HSI’s refractory installation division is a world-class operation managed by experts specializing in this process critical field. Rigid guidelines are followed to maintain customer specifications and experienced craftsmen execute manufacturing plans with the highest level of technical expertise. From our staff of ceramic engineers to our installation craftsmen, HSI is committed to maintaining industry leadership in technology, performance, quality, and on-time delivery.  At HSI, refractory isn't a "next-step" operation to be subcontracted to dissinterested local third party, but rather is at the core of what we do.

Cast Vibrating

Our casting facility was custom designed to provide reliable continuous placement in a climate-controlled environment. Our complete understanding of the importance of batch control, temperature control, and material flow control is the basis of casting system design and process layout.  Specially trained craftsmen use state-of-the-art equipment and innovative techniques to manage complex vibration casting applications. From special temperature controlled material storage to careful weighing of each batch of material to a climate controlled casting pit, HSI controls all critical variables when vibration casting refractory materials.

Pneumatic Gunning

Our gunning process is managed by experienced personnel with the right equipment, using the right procedures. Careful integration of gunning installation with other refractory activities and fabrication steps allows HSI to optimize quality and assure on-time performance.


Modern erosion-resistant refractory products require careful attention to achieve desired properties and an acceptable installation. HSI crews have vast experience ramming all modern erosion-resistant refractory mixes. Our crews are familiar with custom anchors and anchor layout. Our engineers, designers, installers, inspectors and project managers are used to working to applicable engineering company, oil company and API RP 936 standards.
