WELDO FLANGES

What are Weldo Flanges?


Weldo flanges are a type of pipe flange used in welding applications. They are designed to connect pipes, valves, and other equipment in a secure and leak-proof manner. Weldo flanges are made from high-quality materials such as carbon steel, stainless steel, or alloy steel, ensuring their durability and longevity. These flanges have a raised face or flat face with bolt holes, allowing them to be easily bolted to the adjoining equipment. The welding process involves fusing the Weldo flange to the pipe or equipment, creating a strong and permanent connection.

Weldo flanges work by providing a smooth transition from one pipe or equipment to another. The raised face or flat face of the flange ensures a tight seal when bolted, preventing any leakage of fluids or gases. The welding process further strengthens the connection, making it resistant to high pressure and temperature conditions. Weldo flanges are commonly used in applications where a secure and reliable connection is essential, such as oil and gas pipelines, chemical plants, power generation facilities, and more.

Weldo flanges offer several advantages over other types of flanges. Firstly, their welded connection provides superior strength and durability compared to flanges connected by gaskets or threads. This makes them suitable for high-pressure and high-temperature applications. Additionally, Weldo flanges are highly resistant to corrosion, ensuring a long service life even in harsh environments. Their compact design and ease of installation make them a popular choice among welders and engineers. However, it's important to consider the specific requirements of your project before choosing Weldo flanges, as they may not be suitable for every application. Typ

Advantages of Using Weldo Flanges


Weldo flanges offer numerous advantages that make them a popular choice in the welding industry.

Advantages of using Weldo flanges:

Strength and durability
Weldo flanges provide a strong and permanent connection, making them suitable for high-pressure and high-temperature applications. The welded joint ensures a leak-proof seal, minimizing the risk of fluid or gas leakage.

Corrosion resistance
Weldo flanges are made from high-quality materials such as carbon steel, stainless steel, or alloy steel, which offer excellent resistance to corrosion. This ensures a long service life, even in harsh environments.

Versatility
Weldo flanges are available in various types and sizes, allowing them to be used in a wide range of applications. They can be easily customized to meet specific project requirements.

Easy installation
Weldo flanges are relatively easy to install, especially in comparison to flanges connected by gaskets or threads. The welding process ensures a secure and reliable connection, reducing the risk of assembly errors.

Choosing the right Weldo flange for your project


Selecting the right Weldo flange for your project is crucial to ensure a successful and efficient connection. Here are some factors to consider when choosing a Weldo flange:

Pressure rating
Determine the maximum pressure that the flange will be subjected to in your application. Choose a Weldo flange with a pressure rating that meets or exceeds your requirements.

Temperature range
Consider the operating temperature range of your application. Select a Weldo flange that can withstand the highest temperature without compromising its integrity.

Material compatibility
Ensure that the material of the Weldo flange is compatible with the fluid or gas being transported. Different materials offer varying levels of resistance to corrosion and chemical compatibility.

Size and dimensions Determine the size and dimensions of the pipe or equipment that the Weldo flange will be connected to. Choose a flange that matches the size and dimensions to ensure a proper fit.

Installation method
Consider the ease of installation and the welding process required for the selected Weldo flange. Ensure that you have the necessary welding equipment and expertise to install the flange correctly.

Consulting with a qualified engineer or welding specialist is highly recommended to ensure you choose the right Weldo flange for your specific project requirements. They can provide valuable insights and recommendations based on their expertise and experience.

Applications of Weldo Flanges


Weldo flanges find extensive use in various industries, thanks to their versatility and reliability. Here are some common applications of Weldo flanges:

Oil and gas industry
Weldo flanges are widely used in oil and gas pipelines to connect pipes, valves, and other equipment. Their ability to withstand high pressure, temperature, and corrosive environments makes them an ideal choice for this industry.

Chemical industry
Weldo flanges are commonly used in chemical plants to connect pipes carrying different chemicals. The corrosion resistance of Weldo flanges ensures the safe transport of chemicals without any leakage.

Power generation
Weldo flanges are used in power plants to connect pipes carrying steam, water, or other fluids. Their ability to withstand high temperatures and pressures is essential for the efficient operation of power generation equipment.

Food and beverage industry Weldo flanges are utilized in the food and beverage industry to connect pipes carrying liquids or gases. The hygienic properties of stainless steel Weldo flanges make them suitable for applications where cleanliness is critical.

Construction industry Weldo flanges are used in construction projects for connecting pipes in HVAC systems, plumbing, and other applications. Their strength and durability ensure a secure and long-lasting connection.

These are just a few examples of the many industries that benefit from the use of Weldo flanges. Their wide range of applications is a testament to their versatility and reliability in various challenging environments.

General notes:
  • Dimensions: Top Row in Inches / Bottom Row in millimeters.
  • Root Gap - X - "Space" for welding the O'let is raised off the run pipe to establish proper
    weld gap by placing spacers, e.g. welding rods, under the fitting. This provides a uniform
    welding gap between the curvature of the run and base of fitting.
  • L = Dimensions Center Line of Run Pipe + X (Root Gap) + A (height of Weldolet).
  • Bevelled Ends ASME B16.9 and B16.25.
  • Source comes from Bonney Forge (except the sizes in millimeters).
  • Weldolet® is a registered name. Another often used name is Welding Outlet.
