Light high-strength heat insulation pipe support

Abstract

The invention provides a light high-strength heat insulation pipe support. The pipe support comprises an arc-shaped lower hoop and an arc-shaped upper hoop, wherein the lower portion of the lower hoopis supported through a supporting bottom plate, the upper hoop and the lower hoop are connected in a fastened mode through at least two fastening devices, and a flexible heat insulation layer, a heatreflection layer and a heat insulation layer are sequentially arranged on the inner side of the upper hoop from inside to outside; and a flexible heat insulation layer, a heat reflection layer, a heat insulation coating, a heat insulation block and a flexible heat insulation gasket are sequentially arranged on the inner side of the lower hoop from inside to outside. An outer hoop fastener and a hard heat insulation layer are made of light materials, the overall weight of the pipe support is effectively reduced, transportation and installation are convenient, the flexible heat insulation gasket and the ultra-hard nano ceramic heat insulation coating are additionally arranged, the overall compression resistance and fracture resistance of the pipe support are enhanced, and the heat reflection layers and the low-heat-conductivity-coefficient flexible heat insulation layers are adopted, so that the overall heat insulation performance of the pipe support is improved.

Description

technical field [0001] The invention relates to a matching installation equipment for pipelines, in particular to a light-weight and high-strength heat-insulating pipe support for supporting long-distance steam pipelines. Background technique [0002] The pipe support bracket is the supporting device of the steam pipe. When it is working, it will conduct heat through the support plate and rib plate and dissipate heat through the bottom plate, and transfer a large amount of medium heat to the atmosphere. According to the calculation and actual measurement, the heat loss of the pipe support accounts for about 20% to 30% of the total heat loss of the pipe. Therefore, it is necessary to focus on heat insulation for this part. At present, the commonly used heat insulation pipe support is mainly assembled by castable hard heat insulation material, ceramic fiber blanket soft heat insulation material and steel pipe clamp. The castable hard heat insulation material used in this type...

AI Technical Summary

Problems solved by technology

The castable hard heat insulation material used in this type of heat insulation pipe support is in direct rigid contact with the steel pipe clamp. During the work process, it needs to continuously bear the high impact load brought by the instantaneous stress, and it is easy to crack and break after a long time. Affect its heat insulation and support effect, reduce its service life

In order to achieve higher compressive and flexural strengths, the density and weight of castable hard heat insulation materials will be high, and the use of high-quality steel pipe clamps will result in the overall weight of heat insulation pipe holders Very large, Chinese patent 201610044887.3 Although the weight of the pipe support is reduced by removing the upper half of the hard insulation material, the pipe support is still relatively heavy, which brings great inconvenience to transportation and installation

The normal temperature thermal conductivity of soft insulation materials such as ceramic fiber blankets used in traditional heat insulation pipe support is about 0.056 W / m K, the heat insulation performance is average, and the energy loss caused by heat radiation cannot be effectively prevented.

Therefore, due to the influence of steel structure and castable hard insulation materials, the traditional heat-insulated pipe support cannot meet the long-term safety and energy-saving requirements of steam pipelines during use.
