Nickel Protective Tube
Nickel protection tube is a protective device made of nickel or nickel alloy, usually used to protect internal structures or equipment from external environmental influences. Nickel materials have excellent corrosion resistance, high temperature resistance, and mechanical properties, so nickel protective pipes are often used in industrial equipment, chemical treatment equipment, oil and gas industries, and other fields in harsh environments.

product key technologies
Material purity control, welding and surface treatment
High purity nickel tubes (such as 99.999% nickel content) need to be controlled for impurities (such as carbon ≤ 0.02%, sulfur ≤ 0.005%) through processes such as vacuum melting and electrochemical refining to ensure material stability.
Nickel based alloy tubes (such as NS112, C-276) are optimized for corrosion resistance by adding elements such as chromium (19-23%) and molybdenum.
TIG welding combined with specialized welding wire (such as ErCuNi), strictly controlling heat input to prevent thermal cracks and porosity;
Chemical nickel plating (thickness 10-50 μ m) enhances surface hardness (HRC 58-62) and corrosion resistance.
Forming and processing
Hot processing: The nickel tube blank is initially formed by extrusion/hot rolling (1400-1600 ℃) to ensure high temperature strength;
Cold processing: Cold drawing/cold rolling improves accuracy (tolerance ± 0.05mm), suitable for thin-walled precision pipe fittings;
Seamless process: Perforated oblique rolling technology is used to produce seamless pipes, avoiding weak areas in the weld seam.
Application Fields
High temperature and harsh environment
Thermocouple protection tube: Nickel based alloy (containing 15-20% Cr) is resistant to sulfur-containing gas corrosion, ensuring temperature monitoring accuracy;
Aircraft engine: Inconel series seamless pipes can withstand 1400 ℃ gas flushing.
Strong corrosive medium
Chemical equipment: N6 pure nickel tube for transporting concentrated alkali solution, with a threefold increase in lifespan;
Ocean engineering: Copper nickel alloy pipes (such as C70600) are resistant to seawater erosion and are used for seawater pipelines.
Precision Industry
Electronic components: N2 nickel tube manufacturing vacuum devices, MEMS sensors, stable conductivity;
Energy system: High purity nickel tubes enhance the cycling life of lithium battery electrodes.
Nickel protective tubes play an irreplaceable role in the industrial field due to their excellent high temperature resistance, corrosion resistance, and stable mechanical properties.
From chemical equipment to aerospace, from precision electronics to energy systems, these metal fittings safeguard the normal operation of critical equipment with reliable quality.
Their widespread application not only reflects the unique advantages of nickel materials, but also demonstrates the ultimate pursuit of material performance by modern industry.
