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 1400 mm
During forming of 1400 mm, geometry is checked across the diameter for a uniform crown-to-knuckle transition, supporting subsequent automated or fixture-based shell assembly.
Checks during manufacturing include:
- initial blank thickness and condition;
- Diameter D = 1400 mm;
- elliptical dish depth h2 = 350 mm;
- knuckle geometry and uniformity;
- component ovality;
- surface and edge condition.
Applications of the elliptical head 1400 mm
Applications for 1400 mm include fire water tanks and gas-liquid separators, illustrating different industrial uses.
- Fire water tanks
- Gas-liquid centrifugal separators
- other vessels where D = 1400 mm is specified in the design documentation.
Application pages do not replace calculations. Fire water tank and separator thicknesses and materials follow different design data.
GOST 6533-78 — 1400 mm
For the catalogue elliptical profile of diameter 1400 mm, dish depth h2 = 350 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.
Germes-Ural manufactures heads 1400 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 1400 mm
For 1400 mm, confirm geometry tolerances and the subsequent shell assembly method.
- thickness S and material grade;
- required straight flange height h1;
- equipment application, medium, pressure and temperature;
- edge preparation and welded joint requirements;
- ovality requirements and allowable design deviations;
- subsequent shell assembly and welding method;
- drawing or technical specification for a project-specific configuration.

Frequently asked questions about the head 1400 mm
What dish depth and flange height are specified for elliptical head 1400 mm?
For diameter 1400 mm, the typical elliptical dish depth h2 is 350 mm, equivalent to 0,25D.
Can the head 1400 mm be used in fire water tanks?
Elliptical heads are used in this equipment class, but the actual diameter, thickness, material and geometry must match the specific vessel design.
What information is needed for a quotation?
For 1400 mm, confirm geometry tolerances and shell assembly method. Include D, thickness, material, h1, quantity, application and any drawing or specification.
Which material grades are available for elliptical head 1400 mm?
Yes, these materials are in the production range. The exact grade and thickness are confirmed after reviewing medium, temperature, pressure and design requirements.
Can elliptical head 1400 mm be manufactured to a drawing?
Yes. Manufacturing can follow GOST, technical specifications and individual customer engineering documentation.
Where can elliptical head 1400 mm be delivered?
Heads 1400 mm need stable support during transport so securing loads are not concentrated on sections of the knuckle.
