Although the terms pipe and tube are often used interchangeably, in most cases, in terms of function, we generally default to PIPE for large tubes and TUBE for small tubes, pipes being used for transport, such as oil and gas control lines, and tubes being used for other applications such as heat exchange.
Seamless steel pipes/tubes manufacturing
Seamless pipe/tube is defined as - they do not have welded seams. Seamless pipes/tubes are manufactured through an extrusion process where the tube is extruded from solid round steel into a hollow shape and then formed into a qualified seamless tube through multiple processes such as piece, pickling, heat treatment, cold rolling or cold drawing, and inspection.
As we can see from the manufacturing process of seamless pipes/tubes, seamless pipes/tubes are completely homogeneous tubes with characteristics that make them stronger, more resistant to corrosion, and able to withstand higher pressures. This makes them more suitable for critical applications in harsh environments and, of course, relatively more expensive for seamless tubes.
MT produces seamless tubes in stainless steel:
Austenitic: 304/304L, 316/316L, 347/347H, 321/321H, 904L, etc.
Ferritic: 405, 409, 410, 430, 444, 446, etc.
Duplex steel: S31803, S32750, S32760, etc.
