NozzlePRO v12.1

Thermal Gradient Shoe 1


NozzlePRO is a unique and easy-to-use FEA tool for vessel and piping engineers.  It is specifically designed to analyze individual nozzles (straight, hillside, pad-reinforced), saddles, lugs and pipe shoes. Reinforcing pads for lugs and wear plates for shoes and saddles can be integral and non-integral.  You can include beam elements to pipe up to the nozzle in order to include the correct attached pipe stiffness and thus applying the correct loads in your analysis.

What is included with NozzlePRO?

Although NozzlePRO is very effective as a stand-alone product, several advanced modules are bundled with the program to enhance analysis capabilities.


These modules were designed to add increased ease-of-use & design for the most common analysis needs. All of these modules use the FEA engine from FEPipe to perform the high-level calculations and reporting. All of the following modules are included with NozzlePRO v12.1 as specialized templates.

  • MATpRO
  • Fitness for Service


These modules were also designed to add increased ease-of-use & design for the most common analysis needs. Some of the STANDARD templates were converted to more simplified analysis tools. These modules are included with an active NozzlePRO v12.1 service plan.

• FE107
• FETee
