The elliptical head 3200 mm is a large component whose shell mating accuracy is critical. Adjusting a finished shell or head of this size at assembly is costly and time-consuming.
At D = 3200 mm, h2 = 800 mm. Agree mating diameter, thickness, h1, material and tolerances before production.

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 3200 mm

For 3200 mm, compare the head and shell drawings in advance. Manufacturing inspection then confirms the agreed mating geometry.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 3200 mm;
- elliptical dish depth h2 = 800 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 3200 mm
Applications for 3200 mm include BUON oil dehydration units and LPG tanks.
- BUON oil dehydration units
- LPG storage tanks
- other vessels where D = 3200 mm is specified in the design documentation.
This illustrates elliptical head applications in oil and gas equipment; the design determines the required D.


GOST 6533-78 — 3200 mm
For the catalogue elliptical profile of diameter 3200 mm, dish depth h2 = 800 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 3200 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 3200 mm
For 3200 mm, include the shell drawing or at least a checked mating dimension with tolerances.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- drawing of the mating shell or checked mating dimension;
- joint tolerances specified by the equipment design;
- drawing or technical specification for a project-specific configuration.

For BUON units and LPG tanks, material is selected for the medium, pressure and temperature. Large components require an exact specification of the initial steel.

Quality inspection of heads 3200 mm
The main component parameters are checked before delivery. The mating geometry must match the shell: at D = 3200 mm, a small relative deviation can produce a significant difference in millimetres.
- compliance of diameter D = 3200 mm;
- elliptical dish depth h2 = 800 mm;
- metal thickness;
- ovality and knuckle geometry;
- surface and edge quality;
- compliance with GOST, technical specifications or the drawing.
