Engineering Support for Piping Systems Fabricators
Piping design sits at the intersection of code compliance, thermal behaviour, and support engineering. Getting any one of the three wrong shows up as a fit-up problem, a flange leak, or a failed inspection. We support piping fabricators with design, stress analysis, and drawing scope across oil & gas, process, fertiliser, utility, renewable, and power sector piping.
Codes & Regional Compliance
- United States / global baseline: ASME B31.3 for process piping; ASME B31.1 for power piping, selected based on the service and facility type.
- Canada:B31.3/B31.1 design basis applied alongside provincial pressure-piping registration requirements where applicable.
- Europe: PED-aligned documentation for piping assemblies falling under the directive's scope, alongside EN piping standards where specified in place of ASME.
- Australia: AS 4041 for process piping design where specified as the governing standard.
- Flange & fitting standards: design checked against the relevant regional flange/fitting standard (ASME B16.5/B16.47 or EN equivalents) to avoid gasket seating and bolt-load mismatches at the interface with vendor equipment.
Design Checks Unique to Piping Systems
- Thermal expansion and flexibility analysis, confirming the routing absorbs thermal growth without overloading supports or equipment nozzles.
- Support spacing and type selection, accounting for operating weight, insulation, and fluid contents, not just pipe self-weight.
- Flange leak and gasket seating checks at critical joints, particularly where dissimilar flange ratings or standards meet.
- Nozzle loading at equipment connections, checked against the allowable loads published for the connected vessel, pump, or exchanger.
Typical Deliverable Set
- Piping isometrics
- Stress analysis report covering thermal, weight, and occasional load cases
- Support drawings and schedule
- Fabrication spool drawings
- BOM covering pipe, fittings, flanges, and supports
Common Mistakes / Revision Triggers
- Support spacing set without accounting for insulation or operating fluid weight
- Thermal growth not checked against the connected equipment's published nozzle load allowables
- Flange standard mismatch discovered only at the bolt-up stage
