Aluminum alloy spiral welded pipe

Features of aluminum alloy spiral welded pipes:

1. High strength: The circumferential stress of aluminum alloy spiral welded pipes forms a certain angle, and the strength is higher than that of straight welded pipes due to smaller stress;

2. Good Forming: The aluminum alloy spiral welded pipe is well formed, with a difference in roundness of less than 0.1% of the inner diameter of the welded pipe. The allowable deviation of the outer diameter of the pipe end is ± 2 mm, and the straightness is ± 2mm. It can be cut into typical lengths of 12m-18m, effectively improving the quality of pipeline construction and significantly improving construction efficiency;

3. High production efficiency: Aluminum alloy spiral welded pipes are widely used because they can produce shells with different diameters and higher strength using narrower plate and strip materials. Has advantages such as antioxidant and low temperature resistance.
