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 3300 mm

Cold forming and flanging of dished ends

For 3300 mm, inspection after forming and before delivery is particularly important. Geometry must be preserved through storage and transport until assembly.

Checks during manufacturing include:

  • initial blank thickness and condition;
  • Diameter D = 3300 mm;
  • elliptical dish depth h2 = 825 mm;
  • knuckle geometry and uniformity;
  • component ovality;
  • surface and edge condition.

Applications of the elliptical head 3300 mm

Applications for 3300 mm include industrial separators and fire water tanks, subject to the equipment design.

This large equipment is designed individually. The link describes elliptical head applications without assigning a universal D to each model.

Vessel equipment applications
Dished-end profile and manufacturing requirements

GOST 6533-78 — 3300 mm

For the catalogue elliptical profile of diameter 3300 mm, dish depth h2 = 825 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 3300 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 3300 mm

For D = 3300 mm, agree responsibility for technical acceptance and logistics before production starts.

  • thickness S and material grade;
  • required straight flange height h1;
  • equipment application, medium, pressure and temperature;
  • edge preparation and welded joint requirements;
  • customer contact and technical acceptance requirements;
  • handover to the carrier and unloading conditions at the site;
  • drawing or technical specification for a project-specific configuration.
