The elliptical head 1900 mm is used in medium and large vessels where the head must match the shell and process conditions. A working drawing is particularly useful for non-standard projects.
For D = 1900 mm, h2 = 475 mm. Manufacturing can follow GOST 6533-78 or agreed documentation with individual parameters.

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 1900 mm

For 1900 mm, profile repeatability over a large surface is important. Matching sets are inspected by comparing the key geometry parameters across the batch.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 1900 mm;
- elliptical dish depth h2 = 475 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 1900 mm
Applications for 1900 mm include filter separators and EP/EPP drainage tanks.
- Filter separators and coalescing filters
- EP and EPP drainage tanks
- other vessels where D = 1900 mm is specified in the design documentation.
Filtration equipment and drainage tanks have different purposes. These links describe applications rather than imply a shared construction.


GOST 6533-78 — 1900 mm
For the catalogue elliptical profile of diameter 1900 mm, dish depth h2 = 475 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 1900 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 1900 mm
When ordering 1900 mm, specify a single item or set. Batch marking and acceptance rules can be agreed in advance.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- component quantity and completeness requirements;
- marking by project positions or drawings;
- drawing or technical specification for a project-specific configuration.

Quality inspection of heads 1900 mm
The main component parameters are checked before delivery. For a batch of D = 1900 mm, inspection covers compliance of each item with the drawing and geometry variation across the batch.
- compliance of diameter D = 1900 mm;
- elliptical dish depth h2 = 475 mm;
- metal thickness;
- ovality and knuckle geometry;
- surface and edge quality;
- compliance with GOST, technical specifications or the drawing.
