Abstract: The invention refers to the means for monitoring and diagnostics of corrosion processes inside process vessels and pipelines. 
     Multi-layer construction element including outer elements and thermal insulation layer placed between them. The upper and lower surfaces of the outer elements of the multi-layer construction element are made with a longitudinal joint along the entire outer element. The multi-layer construction element additionally contains longitudinal connecting elements that are included in the joints of the upper and lower surfaces of outer elements. The multi-layer construction element is made with the possibility of both horizontal and vertical laying. Working joints for the electrical wiring duct are made in the thermal insulation layer. The outer elements can be made of glued beam, coreboard, plywood, bricks with a high degree of hollowness or stone. The thermal insulation layer can be reinforced. 
     A process line for the production of multi-layer construction elements, including the following interconnected elements: outer elements feeding unit, thermal insulation layer feeding unit, pressing unit, sawing unit, and removal unit for ready-made multi-layer construction elements installed on the frame. The outer elements feeding unit is equipped with a side feed conveyor for outer elements that is made in the form of a belt conveyor with the possibility of vertical orientation of outer elements during the installation on the conveyor. The outer elements feeding unit is equipped with two outer and middle guides. The thermal insulation layer feeding unit is designed to allow mixing of at least two components and supply of mixture between outer elements. The pressing unit is designed as a two-level belt conveyor. The frame in the area of the pressing unit is equipped with stands fixing the distance between the levels of a two-level belt conveyor, where each of these stands is equipped with a height adjuster of outer elements on the top. The upper level of the two-level conveyor is shorter than the lower level, and the central part of both levels is equipped with special dense stickers for the formation of the upper and lower working joints of the thermal insulation layer. The two-level belt conveyor of the pressing unit is equipped with paired thrust roller blocks that fix the outer dimensions of the multi-layer construction element. Axial roller blocks are made at the lower level of a two-level conveyor and at some distance from each other, and the first pair of thrust roller blocks is made in the area of the thermal insulation layer feeding unit. The sawing unit is made with the possibility of reciprocating motion of the saw with the speed of the conveyor belt movement. The removal unit for ready-made multi-layer construction elements is made in the form of a roller conveyor with a side unloader for ready-made multi-layer construction elements. 
     A method of production of multi-layer construction element including laying of outer elements, filling the space between outer elements with thermal insulation layer, aging and pressing of multi-layer construction element, and removal of finished multi-layer construction element from the process line. The outer elements are provisionally prepared by forming the upper and lower joint of each outer element. The outer elements are then fed with vertical orientation from two opposite sides. The outer elements are then fixed with guides. When the outer elements arrive at the insulation layer feeding unit, the outer elements are fixed with thrust roller blocks. Then the space between outer elements is filled with a thermal insulation layer, the components of which are pre-mixed, and the thermal insulation layer itself is fed from above. Then outer elements with a thermal insulation layer are fed into a two-level conveyor of the pressing unit, where the level of the second layer is fixed with stands, and the upper and lower levels of the conveyor forms the upper and lower working joints of the thermal insulation layer. After that, the outer elements with the thermal insulation layer are pressed for 7-10 minutes at a temperature of 20-65 °C. After that, the multi-layer construction element is fed into the sawing unit, where it is sawn to the specified lengths. The ready-made multi-layer construction elements are fed into the removal unit and then removed from the line by a side unloader.
