What is Flangeolet? Uses and Applications


When it comes to pipelines and high-pressure applications, proper fittings and connections are essential for a safe and efficient system. That’s where Flangeolet comes in. This unique fitting is a type of branch connection that can be used in a wide range of applications. In this blog post, we’ll explore what Flangeolet is, its various uses and applications, and how to use it.

What is Flangeolet?

Flangeolet is a type of speciality fitting used to connect pipes with different diameters or branch off pipelines. It is a combination of a Weldolet and a Flange, which makes it unique and versatile. Flangeolets come in different sizes and materials, including carbon steel, stainless steel, and nickel alloys. They are typically used in high-pressure applications that require a strong and durable connection.

Uses and Applications of Flangeolet

One of the most common applications of Flangeolets is in the oil and gas industry. They connect pipelines in refineries, offshore drilling platforms, and other oil and gas facilities. They are also used in chemical and power plants and other industrial applications requiring a reliable and efficient piping system. Flangeolets are also used in HVAC systems, pharmaceuticals, and food processing plants.

How to Use Flangeolet

Using Flangeolet requires some expertise, but it’s simple. It is important to select the right size and material for your application. Flangeolets are usually welded onto the main pipeline, and the Flange end is bolted onto the branch pipe. The Weldolet end of the Flangeolet is welded onto the main pipe and branches off into a smaller pipe. Following the manufacturer’s installation instructions is important to ensure a safe and effective connection.

Advantages of Flangeolet

There are several advantages of using Flangeolet over other types of branch connections. Firstly, it reduces the need for welding, which saves time and money. Secondly, it eliminates the need for a flange joint, which reduces the risk of leaks and enhances the system’s overall integrity. Lastly, Flangeolets provide a smooth and seamless connection, which minimizes turbulence and pressure drop.


Flangeolet is a versatile and reliable fitting that is used in a wide range of applications. It is a combination of a Weldolet and a Flange, and it is used to connect pipelines with different diameters or to branch off pipelines. Flangeolets are used in different industries, including oil and gas, chemical plants, power plants, and HVAC systems. It has various advantages over other branch connections, including reducing the need for welding, eliminating leaks, and providing smooth and seamless connections. Proper installation of Flangeolet is essential for a safe and efficient piping system, and following the manufacturer’s installation instructions is always recommended.
