Static Equipment and Pressure Vessel Engineering

We deliver ASME compliant pressure vessel, heat exchanger and tank engineering from calculation through to code certification

Technical overview

Static Equipment and Pressure
Vessel Engineering

Static equipment failures such as a pressure vessel burst, a heat exchanger tube rupture or a storage tank collapse are among the highest consequence events in the process industries. The primary defence is sound mechanical engineering at the design stage, combined with correct material selection, clear non destructive examination specification and code compliant fabrication oversight. Our team delivers complete static equipment engineering packages to ASME, API, TEMA and PED standards, taking your equipment from wall thickness calculation through witnessed factory inspection to code certification.

Static Equipment and Pressure Vessel Engineering Overview
Engineering process

Static Equipment and 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.
