Flat flanged head 2000 mm. The flat central section joins the cylindrical straight flange through a formed knuckle.
Germes-Ural manufactures flat flanged heads of diameter 2000 mm to the agreed drawing. Profile and thickness are selected for the equipment; applicable GOST requirements are considered in the project and order.

The table retains the company’s published dimensions. The combination of size, material and loads is agreed against the drawing; the thickness range does not establish an allowable operating pressure.
Manufacturing heads 2000 mm
For the flat head 2000 mm, checks cover the central surface and the knuckle r = 50 mm. Straight flange length and weld preparation are specified together with thickness and joint design.
- Mating diameter and tolerances
- Agreed profile and smooth transitions
- Finished component thickness
- Straight flange and weld edge preparation
- Compliance of the material with the specification
Applications of heads 2000 mm
Specify the operating requirements for the equipment: Heads for clarification filters, Heads for industrial separators. The size and profile are selected according to the equipment design.
The central flat section is checked for flatness, and the formed edge for radius and thickness. Allowable pressure cannot be assigned from appearance alone: the calculation depends on restraints, loads, openings and dimensions.
Profile 2000 mm and requirements GOST
GOST 34347-2017 sets general technical requirements for welded steel vessels. Calculations for cylindrical and conical components, dished and flat heads use the applicable provisions of GOST 34233.2-2017 and the project documentation.
The catalogue shows the company’s production range. It does not extend the scope of the standards or replace allowable pressure calculations. The profile, radii, heights and finished thickness are agreed in the technical specification and drawing.
Limit of the r = 50 mm configuration
In the current size range, 2000 mm ends the group with knuckle radius 50 mm. This is a production configuration rather than a universal standard rule. Other transitions require separate agreement.
For flat flanged heads 2000 mm, include this requirement in the technical specification together with the profile dimensions: r = 50 mm; s = 3–18 mm.

Frequently asked questions
Which r is specified for 2000 mm?
The published card specifies r = 50 mm. Other geometry is not inferred from neighbouring sizes; an agreed drawing is required.
Can a dished head be replaced by a flat head of the same diameter?
A replacement requires a design and calculation review. A flat head carries loads differently; equal D and s values do not establish equivalent strength or stiffness.
What thickness is available for flat flanged head 2000 mm?
The published table lists thicknesses of 3–18 mm. Thickness is selected by calculation for the medium and loads. Material, allowances and the condition after forming are recorded in the documentation.
What information is needed for a quotation?
Provide the drawing, material grade, thickness, quantity, operating conditions, edge preparation, openings and inspection requirements. Include the delivery destination and unloading conditions.
What is the lead time for flat flanged head 2000 mm?
The lead time is confirmed after the specification is agreed, taking into account blank availability, batch size and processing operations.
Delivery of heads 2000 mm
Packaging and transport are selected for the actual height, weight and batch quantity. For the flat head 2000 mm, inspection covers the central surface and knuckle r = 50 mm. Straight flange length and weld preparation are specified with the thickness and joint design.
Prepared edges and surfaces are protected during transport. Include unloading conditions and any special packaging requirements in the order.
