Aluminum alloy pipeline, aluminum alloy compressed air pipeline system has been widely used in European and American enterprises to transport compressed air, vacuum, nitrogen and inert gas.

Aluminum alloy pipes, extruded alloy aluminum pipes and profiles adopt the production process of ingot heating extrusion finishing; For aluminum alloy materials that can be strengthened by heat treatment, quenching aging treatment is also required.

The production process of on-line air-cooled quenching and finishing after extrusion is adopted for building profiles. Aluminum alloy pipe thin-walled pipe adopts the production process of first extruding and then cold processing. For hard alloy small-diameter pipe, the production process of twice extruding and then cold processing is often used to produce small-sized extruded pipe blank. When there is no pressure on the pressure gauge with limit pin, the pointer cannot return to the limit pin after rotating; When there is no pressure on the pressure gauge without limit pin, the value of the pointer from the zero position exceeds the allowable large error specified by the pressure gauge.

Generally, aluminum and aluminum alloy are divided into deformed aluminum alloy and cast aluminum alloy. Deformed aluminum alloy can be divided into non heat treatment strengthened aluminum alloy and heat treatment strengthened aluminum alloy. Our common aluminum alloy plates, aluminum alloy bars and aluminum alloy pipes sold in the market are all deformed aluminum alloys. Wrought aluminum alloy refers to the aluminum alloy material produced by forging, rolling, extrusion and other forming processes after casting into ingots by ingot metallurgy.
