Key Benefits

• Superior resistance to concentrated sodium hydroxide at high temperature, prevent caustic embrittlement
• Stable mechanical properties under continuous high temperature operation in alkali medium
• Excellent ductility, easy bending, forming and welding for alkali equipment fabrication
• Resistant to alkali stress corrosion cracking under fluctuating temperature conditions
• Long service life for continuous 24h operation of caustic soda production system

Grade Description

Gr1 Pure Nickel (N6) is the primary material for high temperature caustic soda service. It maintains outstanding corrosion resistance in hot concentrated sodium hydroxide environment and avoids caustic embrittlement failure. ASTM B161 seamless nickel pipe is widely applied in alkali chemical projects of Thailand, Indonesia and Saudi Arabia.

Product Features

Gr1 seamless pure nickel pipe is fully annealed and pickled to remove surface oxide. Each pipe passes eddy current inspection and hydrostatic pressure testing. It is commonly used for high temperature alkali delivery pipelines and heat exchanger tubes in caustic soda evaporation and concentration workshop.

Industry Applications

• Alkali chemical industry: high temperature concentrated caustic soda transfer pipeline, alkali heat exchanger tube
• Sodium hydroxide evaporation and concentration system
• Caustic soda plant revamping and new construction projects in Thailand, Indonesia and Saudi Arabia

Quality Assurance

Every batch undergoes strict inspection before shipment:

• Full dimension tolerance inspection
• Eddy‑current testing (ET)
• Hydrostatic pressure test
• Chemical composition & mechanical property testing
• Material Test Certificate (MTC) supplied for traceability

FAQ

Q: Can you cut ASTM B161 pure nickel pipe according to caustic soda process drawings?
A: Yes. Our engineering team can read alkali plant drawings and cut pure nickel pipe to required sizes.

Q: Why choose pure nickel pipe for high temperature caustic soda service?
A: Pure nickel can resist high-temperature concentrated sodium hydroxide and effectively prevent caustic embrittlement which stainless steel and titanium cannot handle.

Q: Can you provide MTC certificates for chemical plant bidding?
A: Yes, EN10204 3.1 MTC certificates can be supplied for project tender and incoming material inspection.
