Product Description

Hastelloy B-3 Seamless Pipes: Advanced Corrosion-Resistant Piping Solutions

Hastelloy B-3 seamless pipes represent the pinnacle of corrosion-resistant piping systems, designed for critical applications where weld defects and material inconsistencies are intolerable. This alloy's enhanced thermal stability and resistance to stress corrosion cracking (SCC) make it ideal for modern chemical processes involving high pressure, elevated temperatures, and complex acid mixtures.

Microstructural Superiority

• Stable FCC Structure: The alloy's face-centered cubic (FCC) structure, stabilized by 65% nickel, prevents secondary phase formation during thermal cycling.
• Self-Repairing Passive Layer: Controlled molybdenum distribution (28.5% Mo) creates a protective layer that resists:
  • Pitting and crevice corrosion
  • Knife-line attack in weld zones
  • SCC in HS environments

Operational Benefits

• Extended Service Life: 5-7 times longer than 316L stainless steel in HCl service.
• Flow Optimization: Smooth hydraulic performance reduces pumping energy by 15-20%.
• Wide Temperature Range: Continuous operation from -196°C to 400°C.
• Purity Preservation: Non-reactive surface prevents cross-contamination and maintains media
