Frequently Asked Questions (FAQ)
1. What is the difference between 2205 and 2507 duplex pipe?
2507 offers higher chromium, molybdenum, and nitrogen content, resulting in superior pitting resistance and higher strength compared to 2205.
2. Is 2507 pipe suitable for seawater applications?
Yes. 2507 super duplex is specifically designed for harsh chloride environments and performs exceptionally well in seawater systems.
3. Do you supply both seamless and welded pipes?
Yes, we provide both seamless and welded 2507 stainless steel pipes in various dimensions.
4. Can you provide third-party inspection?
Yes, third-party inspections such as SGS, BV, or TUV can be arranged upon request.
