Classification
-
Classification by Forming Process
-
Classification by Composition and Properties•Pure Nickel Pipes (N4/N6/N8): High Ni+Co content, excellent electrical and thermal conductivity, strong basic corrosion resistance, suitable for conventional environments such as electronic power and general industry.
•Nickel Alloy Pipes (N02200/N02201/N04400/N05500, etc.): Better corrosion resistance, higher high-temperature stability and stronger pressure resistance, suitable for complex and harsh scenarios such as chemical industry, high-end equipment and extreme environments.
Core Properties
- Excellent Electrical and Thermal Conductivity: Conductivity is about 60% of copper, with good thermal conductivity, which can efficiently realize heat exchange and conductive functions during fluid transportation, ensuring equipment operation efficiency.
- Super Corrosion Resistance: High stability in environments such as neutral salt solutions, organic acids, weak alkalis, seawater, high-temperature flue gas, and acid-base chemical media. The passivation film formed on the surface can effectively resist corrosion and greatly extend the service life of the product.
- Wide Temperature Range Adaptability: Melting point up to 1455℃, maintaining stable mechanical properties and electrical properties in the range of -200℃ to 800℃, no embrittlement at low temperature and no softening at high temperature, adapting to multiple extreme temperature working conditions.
- Excellent Mechanical and Pressure Resistance: Uniform pipe wall structure, high tensile strength and yield strength, good pressure resistance, can withstand medium and high pressure fluid transportation pressure, and operate safely and stably.
- Excellent Processability: Can easily realize various precision processing such as cutting, welding, flange connection and beveling. After vacuum annealing, internal stress is eliminated, and performance is stable after forming, adapting to different installation requirements.
