HPC vs. Conventional Cladding & Lagging Systems
In industrial settings, insulation is critical for energy efficiency, safety, and long-term asset protection. Traditionally, cladding and lagging systems have been the go-to solution, involving layers of insulating material (like fiberglass and mineralwool) wrapped in metal or other protective coverings. But are these conventional systems still the best option? Let's compare them to the innovative HPC (Hot Pipe Coating) manufactured by SPI Coatings.
1. Efficiency & Performance
- Conventional Systems: Typically require thick layers of insulation to achieve the desired thermal barrier, leading to significant bulk and potential heat loss at seams and joints.
- HPC Coating: Uses advanced ceramic compounds to form a highly efficient thermal barrier. It reduces heat transfer with a much thinner application, allowing it to outperform traditional methods while using less material.
2. Installation & Maintenance
- Conventional Systems: Installation can be labor-intensive and time-consuming, often requiring equipment shutdowns. Maintenance is also more complex, as cladding must be removed and replaced to inspect underlying surfaces.
- HPC Coating: Can be applied directly to hot surfaces without shutting down operations, drastically reducing downtime. It also simplifies maintenance by eliminating the need for cladding removal with NDT methods able to assess the substrate and internals such as DRT, PAUT & PEC.
3. Corrosion Prevention
- Conventional Systems: Cladding and lagging can trap moisture, leading to corrosion under insulation (CUI)—a costly issue in many industries both onshore and offshore.
- HPC Coating: Provides a seamless barrier that protects against moisture infiltration, effectively elliminating the risk of CUI.
4. Longevity & Durability
- Conventional Systems: Susceptible to wear and tear from environmental exposure, mechanical damage, and regular maintenance.
- HPC Coating: Offers long-lasting protection that resists environmental stressors, reducing the need for frequent repairs or replacements.
In summary, while conventional cladding and lagging have served industries for decades, HPC represents a significant leap forward in insulation technology and can deal with temperatures over 600C. It's more efficient, safer for workers, easier to apply and maintain and offers superior protection against corrosion. For industries looking to improve safety, reduce energy costs, and extend the life of their assets, HPC is a game-changer.
