Features of the shallow dished profile
A shallow dished head has a low-profile spherical crown and a formed transition to the cylindrical straight flange. D, R, r and heights define one profile, so changes require drawing agreement. The catalogue lists 38 diameters from 600 to 4300 mm, with thicknesses 3–22 mm.
The profile follows technical specifications and customer documentation. Applicable GOST 34347-2017 requirements are considered for welded steel vessels, while calculation methods follow construction and service conditions. Submit material, medium, pressure and temperature with the order.
Applications and ordering
Initial requirements are described in head applications: Heads for air receivers, Heads for horizontal air receivers, Heads for clarification filters, Heads for cylindrical pressure vessels. Suitability of the shallow dished profile is confirmed by the equipment design; these links provide application information.
A quotation requires diameter, selected radii, thickness, material, quantity, edge preparation and inspection requirements. Germes-Ural agrees manufacturing and delivery against the order documentation.
