SIMFLEX-IV SOFTWARE

Static & Dynamic Piping Stress Analysis

Piping systems are designed to withstand a variety of external and internal stresses; however, any variation in mechanical or thermal loading, fluid flow, or weight may cause failure. With SIMFLEX-IV, you can proactively evaluate dynamic and static stresses to maintain integrity and code compliance across your entire piping system.

SIMFLEX-IV is a cloud-based piping stress analysis software that will help you prevent potential failures by improving the structural integrity of piping systems and supporting structures. The intuitive once-through workflow calculates code compliance analysis, spring hanger design, rotating equipment load compliance reports, anchor and support load combination tables, and nozzle stresses, with or without friction, all in one run.

When to use SIMFLEX-IV

SIMFLEX-IV is a fast and easy way to integrate advanced static and dynamic piping stress analysis into your daily workflow. Assess sustained, occasional, and displacement stresses at every data point throughout the piping system.

  • Apply piping loads to structural integrity and system operability components, including rotating equipment, flanges, tank connections, etc. 
  • Automatic selection of spring hangers 
  • Prepare maximum anchor and restraint load tables depending on different combined operating conditions. 
 

Modern Visualization

Visualize and explore calculation results using the advanced 2D and 3D visualization capabilities.

  • View all input data on one screen for faster and more efficient data entry
  • Check geometry using the 3D view of input piping systems
  • Output detailed text results for clear and easy review
  • View deformations and stress contours over the entire piping system, for all load cases analyzed

Integrated B31.J Analysis Capabilities

ASME B31.J provides standardized flexibility and stress intensification factors for all piping components and  branch connections. 

  • Fully integrated into SIMFLEX-IV for faster and easier analysis. 
  • Automatically detect an unlimited number of SIF locations and flexibility factors
  • Only a single keyword is needed, to analyze any piping system to ASME B31.J
