Stainless steel pipes are high-strength, corrosion-resistant alloys of iron, chromium, and carbon, used for transporting liquids and gases in industries like oil, mining, and food processing. Available in seamless or welded forms (grades 304/316), they feature sizes ranging from small diameter up 1/8”-30” NB (Nominal Bore) and various schedules (SCH10, SCH40, SCH80) for pressure applications.
