KCMSS: Delivering Excellence in SUPER DUPLEX PIPE UNS S32750/2507 To Singapore for Offshore & Marine Solutions
1. Introduction: SUPER DUPLEX PIPE UNS S32750/2507 in Offshore Engineering
SUPER DUPLEX PIPE UNS S32750 (also known as SUPER DUPLEX 2507 PIPE) is a critical material for offshore and marine applications due to its exceptional resistance to chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion13. Its dual-phase microstructure (austenite and ferrite) ensures high mechanical strength (≥800 MPa tensile strength) and durability in harsh environments such as seawater, subsea pipelines, and high-pressure hydraulic systems.
For Offshore & Marine Solution (Singapore) Pte Ltd, which specializes in subsea infrastructure, SUPER DUPLEX 2507 PIPE provides unmatched reliability for:
- Subsea umbilicals and control systems
- High-pressure risers and flowlines
- Seawater cooling and desalination systems.
2. Technical Specifications: ASTM A790 Seamless Super Duplex Pipe 2507
The ASTM A790 standard governs the production of seamless SUPER DUPLEX 2507 PIPES, ensuring compliance with rigorous mechanical and chemical requirements. Below are the dimensions supplied to the Singapore client:
| Parameter | Value |
|---|---|
| Outer Diameter (OD) | 377 mm |
| Wall Thickness | 12 mm / 14 mm |
| Length | 1000 mm (cut-to-length) |
Key Material Properties:
