Seamless Vs. Welded Stainless Steel Pipe

Worldwide Pipe & Supply supplies both seamless and welded 304/304L stainless steel pipe. Seamless 304 Stainless Steel pipe does not have a welding seam so it can sometimes be more expensive than welded stainless steel pipe, however, it outperforms welded pipe in high-pressure environments. Welded 304 stainless steel pipe is a steel tube that has a welded seam, and the type of tube is more affordable and versatile for a wide range of applications.
