BI-METALLIC (BLANKING) BRAZING FLANGES

Understanding the Different Types of Bimetal Flanges

---

Bimetal flanges come in various types, each with its unique features and specifications. Understanding the different types of flanges available is the first step in choosing the right flange for your project. The most common types of Bimetal flanges include Weld Neck, Slip-On, Blind, Socket Weld, Lap Joint, and Threaded flanges.

Weld Neck flanges are designed to provide a long-lasting and leak-free connection. They're commonly used in high-pressure piping systems and have a neck that's welded to the pipe, creating a smooth transition between the pipe and flange.

Slip-On flanges are easy to install and remove and are ideal for low-pressure systems. They're slipped over the pipe and then welded in place.

Blind flanges are used to close the end of a pipe or vessel and are commonly used in systems that require periodic inspection or cleaning.

Socket Weld flanges are similar to slip-on flanges but have a socket in the bore to allow the pipe to be inserted. They're commonly used in small-bore piping systems and have a high-pressure rating.

Lap Joint flanges are designed to be used with a stub end and are ideal for systems that require frequent dismantling. They're commonly used in low-pressure systems.

Threaded flanges have internal threads and are screwed onto the pipe. They're commonly used in low-pressure systems and are easy to install and remove.

Factors to Consider When Choosing Bimetal Flanges

Choosing the right Bimetal flange for your project requires careful consideration of various factors. Here are some of the critical factors to consider when selecting the right flange for your project.

Pressure Rating and Temperature Requirements The pressure rating and temperature requirements are essential factors to consider when choosing Bimetal flanges. The pressure rating is the maximum pressure that the flange can handle, while the temperature requirement is the maximum temperature that the flange can withstand. It's crucial to select a flange that can handle the pressure and temperature requirements of your project. Failure to do so can result in leaks, damage to equipment, and even safety hazards.

Size and Dimensions The size and dimensions of the flange must be compatible with the piping system. The size of the flange is determined by the size of the pipe to which it's connected. It's essential to select a flange that matches the size of the pipe to ensure a secure and leak-free connection. The dimensions of the flange, such as the bolt hole diameter, thickness, and outside diameter, must also be considered. The dimensions must match the piping system and other components to ensure a proper fit.

Corrosion Resistance and Material Selection Bimetal flanges are known for their excellent corrosion resistance, making them ideal for use in harsh environments. However, not all Bimetal alloys offer the same level of corrosion resistance. The material selection is critical when choosing Bimetal flanges. Factors such as the type of fluid or gas being transported, the temperature, and the level of corrosiveness must be considered. Some of the most commonly used Bimetal alloys for flanges include 304, 316, 321, and 347. It's essential to select the right material for your project to ensure corrosion resistance and longevity.

Flange Face and Surface Finish The flange face and surface finish are crucial factors that affect the sealing performance of the flange. The flange face can be flat, raised, or ring joint, and the surface finish can be smooth, serrated, or grooved. The flange face and surface finish must be compatible with the gasket and the mating flange to ensure a secure and leak-free connection.

End Connections and Joining Methods The end connections and joining methods must be considered when choosing Bimetal flanges. The end connection can be butt-weld, socket-weld, threaded, or flanged. The joining method must be compatible with the piping system and other components. Factors such as the pressure and temperature requirements, the level of vibration and movement, and the ease of maintenance must be considered when selecting the right joining method.

Applications and Uses of Bimetal Flanges

Bimetal flanges are used in a wide range of industrial applications, including:

Chemical Processing Bimetal flanges are ideal for use in chemical processing applications, where they can provide superior resistance to corrosion and wear. They are commonly used in the production of chemicals such as acids, alkalis, and solvents, as well as in the handling and storage of hazardous materials.

Oil and Gas Production Bimetal flanges are also commonly used in the oil and gas industry, where they can provide excellent resistance to corrosion, wear, and high temperatures. They are used in a variety of applications, including drilling, production, transportation, and storage.

Power Generation Bimetal flanges are used in power generation applications, where they can provide excellent resistance to high temperatures and pressures. They are commonly used in the production of steam, as well as in the handling and storage of fuels and other materials.
