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 1500 mm

Cold forming and flanging of dished ends

For 1500 mm, plan production with shell readiness. Agreed dimensions allow transfer to assembly with a defined mating fit. Batch orders also require repeatability checks.

Checks during manufacturing include:

initial blank thickness and condition;
Diameter D = 1500 mm;
elliptical dish depth h2 = 375 mm;
knuckle geometry and uniformity;
component ovality;
surface and edge condition.

Applications of the elliptical head 1500 mm

Related applications include oil buffer degassers and air receivers, with different purposes and a shared need for the specified head profile.

BDN oil buffer degassers
Horizontal air receivers
other vessels where D = 1500 mm is specified in the design documentation.

BDN parameters always follow the vessel documentation. The link describes an elliptical head application rather than the standard size of a particular model.

GOST 6533-78 — 1500 mm

For the catalogue elliptical profile of diameter 1500 mm, dish depth h2 = 375 mm, or 0,25 of D. Straight flange height h1 depends on thickness and the agreed configuration.

Germes-Ural manufactures heads 1500 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.
