Elliptical head 1000 mm — profile diagram

Cylindrical pressure vesselsFlare separators (FS)

The elliptical head 1000 mm is a metric catalogue size for process vessels and tanks. It can follow the catalogue profile or an agreed drawing with project-specific flange and edge requirements.

At diameter 1000 mm, typical h2 = 250 mm. Confirm the mating dimension, shell thickness and any additional edge machining before manufacturing.

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 1000 mm

Cold forming and flanging of dished ends

Inspection of D = 1000 mm focuses on mating diameter, ovality and straight flange, particularly when the head is delivered to another facility for assembly with a prepared shell.

Checks during manufacturing include:

  • initial blank thickness and condition;
  • Diameter D = 1000 mm;
  • elliptical dish depth h2 = 250 mm;
  • knuckle geometry and uniformity;
  • component ovality;
  • surface and edge condition.

Applications of the elliptical head 1000 mm

Diameter 1000 mm is used in several equipment classes. Related applications include air receivers and tanks; suitability remains project-specific.

Pressure vessels and tanks have different material and inspection requirements. State the equipment application before requesting a price.

Vessel equipment applications
Dished-end profile and manufacturing requirements

GOST 6533-78 — 1000 mm

For the catalogue elliptical profile of diameter 1000 mm, dish depth h2 = 250 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 1000 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 1000 mm

For D = 1000 mm, confirm both sheet thickness and the mating diameter against the actual customer shell.

  • thickness S and material grade;
  • required straight flange height h1;
  • equipment application, medium, pressure and temperature;
  • edge preparation and welded joint requirements;
  • diameter specified in the drawing: external, internal or mating;
  • edge preparation for the specific welded joint;
  • drawing or technical specification for a project-specific configuration.

Geometry and quality inspection of dished ends

Quality inspection of heads 1000 mm

The main component parameters are checked before delivery. In addition to the overall profile, the straight flange is checked for compliance with the agreed shell mating geometry.

  • compliance of diameter D = 1000 mm;
  • elliptical dish depth h2 = 250 mm;
  • metal thickness;
  • ovality and knuckle geometry;
  • surface and edge quality;
  • compliance with GOST, technical specifications or the drawing.
