The elliptical head 2200 mm is a large vessel component where small relative deviations become significant absolute differences. Diameter and ovality inspection are key acceptance checks.
The elliptical dish depth at D = 2200 mm is 550 mm. Other parameters depend on thickness, material and equipment documentation.

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 2200 mm
Inspection of 2200 mm uses several directions to assess ovality and profile uniformity, particularly before delivery to a separate assembly facility.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 2200 mm;
- elliptical dish depth h2 = 550 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 2200 mm
Applications for 2200 mm include gas-liquid separators and underground LPG tanks.
- Gas-liquid centrifugal separators
- Underground LPG tanks
- other vessels where D = 2200 mm is specified in the design documentation.
Both applications require a sealed construction, but operating conditions and material requirements differ. The design specifies the configuration.
GOST 6533-78 — 2200 mm
For the catalogue elliptical profile of diameter 2200 mm, dish depth h2 = 550 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 2200 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 2200 mm
When ordering 2200 mm, record allowable ovality and the mating diameter measurement method separately.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- allowable ovality according to the design documentation;
- mating diameter inspection method for acceptance;
- drawing or technical specification for a project-specific configuration.

Quality inspection of heads 2200 mm
The main component parameters are checked before delivery. For D = 2200 mm, measure in several directions and record the actual geometry as required by the order.
- compliance of diameter D = 2200 mm;
- elliptical dish depth h2 = 550 mm;
- metal thickness;
- ovality and knuckle geometry;
- surface and edge quality;
- compliance with GOST, technical specifications or the drawing.
