ANSI/ASME B16.5 and B16.47 Weldoflange

What is Weldoflange?

A Weldoflange is a specialized type of flange used in piping systems to create a reinforced branch connection. It is designed to simplify the process of adding a branch pipe to the main pipeline. The term "Weldoflange" is a combination of "weld" and "flange," indicating its purpose and construction.

The Weldoflange design provides a strong and reliable solution for branching off from a main pipeline while offering the convenience of a flanged connection for easy integration into the overall piping system. It is essential to select the appropriate pressure class, material, and dimensions based on the specific requirements of the application and industry standards.

key features and characteristics of a Weldoflange

1. Branch Connection: The primary function of a Weldoflange is to provide a branch connection in a piping system. It allows for the branching off of a smaller pipe or tube from the main pipeline.

2. Welded Connection: The Weldoflange has a welded neck that is directly attached to the main pipe through welding. This welded connection ensures strength, integrity, and a leak-resistant joint.

3. Flanged End: The other end of the Weldoflange features a standard flange. This flanged end allows for a secure connection to another flanged component, such as a valve, pump, or another section of piping.

4. Materials: Weldoflanges are typically available in various materials, including carbon steel, stainless steel, and alloy steel. The material selection depends on factors such as the nature of the transported fluid, operating conditions, and corrosion resistance requirements.

5. Pressure Class: Weldoflanges come in different pressure classes or pressure ratings, indicating the maximum working pressure they can withstand. Common pressure classes include Class 150, Class 300, Class 600, and higher, depending on the application's pressure requirements.

6. Standardization: Weldoflanges are manufactured according to industry standards, such as ASME (American Society of Mechanical Engineers) or other relevant standards. These standards define the dimensions, materials, and other specifications to ensure compatibility and consistency in piping systems.

7. Versatility: Weldoflanges are versatile components that find applications in various industries, including oil and gas, petrochemicals, chemical processing, and other sectors where branch connections are required.

The Two Main Components of A Weldoflange Joint Are?

1. Weld Neck (Welded Neck):

   • The weld neck is the part of the Weldoflange that connects directly to the main pipeline through welding. It is a protruding, tapered section designed to be welded to the pipe. This welded connection provides strength, stability, and integrity to the joint.

2. Flanged End:

   • The flanged end is the opposite side of the Weldoflange from the weld neck. It features a standard flange with bolt holes, allowing for a secure connection to another flanged component, such as a valve, pump, or another section of piping. The flange provides a standardized interface for easy assembly and disassembly. The connection at the flanged end ensures compatibility with other components in the piping system.
