The invention provides a nuclear power plant device and a composite type insulating layer used for a pipeline. The composite type insulating layer is made by a plurality of independent insulating blocks in a lap joint mode; when temperature of the nuclear power plant device or outer wall of the pipeline is higher than 200 DEG C, the insulating blocks sequentially fill an inner insulating layer, a first supporting layer, a neutron shielding layer which wraps isolation materials, a second supporting layer, a gamma shielding layer, a third supporting layer and an outer insulating layer in a shell. When the temperature of the nuclear power plant device or outer wall of the pipeline is lower than 200 DEG C, the insulating blocks sequentially fill the neutron shielding layer which wraps the isolation materials, the second supporting layer, the gamma shielding layer, the third supporting layer and the outer insulating layer in the shell. On the basis of meeting insulating requirements, the nuclear ...
