Stress Analysis & Flexibility

Stress Analysis & Flexibility services in Vancouver, Burnaby, Surrey, and throughout the Lower Mainland, BC. Professional piping & plant layout solutions.

OVERVIEW

Stress analysis and flexibility services throughout Vancouver, Burnaby, Surrey, and the Lower Mainland, BC. Proper stress analysis supports piping systems in safely accommodating thermal expansion, pressure loads, and external forces. Our stress analysis services verify that piping designs meet code requirements while supporting system integrity throughout the design life.

We perform comprehensive flexibility reviews that optimize support locations and minimize material costs. Our analysis considers operating conditions, startup scenarios, and emergency shutdown cases to support reliable system performance under all anticipated conditions.

  • Thermal stress analysis and flexibility calculations
  • Code compliance verification (ASME B31.3, B31.1, etc.)
  • Support location optimization and design
  • Expansion loop and expansion joint sizing
  • Nozzle load verification for connected equipment
  • Vibration analysis and mitigation strategies
USE CASES & APPLICATIONS

Stress analysis and flexibility services are essential for piping systems in industrial facilities throughout Vancouver, Burnaby, Surrey, and the Lower Mainland, BC. We analyze high-temperature steam systems, process piping subject to thermal cycling, and systems with significant pressure variations. Our services are particularly important for critical piping systems where failure could result in safety hazards or production losses.

We support projects across oil & gas, power generation, pulp & paper, and chemical processing industries. Our stress analysis supports piping systems in safely accommodating thermal expansion during startup and shutdown cycles, pressure transients during operation, and external loads from equipment and structures. BC's industrial facilities often operate under demanding conditions—high temperatures, pressure cycling, and seismic loading. Our stress analysis supports reliable system performance under these conditions while meeting code requirements.

PROCESS & WORKFLOW

We begin by understanding operating conditions including design temperatures, pressures, and thermal cycles. We model piping systems accounting for thermal expansion, pressure loads, weight, and external forces. Our analysis verifies that stress levels remain within code-allowable limits under all operating conditions.

We optimize support locations to minimize material costs while supporting adequate flexibility. We design expansion loops and specify expansion joints where needed to accommodate thermal movement. We verify that nozzle loads on connected equipment remain within manufacturer limits, supporting equipment protection from damage due to piping loads.

Our stress analysis process goes beyond code compliance—we optimize designs for cost and constructability. By analyzing multiple support configurations, we identify solutions that reduce material costs while maintaining safety margins. We work closely with structural engineers to support practical support designs that can be installed efficiently by local contractors.

INDUSTRY STANDARDS & COMPLIANCE

Our stress analysis complies with ASME B31.3 for process piping, ASME B31.1 for power piping, NBCC seismic requirements, and other applicable codes. All stress levels are verified to meet code requirements including sustained stress, expansion stress, and occasional stress limits. Our analysis accounts for fatigue considerations where thermal cycling is significant. BC's seismic requirements add complexity to stress analysis, particularly for tall structures and elevated piping. Our analysis incorporates seismic loads per NBCC requirements, supporting system functionality after seismic events.

FREQUENTLY ASKED QUESTIONS

FAQs

When is stress analysis required for piping systems?
Stress analysis is typically required for high-temperature systems, systems with significant thermal expansion, critical process piping, and systems where nozzle loads on equipment must be verified. Code requirements vary based on pipe size, temperature, and service conditions. We can help determine when stress analysis is needed for your specific application. Early analysis can identify issues before detailed design, saving time and money.
