About aluminium pipe

The aluminium pipe is a kind of nonferrous metal tube, which refers to pure aluminum or aluminum alloy extruded into longitudinal hollow metal tube material along its longitudinal length. There are one or more closed through holes, the wall thickness and cross section are uniform, and the product is delivered in straight or round form. Widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home and other industries.


1.     Specifications of aluminium tube

The standard specifications of aluminium tubes are 6, 8, 10, 12, 14, 18, 32, 38, 45, 55, 75, 90, 110, 25, 115 and 120, respectively, and the units are mm.

The specification and specification of aluminum pipe comply with the “GB/T 4436-2012 aluminum and aluminum alloy pipe dimension and allowable deviation”. This standard specifies the size and allowable deviation of aluminum and aluminum alloy round tube, rectangular tube, square tube, regular hexagon tube, positive eight side tube and elliptical tube.

This standard is applicable to aluminum and Aluminum Alloy hot extrusion seam pipe, seamless pipe, welded tube, square tube, rectangular tube, hexagon is eight sided tube, cold rolling seam pipe, seamless pipe, cold drawn welded or seamless pipe, square pipe, rectangular tube, oval tube.

2.        Classification and application of aluminium tube

Aluminum has corrosion resistance and light weight, is widely used in industries such as: automobile, ships, aerospace, aviation, electronics, agriculture, electronics, Home Furnishing, aluminum has been everywhere in our life.

According to the shape of the aluminum pipe can be divided into: square tube, round tube, pattern tube, special-shaped pipe;

According to the extrusion method is divided into: seamless aluminum tube, ordinary extrusion tube;

According to the accuracy is divided into: ordinary aluminum tube, precision aluminum tube, in which the precision aluminum tube generally needs to be processed after extrusion, such as cold drawn, fine drawn, rolling;

According to the thickness is divided into: ordinary aluminum tube, thin walled aluminum tube.
