Weld neck flanges as per EN 1092-1 PN 400 are built for the most demanding high-pressure applications, offering superior strength, safety, and long-term performance. With a long tapered hub, these flanges ensure smooth stress distribution and a secure butt-welded connection, critical for extreme pressure environments. Manufactured to the highest precision in accordance with EN 1092-1 standards, they are ideal for use in power plants, high-pressure steam systems, oil & gas, and heavy-duty industrial operations where maximum reliability is essential.
