Stainless Steel Pipe
Stainless Steel has inherrent characteristics that lend themselves to the design of thin wall piping systems:
- Resistant to corrosion
- Reduced oxidation
- Resists high temperatures
- Low maintenance costs
- Very low risk of contamination
Pipe is produced in a specific range of sizes (see table below) and is available in grades 304 and 316, in approximately 6m lengths for welded pipe, and between 5m and 7m length for seamless.
