5083/5086 aluminum plate for pressure vessels
Pressure vessels play a vital role in industrial production and are widely used in petrochemical, energy, pharmaceutical and other fields. Since their working environment usually involves harsh conditions such as high temperature, high pressure, and corrosive media, material selection and performance evaluation have become key links to ensure the safe and reliable operation of pressure vessels.
Aluminum used for pressure vessels includes 5083 aluminum plate, 5182 aluminum plate, 5754 aluminum plate, 5086 aluminum plate, etc. The five-series aluminum plate is an aluminum-magnesium alloy aluminum plate, which is the aluminum plate series with the best comprehensive performance among the current eight aluminum plate series. The main alloying elements of the 5-series aluminum plate are aluminum and magnesium, of which the magnesium content is between 3% and 6%. The different magnesium content determines the performance difference between different grades of the 5-series aluminum plate.
What requirements should the material of the pressure vessel meet?
1. Strength requirements
Pressure vessels need to withstand internal pressure and external loads, so the material must have sufficient strength. Strength indicators include yield strength, tensile strength, etc. For example, in high-pressure gas storage containers, high-strength steel is usually selected.
2. Toughness requirements
To prevent brittle fracture of the container during operation, the material should have good toughness. Toughness can be evaluated by impact tests and other methods. For example, pressure vessels working in low temperature environments should choose materials with good low-temperature toughness.
3. Corrosion resistance requirements
When the container is in contact with corrosive media, the material needs to have corresponding corrosion resistance. According to the properties of the medium, corrosion-resistant materials such as stainless steel and titanium alloy can be selected.
4. Machinability and weldability requirements
The material should be easy to process and weld to ensure the manufacturing quality and efficiency of the container. Some high-strength materials may have defects such as cracks during welding, and special welding processes are required.
