ASME B16.5 Class 150/300 Forged Steel Socket Weld Flange - China Suppliers & Factory for High-Pressure Pipelines

A socket weld flange is an essential component for connecting pipelines efficiently, and it is particularly favored for its simple welding technology and high sealing performance. Manufactured in China, these flanges are designed with a socket structure that precisely fits the outer diameter of the pipeline, making installation straightforward. When the pipeline is inserted into the socket hole, the annular gap is securely welded, which minimizes stress concentration and enhances the durability of the connection, Ideal for small-diameter pipelines with a nominal diameter not exceeding 80mm, socket weld flanges are optimal for high-pressure, corrosive environments, and applications requiring cleanliness—such as chemical processing, petroleum distribution, and high-pressure systems. This design prevents welding slag from entering the pipeline, ensuring a reliable and leak-proof connection, As leading suppliers and factory producers in China, we emphasize the importance of strict control over the insertion depth during installation. Additionally, flaw detection following welding is essential to validate the quality of the connection, **Quick Details**, | **Parameter** | **Details** |, |---------------------|----------------------------------------------------------------------------------------------|, | Outside Diameter | 1/2~3 (DN15~DN80) |, | Class | PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, PN100 Class 150, 300, 600, 900, 1500, 2500lb |, | Standards | EN 1092-1, ANSI/ASME B16.5, DIN2633-DIN2634, JIS B2220, ASME B16.47 Series A/B |
