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 3400 mm
Preparation for 3400 mm starts with technical documentation and logistics review. After forming, particular checks cover ovality and preservation of the profile during storage, loading and transport.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 3400 mm;
- elliptical dish depth h2 = 850 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 3400 mm
Applications for the upper size include LPG and fire water tanks, whose large structures have project-specific parameters.
- LPG storage tanks
- Fire water tanks
- other vessels where D = 3400 mm is specified in the design documentation.
D = 3400 mm is not a universal size for these tanks. It is used where specified by the particular equipment documentation.
GOST 6533-78 — 3400 mm
For the catalogue elliptical profile of diameter 3400 mm, dish depth h2 = 850 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 3400 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 3400 mm
For 3400 mm, include complete initial data. A large component should enter production only after the technical requirements are fully agreed.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- complete drawing with inspection dimensions, tolerances and edge requirements;
- delivery route, unloading conditions and assembly site restrictions;
- drawing or technical specification for a project-specific configuration.
