Frequently Asked Questions – Super Duplex 2507 Flanges

1. What is Super Duplex 2507 Flange?

Super Duplex 2507 flange is a high-strength stainless steel flange made from UNS S32750 grade with excellent resistance to pitting, crevice corrosion and stress corrosion cracking.

2. What is the difference between S32750 and S32760?

UNS S32750 (ASTM A182 F53) contains 25% chromium, while UNS S32760 (ASTM A182 F55) includes added tungsten and copper for enhanced corrosion resistance in aggressive environments.

3. What industries use Super Duplex 2507 flanges?

These flanges are widely used in oil & gas, offshore platforms, desalination plants, chemical processing, marine engineering and power generation industries.

4. What pressure ratings are available?

Super Duplex 2507 flanges are available in Class 150, 300, 600, 900, 1500 and 2500 pressure ratings with RF, FF and RTJ facings.

5. Do you export Super Duplex 2507 flanges to Saudi Arabia and UAE?

Yes, we export Super Duplex 2507 flanges to Dammam, Riyadh, UAE, Qatar, Kuwait, Oman, Bahrain, Canada, Indonesia, Mexico and other global locations.

6. What standards do Super Duplex flanges follow?

Our flanges comply with ASTM A182 F53/F55, ASME B16.5, ASME B16.47, NACE MR0175 and ISO standards.

7. Are test certificates provided?

Yes, we provide Mill Test Certificates (MTC), PMI reports, NDT test reports and third-party inspection certificates upon request.

8. Why choose Super Duplex over Duplex stainless steel?

Super Duplex offers higher chromium, molybdenum and nitrogen content, providing superior corrosion resistance and nearly double the strength of standard austenitic stainless steel.
