Why Pipe Stress Analysis Matters

Incomplete inputs = expensive rework

Missing temperatures, valve states, relief scenarios, elevation changes, or soil data drive redesigns late in the project.

Code misapplication

Confusing sustained vs. expansion stresses and odd code combinations can make “green” results non-compliant.

Transition blind spots

Buried-to-above-ground interfaces, pig launcher tie-ins, and nozzle loads are frequent failure points.

Vibration & fatigue are often underplayed

Reciprocating compressors, FIV/ Acoustic vibration, and thermal cycles can crack systems over time.

Tool & time pressure

Workarounds in non-piping FEA, license limits, and tight milestones invite shortcuts that risk safety and approvals.

Our Pipe Stress Analysis Capabilities

Thermal Expansion & Flexibility Analysis
Sustained (W+P), expansion (T), occasional (wind/seismic), and user-defined transients. Clear case matrices, allowables, and pass/fail summaries per code.
Combined Load Case Evaluation
Model operating/transient temperature ranges, expansion loops, guided/limit stops, expansion joints, and anchor strategies to prevent overstress at fittings, nozzles, and supports.
Support Design & Optimization
Spring hangers, constants, guides, axial/limit stops, struts, snubbers. We minimize reactions, deflection, and nozzle loads while preserving thermal freedom.
Vibration, Pulsation & Fatigue
Screen for FIV/Acoustic issues; assess compressor-induced vibration; estimate fatigue life for thermal cycles; propose tuned mitigations and bracing.
Underground Piping Stress Analysis
Soil–pipe interaction, settlement, heave, fixity at transitions, restrained vs. unrestrained segments, insulation/corrosion allowance impacts, and seismic wave effects.
Tubing Stress Analysis
Small-bore lines (instrument air, lube oil, seal systems): clamp spacing, vibration screening, bracket design, and connection load limits.
SolidWorks Pipe Stress Analysis (Bridged)
We bridge SolidWorks routing with stress evaluation by exporting routes, applying the correct SIFs, supports, and code checks in CAESAR II/ANSYS, and then returning the changes to CAD.

Industries We Serve

From greenfield EPCs to brownfield revamps, we deliver pipe stress analysis across regulated industries worldwide. Our teams understand each sector’s operating envelopes, codes, and reviewer expectations, so designs pass review, run safely, and stay maintainable.

Oil & Gas

Upstream flowlines, midstream transmission, and downstream units with hot hydrocarbon lines, flare/relief headers, compressor tie-ins, and tank-farm buried headers. We manage high temperatures and pressures, two-phase transients, and buried-to-above-ground transitions with clear nozzle-load checks and code-compliant margins.

Petrochemicals

Crackers, reformers, exchangers, and column circuits with large steam mains and expansion loops. We balance flexibility vs. support density, control thermal growth at towers/exchangers, and document sustained/expansion allowables for swift approvals.

Chemicals

Corrosive/abrasive services, batch cycles, and heat-traced lines. We model SIFs, corrosion allowance impacts, and occasional loads to prevent overstress and excessive deflection on long pipe racks and platforms.

Manufacturing

Utilities and process piping on long racks with settlement. We tune guides/stops/springs to limit rack reactions and rotating-equipment nozzle loads without over-constraining thermal movement.

Power

High-energy piping (HEP) in boilers/HRSGs and feedwater systems governed by ASME B31.1. We mitigate hot-stop settings, hanger selections, and start-up/shutdown transients to keep supports stable and anchors within limits.

Renewable Energy

Solar-thermal, biomass, and hydrogen/process utilities are exposed to wide thermal swings and pipe movement. We design expansion accommodation and vibration control, including low-temperature cryo transfer where applicable.

Water & Wastewater Treatment

Large-diameter buried networks, surge/water-hammer scenarios, soil-pipe interaction, and settlement/heave. Transition fixity and restraint strategies are documented to protect structures and equipment connections.

Refineries

Heat-affected, cyclic services with complex tie-ins and unit revamps. We reduce anchor/nozzle loads through support optimization and targeted route adjustments, prioritizing constructability and uptime.

Fertilizers

Ammonia/urea/utility lines with low-temperature service, CA/liner considerations, and occasional loads. We verify the restraint philosophy at cold boxes and ensure that transitions meet vendor allowances.

Pharmaceuticals

Hygienic pharmaceutical loops (CIP/SIP) and tubing systems, where small-bore vibrations can trigger failures. We set clamp spacing and bracket stiffness, screen for FIV/acoustic risks, and protect skids/equipment nozzles.

Emerging & Cross-Industry Expertise

Our engineering excellence goes beyond traditional sectors. From Finite Element Analysis (FEA) and Fitness for Service (FFS) to RCA, CFD, Pipe Stress, and Structural Design, we deliver solutions that transcend industry boundaries. Our multidisciplinary team applies the same rigor, safety, and innovation trusted by global leaders.
