Assess Piping System Stress & Loads

SIMFLEX-III, a cloud-based software, evaluates and analyzes dynamic and static pipe stress caused by structural, pressure, temperature, or environmental conditions. SIMFLEX-III checks sustained, occasional, and displacement stresses, at each piping inspection point, comply with all ASME B31 code stress requirements.

Experience SIMFLEX-III for yourself.


Visualize and explore calculation results using the software’s 2D and 3D visualization capabilities. SIMFLEX-III uses the solid code developed by Peng but is updated and improved for the next generation.

  • Check geometry using the 3D view of input piping systems
  • Output detailed text results for clear and easy review
  • View layout drawing dimensions, including key flange face location, bend tangent intersection, and piping vertical elevations

SIMFLEX-III Key Features

SIMFLEX-III performs several piping stress analyses to help you achieve maximum accuracy and productivity, using the following features:

  • Piping input keywords use industry standard terms
  • Run one of the available analysis: code compliance, spring design, rotating equipment load compliance, anchor & support load combination, limit stops
  • Code compliance to B31.1, B31.3, B31.4, and B31.8
  • View all input data on one screen for faster and more efficient data entry
  • Integrated analysis for load categories and operating conditions
  • Automatically combine all stresses into different categories to simplify code requirement comparisons
  • Output report includes all piping system data
  • Friction with unlimited supports and multiple load cases
  • Underground piping analysis with soil modeling and friction
  • Automated Bijlaard Analysis for pressure vessel nozzles
  • Natural frequencies and dynamic analysis including response spectra analysis for earthquake loading, time history analysis for arbitrary time dependent loads, and harmonic analysis
  • 3D graphics of input model and display of analysis results

SIMFLEX-III is available on the eec platform as an individual module or can be combined with other cloud tools for expanded analysis capabilities.
