How to Select the Right Nickel Alloy Pipe for Your Project?
Choosing the correct alloy depends on several factors, including:
- Operating Temperature: Is it ambient, high, or cryogenic temperature?
- Corrosive Medium: Specifically which acid, alkali, or salt? What are the concentration and impurity levels (e.g., chlorides)?
- Pressure Conditions: Is the system high pressure, low pressure, or vacuum?
- Budget & Service Life Requirements: How to balance initial cost with long-term maintenance costs?

Frequently Asked Questions (FAQ)
Q: Which is more resistant to hydrochloric acid corrosion, Inconel 625 or Hastelloy C276?
A: At room temperature and low concentrations, Hastelloy C276 generally performs better. However, in environments containing oxidizing agents or at high temperatures, Inconel 625 might be more suitable. The specific choice requires analysis based on actual operating conditions.
Q: Can you provide materials compliant with the NACE MR0175 standard?
A: Yes. Products from many of our grades (such as Inconel 625, Hastelloy C276) can meet the NACE MR0175/ISO 15156 standard, making them suitable for sour oil and gas field environments.
Q: What is the minimum order quantity, and what is the delivery time?
A: We offer flexible order services. Specifics depend on product specifications and stock availability. Please contact our sales team for accurate information.
