High temperature pipeline heat insulation clamp without two wing ear plates

Abstract

The invention relates to a double wing lug plate-free double-clip bolt buckle high-temperature pipeline heat insulating clamp, which comprises an upper semicircular clamp and a lower semicircular clamp, and is characterized in that the two ends of the upper clamp and the lower clamp are not provided with lug plates; male bolt buckles or female bolt buckles are connected to the two ends of the upper clamp; female bolt buckles or male bolt buckles are connected to the two ends of the lower clamp; the upper clamp and the lower clamp are spliced into a circular clamp which can be used for clamping a medium pipeline; and the two ends of the upper clamp and the two ends of the lower clamp are connected through the male bolt buckles and the female bolt buckles respectively, and are fastened through nuts. The double wing lug plate-free double-clip bolt buckle high-temperature pipeline heat insulating clamp has the advantages of simple and ingenious structure, low construction cost, lighter weight than pipeline clamps of the same type, convenience for pipeline heat preserving construction, long pipeline service life, low running cost, and particular suitability for buried casings; and the diameters of the buried casings can be about 200-300 millimeters smaller than that of the conventional buried casing, so that the construction investment on the buried casing is reduced.

Description

technical field [0001] The invention relates to a supporting device for pipeline equipment, in particular to a pair-clip type bolt buckle heat insulation clamp for high-temperature pipelines without two wing ear plates. Background technique [0002] At present, the brackets of high-temperature pipeline equipment generally use clip-on clamps with two-wing ear plates to support the pipeline and meet the thermal displacement requirements of high-temperature pipelines, but they have some defects: [0003] 1. The lug plates of the two wings are usually about 50~150mm larger than the outer diameter of the pipe after insulation, which makes it difficult to realize the waterproof function of the protective layer of the pipe insulation, greatly shortening the service life and heat preservation effect of the insulation material, so that the long-term operation of the pipeline reduces the heat loss. Large, the energy consumption cost of pipeline operation will increase. [0004] 2. Si...

Problems solved by technology

[0003] 1. The lug plates of the two wings are usually about 50~150mm larger than the outer diameter of the pipe after insulation, which makes it difficult to realize the waterproof function of the protective layer of the pipe insulation, greatly shortening the service life and heat preservation effect of the insulation material, so that the long-term operation of the pipeline reduces the heat loss. Large, the energy consumption cost of pipeline operation increases

[0004] 2. Since the tangent line between the ear plates of the two wings and the hoop diameter is 90o, in order to ensure the strength of the hoop to clamp the pipe and the rigidity of the ear plates of the two wings, the thickness of the hoop steel plate must be thickened, so that the manufacturing of the brackets for the ear plates of the two wings Increased costs

[0005] 3. Because the ear plates of the two wings are exposed outside the insulation layer, it will have a negative impact on the aesthetics of the urban pipeline design

[0006] 4. Because the ear plates of the two wings are exposed outside the insulation layer, for the design of urban buried casing pipelines, the diameter of the buried casing is usually about 300mm larger than the diameter of the medium pipeline, which increases the construction investment cost of the buried casing pipeline
