Chemical composition and Mechanical properties of Chalco SCH40/SCH80 aluminum tube pipe
Chalco hot selling SCH40/SCH80 aluminum tube pipe products include 6061, 6063, 5083, 5086, 3003, 7075, seamless, welded, or welded drawing aluminum tube pipes.
Seamless pipes have no seams or solder joints, which enables them to better withstand high pressure and be more corrosion resistance.
Welded pipes are made by rolling and welding metal plates, which have weaker strength than seamless pipes and are not as round as seamless pipes, but they have more consistent wall thickness and can achieve stricter wall tolerances.
Welded drawing pipes are usually made by molds and mandrels to form smooth inner diameter welded pipes, which provide corrosion resistance comparable to seamless pipes while still providing stricter wall tolerances for welded pipes.
