Pipes & Tubes
Pipes and tubes are essential components in industrial systems used for conveying fluids, gases, and sometimes solids. While both serve similar functions, pipes are typically used for transporting fluids and are specified by their nominal diameter and schedule (wall thickness), whereas tubes are often used in structural and precision applications and are defined by their exact outside diameter and wall thickness. They are manufactured in seamless and welded forms using materials like carbon steel, stainless steel, alloy steel, copper, nickel alloys, and titanium, depending on the application. Pipes and tubes are widely used in industries such as oil & gas, chemical, power plants, automotive, construction, and aerospace. Standards for pipes include ASTM, ASME, API, and DIN, while tubes often follow ASTM, BS, and EN specifications.
