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 1200 mm
Forming parameters for 1200 mm are coordinated with thickness and vessel application. For pressure equipment, provide design conditions in advance so requirements are not based on nominal diameter alone.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 1200 mm;
- elliptical dish depth h2 = 300 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 1200 mm
Applications for 1200 mm include LPG tanks and air receivers, with their own vessel design requirements.
- LPG storage tanks
- Vertical air receivers
- other vessels where D = 1200 mm is specified in the design documentation.
The application link describes a possible equipment class. Suitability of D = 1200 mm is confirmed only by the tank or receiver documentation.
GOST 6533-78 — 1200 mm
For the catalogue elliptical profile of diameter 1200 mm, dish depth h2 = 300 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 1200 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 1200 mm
For 1200 mm, state operating parameters in the enquiry to confirm the material and thickness.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- design or operating pressure and temperature;
- medium and pressure vessel requirements;
- drawing or technical specification for a project-specific configuration.
