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 2600 mm
For diameter 2600 mm, the crown radius R = 2600 mm is combined with knuckle radius r = 100 mm. Dish depth and straight flange length are checked against the same drawing revision.
- 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 2600 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.
A crown radius R = D does not make a domed flanged head interchangeable with a shallow dished or torispherical head. Knuckle radius, heights and thickness after forming must also be compared.
Profile 2600 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.
Order specification
For 2600 mm, agree the supply scope: formed head, edge machining, openings, inspection and documentation. These operations do not follow automatically from the product name. A clear specification makes the quotation comparable with assembly needs.
For domed flanged heads 2600 mm, include this requirement in the technical specification together with the profile dimensions: R = 2600 mm; r = 100 mm.

Frequently asked questions
What information is needed for a quotation?
The work is recorded in the agreed specification. State the material, profile, processing, inspection, quantity and required documents.
How does this profile differ from other head types?
The published domed flanged profile uses R = D, whereas the shallow dished profile uses R greater than D. Even at the same diameter, head height and mating geometry must be checked against the drawing.
What thickness is available for domed flanged head 2600 mm?
The published table lists thicknesses of 3–22 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 domed flanged head 2600 mm?
The lead time is confirmed after the specification is agreed, taking into account blank availability, batch size and processing operations.
Delivery of heads 2600 mm
Packaging and transport are selected for the actual height, weight and batch quantity. At diameter 2600 mm, crown radius R = 2600 mm is combined with knuckle radius r = 100 mm. Dish depth and straight flange length are checked against the same drawing revision.
Prepared edges and surfaces are protected during transport. Include unloading conditions and any special packaging requirements in the order.
