Technical overview

Static Equipment &
Pressure Vessel Engineering

Static equipment failures — pressure vessel burst, heat exchanger tube rupture, storage tank collapse — are among the highest-consequence events in the process industries. Sound mechanical engineering at the design stage, combined with correct material selection, NDE specification, and code-compliant fabrication oversight, is the primary defence. Arborion Global delivers complete static equipment engineering packages to ASME, API, TEMA, and PED standards, from wall-thickness calculation through witnessed factory inspection and code certification.

Engineering process

Static Equipment & Pressure Vessel Engineering workflow

Mechanical Design Basis

Establish MAWP, design temperature, fluid service classification, applicable code, and design life.

Code Calculations

Apply ASME Sec VIII Div 1/2, API, or PED equations for wall thickness, nozzle, head, and support design.

Material Selection

Review corrosion service conditions, HIC/SSC susceptibility, temperature limits, and material certification.

Structural & Fabrication Design

Design nozzle reinforcement, lifting lugs, saddles/skirts; specify NDE method, heat treatment, and inspection plan.

Vendor Document Review

Evaluate vendor fabrication drawings, material certificates, and welding procedure qualifications against spec.

Inspection Witnessing & Certification

Witness hydrostatic/NDE tests, verify code data report, and issue stamped certification or PED declaration.
