GB Aluminum Round Pipe

Aluminum pipe is a kind of non-ferrous metal pipe, refers to the use of pure aluminum or aluminum alloy by extrusion into its longitudinal full length of hollow metallic tubular materials.

Aluminum tubes are mainly divided into the following

According to the shape: square Tube, round pipe, pattern tube, special-shaped pipe, universal aluminum tube.

By extrusion: seamless aluminum tubes and ordinary extrusion tubes

Extrusion Aluminum pipe: billet heating → hot extrusion → sawing → wagon, boring → wool heating → two times extrusion → tension straightening or roller straightening → cutting chuck → intermediate inspection → annealing → corrosion → scraping repair → cold rolling → annealing → The head → the Tensile → quenching → the whole diameter → The finishing straightening → The product sampling → The precision → the injection, the inspection, the acceptance → oiled, Packaging.

Seamless aluminum pipe: Seamless aluminum pipe is the use of perforated extrusion method, and conventional aluminum pipe is generally used combined mode extrusion. The production of short rod, high temperature, slow extrusion process, especially to control the "three temperature", aluminum rods, extrusion cylinders, and molds to maintain a clean, aging time and temperature according to the thickness of the pipe wall of the size of a pipe diameter to make appropriate adjustments on it. Large seamless aluminum pipe, is generally hot extrusion forming, and then after the effective treatment of the following; Small seamless aluminum tube, can be hot extrusion can also be cold stretching, and then after the actual treatment.

According to the precision points: ordinary aluminum pipe and precision aluminum pipe, wherein precision aluminum pipe generally need to be re-processed after extrusion, such as cold pull fine pumping, rolling.

by thickness: ordinary aluminum tubes and thin-walled aluminum tubes
