3.18.4. Insulation and lining

In the presence of insulation, for automatic weight accounting, you should specify its thickness, as well as density or mass (for complex heterogeneous insulation). When assigning insulation, the program takes into account the change in the outside dimension of the component, when calculating wind loads.

Thickness and density of insulation can be selected from database according to the current regulations (Fig. 3, 4).

By selecting "Calculate" option,you can receive a lot of components of thermal insulation via the calculation module of the Insulation program. Input data for calculation are the geometric dimensions of the model component, its temperature, climatic parameters and project data specified in the  dialog "Data for calculation of insulation".

Option "Presents in test/assembly conditions” influences on weight of the component and its outside ("wind") diameter in appropriate conditions.

In the presence of lining, for automatic weight accounting, you should specify its thickness and density.

For some components (shell, head), it is possible to take lining as plating (double-layer steel wall, Fig. 4). At that, the calculation takes into account the wall thickening and changes in allowable stresses.

For tube sheets of heat exchangers, two-sided cladding with recalculation of the allowable stresses of the carrying layer is provided (Fig. 5).
