Finite Element Analysis Engineers
FEA stress analysis for engineering solutions
About Finite Element Analysis
Finite Element Analysis (FEA) allows engineers to evaluate stresses, deformations, and load paths that cannot be captured with traditional beam-element pipe stress software. Local shell stresses, nozzle interactions, saddle behavior, clamp deformation, and thermal gradients all require a level of detail beyond what ASME B31 codes or simplified methods can provide.
JSC Engineers performs advanced FEA for piping, pressure vessels, and support components. We specialize in analyzing nozzle loads, large branch intersections, heavy clamp and cold-shoe assemblies, and attachments on thin-wall piping where D/t ratios exceed the limits of code rules. Our models follow ASME Section VIII-2, Part 5 methods for elastic–plastic, buckling, and fatigue assessment.
Industries We Serve
- Oil & Gas – nozzle loads, local shell stress, large-bore piping
- Chemical Processing – jackets, mixers, vessel attachments
- Wastewater/Water Treatment – thin-wall tanks, aeration piping
- Power Generation – high-temperature components, supports, clamps
- Mining – slurry piping, wear components, heavy support structures
- Pulp & Paper – vessel nozzles, rotating equipment connections
- Aerospace – high-performance piping and thermal systems
- Commercial & Industrial HVAC – large-bore duct nozzles and supports
FEA Driven by Code-Based Requirements
Our engineers apply FEA in accordance with ASME pressure vessel, piping, and structural requirements. Local stresses, buckling, plastic collapse, and fatigue evaluations follow the Part 5 procedures of ASME Section VIII, Division 2. For piping systems, FEA is used to refine or replace simplified methods such as WRC-107/297 when they fall outside their applicability.
- ASME Section VIII, Division 2 – Part 5 Elastic-Plastic, Buckling, Fatigue
- ASME B31.1 – Power Piping (local stress verification)
- ASME B31.3 – Process Piping (SIF & flexibility refinement)
- API Standards for vessel and tank evaluation
- Piping Saddles
- ASCE 7 & IBC for structural loading on attachments
Advanced FEA for Reliable, Real-World Piping Solutions
Our team uses NozzlePRO, FE/Pipe, and SolidWorks Simulation to evaluate stresses that occur in complex geometries where code equations and beam theory fall short. Situations such as large branch intersections (d/D > 0.50), high D/t ratios, saddle-supported vessels, clamp assemblies, and thermally loaded components often require detailed FEA to capture true behavior.
We perform elastic, elastic-plastic, buckling, and fatigue assessments for:
- Nozzle and branch-connection loads
- Accurate SIF and flexibility computations
- Thermal gradients through pipe wall thickness
- Heavy clamps, cold shoes, and special supports
- Local stresses under external pressure or vacuum
- Flange and bolting behavior under combined loading
By using detailed FEA instead of conservative or outdated code approximations, we help reduce unnecessary reinforcement, identify true overstress conditions, and ensure safe operation with optimized designs. Our results are clear, code-based, and ready for submittal to owners, structural engineers, and AHJs.
