Nickel Alloy Pipes The Ultimate Solution for Seamless and Leak-Proof Piping Systems
Premium-grade nickel alloy seamless pipes are engineered for extreme industrial environments, delivering uncompromised performance where corrosion resistance, high-temperature stability, and structural strength are critical. Manufactured without weld seams—eliminating weak points like porosity or cracking—they ensure uniform durability and leak-tight reliability for long-term use.
Core Advantages
Seamless Structural Integrity: Weld-free design avoids corrosion concentration or pressure-related failures, ideal for high-pressure fluid transport.
Superior Corrosion Resistance: Nickel-based formulations (blended with Cr, Mo, Cu) resist strong acids (sulfuric/hydrochloric), seawater, alkalis, and chloride-rich media—outperforming stainless steel in harsh conditions.
High-Temp & Pressure Stability: Retains strength at temperatures up to 1,200°C and handles pressures exceeding 10,000 psi, suitable for extreme process applications.
Precision Manufacture: Rigorous hot piercing, rolling, and heat treatment (annealing/solution aging) ensure tight dimensional tolerances (±0.5% OD, ±10% wall thickness) and consistent mechanical properties.
Key Alloy Grades & Applications
Key Traits
Target Industries/Uses
Inconel 625
High-temp strength, acid resistance
Aerospace components, chemical pipelines, offshore risers
Chemical valves, marine propeller shafts, offshore platforms
Quality Assurance
Testing: Ultrasonic (UT) & eddy current (ECT) inspections for defects; hydrostatic testing (1.5x working pressure) for leak tightness.
Standards: Compliant with ASTM B163/B167, ASME BPVC Section VIII, ISO 6208, and API 5LC (oilfield).
Finishing: Pickling/passivation for oxide layer protection; polished surfaces (Ra ≤ 0.8 μm) available for hygiene-critical uses (pharmaceuticals).
Why Choose Our Nickel Alloy Seamless Pipes?
Engineered for longevity (10–20 year service life vs. 3–5 years for stainless steel), they reduce maintenance costs while ensuring compliance with strict industry regulations. Ideal for processes where material failure risks safety, downtime, or product contamination.
