304 Stainless Steel Welded Pipes
A 304 stainless steel welded pipe is a corrosion-resistant process pipe produced by forming stainless steel strip and welding it longitudinally.
It is used on water, compressed air, food and general industrial lines. The product range includes 9 diameters in AISI 304L from Ø21.3 mm to Ø114.3 mm, with 2 mm wall thickness and 6 m length.
Main Applications
- Water and process water lines
- Compressed air systems
- Food and beverage plants
- Heating and cooling lines
- Architectural and handrail work
- General industrial piping
