Embodiment
[0047] A construction method for replacing the tank bottom heating plate, such as figure 1 shown, including the following steps:
[0048] S1: Prefabricated multiple arc-shaped heating plates. The heating plates are used to evenly and closely adhere to the bottom of the additive tank. Microholes are opened in the middle of the heating plate, and fixed ear seats are provided on both sides. Clean up within a width of 10-20mm on both sides of the weld, and use wire brushing or grinding to remove oxides, rust, oil, moisture and other substances that affect welding quality. Before the assembly, the surroundings of the welds should be cleaned with stainless steel polishing sheets. When assembling, pay attention to the uniformity of the weld seam, and the amount of misalignment is not more than 3mm. The heating plate is welded by argon arc welding, and the welding wire is 308 grade welding wire; the welding wire must be cleaned with a scrubbing solution before welding. In order to ...

The invention relates to the technical field of pipeline construction, and discloses a construction method for replacing heating plates at the bottom of tanks, including the following steps: S1: prefabricating a plurality of heating plates, the heating plates have micro-holes, and fixed ear seats are arranged on both sides; S2: process Isolation; S3: Remove the bottom insulation of the additive tank and the original heating plate; S4: Clean the bottom of the tank, polish the bottom of the tank with a steel ball, and then wipe its position with a clean rag; S5: Apply heat-conducting glue, the thickness of which is not less than 5mm; S6: Install the heating plate. The two ends of the installation position of each heating plate at the bottom of the tank are respectively equipped with spring-type fixed screw rods. Closely fit, the heat-conducting cement penetrates into the micropores; S7: Transform the steam pipe; S8: Test the pressure of the heating plate; S9: Install the tank bottom and steam pipe insulation; it has the advantages of less inspection steps and a short construction period.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a construction method for replacing a tank bottom heating plate. Background technique [0002] Additive tanks with heating plates are needed in lubricating oil chemical plants to store additives. After the plant is put into use for a long time, the heating performance of the additive tanks will not keep up with the increasing production requirements. The additive tanks need to be replaced. The additive tank area The order in which the additive tank heating plate is replaced is sequential. [0003] When the construction workers replace the additive tank, they first remove the outer insulation of the bottom of the tank, then remove the tank, and then install a new tank. The installation of the new tank must also repeat the system acceptance, and then restore the insulation after the acceptance is passed. . There is a protective cover at the bottom of some additive t...
