Problems solved by technology
[0003] When in use, the tube sheet is generally in contact with industrial cooling water or other chemical media. Impurities, salts, gases, and microorganisms in industrial cooling water will cause corrosion to the tube sheet and welds, reducing the service life of the tube sheet. It is welded on the tube sheet, and it is difficult to disassemble, which increases the difficulty of replacement and keeps the maintenance cost high

The invention discloses a double-layered composite pipe plate. The double-layered composite pipe plate comprises a top-layer panel and a bottom-layer fixed plate, wherein the top-layer panel is arranged on the upper surface of the bottom-layer fixed plate in parallel; a plurality of hollow pipes are connected between the top-layer panel and the bottom-layer fixed plate; a plurality of top ladder holes are formed in the top-layer panel; the bottom-layer fixed plate is provided with a plurality of bottom ladder holes matched with the top ladder holes respectively; the upper parts of the hollow pipes are arranged in the top ladder holes respectively; the lower parts of the hollow pipes are arranged in the corresponding bottom ladder holes respectively; and the top-layer panel and the bottom-layer fixed plate are fixed by a bolt. With the adoption of the manner, the double-layered composite pipe plate can utilize the match of the top-layer panel and the bottom-layer fixed plate, and the hollow pipes are flexibly fixed between the top-layer panel and the bottom-layer fixed plate and do not need to be welded; and the double-layered composite pipe plate is relatively convenient to assemble and disassemble, and the post-period maintenance cost is reduced.
Description
technical field [0001] The invention relates to the field of tube sheet design, in particular to a double-layer composite tube sheet. Background technique [0002] The tube sheet is a fitting with tubes embedded in the steel plate. First, holes are drilled on the tube sheet, and then the tubes are installed in the holes and welded to form the tube sheet. [0003] When in use, the tube sheet is generally in contact with industrial cooling water or other chemical media. Impurities, salts, gases, and microorganisms in industrial cooling water will cause corrosion to the tube sheet and welds, reducing the service life of the tube sheet. It is welded on the tube sheet, and it is difficult to disassemble, which increases the difficulty of replacement, and the maintenance cost remains high. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a double-layer composite tube sheet, which improves the efficiency of installatio...
