry: special high-purity gas, vacuum furnace circulating pipe materials;
4. Precision heat exchange equipment: Polished nickel coil heat exchanger with strong alkali medium;
5. Corrosion-resistant clean pipeline for laboratory high-purity reagent delivery.
