Description

Design specifications for storage tanks containing cryogenic fluid such as liquefied natural gas (LNG), ethylene or nitrogen for chemical or combustion processes, are not only highly demanding in terms of construction, but also in terms of insulation. With the tank volume expanding and contracting depending on the level of liquid inside, the insulation must offer high levels of both compressibility and resilience. To meet this requirement, ISOVER has developed the unique CRYOLENE product range.

CRYOLENE 684 has been designed for the insulation of cryogenic pipe expansions. The properties and performance of CRYOLENE 684 have been extensively tested by external institutes and the products are well-proven through decades of successful use worldwide in chemical and LNG applications.
