Services
Piping Stress Analysis
Our core service evaluates piping systems under thermal and mechanical loads to prevent failures. We use ASME B31.1/B31.3 standards and proprietary software to analyze stress distribution, thermal expansion, and support requirements. Clients benefit from reduced maintenance costs and extended system lifespan through our precise calculations.
Failure Analysis
We investigate piping system failures caused by poor design, changed operating conditions, or code limitations. Our engineers identify root causes through field inspections and computational analysis. Clients receive actionable recommendations to prevent recurrence and improve system reliability under non-equilibrium conditions.
Finite Element Analysis
We create 2D/3D models to assess mechanical stresses in components like nozzles and flanges. This technique helps predict failure points under extreme loads and temperature gradients. Clients gain detailed insights into stress distribution patterns that traditional methods cannot capture.
CFD/Fluid Flow Analysis
Our computational fluid dynamics analysis examines complex flow behaviors in industrial systems. We model multiphase flows, heat transfer, and transient events to optimize equipment performance. Clients use these insights to improve system efficiency and prevent flow-induced mechanical failures.
Vibration Analysis
We diagnose vibration-related issues in piping and rotating equipment using advanced modeling techniques. Our analysis identifies resonance risks and fatigue damage potential. Clients implement our mitigation strategies to protect equipment and maintain operational continuity.
