SIMFLEX-III

A NEW AND UPDATED WEB-BASED PROGRAM

SIMFLEX-III is accessed through a web browser and executed in a cloud computing environment.
SIMFLEX-III has new web-based three-dimensional graphics capabilities, including a new web-based viewer to review the output file and maintain the component-oriented input scheme that greatly simplifies the input process that reduces the chance of error.
SIMFLEX-III maintains the once-through process, allowing the code compliance analysis, spring design, rotating equipment load compliance report, anchor and support load combination table, limit-stop, and friction inclusion to be done with a single set-up of input data in a single computer run.

UNIQUE FEATURES

SIMFLEX-III is accessed through a web browser via a tablet, iPad, or PC, and executed in a cloud computing environment. Pipe stress analysis is a very involved and complicated task. It can be done practically only by use of computers. Software packages designed for Pipe Stress Analysis vary greatly on method and philosophy.
To ensure maximum accuracy and productivity, SIMPLEX-III has implemented the following unique features:

  • Layout drawing dimensions such as key flange face location, bend tangent intersection, and piping vertical elevation.
  • Familiar piping language as keywords for input data. This not only makes the input simple and straightforward, but also establishes a common protocol for all parties involved. A third party that reviews the report would understand what it is all about.
  • A very efficient input scheme such that the entire input data can be shown on one screen.
  • Integrated Analysis for all load categories and operating conditions. With this advanced arrangement, the program knows all the situations expected from all specified operations. Knowing these situations, the program will calculate the stress range correctly if there are opposing operating temperatures expected. The spring hangers designed can also accommodate all the expected operating displacements.
  • The ability to automatically combine all the stresses into different stress categories for comparison with code requirements. This is possible only with an Integrated Analysis because each category of stress involves more than one load case. A code stress compliance table or chart, therefore, can be created automatically.
  • A complete output report with everything in one place. Input data echo, system description, support force, pipe force and stress, pipe displacement, vessel local stress, flange operating stress, tank nozzle load evaluation table, spring hanger selection table, rotating equipment load compliance table, and code stress compliance table are all contained in one integral report.

 

STEP BY STEP GUIDANCE

Step 1 – The user creates a SIMFLEX-III input file using a special editor. The input file is submitted and checked for errors.

 

 

 

 

 

 

 

 

 

Step 2 – A three-dimensional graphic display of the input piping system is provided to check the geometry. Standard graphic manipulation such as zoom and rotate is provided. Node numbering may be displayed along with specific piping component types, including straight pipe, elbows, valves, equipment connections, spring hangers, etc. The SIMFLEX-III input file is submitted to the SIMFLEX-III Cloud Computing Environment, and then output and graphics files are returned to the user.

 

 

 

 

 

 

 

 

 

 

Step 3 – Using a viewer created to streamline browsing of the analysis results, the user may review the SIMFLEX-III output file. In addition, graphical display of output is provided including deformed shape and stress contours indicating the highest stressed areas.

 

 

 

 

 

 

FUTURE DEVELOPMENT

E2G strives to provide clients the best service by staying ahead of the technology curve. They chair many of the industry committees where needs are discussed, and codes and standards are set. E2G clients benefit from their deep industry knowledge, technical expertise, and practical solutions derived from years of experience working in facility environments. E2G’s engineering experts will ensure that SIMFLEX-III adheres to the latest industry guidance, while enhancements are made to increase functionality.

BUILT BY AN INDUSTRY PIONEER

Liang-Chuan Peng was a pioneer in piping technology, coauthoring one of the most thorough and technically advanced publications on the subject titled Pipe Stress Engineering. The book’s coauthor was Liang-Chuan’s son, Tsen-Loong Peng. The book was published by the American Society of Mechanical Engineers in 2009 and is available on the ASME website.

The original SIMFLEX Software program released in 1980 for Pipe Stress Analysis was authored under the leadership of Peng Engineering’s founder and recognized industry expert, the late Liang-Chuan Peng, and continues to be considered the definitive reference on pipe stress engineering.
