Nickel and nickel alloys are non-ferrous metals with:
- High strength and toughness
- Excellent corrosion resistance
- Superior elevated temperature properties
Nickel 201 (UNS 02201)
Characteristics
- Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.
- Outstanding resistance to caustic alkalis up to and including the molten state.
- Virtually immune to inter granular attack above 315C, chlorates must be kept to a minimum.
- In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidizing salt solutions severe attack will occur.
- Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to 550C.
- Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in deaerated acid.
Applications
- Manufacture and handling of sodium hydroxide, particularly at temperature above 300C.
- Production of viscose rayon. Manufacture of soap.
- Aniline hydrochloride production and in the chlorination of aliphatic hydrocarbons such as benzene, methane and ethane.
- Manufacture of vinyl chloride monomer.
- Storage and distribution systems for phenol - immunity from any form of attack ensures absolute product purity.
- Reactors and vessels in which fluorine is generated and reacted with hydrocarbons.
Size ranges
- OD 6.0 - 89.0 mm
- WT 0.5 - 8.0 mm
- Up to 12 meters
The tubes are strictly implements the standard specification ASTM B161/ASME SB161, ASTM B163/ASME SB163, ASTM B167/ASME SB167.
