The elliptical head 1600 mm is a medium industrial size for vessels, process equipment and tanks. Treat it as part of the equipment design rather than an independent metal blank.
At D = 1600 mm, h2 = 400 mm. Calculations consider shell thickness, medium, pressure, temperature, material and welded joint requirements.

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 1600 mm
Manufacturing 1600 mm requires consistent geometry around the circumference. Agree shell parameters and inspection before production to prepare the component for assembly.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 1600 mm;
- elliptical dish depth h2 = 400 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 1600 mm
Applications for 1600 mm include LPG tanks and BUON oil dehydration units.
- LPG storage tanks
- BUON oil dehydration units
- other vessels where D = 1600 mm is specified in the design documentation.
BUON diameter follows the vessel design, while LPG tank diameter follows tank documentation. These links describe elliptical head applications rather than universal dimensions.
GOST 6533-78 — 1600 mm
For the catalogue elliptical profile of diameter 1600 mm, dish depth h2 = 400 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 1600 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 1600 mm
Before quoting 1600 mm, provide the main operating conditions and shell connection drawing.
