Depending on your application, you may consider whether you need tubing or piping to convey your material - but you may find one superior to the other. Tube bending improves fluid-flow characteristics by creating compact systems with smooth directional changes. The 45 or 90-degree elbows used in piping systems frequently increase turbulence. Tubing systems produce better flow characteristics due to the smooth internal surface and reduce flow loss and drag. Tubing systems also support high pressures and typically a higher strength to weight ratio than piping.
