Aluminum Flanges

Aluminum Flanges  are also called flange plates or flange plates. Flanges are parts that connect pipes and pipes to each other and are connected to the end of the pipe; Aluminum Flanges are also used at the inlet and outlet of the equipment to connect between two equipment, such as reducer flanges. Flange connection or flange joint refers to a detachable connection consisting of flanges, gaskets and bolts connected to each other as a set of combined sealing structure. Pipeline flanges refer to flanges used for piping in pipeline installations and are used in equipment The above refers to the inlet and outlet flanges of the equipment. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets.

The advantages of High Quality Aluminum Flanges Supplier over other flange products are as follows:

1. Lightweight: Aluminum flanges are lighter than other material flanges. It can save transportation and processing costs.
2. Good strength: The mechanical properties of aluminum flanges are not as good as steel, but higher than its strength. Alloy elements such as copper, magnesium, and manganese can be added to make aluminum alloys and then heat treated to obtain high strength.
3. Beautiful and suitable for various surface treatments: the aluminum flange and its alloy flange have an oxide film on the surface, which is silver-white and relatively beautiful. If it is oxidized, the oxide film on the surface will be firmer, and it can also be painted with dyeing. Create a variety of colors and glossy surfaces.
4. Corrosion resistance and good scene resistance: aluminum and aluminum alloy flanges can form hard and dense oxide films on the surface of the country, and many substances will not cause degradation to it.
5. Chemical resistance: The aluminum flange does not react to chemicals such as nitric acid, glacial acetic acid, hydrogen peroxide, etc., and has very good resistance to chemicals.
6. No magnetism: The aluminum flange is a non-magnetic body.
7. Non-toxic: Aluminum itself is not toxic, so aluminum flanges are more suitable for medical machinery and food processing industries.
8. Low temperature resistance: When the temperature is low, the strength of aluminum flange increases without brittleness, so it is a ideal material for cryogenic devices.

Aluminum Plate Flanges production process

The production process is mainly divided into four types: forging, casting, cutting and rolling.

Cast flange and forged flange

The cast aluminium flange has accurate shape and size, small processing volume and low cost, but has casting defects (pores, cracks, inclusions); the internal structure of the casting is poor in streamline (if it is a cutting part, the streamline is worse);

Forged aluminium flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings are streamlined, have a denser structure, and have better mechanical properties than cast flanges;

Improper forging process will also cause large or uneven crystal grains, hardening cracks, and forging costs higher than cast flanges.

Forgings can withstand higher shear and tensile forces than castings.

The advantage of castings is that they can produce more complex shapes and lower costs;

The advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the casting;

From the production process, the difference between cast flange and forged flange is different. For example, centrifugal flange is a kind of cast flange.

Centrifugal flanges belong to the precision casting method to produce flanges. Compared with ordinary sand casting, the structure of this type of casting is much finer and the quality is improved a lot. It is not prone to problems such as loose structure, pores, and trachoma.
