Flanged conical head 1700 mm. The cone connects the large diameter D to the small diameter d; the formed edge provides the transition to the cylindrical section.
Germes-Ural manufactures flanged conical heads of diameter 1700 mm to the agreed drawing. Profile and thickness are selected for the equipment; applicable GOST requirements are considered in the project and order.

The table retains the company’s published dimensions. The combination of size, material and loads is agreed against the drawing; the thickness range does not establish an allowable operating pressure.
Manufacturing heads 1700 mm
For the large diameter 1700 mm, the catalogue specifies d ≥ 600 mm, α 80–150° and H ≤ 1300 mm. These limits are checked as one complete profile, including knuckle radius r = 50–200 mm.
- Mating diameter and tolerances
- Agreed profile and smooth transitions
- Finished component thickness
- Straight flange and weld edge preparation
- Compliance of the material with the specification
Applications of heads 1700 mm
Specify the operating requirements for the equipment: Heads for flare separators (FS), Heads for horizontal air receivers. The size and profile are selected according to the equipment design.
Cone angle α, small-end diameter d and overall height H are geometrically linked. Catalogue values should not be selected independently: the complete profile and its suitability are checked by the equipment design.
Profile 1700 mm and requirements GOST
GOST 34347-2017 sets general technical requirements for welded steel vessels. Calculations for cylindrical and conical components, dished and flat heads use the applicable provisions of GOST 34233.2-2017 and the project documentation.
The catalogue shows the company’s production range. It does not extend the scope of the standards or replace allowable pressure calculations. The profile, radii, heights and finished thickness are agreed in the technical specification and drawing.
Feasibility of a welded blank
For a multi-part blank 1700 mm, the weld layout follows the project. Agree position restrictions and inspection scope in advance. Diameter alone does not establish the need for or feasibility of welded blanks.
For flanged conical heads 1700 mm, include this requirement in the technical specification together with the profile dimensions: α = 80–150°, d ≥ 600 mm.

Frequently asked questions
Can welds be prohibited in a specified zone of 1700 mm?
Yes. Submit the restrictions in the order documentation. Manufacturing feasibility is reviewed before work starts.
How is the allowable operating pressure determined?
No. The catalogue interval describes a production range; suitability of an angle depends on the construction, loads and calculations. Include D, d, α, H and a drawing of the transitions in the enquiry.
What thickness is available for flanged conical head 1700 mm?
The published table lists thicknesses of 4–22 mm. Thickness is selected by calculation for the medium and loads. Material, allowances and the condition after forming are recorded in the documentation.
What information is needed for a quotation?
Provide the drawing, material grade, thickness, quantity, operating conditions, edge preparation, openings and inspection requirements. Include the delivery destination and unloading conditions.
What is the lead time for flanged conical head 1700 mm?
The lead time is confirmed after the specification is agreed, taking into account blank availability, batch size and processing operations.
Delivery of heads 1700 mm
Packaging and transport are selected for the actual height, weight and batch quantity. For the large diameter 1700 mm, the catalogue specifies d ≥ 600 mm, α = 80–150° and H ≤ 1300 mm. These limits are confirmed as one profile, including knuckle radius r = 50–200 mm.
Prepared edges and surfaces are protected during transport. Include unloading conditions and any special packaging requirements in the order.
