Subsea tubes in austenitic stainless steel, duplex and super-duplex stainless steels for a wide range of subsea applications. Main applications for Sandvik subsea tubes are:
- Flowline pipe / line pipe
- Riser tubes
- Manifold piping
- Christmas tree piping
- Hydraulic lines for drilling risers
Sandvik's range of subsea tubes includes steels of ASTM 316L type, Sandvik SAF 2205 duplex stainless steel and Sandvik SAF 2507 super-duplex stainless steel.
New material for subsea applications
In the near future, Sandvik's new hyper-duplex material, Sandvik SAF 3207 HD, will be available for subsea applications. Sandvik SAF 3207 HD offers a unique combination of high strength and corrosion resistance which is not available today in any material.
|An austenitic stainless steel with low strength and moderate corrosion resistance.|
|Sandvik SAF 2205
|22Cr duplex stainless steel offering a strength level of 65 ksi / 450 MPa, which is approximately twice that of ASTM 316L. It also has higher resistance to certain types of corrosion and cracking.|
|Sandvik SAF 2507
|25Cr super-duplex stainless steel with a higher strength (80 ksi / 550MPa) and improved corrosion resistance compared to 22Cr materials.|
