Top 10 weld neck flange Factory in the world

Introduction to Weld Neck Flanges

Weld neck flanges are a type of pipe flange that are widely used in various industries, including oil and gas, chemical, power generation, and water treatment. They are designed to be welded to the pipe, providing a strong and reliable connection. The long tapered neck of the weld neck flange gradually transitions the stress from the flange to the pipe, reducing stress concentration and enhancing the overall strength of the joint. This makes them suitable for high - pressure and high - temperature applications. Weld neck flanges are available in different materials such as carbon steel, stainless steel, alloy steel, and are manufactured in accordance with various international standards like ASME, API, and DIN.
