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 2000 mm
Forming 2000 mm requires uniform work around a large circumference. Inspect the component before movement: incorrect storage or securing can damage finished geometry.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 2000 mm;
- elliptical dish depth h2 = 500 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 2000 mm
Applications for the two-metre size include oil buffer degassers and fire water tanks.
- BDN oil buffer degassers
- Fire water tanks
- other vessels where D = 2000 mm is specified in the design documentation.
BDN unit diameter follows its design; tank diameter follows its construction and calculations. State the application in the initial requirements.
GOST 6533-78 — 2000 mm
For the catalogue elliptical profile of diameter 2000 mm, dish depth h2 = 500 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 2000 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 2000 mm
For D = 2000 mm, plan acceptance as well as manufacturing: unloading location, lifting and storage before assembly.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- unloading and handling conditions at the customer’s site;
- temporary protection and storage requirements before installation;
- drawing or technical specification for a project-specific configuration.

Increasing diameter to 2000 mm does not automatically determine a thicker wall. Thickness follows vessel calculations and the selected material properties.
Quality inspection of heads 2000 mm
The main component parameters are checked before delivery. After geometry measurements, the component enters storage on supports that do not deform the edge.
- compliance of diameter D = 2000 mm;
- elliptical dish depth h2 = 500 mm;
