About Weldo Flanges :-
Weldo Flanges, also known as Weldoflanges or Nipo Flanges, are a unique type of flange that combines the features of a welding neck flange and a weldolet. This dual functionality allows Weldo Flanges to serve as both a branch connection and a flange connection, providing a streamlined solution for connecting pipes at an angle, usually at 90 degrees. This flange type is particularly useful in applications where a branch pipe needs to be connected to a main run pipe with minimal welding and structural impact.
The Weldo Flange has a hub with a bore that matches the branch pipe size and is designed to be welded directly to the branch pipe, making it part of the overall piping structure. This design creates a smooth, gradual transition that evenly distributes stress across the joint, minimizing potential weak points and reducing the likelihood of leaks. The flange’s face can be either raised face (RF) or ring-type joint (RTJ), depending on the pressure and sealing requirements of the system.
One of the primary advantages of Weldo Flanges is that they simplify installation in branching applications by reducing the number of welds and components needed to connect a branch pipe to a main pipeline. This simplification enhances the integrity of the connection and decreases installation time, making it a cost-effective option for projects requiring numerous branch connections. Additionally, their streamlined design helps to reduce turbulence and pressure drop within the piping system, promoting better flow and system efficiency.
Weldo Flanges are commonly used in industries such as oil and gas, petrochemical, power generation, and water treatment, where reliable branch connections are essential. They are designed to meet industry standards such as ASME B16.5 for smaller sizes or ASME B16.47 for larger sizes, ensuring compatibility with standard piping systems and materials.
In summary, Weldo Flanges provide a versatile and efficient solution for branch connections, combining the strength of a welding neck flange with the convenience of a weldolet. Their ability to reduce the number of components and welds in a system makes them ideal for applications that demand both durability and ease of installation in critical branching points.
