CS ASTM A105 weld neck flanges provide a strong and reliable connection between pipes or equipment, ensuring leak-free performance in high-pressure systems. The long tapered hub of the weld neck flange adds reinforcement, enhancing the overall strength & durability of the joint.

ASTM A105 carbon steel weld neck flanges have a raised face, which provides a sealing surface & helps prevent leakage. The weld neck design offers reinforcement and allows for easy alignment during installation. These flanges also have a beveled end for seamless welding to the adjoining pipe, ensuring a strong and reliable connection.

ASTM A105 carbon steel weld neck flanges are available in a wide range of sizes, typically ranging from ½ inch to 60 inches in diameter. To accommodate different operating conditions & system requirements, they can be obtained in various pressure classes, such as 150, 300, 600, 900, 1500, and 2500.
