FAQ
Q1: How does Hastelloy C-276 differ from Inconel 625 in HCl service?
A: C-276 offers 50% lower corrosion rate in 20% HCl at 50°C, while Inconel 625 excels in higher-temperature oxidation resistance.
Q2: What welding methods ensure leak-proof joints?
A: Use orbital TIG (GTAW) with ERNiCrMo-4 filler, argon back purging, and post-weld anneal at 1,120°C (2,048°F) for C-276.
Q3: Are pipes certified for offshore sour gas pipelines?
Full compliance includes:
- NACE MR0175/ISO 15156
