The different of the seamless aluminum tubing and welded aluminum tubing Posted on March 8, 2016 by detect-metals Seamless aluminum tubes than the pressure better welded aluminum tubes, seamless aluminum tubing texture more uniform weld pipe in some chemical components of a small amount of burning, so the mechanical properties slightly inferior, but not a big difference. If the elbow is recommended to use the words of seamless pipe. Welded easy to crack. Relatively large bending radius, then no problem. In the case of the same material of aluminum: 1, seamless aluminum tubing can be done with items such as fluids: Important stamping parts water, air and other hydraulic, machining parts, grinding, etc. apply. 2, aluminum pipe joints are generally made with structural support, as some do not need high-precision parts used in general supporting role more, but on the fluid used.
