We manufacture and supply high quality aluminum flanges including: aluminum round pipe flange,ova aluminum flanges, flat face aluminum flange, raised face aluminum flange. Our company has domestic first-class cold production, hot extrusion, forging, welding, heat treatment and other advanced production equipment. Equipped with imported direct-reading spectrometers, metallography, mechanical properties, non-destructive testing and other advanced testing equipment, the raw material - production process - the entire process of product inspection, and effectively ensure the product quality.Our  products are widely used in petroleum, chemical, power, water, machinery, tankers, ships, natural gas and other fields.
Our company pays attention to product quality, has obtained ISO9001 quality management system certificate, pressure pipe special equipment manufacturing license, pressure vessel special equipment manufacturing license, classification society factory approval certificate, HSE health and safety environment management system certification and so on.

The advantages of aluminum round flange over other flange materials are as follows:
1. Light weight: aluminium flanges is lighter than other material flanges. You can save on handling and processing costs.
2. Good strength: aluminium flanges mechanical properties than steel, but higher than its strength, you can add copper, , manganese, magnesium and other alloying elements, made of aluminum alloy and then heat treatment, resulting in high strength.
3. Beautiful appearance, it is suitable for a variety of surface treatment: aluminium flanges and its alloy flange surface oxide film, silvery white, relatively beautiful. If oxidized, the oxide film on the surface is stronger, and it can also be dyed and brushed. Create a variety of colors and glossy surfaces.
4. Good corrosion resistance: aluminum and aluminum alloy flanges, the country's surface energy to produce a hard and dense oxide film, many substances do not have an erosion effect on it.
5. Chemical resistance: Aluminium flanges do not react to chemicals such as nitric acid, glacial acetic acid, and hydrogen peroxide, and have very good resistance to chemicals.
6. No magnetism: Aluminum flanges are non-magnetic.
7. Non-toxic: Aluminum itself is not toxic, so aluminium flange is more suitable for medical machinery and food processing industries.
8. Low temperature resistance: When the temperature of the aluminium flanges are low, the strength is increased without brittleness, so it is an ideal material for low temperature devices.
