Abstract
Length adjustment can be performed in a simple manner and without impairment of the insulating effect in an insulation cassette for the heat insulation of elongated elements. A multilayer insulation includes flat reflection elements (21, 22). Each layer of the insulation has at least two of the flat reflection elements (21, 22), which overlap at least partly at their ends (24) facing each other.
Claims20
An insulation cassette for the heat insulation of elongated elements, the insulation cassette comprising:
- a first cassette part;
- a second cassette part;
- a multilayer insulation comprising layers of insulation wherein each layer comprises at least two flat reflection elements, which overlap at least partly at ends facing each other;
- and
- a plurality of pushing guides arranged in an overlapping area between said first cassette part and said second cassette part, said pushing guides having an elongated hole in which a bolt is guided displaceably, said bolt being rigidly connected to an outer shell of said second cassette part and said bolt extending, in an outward direction, from said outer shell of said second cassette part, said bolt extending exclusively through the elongated hole associated with said first cassette part, whereby said elongated hole is arranged within an outer shell of said first cassette part.
A method to compensate changes in length because of thermal effects, the method comprising the steps:
- providing an insulation cassette for the heat insulation of elongated elements, the insulation cassette comprising a first cassette part, a second cassette part, a multilayer insulation comprising layers of insulation wherein each layer comprises at least two flat reflection elements, which overlap at least partly at ends facing each other and a plurality of pushing guides arranged in an overlapping area between said first cassette part and said second cassette part, said pushing guides having an elongated hole in which a bolt is guided displaceably, said bolt being rigidly connected to an outer shell of said second cassette part and extending, in an outward direction, exclusively from said outer shell through the elongated hole associated with said first cassette part to a position located beyond said first cassette part;
- and
- compensating for changes in length of an article because of thermal effects by using the insulation cassette as one or more of a compensating element to compensate changes in length of the article because of thermal effects and an adapter for variable length adjustment during assembly.
A method to insulate pipelines, the method comprising the steps:
- providing an insulation cassette for the heat insulation of elongated elements, the insulation cassette comprising a first cassette part, a second cassette part, a multilayer insulation comprising layers of insulation wherein each layer comprises at least two flat reflection elements, which overlap at least partly at ends facing each other and a plurality of pushing guides arranged in an overlapping area between said first cassette part and said second cassette part, said pushing guides having an elongated hole in which a bolt is guided displaceably, said bolt being rigidly connected to an outer shell of said second cassette part and only extending from said outer shell through the elongated hole defined in an outer shell of said first cassette part to a position located outside of said first cassette part;
- insulating cooling water pipes of nuclear power plants, in the area of branches with the insulation cassette.
