Frequently Asked Questions (FAQ)
What is Kingflex ULT designed for?
Kingflex ULT is specially developed for use on import/export pipelines and process areas of liquefied natural gas (LNG) facilities. It provides cryogenic thermal insulation and is part of a multi-layer configuration that delivers low-temperature flexibility to the piping system.
What are the recommended operating temperatures for Kingflex ULT and LT?
The recommended operating temperature range for Kingflex ULT is -200°C to 125°C, making it optimal for extreme cryogenic environments. For Kingflex LT, the recommended operating temperature range is -50°C to 105°C.
How does Kingflex ULT handle mechanical stress at low temperatures?
Kingflex ULT is built as a flexible, high-density, and mechanically robust closed-cell elastomeric foam. This material structure is designed specifically to overcome thermal and physical stress under extreme low temperatures while maintaining peak mechanical performance.
What is the cell structure of Kingflex ULT and LT insulation?
Both materials feature a closed-cell structural configuration, with a percentage of closed areas exceeding 95%. This high closed-cell ratio ensures superior thermal resistance and prevents moisture intrusion.
What standard sizes and dimensions are available for Kingflex insulation rolls?
Kingflex insulation is available in standard thicknesses of 3/4" (20mm) in 10 × 1 meter rolls (10 ㎡ per roll) and 1" (25mm) in 8 × 1 meter rolls (8 ㎡ per roll).
What standard test methods are used to verify the performance of these materials?
Performance and physical properties are verified using recognized industry standards, including ASTM C177 for thermal conductivity, ASTM D1622 for density, ASTM D2856 for closed cell structure, and ASTM E 96 for moisture performance and water vapor permeability.
