High-neck flange offering in Haokun’s product catalog.
The supplier lists high-neck flanges as a separate product form. Use the actual pipe or equipment connection drawing to specify the neck, bore and mating face. Confirm material, end preparation and machining dimensions with Haokun for that selected configuration; the repeated general flange description does not establish an item-specific pressure or temperature rating.
