ASTM A105 carbon steel weld neck flanges are crucial components in high-pressure and high-temperature piping systems, designed to provide a robust and reliable connection between pipes, valves, and other equipment. Made from ASTM A105 carbon steel, these flanges feature a tapered neck that is welded directly to the pipe, creating a strong and smooth transition that reduces stress concentrations. This design enhances the flange’s ability to handle high pressures and temperatures, making it suitable for demanding industrial applications. Commonly used in sectors such as oil and gas, petrochemical, and power generation, ASTM A105 weld neck flanges are essential for maintaining the integrity and functionality of piping systems.
