Technical Field

The invention relates to a pipeline matching installation device, in particular to a light high-strength heat insulation pipe bracket for supporting a long-distance steam transmission pipeline.

Background

The pipe bracket is a supporting device of the steam pipeline, and can conduct heat and dissipate heat of the bottom plate through the supporting plate and the ribbed plate during working, so that a large amount of medium heat is transferred to the atmosphere. The calculation and actual measurement show that the heat loss of the pipeline bracket accounts for about 20% -30% of the total heat loss of the pipeline, so that the part needs to be subjected to important heat preservation and heat insulation. The conventional heat insulation pipe support is mainly formed by assembling a castable hard heat insulation material, a ceramic fiber blanket soft heat insulation material and a steel pipe clamp. The hard thermal insulation material of the castable used by the thermal insulation pipe support is in direct rigid contact with the steel pipe clamp, needs to continuously bear higher impact load caused by instantaneous stress in the working process, is easy to crack and break after a long time, influences the thermal insulation and supporting effects of the thermal insulation pipe support, and reduces the service life of the thermal insulation pipe support. In order to achieve higher compression strength and bending strength, the density of the castable hard heat insulation material is very high, the weight is very large, and in addition, a steel pipe clamp with large mass is used, so that the whole weight of the heat insulation pipe support is very large, although the weight of the pipe support is reduced by removing the upper half part of the hard heat insulation material in the Chinese patent 201610044887.3, the whole pipe support is still heavy, and great inconvenience is brought to transportation and installation. The soft heat-insulating material such as ceramic fiber blanket used in the traditional heat-insulating pipe bracket has the normal-temperature heat conductivity coefficient of about 0.056W/m.K, the heat-insulating property is general, and the energy loss caused by heat radiation can not be effectively prevented. Therefore, the traditional heat insulation pipe support is influenced by a steel structure, a castable hard heat insulation material and the like, and the requirements of long-term safety and energy conservation of a steam pipeline cannot be met in the using process.
