Flanged conical head 3300 mm — profile diagram

Cylindrical pressure vesselsFlare separators (FS)

Flanged conical head 3300 mm. The cone connects the large diameter D to the small diameter d; the formed edge provides the transition to the cylindrical section.

Germes-Ural manufactures flanged conical heads of diameter 3300 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 3300 mm

Cold forming and flanging of dished ends

For the large diameter 3300 mm, the catalogue specifies d ≥ 600 mm, α 80–150° and H ≤ 1300 mm. These limits are checked as one complete profile, including knuckle radius r = 50–200 mm.

  • 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 3300 mm

Specify the operating requirements for the equipment: Heads for cylindrical pressure vessels, Heads for flare separators (FS). The size and profile are selected according to the equipment design.

Cone angle α, small-end diameter d and overall height H are geometrically linked. Catalogue values should not be selected independently: the complete profile and its suitability are checked by the equipment design.

Vessel equipment applications
Dished-end profile and manufacturing requirements

Profile 3300 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.

Surface preservation

Surface condition of 3300 mm can affect subsequent vessel preparation. Specify cleaning, machining marks and storage protection in advance, consistent with the material and medium.

For flanged conical heads 3300 mm, include this requirement in the technical specification together with the profile dimensions: α = 80–150°, d ≥ 600 mm.

Frequently asked questions

How should surface requirements for 3300 mm be specified?

Specify the side to be processed, permitted defects, inspection method and cleaning or protection requirements. A general statement of a clean surface is insufficient.

How is the allowable operating pressure determined?

No. The catalogue interval describes a production range; suitability of an angle depends on the construction, loads and calculations. Include D, d, α, H and a drawing of the transitions in the enquiry.

What thickness is available for flanged conical head 3300 mm?

The published table lists thicknesses of 4–22 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 flanged conical head 3300 mm?

The lead time is confirmed after the specification is agreed, taking into account blank availability, batch size and processing operations.

Packaging of dished ends

Delivery of heads 3300 mm

Packaging and transport are selected for the actual height, weight and batch quantity. For the large diameter 3300 mm, the catalogue specifies d ≥ 600 mm, α = 80–150° and H ≤ 1300 mm. These limits are confirmed as one profile, including knuckle radius r = 50–200 mm.

Prepared edges and surfaces are protected during transport. Include unloading conditions and any special packaging requirements in the order.
