Key Features of NC22DNb / Inconel 625 Pipes & Tubes:
Superior Corrosion Resistance:
- Exceptional resistance to oxidation, pitting, crevice corrosion, and chloride stress corrosion cracking (SCC).
- Performs well in acidic, marine, and high-salinity environments (resistant to HCl, HSO, and seawater).
High-Temperature Strength & Thermal Stability:
- Maintains high mechanical strength up to 1000°C (1832°F).
- Ideal for extreme heat applications in gas turbines, reactors, and heat exchangers.
Excellent Weldability & Fabricability:
- Can be easily welded using TIG (GTAW), MIG (GMAW), and SMAW welding methods.
- No need for post-weld heat treatment, making it cost-effective and easy to manufacture.
Fatigue & Creep Resistance:
- Withstands high mechanical stress, cyclic loading, and creep deformation over long periods.
Common Applications:
- Aerospace Industry:
- Jet engine exhaust systems, heat shields, and afterburners.
- Turbine blades, combustion chambers, and structural components.
- Marine & Offshore Applications:
- Seawater piping systems, heat exchangers, and marine risers.
- Offshore oil & gas platforms, subsea equipment, and ship exhaust systems.
- Chemical & Petrochemical Industry:
- Acid processing plants, heat exchangers, and distillation columns.
- Used in HSO, HCl, HNO, and phosphoric acid environments.
- Power Generation & Nuclear Industry:
- Heat recovery steam generators (HRSG), nuclear reactors, and superheaters.
- High-pressure piping in steam and gas turbines.
