Seamless vs. Welded Stainless Steel 304 Pipe
When deciding which Stainless Steel 304 Pipe to choose for your system, consider the primary mechanical differences:
- Seamless Stainless Steel 304 Pipe: Manufactured from a solid billet without any weld seams. It offers uniform wall strength, superior pressure integrity, and high reliability under severe pressure, thermal shocks, and mechanical stress.
- Welded Stainless Steel 304 Pipe: Formed by roll-forming steel strip/plate and joining the longitudinal seam via ERW or EFW processes. It provides tight wall-thickness tolerances, high surface consistency, and excellent cost efficiency for low-to-medium pressure applications and larger diameters.
