Using the CodeCalc interface with Paulin Research Group's NozzlePRO software, you can perform FEA while designing thick expansion joints from within CodeCalc. FEA lets you calculate more precise data for certain properties of expansion joints.

Complete the following steps to perform finite element analysis (FEA) on thick expansion joints in CodeCalc.

You must have installed NozzlePRO from Paulin Research Group to perform FEA on expansion joints in CodeCalc.

  1. Open CodeCalc .

  2. Click Add new ASME Tubesheet or Add a new TEMA Tubesheet in the Components panel.

  3. On the Tubesheet tab, specify a fixed Type of Tubesheet (such as (F/D) Fixed, gasketed both sides for ASME or (F) Fixed tubesheet exchanger, 2 stationary tubesheets for TEMA).

  4. Specify the Expansion Joint Type as Thick (Flanged-flued).

  5. On the Expansion Joint tab, set the Design Option to Analyze.

  6. Specify the Expansion Joint Calculation Method as FEA.

    The software enables several boxes applicable for finite element analysis and disables inputs that are unnecessary to the expansion joint calculations.

  7. Specify the Elastic Modulus, FEA Runtime Option, and Poisson's Ratio.

    The FEA Runtime Option selection determines what stress calculations the software uses and displays on the ASME TS Calc or TEMA TS Calc output reports. The ASME and TEMA tubesheet modules use TEMA 9th edition standard for thick expansion joint FEA calculations.

  8. Click Analyze. After the analysis completes, refer to the Expansion Joint Stress Summary (PRG) section on the output report.
