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).
Pharmaceuticals: 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.
