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 2600 mm
Batch production of 2600 mm requires stable process settings so every component remains within agreed parameters. Record inspection results consistently across the batch.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 2600 mm;
- elliptical dish depth h2 = 650 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 2600 mm
Related applications include BUON units and industrial separators.
- BUON oil dehydration units
- Industrial separators
- other vessels where D = 2600 mm is specified in the design documentation.
D = 2600 mm is not a universal standard for oil and gas vessels. It is used only where specified by the project documentation.
GOST 6533-78 — 2600 mm
For the catalogue elliptical profile of diameter 2600 mm, dish depth h2 = 650 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 2600 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 2600 mm
For several heads 2600 mm, specify interchangeability and batch marking requirements.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- interchangeability requirements within the batch;
- numbering and marking of each head;
- drawing or technical specification for a project-specific configuration.
