Description

Customizable Heat-Resistant Nickel Alloy Pipes Seamless Solution for Demanding Environments

Hastelloy C-276 seamless pipe is a high-performance nickel-based alloy tubular product, engineered for aggressive industrial environments. As a seamless variant, it eliminates weld seams—avoiding common weak points like corrosion concentration or pressure-induced cracking—making it a reliable choice for critical applications requiring uncompromised durability.​
1. Core Material Properties​
  • Chemical Composition: Nickel (≥52%, base metal), Molybdenum (15–17%, anti-pitting/crevice corrosion), Chromium (14.5–16.5%, oxidation resistance), Tungsten (3–4.5%, strength enhancement), and low Carbon (≤0.02%, prevents carbide precipitation).​
  • Mechanical Performance: Tensile strength (≥895 MPa), yield strength (≥415 MPa), elongation (≥40%), and elastic modulus (~205 GPa). Maintains rigidity and ductility even at high temperatures (up to 1,093°C).​
2. Key Advantages​
  • Exceptional Corrosion Resistance: Withstands strong acids (sulfuric, hydrochloric), chloride-rich media (seawater, brines), and mixed chemicals. Annual corrosion rate in 20% boiling hydrochloric acid is ≤0.1 mm/year (far better than 316L stainless steel).​
  • Seamless Durability: Weld-free design ensures uniform pressure-bearing capacity and no leak risks from weld defects, suitable for high-pressure systems.​
  • High-Temp Stability: Resists creep and oxidation at elevated temperatures, maintaining performance in heat-intensive processes.​
3. Typical Applications​
  • Chemical Processing: Reaction vessels, heat exchangers, and pipelines handling acidic or reactive fluids.​
  • Environmental Engineering: Flue gas desulfurization (FGD) systems (resists sulfur-containing corrosives).​
  • Marine & Offshore: Seawater cooling pipelines and subsea equipment (withstands chloride corrosion).​
  • : Clean reactors and piping (high purity, resists sanitizing agents).​
4. Manufacturing & Quality Assurance​
  • Production Process: Hot piercing of alloy billets → hot rolling for dimensional refinement → annealing (to restore ductility) → surface pickling/passivation (enhances oxide layer protection).​
  • Testing: Ultrasonic testing (UT) for internal defects, eddy current testing (ECT) for surface flaws, and hydrostatic testing (1.5x rated pressure) for leak tightness.​
  • Standards Compliance: Meets ASTM B575 (alloy sheet/plate), ASTM B574 (alloy bars), and ASME Section VIII (pressure vessel requirements).​
5. Why Choose It?​
Ideal for harsh environments where material failure could cause downtime, safety risks, or product contamination. Its long service life (10–20 years) reduces maintenance costs, offering excellent long-term value.​
