Finite Element Analysis for the Pressure Vessel and Piping Industry

FEPipe is a template-based software solution specifically designed for use in the pressure vessel and piping (PVP) industry. Based on the chosen template, FEPipe performs detailed simulations using Finite Element Analysis (FEA) to comply with the ASME B&PV Section VIII Division 2. What separates FEPipe from general purpose FEA software packages is its ability to rapidly construct PVP geometries and produce ASME code compliance reports.

 

The parametric approach used in FEPipe permits even novice pressure vessel engineers to construct accurate models using only dimensional input. FEPipe automatically creates the model geometry, finite element mesh, applied loads, and boundary conditions based on standard dimensions. Results are presented in terms of ASME code compliance reports instead of generalized stress tensors and stress intensities as general FEA tools tend to do.

Software Capabilities

A large number of common PVP geometries can be modeled using FEPipe templates:

  • Unreinforced and reinforced tees, lateral, and hillside nozzles or piping intersections
  • Saddle supported vessels and heat exchangers
  • Large diameter piping and ducting using shell elements
  • Piping systems using standard 6 degree of freedom (DOF) beam elements, new 18 DOF beam elements, or shell elements
  • Vessels with all geometric features including nozzles, support skirts, heads, structural clips, and stiffening rings.
  • Flanges with bolt loads, pressure, external loads, and thermal analysis
  • Tangential entry nozzles in cylindrical shells (rectangular, obround, and cylindrical nozzles)

 

FEPipe includes a load case processor that automatically accounts for load cases that contribute to failure in piping and pressure vessel components. Such as weight, thermal load, internal/external pressure, seismic loads and loads due to acceleration or fluid head.

 

Advanced analysis options include linear-elastic, plasticity, fitness-for-service, high temperature creep, buckling and harmonic convergence.

FEPipe is extensively validated

 

At the most basic level, the element formulations and related output have been compared against classical hand calculations. Additionally, FEPipe has been validated and benchmarked against other general FEA software tools. The benchmark problems have included a range of complexity from single element verification problems to complete PVP analysis cases. In addition, Paulin Research Group routinely conducts experimental work in the PRG Laboratory. FEA models are constructed for comparison against strain gauge measurements from experimental cases. This work extends to included burst tests, fatigue tests, cryogenic work, and heat transfer experiments. Further, PRG is active in the PVP research field and continually processes other available test data for validation of the model building and analysis approaches used in FEPipe.
