What is WNRF Flanges ?
A WNRF Flange, also known as a Weld Neck Flange, is a type of flange that is designed to be welded to a pipe. It has a long tapered neck that gradually transitions to the diameter of the pipe. The design of the WNRF Flange makes it ideal for high-pressure and high-temperature applications.
Materials Used in Manufacturing WNRF Flanges can be manufactured using various materials, including carbon steel, stainless steel, and alloy steel. The choice of material will depend on the project’s specific requirements, including the application’s temperature and pressure.
Advantages of Using WNRF Flanges
There are several advantages to using WNRF Flanges in your project. Their design makes them ideal for high-pressure and high-temperature applications, ensuring your project is safe and reliable. Additionally, the welding process used to attach the flange to the pipe creates a strong and permanent connection. Finally, WNRF Flanges are versatile and can be used in various applications, including oil and gas, chemical processing, and power generation. WNRF Flange Dimensions and Standards WNRF Flanges are available in various sizes and dimensions, and selecting the correct size for your project is essential.
Various standards govern the manufacturing of WNRF Flanges, including ASME/ANSI, API, and DIN standards. Our team can help you select the correct size and standard for your project.
Proper installation of WNRF Flanges is essential to ensure the safety and reliability of your project. Our team can guide you on the correct installation procedures to ensure your project is successful.
These flanges got bored in such a way that it can be easily matched with the inside diameter of fitting or mating pipe so there will not be any restriction of flow. This will prevent not only the turbulence but also reduces the erosion at the joints. They also offer excellent distribution via a tapered hub and can be radiograph easily for flaw detection.
