Embodiment 1

[0055] A method for manufacturing a heat insulation block for anti-vibration heat insulation pipe support, which comprises the following steps:

[0056] (1) Preparation before manufacture;

[0057] 1) The ambient temperature for construction should be between 5°C and 35°C. When the ambient temperature is lower than 5°C, antifreeze measures should be taken; when the ambient temperature is higher than 35°C, cooling measures should be taken. The construction process should have good ventilation and Lighting, to prevent exposure to the sun and rain;

[0058] 2.) All equipment must be checked before construction, whether the metal surface has been sandblasted or manually derusted as required, whether all fastenings in the equipment are firm, whether the welding and installation of anchor nails or insulation nails are qualified;

[0059] 3.) Water, rust, oil, slag and other debris on the equipment must be removed before construction, so as not to affect the strength of the material...

Abstract

The invention relates to a shock-resistance and heat-insulation pipe bracket and a heat-insulation block technology. A heat-insulation block for the shock-resistance and heat-insulation pipe bracket is formed by mixing lightweight aggregate, various light micro powder, coal ash, aggregate composed of vermiculite, alkali-free glass fibers, expanded perlite, aluminate cement and water according to a certain ratio, and the shock-resistance and heat-insulation pipe bracket is obtained after dry mixing, wet mixing and processing forming. The heat-insulation block can bear the high temperature of 1000 DEG C, the heat conduction coefficient under the temperature of 550 DEG C is smaller than or equal to 0.15 W / mk, the compressive strength is larger than or equal to 10 MPa, and the breaking strength is 4.5-6 MPa. Meanwhile, multiple functions of shock resistance, sound absorption, heat insulation and the like are achieved, the shock-resistance and heat-insulation pipe bracket is used for replacing a heat-insulation pipe bracket formed by processing traditional aggregate, and shock resistance and the heat insulation effect of the traditional heat-insulation pipe bracket are greatly improved.

Description

technical field [0001] The invention relates to a pipeline technology, in particular to a pipeline heat insulation technology, in particular to a heat insulation block for anti-vibration heat insulation pipe support and a manufacturing method thereof. Background technique [0002] With the application of new high-efficiency thermal insulation materials and the continuous improvement and perfection of thermal insulation structures, the thermal insulation level of existing steam pipelines has been greatly improved, but the heat loss and safety performance of pipe support has not yet attracted widespread attention. At present, most of the heat-insulating pipe support products in the market use ordinary castables. This type of pipe support has high compressive strength, but it is relatively bulky and inconvenient to install. It is easy to crack; especially when it is applied to the medium and high pressure long-distance steam transmission pipeline, the alternating stress and dyn...
