The Industrial Insulation Standard for the 21st Century
Our Products
Excellent Thermal Performance: HITLIN™ E-glass can dramatically reduce heat loss (35% less compared to Calcium Silicate) in hot equipment and piping applications because of its exceptionally low thermal conductivity.
Excellent Dimensional Stability

The HITLIN™ Insulation Difference
28” HP Steam Line at SK Energy
SK Energy — HP Steam Pipeline
Problems
- The New FCC Unit would need 600# (42.3 kg/cm²g) HP steam for initial start-up operation. Steam (initially) to be fed from Point “A” on the map to New FCC.(After start-up, the New FCC Unit was designed to export steam back to the SK Energy power plant, Point “A”, in the existing refinery process area).
- Heat loss calculations indicated that, using their old industrial insulation standards (perlite), the steam temperature at point “A” was not hot enough to provide necessary steam conditions when it reached the New FCC. The minimum required HP steam temperature at the New FCC was 662°F (350°C).
- Heat loss calculations indicated that the actual temperature drop over the 2.6 mile (4.2 km) pipeline would be approximately 153°F (85.3°C)

Problem Solving
- Heat loss calculations were done considering HITLIN™ High-Density E-Glass instead of Perlite.
- SK Energy decided to use HITLIN™ High-Density E-Glass Insulation for the application.

Application Results
- The New FCC Plant was completed in June of 2008. When started-up, they experienced steam temperatures at the New FCC above 698°F (370°C).
- The resulting steam condition at the FCC was enough to operate more steam turbines than originally planned
Notes
- The thermal conductivity of HITLIN™ High-Density E-Glass and two other commonly used industrial insulation products are (@70°C):
- HITLIN™ - 0.028 (kcal/m·h·°C)
- Perlite - 0.047 (kcal/m·h·°C)
- Calcium Silicate - 0.053 (kcal/m·h·°C)
- The thermal conductivity of HITLIN™ is approximately 40% less than Perlite and 47% less than Calcium Silicate. These differences result in SIGNIFICANTLY LESS HEAT LOSS when using the HITLIN™ product.
Fact
- At today’s energy prices, using the wrong industrial insulation can result in extremely expensive heat losses. Consider:
- Let’s assume the subject 2.6 mile (4.2 km) 28” HP steam line was constructed with 4” of industrial insulation. The installed industrial insulation surface temperature (in service) measures 100°F (38°C). The average annual ambient temperature is 60°F (15.6°C). The average wind speed is 7 mph (3.1 m/s) and your energy cost is $0.10 per kWh. At these conditions, your energy costs would be $157 / ft*yr. That adds up to an annual energy loss of $2,155,300 --- over $2 million dollars.
- In this case study HITLIN™ use saved the customer over 1 million dollars by virtue of its superior thermal conductivity over Calcium Silicate.
- Visionary Insulation Products Ltd. will happily provide heat loss cost estimates for your specific applications.
