ASME/ANSI B16.5, B16.47 Socket Weld Flange Manufacturers
A Socket Weld Flange is a type of flange used to connect pipes in high-pressure systems, typically in smaller sizes (up to 2 inches). It features a socket that allows the pipe to be inserted into the flange, where it is then welded in place. This design provides a strong and leak-proof connection, making socket weld flanges ideal for use in systems where space is limited and where resistance to pressure and temperature is required. Commonly used in industries like oil and gas, petrochemical, and power generation, these flanges are available in various materials such as stainless steel, carbon steel, and alloy steel. Socket weld flanges offer a secure, durable connection and are favored for their ease of installation and reliable performance in high-stress environments.
Ample Alloys is a leading manufacturer, supplier, and exporter of high-quality Socket Weld Flanges designed to meet the demands of various industries. Known for their commitment to quality, We offers socket weld flanges made from premium materials, ensuring durability and reliability even in high-pressure environments.
