Weldo Flange Stockist
A weldo flange, also known as a weld neck or welding neck flange, is a vital component in piping systems and pressure vessels. It plays a crucial role in connecting pipes and providing a leak-free, high-strength joint. The term “weldo” is a colloquialism used in some regions, and the more common term is “weld neck” or “welding neck” flange.
A weldo flange has a distinct design that sets it apart from other types of flanges. It features a long, tapered neck that extends from the flange hub. This neck is designed for welding directly to the pipe. The beveled end of the neck provides an optimal angle for welding, ensuring a secure and robust connection. This design allows for easy radiographic inspection of the weld, making it a preferred choice for applications where weld quality and integrity are critical.

The primary purpose of a weldo flange is to provide a connection point between two pipes or between a pipe and a pressure vessel, such as a tank or boiler. It is commonly used in high-pressure and high-temperature applications, where a reliable and leak-free joint is essential. The smooth transition from the flange to the pipe reduces stress concentrations and helps maintain the structural integrity of the system.
Weldo flanges come in various sizes, pressure ratings, and materials to suit different applications. Common materials include carbon steel weldo flanges, stainless steel weldo flanges, and alloy steel weldo flanges, with the choice of material depending on the specific requirements of the system and the conveyed fluids.
One of the main advantages of weldo flanges is their ability to withstand high pressure and temperature conditions, making them suitable for applications in the oil and gas industry, chemical processing, and power generation. Their robust design and secure welding connection make them a reliable choice for critical systems.
