Many people know that aluminum tube, but aluminum tube is also divided into seam and seamless, seam aluminum tube and seamless aluminum tube has the following differences:

1. Aluminum ingot processing method indirect extrusion (seamless tube) surface turning, no oxide skin involved in direct extrusion (seam tube) skin not turning, the product may have oxide layer involved in aluminum ingot and filled ingot bucket action status seamless tube - body flow, no friction; Metal flow is uniform; There is relative friction in the welded pipe; Uneven metal flow; The product contains coarse crystals. Product appearance seamless tube inner and outer walls are smooth and clean; No burning or cracking on the surface; Welded pipe appearance finish general product mechanical properties seamless pipe product end metal flow uniform; High dimensional accuracy; Good fatigue resistance; Consistent mechanical properties; No lamellar structure. The metal flow from end to end of welded pipe products cannot be uniform; Inconsistent mechanical properties; Prone to layered tissue. Seamless tube is especially suitable for extruding all kinds of super-hard alloy bars, pipe profiles (such as 2014, 5056, 7075 series); Welded pipe is suitable for extrusion of alloy products of general hardness added value general economic seamless pipe price is relatively high, suitable for manufacturing high-precision products the price of welded pipe is relatively cheap, suitable for general product system.

2. Seamless aluminum tube can be used as fluid parts, such as water stamping, air hydraulic, machining parts, grinding and other important parts.

3. Welded aluminum tubes are generally used for structural supports. Like some parts that do not need high precision, the general aluminum tubes with support function are more often, but the pressure on the fluid is limited. The performance of seamless aluminum tube is stronger than that of stitched aluminum tube, and the weight it bears is higher than that of stitched aluminum tube. Seamless aluminum tube and welded aluminum tube each have advantages and disadvantages, you can according to their own needs, each needs, suitable is the right product!
