Horizontal vessel Ø2 m × 6 m

1. What is being manufactured

Product
Horizontal pressure vessel
Volume with heads
≈ 21.1 m³
Only the volume is known — find Ø and length
Size the vessel by volume

Diameters follow the preferred GOST 9617-76 series up to Ø4.5 m (the GOST 6533 upper limit for heads). Volume is counted with both heads and their straight flanges, and the shell length is rounded up to 10 mm — so a variant is never smaller than the volume asked for.

With the selected formats the head comes out welded from pieces: a one-piece blank Ø2.44 m does not fit any sheet. That means extra welds and their inspection. A one-piece head needs a sheet of at least 2.44 × 2.44 m — add such a format to compare the cost.

4. Search depth

possible nesting variants: 320

Candidates are ordered by their preliminary estimate, so the cheapest guesses are solved first and the plainly expensive tail is cut off. More variants means a longer run and a better chance of finding something cheaper.

Vessel parts

The shell layout is preliminary: the final one is picked by the full order summary — metal, cutting, joints and vessel welds.

Role: Shell panel
Formula: circumference = π × diameter; axial length is split into stock-fitting courses
Sheet format: 2 × 12 m
Quantity 4: the course geometry follows from the circumference and the axial length; format 2 × 12 m was picked by the panel layout service.

Role: End heads
Quantity 2: two ends; geometry — blank circle Ø2.44 m (nominal Ø2 m, elliptical, blank diameter factor 1.175 (from geometry), straight flange 21 mm, trim allowance). Blank sheet 8 mm — as specified: the thinning allowance for pressing is already part of the drawing thickness. Available formats: 1.5 × 12 m, 1.5 × 6 m, 2 × 12 m, 2 × 6 m.

Mass = area × thickness × density of the part grade (by default the vessel material, 7850 kg/m³). Parts with their own grade or thickness are nested as a separate sheet group.
