ភាសាខ្មែរFlanges are an important component of piping and valve systems in industrial applications. They are used to connect pipes and valves to form a complete system. Flange materials must ensure high performance and durability in the harsh environments of industrial applications.
6 common flange manufacturing materials on the market
Steel flange manufacturing materials
Steel flanges are flanges made from steel. A solid material that has good strength and heat resistance. Steel is an alloy of iron and carbon, with other alloys such as nickel, chromium, and manganese added to improve the material’s properties.
Steel flanges are widely used in harsh industrial applications, such as:
- In oil systems
- In gas systems
- Cooling systems
- Liquid systems.

Materials for manufacturing stainless steel flanges
Stainless steel flanges are flanges made from stainless steel, an alloy containing at least 10.5% Chromium.
- 304 stainless steel flanges have good corrosion resistance and are widely used in applications that do not require high-pressure resistance.
- 316 stainless steel flanges have higher corrosion resistance and are used in applications that require high pressure and temperature resistance.
Although stainless steel flanges are also very popular, the cost of stainless steel flanges is often higher than other materials.
Cast iron flange manufacturing materials
- In wastewater treatment systems
- Drainage systems
- Gas piping systems
Cast iron flanges are a cheap and easy-to-fabricate flange material. However, they are not suitable for use in applications requiring high pressure and temperature resistance.
Aluminum flange manufacturing materials
Aluminum flanges are flanges made from aluminum. A lightweight, high strength, corrosion resistant, and easily machined metal.
Aluminum is a popular metal that is widely used in industrial applications. Because it has many advantages such as light weight, ductility, easy machining, and high corrosion resistance.
Aluminum flanges are commonly used in applications that do not require high pressure and temperature resistance, such as:
- In cooling systems
- Air handling systems
- Water supply systems
However, the cost of aluminum flanges is often higher than that of cast iron and steel materials.
Different types of aluminum flanges are also classified according to size and pressure. Flange pressure is measured in PSI (pounds per square inch) or bar.
Brass flange processing material
Brass alloy is the main material used to make brass flanges. It is an alloy of iron and copper, usually with a higher percentage of copper than iron.
Brass alloys have good corrosion resistance and are easy to process. Therefore, brass flanges are widely used in applications requiring high corrosion resistance, such as:
- In wastewater treatment systems
- Cooling systems
- Air duct systems
However, the cost of brass flanges is often higher than that of cast iron and aluminum materials. Therefore, the choice of flange material will depend on the specific requirements of the application. Including pressure, temperature, and corrosion resistance.
Materials for manufacturing plastic flanges
Plastic flanges are flanges made from plastic. A polymer material with good chemical resistance, easy processing, and low cost.
Nhựa được sử dụng rộng rãi trong các ứng dụng công nghiệp do:
- Lightweight
- Easily machined
- Highly corrosion resistant
Plastic flanges are often used in applications that do not require high pressure and temperature resistance. Typically in wastewater treatment systems, drainage systems, and gas pipelines.
However, plastic flanges are not suitable for use in applications that require high mechanical impact resistance. Therefore, readers need to carefully consider the factors of pressure, temperature, and corrosion. Before making a choice.
The characteristics of flanges made from the above materials are also very different. You can see more common types of flanges today to understand better!
Why choose flange manufacturing materials?
This is explained very simply. Because each material will have its points and properties. Based on them, the construction worker will use them in each system accordingly. When choosing the wrong material to make the wrong flange, will lead to consequences such as:
- Leakage: An unsuitable flange will not withstand the pressure or temperature when the fluid passes through. Over time, it will corrode, deteriorate, and cause leakage in the system. This not only wastes fluid, pollutes the environment but also easily causes fire and explosion.
- Reduced system life: Inappropriate manufacturing materials cause the flange to corrode quickly, become damaged, and have to be replaced. This affects the operating life of the entire system. Increased costs:
- Using more expensive materials also increases the cost of raw materials. Conversely, using substandard materials causes damage, repair, and replacement costs. Therefore, we also choose the right flange manufacturing material to balance all costs.
