According to ASME, if fluid is lethal service (Toxic, dangerous fluid), slip on flange(fillet welding) is not allowed.
PED or EN code have similar rules?
PED is not a design code. EN 13445 doesn’t have such requirement either. There are however few other service driven (mainly due to temperature) limitations but they’re linked to fluid groups or such.
