Method for testing and for an inspection of a functionality of an insulation work on industrial installations, especially of an insulation surrounding a pipe; system comprising a pipe especially for transport of cooled media, and insulation for such a pipe

A system comprising a pipe especially for a transport of cooled media, an insulation, a valve, a pump and a gauge, whereby the insulation comprises at least an insulation element, preferably of an open porous material, especially made of bound mineral fibres, and a vapor barrier surrounding the insulation in an airtight manner at all ambient faces, whereby the valve connects the inner part of the insulation with the surrounding area and is connected or connectable to the insulation element, whereby the pump is connectable to the valve for increasing or decreasing the inner air pressure of the insulation to a predetermined pressure, and whereby the inner pressure is displayed on the gauge.

An insulation for a pipe, especially for transport of cooled media, comprising at least one insulation element, preferably of an open porous material, especially made of bound mineral fibres, and a vapor barrier surrounding the insulation in an airtight manner at all ambient faces,

• wherein
• the insulation element is provided with a valve allowing to increase or to decrease the inner air pressure of the insulation element by a pump to a predetermined pressure.
