Hubbed Slip-On Flanges according to EN 1092-1 PN40 are high-pressure flanges designed to slip over the pipe and are welded on both the inner and outer edges for enhanced strength and leak resistance. The hub adds structural integrity and precise alignment, making these flanges suitable for demanding industrial applications. Complying with the EN 1092-1 standard, the PN40 pressure rating means these flanges are built to withstand operating pressures of up to 40 bar. They are commonly used in high-pressure systems such as oil & gas, petrochemical, power generation, and steam pipelines. Available in various sizes and materials, including carbon steel and stainless steel, they ensure reliability in critical piping systems.
