Elliptical head 2300 mm — profile diagram

Industrial separatorsAir receivers

The elliptical head 2300 mm is intended for large tank and separator equipment. Manufacturing depends on accurate initial shell dimensions, thickness and straight flange requirements.

At D = 2300 mm, h2 = 575 mm. Standard and project-specific configurations can be agreed in the drawing.

The straight flange height h1 is selected by diameter and thickness from GOST 6533-78, Table 2 (internal basic diameter). Sizes and thicknesses absent from that table, including 3 mm, require an agreed drawing or technical specification. h2 = D/4 for this elliptical profile.

Manufacturing elliptical heads 2300 mm

Cold forming and flanging of dished ends

For 2300 mm, check an existing shell’s geometry before forming to avoid discrepancies between the nominal drawing size and actual mating diameter.

Checks during manufacturing include:

  • initial blank thickness and condition;
  • Diameter D = 2300 mm;
  • elliptical dish depth h2 = 575 mm;
  • knuckle geometry and uniformity;
  • component ovality;
  • surface and edge condition.

Applications of the elliptical head 2300 mm

Related applications include industrial separators and underground fire water tanks.

Separators and underground tanks have different design models, requiring project-specific head selection.

Vessel equipment applications
Dished-end profile and manufacturing requirements

GOST 6533-78 — 2300 mm

For the catalogue elliptical profile of diameter 2300 mm, dish depth h2 = 575 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 2300 mm with reference to GOST 6533-78, GOST 34347-2017, GOST 34233.2-2017, calculations and the technical specification. Non-standard parameters are recorded in the agreed drawing.

Ordering requirements for a head 2300 mm

For 2300 mm intended for an existing shell, include actual shell measurements with the drawing.

  • thickness S and material grade;
  • required straight flange height h1;
  • equipment application, medium, pressure and temperature;
  • edge preparation and welded joint requirements;
  • actual shell measurements for a replacement head or existing shell;
  • assembly restrictions at the site;
  • drawing or technical specification for a project-specific configuration.
