304/304L Stainless Steel Pipe is ideal for all structural applications where greater strength and superior corrosion resistance is required. Having a durable mill finish and an interior welded seam, Stainless Pipe is widely used for all types of fabrication projects that are exposed to the elements - chemical, acidic, fresh water, and salt water environments.
Pipe is manufactured in either welded and or seamless form. Welded pipe is made by taking a flat plate (or skelp) which then is rolled into a tubular shape and further welded to finalize the form. Seamless is taking a solid bar (ingot), piercing a hole through its length and then drawing through dies to form the final size.
