Why Super Duplex Steel UNS S32750 Pipe?

1. Unmatched Corrosion Resistance

Super Duplex Steel UNS S32750 Pipe excels in aggressive environments, offering PREN ≥40 to resist pitting, crevice corrosion, and chloride stress corrosion cracking (SCC). Ideal for seawater desalination systems or sour gas pipelines.

2. Dual Manufacturing Options

Choose between seamless pipes for high-pressure subsea applications or welded pipes for cost-sensitive projects—both deliver consistent performance under temperatures from -50°C to 250°C.

3. Global Compliance & Traceability

Our pipes comply with NACE MR0175, PED, and DNV-GL standards, backed by full material traceability (EN 10204 3.2 certs) and hydrostatic testing reports.

4. Ready-to-Ship Inventory

With pre-stocked sizes (½"–24" OD, SCH 10S–160) and regional hubs in Houston, Rotterdam, and Singapore, we guarantee 15-day delivery—even for urgent orders.

Applications Built for Durability

Offshore Oil & Gas: Risers, process piping, and hydraulic lines exposed to seawater.
Chemical Processing: Heat exchangers and reactors handling acids/alkalis.
Subsea Systems: Umbilicals and manifolds requiring high mechanical strength.

How We Ensure Quality?

Advanced Testing: Ultrasonic (UT) and radiographic (RT) inspection, PMI verification.
