SS 304L Seamless Pipe vs. Welded Pipe
Choosing the right manufacturing process depends on your system's operating pressure, structural needs, and budget:
- SS 304L Seamless Pipe: Manufactured without any weld seam from a solid round steel billet. It provides uniform structural integrity, higher working pressure limits, and superior performance in severe corrosive environments.
- SS 304L Welded / ERW Pipe: Formed longitudinally from steel strip or coil. It offers tight wall-thickness tolerances, cost efficiency in larger diameters, and smooth surface finishes suitable for general fluid transport.
