316 Stainless Steel Seamless Pipes
A 316 stainless steel seamless pipe is produced by piercing and drawing molybdenum-alloyed 316L billet, giving a seamless pipe resistant to chloride media.
It is used on high-pressure chemical process, seawater, hydraulic and instrument lines. Diameter, wall series and length are confirmed against stock and production schedules.
Main Applications
- High-pressure chemical lines
- Seawater and offshore piping
- Hydraulic and instrument lines
- Pharmaceutical and food processes
- Heat exchanger and condenser tubes
- Bent lines in aggressive media
