Abstract

PURPOSE:To facilitate the fitting of a heat insulating material to a tank by stretching hooking wires with spring via supporters so as to maintain the same distance as the thickness of a plate-like heat insulating material and covering the tank surface with the heat insulating material while suppressing it with the wires. CONSTITUTION:Supporters 2 are erected at a proper distance on the outer surface of a tank forming a spherical hull and an element plate 1, metal bars 2' are inserted via through holes of the supporters, and elastic hooking wires 4 with spring 3 are stretched between two adjacent metal bars at a proper distance on the metal bars. The wires 4 are provided so as to maintain the same distance as the thickness of a plate-like heat insulating material 5 used from the tank surface and cover the tank surface while suppressing the heat insulating material 5 with the springs.

ある。[Detailed Description of the Invention] Large tanks such as LPG liquefied gas storage tanks, which are made by welding raw single plates, are used for the purpose of improving construction efficiency, reducing structural costs, and depending on the plate thickness, eliminating welding residual stress. It is necessary to perform a heat treatment on the entire surface. However, since there is no large 11-blunt furnace capable of accommodating the large tank of the Hibi type, this must be carried out outdoors. Even though external heat treatment is unavoidable, it is desirable to provide as much of the same thermal history as possible during heat treatment in an annealing furnace. Therefore, the tank is covered with insulation and insulated. For this purpose, it is necessary to (1) make effective use of the amount of heat used to heat the tank and heat it uniformly without dissipating it outside the tank, and (2) avoid sudden cooling when cooling.

As shown in the figure, the surface of the tank is piled up while holding the plate-shaped heat insulating material 5 in sequence with a spring.

As a result, the heat retention material becomes stronger due to the action of the spring, and the heat insulation material adheres to the tank throughout the heat treatment period, so the power yk of the present invention is said to be an ideal method for heat retention of tanks undergoing heat treatment outside the brewery. You get it.
