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 1700 mm

Cold forming and flanging of dished ends

Forming 1700 mm includes checks of final diameter and height distribution across the section, supporting shell assembly and a defined weld position.

Checks during manufacturing include:

  • initial blank thickness and condition;
  • Diameter D = 1700 mm;
  • elliptical dish depth h2 = 425 mm;
  • knuckle geometry and uniformity;
  • component ovality;
  • surface and edge condition.

Applications of the elliptical head 1700 mm

Applications include gas-liquid separators and fire water tanks.

Both applications use vessels but have different pressure, medium and material requirements. The actual D = 1700 mm configuration is agreed separately.

Vessel equipment applications
Dished-end profile and manufacturing requirements

GOST 6533-78 — 1700 mm

For the catalogue elliptical profile of diameter 1700 mm, dish depth h2 = 425 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 1700 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 1700 mm

For 1700 mm, state profile requirements and allowable deviations where defined by the engineering documentation.

  • thickness S and material grade;
  • required straight flange height h1;
  • equipment application, medium, pressure and temperature;
  • edge preparation and welded joint requirements;
  • geometry tolerances specified in the drawing;
  • profile inspection requirements after forming;
  • drawing or technical specification for a project-specific configuration.
