Carbon Steel Flanges – Types and Functions

types of carbon steel flanges

Are you looking for the best flanges to secure and connect pipes? Carbon steel flanges are among the most enduring and reliable pipe connectors. With their superior strength, durability, and impressive design features, carbon steel flanges can provide unparalleled functionality for various applications. In this blog post, we’ll discuss all you need to know about carbon steel flanges to choose the perfect solution for your pipe requirements.

What are Carbon Steel Flanges?

Carbon Steel Flanges function as connectors for pipes, seamlessly joining two sections together. Fashioned from durable carbon steel, they ensure a secure connection. Their robust build enables them to withstand higher pressures compared to alternative flanges. Moreover, these metallic connectors boast superior corrosion resistance, rendering them well-suited for industrial use.

Types of Carbon Steel Flanges

Slip-On Flanges

Slip-on flanges are the most common type of carbon steel flange. They are used to connect pipes to each other or to other components in a piping system. Slip-on flanges are easy to install and can be welded or threaded onto a pipe.

Weld Neck Flanges

Weld neck flanges are another common type of carbon steel flange. They are used in high-pressure applications and can handle greater stress than slip-on flanges. Weld neck flanges are easy to install and can be welded or threaded onto a pipe.

Threaded Flanges

Threaded flanges are less common than slip-on or weld neck flanges but are still used in some applications. Threaded flanges are installed by screwing them onto the end of a pipe. They are not as strong as weld neck flanges but can be used in lower-pressure applications.

Blind Flanges

Blind flanges are similar to slip-on flanges but do not have a hole in the centre for a pipe to pass through. Blind flanges seal off the end of a pipe or other component in a piping system. Blind flanges can be welded or threaded onto a pipe.

Lap Joint Flanges

Lap joint flanges are similar to slip-on flanges but have a raised face that is used to seal against another lap joint flange. Lap joint flanges are often used in low-pressure applications where a welded or threaded connection is not required.

Functions of Carbon Steel Flanges

Carbon steel flanges have several functions, making them useful in various applications. Firstly, they combine two pipes and provide an air-tight seal for the ends. Secondly, they allow for easy disassembly and reassembly when needed. Thirdly, they offer versatility in accommodating different pressures and temperatures thanks to their low-temperature ratings. Finally, carbon steel flanges provide structural support for plates and other objects while being highly cost-effective because of their durability and long lifespan.


Carbon steel flanges are incredibly versatile and have a multitude of uses in numerous applications. They offer the most economical solution as they are strong, sturdy, and easy to install. All this makes them the ideal choice for many applications in nearly any industry. Depending on the specific application, there are several types of carbon steel flanges that can be used offering various levels of strength, durability, and pressure ratings. With such a variety to choose from selecting the right one for your project is essential for your success. It is important to research what you need before you make your selection because choosing the correct type or model can save you time and money during installation or production. Taking all these points into consideration will ensure that all your needs are met with ease and effectiveness so that your project goes off without any hitches!
