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 3000 mm

Cold forming and flanging of dished ends

Forming 3000 mm requires a uniform profile across a large surface and consistent knuckle geometry around the circumference. After inspection, support and handling consider its overall size.

Checks during manufacturing include:

  • initial blank thickness and condition;
  • Diameter D = 3000 mm;
  • elliptical dish depth h2 = 750 mm;
  • knuckle geometry and uniformity;
  • component ovality;
  • surface and edge condition.

Applications of the elliptical head 3000 mm

Applications for 3000 mm include industrial separators and LPG storage tanks.

The equipment design specifies the type, diameter and thickness. D = 3000 mm is manufactured against the agreed documentation.

Vessel equipment applications
Dished-end profile and manufacturing requirements

GOST 6533-78 — 3000 mm

For the catalogue elliptical profile of diameter 3000 mm, dish depth h2 = 750 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 3000 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 3000 mm

For 3000 mm, include the delivery city and unloading information with the technical parameters.

  • thickness S and material grade;
  • required straight flange height h1;
  • equipment application, medium, pressure and temperature;
  • edge preparation and welded joint requirements;
  • delivery city and region for preliminary logistics planning;
  • component quantity and available unloading method at the site;
  • drawing or technical specification for a project-specific configuration.

Geometry and quality inspection of dished ends

Quality inspection of heads 3000 mm

The main component parameters are checked before delivery. For D = 3000 mm, checks cover diameter, h2, h1, ovality, surface and edge. These parameters must be preserved during loading.

  • compliance of diameter D = 3000 mm;
  • elliptical dish depth h2 = 750 mm;
  • metal thickness;
  • ovality and knuckle geometry;
  • surface and edge quality;
  • compliance with GOST, technical specifications or the drawing.
