Clad seamless aluminum pipe tube is better than slit aluminum pipe pressure, seamless pipe texture is more uniform, welded pipe in the weld part of the chemical composition will have a small amount of burning loss, so the mechanical performance is slightly poor but not greatly different.Seamless aluminum tube is recommended if it is used for bending.Welded pipes crack easily.If the bending radius is large, that's fine.Seamless aluminum tubes are formed by perforated extrusion, while conventional aluminum tubes are generally extruded by combined die.Short bar, high temperature, slow extrusion process is used in production, especially in the control of "three temperatures".



Clad seamless aluminum pipe tube and slit aluminum tube using the aluminum ingot processing method is different, seamless aluminum tube using surface turning, slit aluminum tube using no oxide skin involved.
In terms of mechanical properties, Clad seamless aluminum pipe tube products have uniform metal flow, high dimensional accuracy, good fatigue resistance, consistent mechanical properties and no layered structure.The head and tail metal flow of aluminum tube with seam is not uniform, the mechanical properties are not consistent, and the layered structure is easy to appear.In general, it is better to choose seamless aluminum tube, but also need to determine the choice according to their own conditions.
