Elbow pipe anti-abrasion cover

Abstract

The invention discloses an elbow pipe anti-abrasion cover which comprises an elbow pipe, an anti-abrasion cover, clamp rings and an anti-abrasion cover cap plate. The elbow pipe anti-abrasion cover is characterized in that the anti-abrasion cover is connected and mounted on the elbow pipe through the clamp rings; a gap of 3-4cm is provided between the anti-abrasion cover and an adjacent anti-abrasion cover; the anti-abrasion cover cap plate is arranged in the gap; the anti-abrasion cover cap plate and the anti-abrasion cover are integrally stamped, processed and formed; a steel plate which is in lap joint between the anti-abrasion cover and the cover plate is removed; the use of the steel plate is reduced; a fillet welding seam which is in lap joint between the anti-abrasion cover and the cover plate is avoided; workload of welding and clearing is reduced; the use of a welding material is reduced; assembly efficiency is improved; product quality is improved; appearance is attractive; and cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a wear-resistant cover for an elbow. Background technique [0002] In the production process of high-pressure boilers, due to the high pressure of the boiler, the pipes conveying the heat medium must also bear corresponding high pressure. When the wall thickness of the pipe system is worn below the wall thickness allowed by the design, it may be damaged. Leakage, pipe burst, etc. will cause the boiler to shut down, causing losses to the operating unit and the gas and electricity unit. Boiler serpentine elbow products are used to prevent the flue gas from washing the pipe and prolong the service life of the product. Usually, the flue gas in the pipe A wear-resistant cover is added to the windward side to prevent the wear of the pipe. At present, considering that the serpentine elbow is heated and expanded in the flue, a gap will be reserved between the wear-resist...

Problems solved by technology

[0002] In the production process of high-pressure boilers, due to the high pressure of the boiler, the pipes conveying the heat medium must also bear corresponding high pressure. When the wall thickness of the pipe system is worn below the wall thickness allowed by the design, it may be damaged. Leakage, pipe burst, etc. will cause the boiler to shut down, causing losses to the operating unit and the gas and electricity unit. Boiler serpentine elbow products are used to prevent the flue gas from washing the pipe and prolong the service life of the product. Usually, the flue gas in the pipe A wear-resistant cover is added to the windward side to prevent the wear of the pipe. At present, considering that the serpentine elbow is heated and expanded in the flue, a gap will be reserved between the wear-resistant cover and the wear-resistant cover, and the wear-resistant cover plate is welded at this position. Because the welding position of the wear-resistant cover plate is all-position welding, the welding skills of the welders are high during assembly and welding, and the weld seam is not beautiful, so it is necessary to modify the existing equipment
