Precision aluminum tube is a kind of high-precision aluminum tube material processed by cold drawing or hot rolling. Knowing the product variety is more conducive to your choice, the variety of aluminum pipes is completely comparable to the diversity of biological species in small areas. Now let me introduce to you.
  First, the classification of precision aluminum tubes: precision aluminum tubes are divided into two categories: precision aluminum tubes and welded precision aluminum tubes (seamed tubes). According to the cross-sectional shape, it can be divided into round tube and special-shaped tube. The widely used is the round precision aluminum tube, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped precision aluminum tubes. For precision aluminum tubes that are under fluid pressure, hydraulic tests must be carried out to check their pressure resistance and quality. It is qualified if no leakage, wetting or expansion occurs under the specified pressure. Carry out curling test, flaring test, flattening test, etc.
  Second, precision aluminum tubes: precision aluminum tubes are made of aluminum ingots or solid tube blanks through perforation to make capillaries, and then hot-rolled, cold-rolled or cold-drawn. The specification of precision aluminum tube is expressed by outer diameter * wall thickness mm. Precision tubes are divided into two categories: hot-rolled and cold-rolled (dial) precision tubes. Hot-rolled precision tubes are divided into general precision tubes, low and medium pressure boiler precision tubes, high pressure boiler precision tubes, alloy precision tubes, stainless precision tubes, petroleum cracking tubes, geological precision tubes and other precision tubes. In addition to general precision tubes, low and medium pressure boiler precision tubes, high pressure boiler precision tubes, alloy precision tubes, stainless precision tubes, petroleum cracking tubes, and other precision tubes, cold-rolled (dial) precision tubes also include carbon thin-walled precision tubes. Tube, alloy thin-walled precision tube, stainless thin-walled precision tube, special-shaped precision tube. The outer diameter of hot-rolled seamless tubes is generally greater than 32mm, and the wall thickness is 2.5-75mm. The diameter of cold-rolled precision tubes can reach 6mm and the wall thickness can reach 0.25mm. Higher dimensional accuracy than hot rolling.
  Third, the general use of precision tubes to ensure the strength and flattening test. Hot-rolled precision tubes are delivered in a hot-rolled state or heat-treated state; cold-rolled precision tubes are delivered in a heat-treated state.
  Due to the advantages of no oxide layer on the inner and outer walls of the precision seamless aluminum tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as Cylinders or cylinders can be seamless pipes or welded pipes. Precision tubes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless aluminum tubes for medium and low pressure boilers, etc., and can also be used in bearings, hydraulics, machining and other fields!
