Overlap Aluminum Plastic Pipe:
As the name implies, lap joint refers to lap the two ends of the aluminum layer in the middle of the tube together to form a tube shape. Due to the overlapping part of the aluminum pipe of the lap joint aluminum-plastic composite pipe, its cross section is not a complete circle, which will inevitably affect the shape and wall thickness uniformity of the pipe. Also, because the ultrasonic welding machine can only weld thin-walled aluminum tubes, its thickness is usually in the range of 0.2 to 0.6 mm; the strength and stiffness of the aluminum-plastic composite tube with this thickness of the aluminum layer are relatively low, but the tube material is moderately soft and hard, which is convenient for bending correction. straight.
Laser Aluminum Plastic Pipe:
Butt welding refers to cutting off the excess part of the aluminum strip and welding the ends together to form a seamless tube. The cross-section of the aluminum-plastic pipe of the butt-welded aluminum-plastic pipe is a complete circle. Its welding strength is much higher than that of ultrasonic welding of lap welding, and the thickness of the welded aluminum tube ranges from 0.3 to 2 mm, or even thicker.
