A nipo flange is a type of pipe connector, typically used for 90 degree branch pipeline connections. This forged steel connector is made by welding a nipolet onto a branch pipe flange. Nipoflanges are available in a variety of sizes and grades, and the standard specification is ASME B16.
Weldo flanges and Nipo flanges are specialized types of pipe flanges used in piping systems for various applications. Let's explore each type:

Weldo Flange:
Definition: A Weldo flange, also known as a Weld Neck Outlet flange, is a type of flange designed to be welded directly to the pipe. It is characterized by a long, tapered neck that extends from the flange and is welded to the pipe, providing excellent structural strength and durability.
Design: The Weldo flange has a raised face and is typically used in high-pressure and high-temperature applications. The welding neck ensures a smooth transition of stress from the flange to the pipe. This design helps in reducing the stress concentration at the base of the flange, making it suitable for critical applications.
Applications: Weldo flanges are commonly used in industries such as oil and gas, petrochemical, chemical, and power plants where high pressures and temperatures are encountered. They are preferred in situations where structural integrity is crucial.
Nipo Flange:
Definition: A Nipo flange, short for Nipple Outlet flange, is a type of flange that includes a welded nipple, or extension, on the flange face. This nipple can be threaded or welded to facilitate the connection of pipes, valves, or other components.
Design: Nipo flanges are designed for applications where a connection for a branch pipe is required. The nipple extension provides a convenient point for attaching additional piping components. Like other types of flanges, they come in various sizes and pressure classes to suit different requirements.
Applications: Nipo flanges are commonly used in piping systems where branching or tapping into the main pipeline is necessary. They find applications in industries such as chemical processing, refineries, and other fluid handling systems.
