We are dealing  with  stainless steel process vessel (CAPACITY RANGE FROM 500L TO 20KL) is a large, industrial container made from stainless steel, primarily used in manufacturing processes to mix, store, heat, or cool various substances, often in industries like pharmaceuticals, food & beverage, chemicals, and cosmetics, due to its excellent corrosion resistance and hygienic properties; these vessels can be custom-designed with features like agitators, heating/cooling jackets, and level sensors to suit specific process requirements. 

we are GRF Dynamic Engineering dealing with Stainless steel dimpel jacket pressure vessel with capacity range 1000L to 20kl 
1000l tofor SS dimple-jacket vertical pressure vessels from 1 KL (1,000 L) up to 20 KL (20,000 L) so you and your fabricator can quickly pick a suitable size and see typical dimensions, jacket area and rough material weight. These are approximate — final design must follow the chosen code (eg. ASME VIII Div 1 / local code) and exact design pressure/temperature.
Quick assumptions usedVertical cylindrical shell with integral/dished heads.L/D (straight length / diameter) chosen ≈ 1.5 (common compact layout).Shell thickness for weight estimate: 6 mm (typical for low–medium pressure).Jacket (dimple plate) thickness: 2 mm (dimple plate).Material: SS (density 8000 kg/m³).Heads area estimated by a practical factor (not a detailed head-by-head calc).
These numbers are for preliminary selection only.> Notes: “Rough material mass” above = shell + jacket plate only (heads + shell + jacket). No allowance for internal fittings, agitator, insulation, supports, nozzle reinforcement, manhole, piping, surface finish, or internal components.


Typical design choices / recommendations
Material: SS304 or SS316L depending on corrosion / product compatibility.
Design code: ASME VIII Div 1 (or local equivalent). Specify required
stamping/certification.Design pressure (shell): specify (e.g. 0.5, 1.0, 3.0, 6.0 bar g). Shell thickness will be code-calculated from that.Jacket pressure rating: commonly 3–6 bar for steam/service; for high-pressure steam specify accordingly.Jacket type: dimple plate (spot-welded) — good heat transfer vs. lower weight.
Insulation & cladding: usually PUF + SS304 cladding for hot service.Agitator: specify if mixing required (type, RPM, shaft penetration).Nozzles & typical sizes:Product inlet/outlet: DN50–DN150 depending flow.Jacket inlet/outlet: DN25–DN65 (depends on heat duty).Drain: DN25–DN50.Vent / safety / instrumentation connections per process needs.Manhole: DN400–DN600 typical for cleaning/CIP access (if required).Support: skirt, legs or saddles depending on height and piping.Surface finish: Ra requirements if for pharma/food.Heat transfer / steam sizing (brief)Jacket area shown gives conductor area available for heat transfer. Exact steam flow (kg/hr) depends on:
Required temperature rise (ΔT), product properties, required heating time, and overall heat-transfer coefficient.As an example, to estimate steam kg/hr you’ll need: mass of product × Cp × ΔT / latent heat of steam, adjusted for U × area efficiency. I can run a quick steam sizing for any chosen capacity & ΔT if you want — tell me desired start/end temperatures and heating time and I’ll calculate.
What I can do next (pick any, I’ll do it now)
1. Run detailed thickness calculations (ASME formula) and produce a GA sketch + weight & nozzle list for a specific capacity and design pressure/temperature.
2. Do steam/glycol heat duty & steam kg/hr sizing for a chosen capacity (give start temp, final temp, heating time).
3. Prepare a procurement spec/techno-commercial template you can send to fabricators (materials, tests, painting, docs).
