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
Common questions
Frequently asked questions
Do you work to B31.3 or B31.1?
Determined by service and facility type; B31.3 for process piping, B31.1 for power piping.
Do you check nozzle loads against connected equipment limits?
Yes, checked against the published allowables for the specific vessel, pump, or exchanger involved.
What is your typical spool drawing turnaround?
Structured around the fabricator's shop schedule rather than a fixed queue, confirmed per project.
