Product Description

Hastelloy B-3 seamless pipes embody the next evolutionary step in corrosion-resistant piping systems, specifically designed for critical applications where weld defects and material inconsistencies are unacceptable. The alloy's enhanced thermal stability and stress corrosion cracking (SCC) resistance make it ideal for modern chemical processes combining high pressure, elevated temperatures, and complex acid mixtures.

Microstructural Superiority

The alloy's face-centered cubic (FCC) crystal structure, stabilized by 65% nickel content, prevents harmful secondary phase formation during thermal cycling. Controlled molybdenum distribution (28.5% Mo) creates a self-repairing passive layer that actively resists:

• Pitting corrosion in chloride-rich brines

• Crevice corrosion under stagnant acid conditions

• Knife-line attack in weld-affected zones

• Stress corrosion cracking (SCC) in H2S-containing environments

perational Benefits

• Lifetime Cost Reduction: 5-7x longer service life than 316L stainless in HCl service

• Flow Optimization: Hydraulic smoothness reduces pumping energy by 15-20%

• Temperature Resilience: Continuous operation from -196°C to 400°C

• Cross-Contamination Prevention: Non-reactive surface preserves media purity
