Carbon steel weld neck flange is frequently utilized in industrial settings and is known for its adaptability, dependability, and ease of installation and replacement. This article will focus on weld neck flanges, discussing their potential uses across various applications, the welding procedure employed, and the diverse variations available.

Carbon steel weld neck flanges are extensively utilized for connecting pipes in pipe fittings. They are specially designed to establish a reliable connection between two pipes or tubing, besides linking various valves and components in a piping system. Such weld neck flanges commonly find their application in oil rigs, chemical plants, and water lines.

Materials of Cabon Steel Weld Neck Flange

A range of materials is applicable for carbon steel weld neck flange, as required by standards, with the highest level of quality established by ASTM and ASME regulations. The thickness and internal diameter of the flange must correspond to the size of the intended pipe.
