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 2900 mm

Cold forming and flanging of dished ends

For 2900 mm, agree documentation first, then form and inspect the profile before transport preparation. This sequence reduces the risk of damaging an accepted component.

Checks during manufacturing include:

  • initial blank thickness and condition;
  • Diameter D = 2900 mm;
  • elliptical dish depth h2 = 725 mm;
  • knuckle geometry and uniformity;
  • component ovality;
  • surface and edge condition.

Applications of the elliptical head 2900 mm

Related equipment includes filter separators and EP/EPP drainage tanks, with different elliptical head applications.

The 2900 mm size is used where specified by the equipment design. These links describe the relevant equipment classes.

Vessel equipment applications
Dished-end profile and manufacturing requirements

GOST 6533-78 — 2900 mm

For the catalogue elliptical profile of diameter 2900 mm, dish depth h2 = 725 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 2900 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 2900 mm

For D = 2900 mm, provide the destination and transport restrictions early so logistics can be considered before production.

  • thickness S and material grade;
  • required straight flange height h1;
  • equipment application, medium, pressure and temperature;
  • edge preparation and welded joint requirements;
  • exact destination and access restrictions;
  • special packaging or temporary surface protection requirements;
  • drawing or technical specification for a project-specific configuration.
