Drawn Seamless Pipe Advantages vs. Extruded Tube
1. Dimensional Tolerances-Because the tube is drawn over a mandrel and through a die, consistent dimensions can be achieved.
2. Superior Strength-Cold work increases tube strength and is stronger that an equivalent extruded tube.
3. Attractive Appearance-The drawing process enhances tube cosmetics by producing a bright finish with no weld lines.
4. Machining-The drawn tube’s superior strength and hardness characteristics enhance tube machinability. This assures a better machined surface with less gumming.
5. Bending-Better dimensional and temper characteristics greatly enhance tube bending operations. Consistent dimensions and temper reduce bender setup time and require less machine adjustments. Tube spring back is enhanced. Precise bends can be obtained.
6. Anodizing-The draw process refines the surface of the tube eliminating extrusion die lines and other surface irregularities. This provides a superior finish for bright dip and etches and clears anodizing.
