Frequently Asked Questions
Does this ULT system require an external moisture barrier?
No, the flexible ULT insulation system does not require an additional moisture barrier. Its unique closed-cell structure and advanced polymer blend formulation natively provide high resistance to water vapor permeation.
What is the operating temperature range for the ULT and LT materials?
The ULT material is designed for extreme low-temperature applications, functioning from -200°C to 125°C. The LT material is suitable for temperatures from -50°C to 105°C.
How does this insulation prevent Corrosion Under Insulation (CUI)?
The closed-cell structure prevents moisture ingress, which is the primary cause of CUI. Additionally, both ULT and LT materials feature a neutral-to-alkaline pH value (≥8.0), reducing the risk of chemical corrosion on metal pipes.
What are the thermal conductivity properties of the ULT insulation?
The ULT material demonstrates outstanding thermal resistance with low thermal conductivity values of 0.028 W/(m·K) at -100°C and 0.021 W/(m·K) at -165°C under ASTM C177 testing standards.
Can these materials be easily installed on complex pipe shapes?
Yes. Because the elastomeric material retains its flexibility even at extremely low temperatures, it can be easily cut, wrapped, and installed around complex fittings, valves, and tight geometries.
What standard sizes are available for the insulation rolls?
The rolls are available in two standard specifications: 3/4" (20mm thickness, 10 × 1 m size, 10 ㎡/roll) and 1" (25mm thickness, 8 × 1 m size, 8 ㎡/roll).
