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

Our company was established in 1988 as a custom Fired Heater fabricator. What set us apart was our commitment to perform all refractory installation with full-time HSI employees. As one of a select few custom fabrication companies with the capabilities and experience to self-perform refractory installation, we are able to keep your schedules on track, removing the uncertainty of subcontracting. Combining experience with our innovative maximum shop assembly method, HSI significantly reduces costs for our customers.

Custom Fabrication: More Than Just a Heater Company

The heart of the refinery, custom fabricated Fluidized Catalytic Cracking equipment has become our company’s specialty. An industry leader in fully completed and assembled equipment, HSI takes pride in our ability to manage the increasing challenges that large equipment fabrication entails. Whether you’re looking for a new Wye Blind and Distributor or a completed Reactor-Stripper, we have the experience and resources to meet your project needs.

Technical Expertise

Our company expertly fabricates custom-designed equipment from carbon steel to high-alloy and duplex materials. Often, projects require additional design and validation of previous designs. We have multiple engineers on staff who utilize state-of-the-art technologies to perform Finite Element Analysis (FEA) and other calculations to meet customer needs. Our primary software packages are Codeware COMPRESS, SolidWorks, SolidWorks Simulation, PV Elite, Ansys and several others. We take a meticulous approach to provide creative solutions for complex problems. Our goal is to work closely with clients and their engineering companies to deliver an excellent custom-fabricated mechanical design package.


Often a challenge for other custom fabrication companies, transportation can make or break a project. With access to the Port of Catoosa, HSI takes the guesswork out of your transportation equation. Whether we simply help coordinate our clients’ logistics, or fully manage the transportation phase of a project, our experience handling large equipment is an asset unique to this custom fabrication company.


Design & Expertise

With multiple ceramic engineers on staff, and involvement with development and application of API-936, our refractory technology far exceeds that of other custom fabrication companies in our industry. This means better system design, installation, quality and equipment reliability for you.


All refractory installation is performed by full-time HSI employees. We have dedicated teams of qualified installers for all types of refractory. Supervisors are tenured employees with years of experience in storage, handling, mixing and installation.

Safely and reliably providing high-quality custom fabrication and field services to refining, petrochemical, and power generation industries since 1988.
