INDUSTRIAL INSULATION SUPPLIER

Partner with SPI to Address Common Industrial Challenges

We work alongside industrial insulation contractors to deliver solutions for complex industrial projects. As both a fabricator and distributor, we provide insulation solutions to help you address various challenges. 

.Temperature Control

Maintaining temperatures in industrial facilities is crucial for process efficiency and equipment longevity. Our thermal insulation solutions can improve thermal stability across a wide range of temperature applications. We also understand how in industrial insulation, the external environment can be just as important when selecting the combination of materials for your application. SPI is here to serve as your unbiased partner and can walk you through the pros and cons of any materials for your specific project or application.

Freeze Protection

The right insulation solution can provide freeze protection at industrial facilities by reducing heat loss from pipes, valves, and equipment exposed to harsh cold environments outdoors. By maintaining above-freezing temperatures, insulation helps prevent water, chemicals, or other process fluids from freezing, which can block flow or rupture pipes. Proper insulation systems can prevent cracked or burst lines, which result in costly repairs, shutdowns, or even environmental hazards. Our solutions can help ensure your systems run smoothly during winter, minimizing downtime and maintaining productivity.

Corrosion Under Insulation

Proper insulation selection reduces the risk of corrosion under insulation (CUI), supporting the longevity of industrial equipment. CUI occurs most often at operating temperatures between 100°F and 350°F (38°C – 177°C), in the presence of oxygen, liquid water, or corrosive chemical components, and when PH levels drop below seven (7).

Some of the points in an insulation system that can be vulnerable to CUI include elbows, irregular shapes like valves and accessories, any jacket penetration and termination locations, as well as any locations for potential hydrocarbon leakage (e.g. low-points, flanges, valves, and couplings). SPI can partner with you to identify the best possible insulation products to prevent CUI-related issues, including accessories such as drain plugs, access plug flanges, and joint sealant. We also encourage implementing consistent inspection and maintenance practices on site.

Excessive Noise and Vibration

Industrial environments require noise reduction solutions to increase safety and operational efficiency. Many of our insulation materials can minimize sound transmission and vibration, creating a more controlled environment.

Personnel Protection

Industrial insulation solutions can support and protect personnel on industrial sites in a multitude of ways. These include:

• Preventing burns or other heat-related injuries through thermal protection
• Reducing the risk of slips and falls by preventing condensation
• Lowering the risk of hearing damage with acoustic insulation
• Fire safety with the application of fire-resistant materials that will slow the spread of fire, giving personnel more time to evacuate

Compliance With Regulations and Safety Standards

Meeting industry regulations requires insulation that aligns with strict safety and performance criteria. Proper insulation in an industrial setting can improve personnel protection by reducing the risk of burns and injuries, minimizing fire spread, and protecting equipment from damage.

Fire Protection

Industrial facilities benefit from insulation materials that enhance fire safety. We offer fire-rated solutions designed to protect equipment and structures as well as limiting the spread of fire and smoke, preventing injuries and reducing damage to valuable equipment. As your partner in insulation, we can walk you through which products would offer the best fire protection for your application.

Reducing Emissions and Energy Costs

Reducing energy consumption remains a priority in industrial settings. Our insulation solutions improve energy efficiency by minimizing heat loss and optimizing thermal control.
