Why Is Insulation Necessary And Why Do We Neglect It?

Professionals of industrial facilities have a common understanding as:
“Insulation is a very important parameter according to some very important reasons.”
However, insulation system is the very first part of the whole facility that is neglected easily. Starting from design phase and followed by maintenance and improvement needs are always behind the main process needs of the facility as it is a normal act according to some other important (!) reasons.

CINI – International Standard for Industrial Insulation

On July 28. 1989 CINI has been established to standardize the methods & specifications for industrial insulation and CUI (Corrosion Under Insulation) mitigation.


Conventional methods of industrial insulation applications are now supported and developed with different alternatives.
