Brass Flanges

Brass flanges are an essential component in many industrial and commercial applications. They can be used to seal pipes, valves, and other components to ensure a secure connection. Brass flanges provide superior strength and corrosion resistance compared to other materials such as plastic or aluminum. Additionally, brass flanges are available in different sizes and configurations for various types of applications.

The design of brass flanges makes them ideal for use in low-pressure systems where higher pressure ratings may not be required.

The material also provides excellent thermal conductivity for heat transfer applications, making it suitable for many process engineering projects. Furthermore, its wear resistance helps maintain the integrity of connections over time by preventing leaks from forming due to friction or vibration from machinery. Brass flanges also have excellent acoustic performance, which is ideal for sound insulation applications.

Brass flanges are available with various connection types such as threaded, socket welded, or slip-on. Each type of connection has a specific purpose and provides different levels of strength and reliability depending on the application requirements. Brass flanges can also be used in combination with other fittings such as gaskets, O-rings, and nuts to form a seal between two pipes or components. This ensures secure connections and prevents leaks from occurring.

Overall, brass flanges provide superior durability and dependability in many industrial applications. From low-pressure systems to high-temperature processes and thermal transfer operations, these versatile components offer reliable performance with minimal maintenance needs.

At Inox Pumps, we test these Brass Flanges under various quality checks to ensure they are defect-free and suitable for various industrial applications.
