Engineering Capabilities

HOLLOWAY offers the following machine engineering services: Custom Vessel Design, Finite Element Analysis, and CAD or 3D Modeling

Custom Pressure Vessel & Maching Engineering Services

The Engineers and Designers in the HOLLOWAY AMERICA Engineering Department have decades of combined experience designing equipment for the Pharmaceutical, Biotech, Chemical, Food and Beverage industries. With thousands of projects of various scopes under their belts, they’ve gained the versatility to create optimal solutions for customers’ problems and applications. Our three full-time Mechanical Engineers and six Designers use a variety of Computer Aided Design Systems, which include:

  • AutoCAD Mechanical 2019 - 2D
  • Autodesk Inventor 2019 – 3D
  • Pro-E (PTC CREO) – 3D

Codes and Standards

HOLLOWAY Engineers design vessels and equipment in accordance with several codes and standards, which include:

  • ASME Section VIII, Division I
  • CE/PED for Europe
  • MOM – Singapore
  • CRN – Canada
  • API 620 and API 650
  • ASME B31.3 Process Piping
  • National Board “R” Repair Stamp
  • IBC, International Building Code
  • ASCE 7


HOLLOWAY Engineers use several types of software to verify equipment designs. ASME Code Calculations are performed in Compress to verify that stresses are within the limits specified in Section VIII, Division I.

Heat transfer calculation are performed using two In-House Programs which determine the required area of the heat transfer jackets to assure the heating and cooling requirements can be achieved. Pressure drop calculations are also performed on this software.

Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD)

Finite Element Analysis (FEA) is a computerized method for predicting results from a complex scenario. The scenario will determine how a piece of equipment – single part or assembly – will react to stress, temperature, fatigue and other physical effects. It’s a method to predict how the equipment will react to real-world loads.

Computational Fluid Dynamics (CFD) predicts fluid flows and heat transfer through a specified geometry. Examples of CFD problems can be specialized heat transfer jacket problems and visualizing agitator mixing action. 

Temperature, pressure and force results from Simulation CFD can be applied to Simulation Mechanical to determine stress and displacement results on components containing the fluid flow.

HOLLOWAY Engineers use the latest technology for FEA and CFD, which includes: 

  • Autodesk Inventor Professional FEA - Linear FEA
  • Autodesk Robot – Structural Modeling FEA (Skid Frames)
  • Autodesk Simulation Mechanical – Linear and Non-Linear FEA
  • Autodesk Simulation CFD
