Artisan mechanical engineers are all registered professional engineers. We can design the most complex and challenging pressure vessels with custom features including:

Pressure Vessel Analysis

Finite Element Analysis

  • ASME Division 1 & 2
  • Specialty alloys
  • Shell buckling
  • Fatigue design
  • Strain gage and burst testing for proof of non-standard designs
  • Special loading conditions requiring non-standard calculations per ASME U-2
  • Dimpled, half-pipe, and baffled jackets using steam or liquid
  • High temperature design
  • Lethal categorized vessels
  • Special static and dynamic sealing principles
  • Thermal stress and strain
  • Large columns with severe wind and seismic specifications
  • Quick-actuating closures

Our engineers have the latest tools for solving the most challenging projects

Industry-standard software allows Artisan to maintain a completive edge by reducing engineering time and helping provide the most cost-effective solutions.

Difficult calculations requiring knowledge and experience with fatigue, external loading, thermal strain and non-linear material characteristics are reasons why customers seek Artisan for their solutions. Shown here is an FEA of a vessel connection too large to be readily checked using ASME code calculations. The FEA nozzle stress analysis shown was required per the ASME code Appendix 1-7 and U-2.


Sample Custom Pressure Vessels

100 sq. ft. Rototherms

100sf Rototherms

These 100 sq ft Rototherms were shipped to South Korea and met all local codes and standards. Similar designs have been checked for low cycle fatigue, thermal stress and special connection geometry outside the routine scope of the ASME pressure vessel code.

70 foot Separation Column, Under Construction

column construction

Artisan designed this 70 foot column for use in separating solvents. The design required integrating the customer’s piping flexibility models to external loading on the column’s connections. Shell section material weight was also minimized using external pressure reinforcing rings that doubled as insulation supports.

45-foot Separation Column

45' separation column

This 45 foot column was designed to limit heat lost through a separation process using clamp-on steam jackets. The temporary saddles shown were constructed and attached for testing, shipping, and installation.
