If you’ve ever wondered how pipes, valves, and equipment are connected in various industries, you’ll find them in a crucial component known as “Body Flanges.” In this article, we’ll explore what body flanges are, the different types available, the materials used to make them, and where they are used.
What Are Body Flanges?
Imagine a scenario where you need to connect two pipes securely while ensuring they remain leak-free, even under high pressure and temperature conditions. That’s where body flanges come into play. Body flanges are like strong connectors that join pipes, valves, pumps, and other equipment together to create a network of pipes, allowing fluids to flow smoothly.

Types of Body Flanges
Body flanges come in various types, each designed for specific purposes, Some of them are mentioned below-
1. Weld Neck Flange
Weld Neck Flanges are the most commonly used type. They have a neck extension and a weld bevel, making them ideal for high-pressure applications.
2. Slip On Flange
Slip On Flanges are simpler alternatives to Weld Neck flanges. They accept the pipe into the center/bore and allow welding around the outer diameter of the pipe.
3. Blind Flange
Blind Flanges are designed to cap off a pipe or end a line. They have no bore or inner diameter and can be customized for specific needs.
4. Socket Weld / Counter Bore Flange
Socket Weld or Counter Bore Flanges have a socket for inserting the pipe when space is limited, making them useful in tight spaces.
5. Threaded / Companion Flange
Threaded or Companion Flanges have female NPT threaded centers for connecting to male threaded piping. They are commonly used in reducing connections.
6. Lap Joint Flange
Lap Joint Flanges are intended to fit over a stub end fitting. They have an extended hub and a machined radius at the base of the flat face.
Materials Used in Body Flanges
Body flanges are made from various materials, each chosen based on the application’s requirements:
Stainless Steel
Stainless steel body flanges are used in applications where corrosion resistance is crucial. Grades like 304, 316, and 317 are commonly used.
Duplex & Super Duplex Steel
These are used in demanding environments and are known for their high strength and corrosion resistance.
Alloy Steel
Alloy steel body flanges are suitable for high-temperature applications. Common alloys include F1, F5, F9, and F11.
Carbon Steel
Carbon steel body flanges are versatile and cost-effective. They are often used in industrial settings.
Nickel Alloys
Nickel alloy body flanges, like Inconel and Monel, are used in extreme conditions with high temperatures and pressures.
Copper Alloys
Copper alloy body flanges, such as Cu-Ni 90/10 and Cu-Ni 70/30, are used in specific applications, including seawater environments.
