Super Duplex Pipe is a high-performance austenitic-ferritic stainless steel pipe, most commonly grade 2507 (UNS S32750) or Zeron 100 (UNS S32760), manufactured to ASTM A790 / A928 with dimensions per ASME B36.19M. Its PREN rating of 40+ gives it roughly double the yield strength of 316L along with far superior resistance to chloride pitting and stress corrosion cracking – which is why EPCs specify Super Duplex Pipe for offshore platforms, desalination intakes, sour gas lines and subsea injection systems where a wall-thickness failure isn't an option. We keep Super Duplex Pipe PMI-verified and ex-stock across every schedule from SCH 10S to SCH XXS, ready to dispatch within 48 hours.

The question every EPC buyer asks: do I really need Super Duplex, or will standard 2205 hold up for less?
For seawater injection and sour service, Super Duplex earns back its premium in avoided failures. We’ve earned our name among the top Super Duplex Pipe Suppliers, known for genuine stock and dependable PMI reports.
Import buyers should also budget for Basic Customs Duty, which varies by origin country and grade – confirm current rates before shipment.

As a genuine Super Duplex Pipe Exporter, our footprint now stretches from Casablanca to Buenos Aires, with 2507 and Zeron 100 grade pipe ready on demand worldwide.
2507 has more molybdenum, chromium and nickel, giving it a PREN above 40 versus 2205’s mid-30s. This makes 2507 better suited to seawater and sour gas service.
ASTM A790 covers seamless and welded pipe, and ASTM A928 applies when filler metal is used. Dimensions follow ASME B36.19M.
2507 is UNS S32750 and Zeron 100 is UNS S32760. Both are super duplex grades with PREN above 40.
Yes. Its higher yield strength allows a thinner wall for the same pressure rating, reducing weight.
Every order ships with an EN 10204 3.1 mill test certificate. 3.2 certification, NACE MR0175 and PMI reports are available on request.
Ex-stock sizes dispatch within 48 hours. Large or indent orders usually take 6–10 weeks.
Yes, mildly, due to its ferritic-austenitic structure. It is more magnetic than fully austenitic grades like 316L.
