Heavy Process Equipment Manufacturing
ATTOMO manufactures heavy process equipment, including process columns, pressure vessels, reactors, tanks and fabricated assemblies. Supply can follow customer-approved drawings or include engineering within the equipment package, with materials, inspection and delivery responsibilities clearly defined.
Process and equipment approach
Critical-service equipment needs an agreed code, design conditions, material specification, fabrication controls and inspection plan. Describing equipment as critical or high pressure does not establish its approved operating envelope or certification.
Applications and product requirements
Vessels, reactors, mixers and fabricated assemblies may face demanding pressure, temperature, corrosion or mechanical duties. The equipment specification connects these service conditions with the required materials, design calculations, fabrication controls and inspection plan.
Equipment and operating approach
Equipment selection connects the process duty with mechanical design, load cases, agitation or rotating interfaces where applicable, supports and maintainability. Existing equipment replacement also requires tie-in measurements and a review of the original failure or limitation. Fabrication should follow approved drawings and a defined inspection plan.

The quotation defines the included equipment, services and battery limits.
- Specified vessels and process assemblies
- Agitator and skid interfaces as contracted
- Fabrication and inspection planning
- Testing and handover documentation
Materials and configuration
Specify material grade, applicable design code, design pressure and temperature, corrosion allowance, cyclic loads and required examination. Third-party inspection, certification or code stamping must be explicitly agreed and supported by current credentials. Design to a code and authorisation to apply a certification mark are different claims.
Utilities and operation
Utilities depend on the equipment: a heated vessel, vacuum dryer and agitated reactor have different demands. State heating or cooling duties, motor and drive requirements, seal arrangements, connections and the boundary for controls. Pressure relief, protective devices and site integration need assigned design responsibilities.

| Topic | Information to provide |
|---|---|
| Equipment and quantity | Identify each column, pressure vessel, reactor or tank, with working volume/dimensions and number of units. |
| Duty and construction | Contents, design pressure/temperature, vacuum, material, corrosion allowance, nozzle schedule and supports. |
| Included assemblies | Identify internals, trays, agitation, drives, seals, jackets/coils, insulation and instruments rather than assuming inclusion. |
| Design and acceptance | Assign design responsibility and specify drawings, applicable code, inspection, testing and document handover. |
| Transport and site | Destination, lifting/transport constraints, site interfaces and any required erection or commissioning support. |
Frequently asked questions
Can a pressure or temperature rating be assumed from a similar vessel?
No. Material, geometry, loads, fabrication and the applicable code determine the design. Provide the full operating and design conditions.
Are motors, gearboxes and seals included with agitated equipment?
Only as stated in the quotation. Define fluid properties, viscosity range, mixing duty, drive arrangement and the supply boundary.
Does code-based design mean the equipment is certified?
Not automatically. Required certification, inspection and stamping must be expressly included and supported by the relevant authorisations.

Pressure vessels, reactors and tanks
ATTOMO reviews pressure vessels, reactors and tanks as distinct equipment duties. A pressure-vessel enquiry needs the pressure and temperature basis, volume, material, design-code requirement and nozzle/interface information. A reactor additionally requires the mixing, heating/cooling and process-responsibility basis. A tank enquiry must identify storage duty, contents, operating conditions and installation requirements.
Supply can follow customer drawings or an agreed engineering scope. Internal components, agitation, supports, insulation, instruments and connected piping are itemised rather than assumed to be included. Material suitability and construction are selected for the actual process medium and mechanical duty.
The quotation identifies the applicable inspection and test plan, material records, fabrication documentation and any third-party involvement. A requested code or inspection requirement is reviewed before acceptance; no code stamp or unrestricted pressure rating is implied.
