Selection and ordering notes
The EN 1092-1 type 11 weld neck flange is the metric counterpart of the ASME weld neck design. The hub provides a smooth stress transition and the type is used safely in higher PN classes.
EN flanges have a different bolt circle from ASME types, so the mating flange must share the same standard. At PN 160 and above, material, heat treatment and inspection requirements are defined separately. See flange types guide for the details.
