Frequently Asked Questions (FAQ)
Q1: What temperature range is the Kingflex ULT insulation system suitable for?
A1: The Kingflex ULT insulation system is recommended for operating temperatures ranging from -200 °C up to +125 °C, making it highly effective for extreme cryogenic applications.
Q2: How does the system handle structural movement and vibration?
A2: The system can be directly installed on piping equipment even under temperatures as low as -110°C when the surface temperature is below -100 °C, especially in setups where pipelines undergo repeated movement or vibration.
Q3: What are the key structure features of Kingflex ULT?
A3: It features a multi-layer composite closed-cell structure with a high closed-area percentage of over 95%. This configuration provides excellent thermal resistance and minimizes moisture penetration.
Q4: Does the insulation system help prevent corrosion under insulation (CUI)?
A4: Yes, the multi-layered design and low moisture permeance significantly minimize the risk of moisture ingress, which is the primary cause of corrosion under insulation (CUI).
Q5: Is the insulation installation complex?
A5: No, the system is designed for ease of installation. It requires fewer seams to provide a faster and more secure installation, adapts easily to awkward shapes, and reduces the use of hazardous components.
Q6: What standards does Kingflex ULT comply with for thermal conductivity?
A6: The thermal conductivity performance of Kingflex ULT is tested and measured in accordance with recognized international standards, including ASTM C177 and EN 12667.
