Technical overview

Equipment Sizing
& Specification

Equipment sizing and specification translates process simulation outputs into procurement-ready engineering documents. Under-specified equipment arrives undersized or over-designed; poorly written datasheets generate expensive vendor queries and commissioning rework. Arborion Global produces process datasheets and procurement specifications to API, ASME, and TEMA standards for static equipment, heat exchangers, pumps, compressors, and packaged units — complete to the point of ITB issue.

Engineering process

Equipment Sizing & Specification workflow

Process Duty Definition

Extract equipment duty from simulation output; define design conditions, flow compositions, and pressure/temperature envelope.

Sizing & Type Selection

Apply API, ASME, and TEMA sizing methods; select equipment type, configuration, and capacity margins.

Mechanical Design Coordination

Coordinate nozzle loads, support type, material grade, and corrosion allowance with mechanical discipline.

Datasheet Authoring

Prepare process datasheets to API/ASME/TEMA data-sheet format, ready for procurement and vendor submission.

Procurement Specification

Compile ITB technical specification, vendor pre-qualification criteria, and commercial evaluation matrix.

Vendor Review & FAT Support

Review vendor engineering documents, attend factory acceptance tests, and issue punch-list sign-off.
