How to choose a rigid PIR insulation shell for polyurethane pipes

There are multiple factors to consider when selecting the appropriate specifications for the rigid PIR insulation shell of polyurethane pipes. Firstly, it is necessary to clarify the size and shape of the insulated pipeline or equipment to ensure that the pipe shell can fit tightly. Secondly, the required insulation thickness should be determined based on the insulation requirements and environmental temperature conditions. Usually, the lower the temperature and the higher the cooling requirements, the greater the required thickness.

High density PIR casing

High density PIR shell, also known as high-density polyisocyanurate shell, is a new type of organic polymer insulation material. It is made of isocyanate and polyether (Ployol) as main raw materials, together with catalyst, fire retardant and environment-friendly foaming agent. It is a foam polymer that is fully mixed, reacted and foamed under special formula and strict process conditions.
