HSI: A World-Class One-Stop Custom Fabrication Company

Our goal as a custom fabricator is to provide engineering support to our clients and their engineering company. We can incorporate loadings, fatigue analysis, thermal analysis and lifting/transportation as required.

In-House Engineering for Custom Fabrication

Custom-fabricated equipment can be fully designed by in-house engineers. Our engineering team performs all necessary calculations, including Finite Element Analysis (FEA). With software such as Compress, Solidworks Simulation, PV Elite and others, our engineers evaluate designs for each vessel, with special attention to the wall thickness and stress requirements for towers, vessels and other process equipment. Additionally, our in-house engineering department stands out within the custom-fabrication industry due to our ability to provide service for complex projects.

Finite Element Analysis (FEA)

Finite Element Analysis (FEA) is simply an alternative method to validate or verify appropriateness of design in situations where classical methods or traditional rules of code are insufficient. FEA software is an integral asset employed to design optimal components.

Thermal Analysis for Refractory Lined Products

In some cases, a thermal analysis is required to determine the correct material and thickness combination. When appropriate, we can perform thermal analysis for our clients in an effort to help validate their selections.

We use various combinations of the following software:

  • Codeware COMPRESS
  • PV Elite
  • MDSolids
  • SolidWorks & SolidWorks Simulation Professional (formerly Cosmos)
  • Inventor
  • AutoCAD
  • MathCAD

Engineering Team

When engaged early in the design process, our engineering team can provide valuable input well before detailed design and fabrication. Often, engineering contractors do not have the insight of professionals who build custom equipment daily and potentially overlook issues during the FEED phase of a project. Partnering with HSI early reduces costly late design changes and can reduce the lead time of equipment after purchase.

Code Requirements

HSI can perform required design calculations to a variety of nationally recognized codes including American Society of Mechanical Engineers (ASME) Section I, Section VIII Div. 1 and 2 as well as B31.1 and B31.3. We currently hold ASME S, U, U2 and National Board R stamps. In addition to the rules contained in the aforementioned codes, we understand our clients have their own specific requirements that we incorporate during the design and fabrication phase.
