Abstract
The invention relates to the technical field of pipes, in particular to a cold-resistant heat preservation conveying pipe. The cold-resistant heat preservation conveying pipe comprises an outer pipe and an inner pipe. A heat preservation layer and a heat conduction layer are arranged between the outer pipe and the inner pipe in sequence. An auxiliary heating device is arranged in the heat conduction layer. A resin layer is further arranged on the outer side of the outer pipe. According to the cold-resistant heat preservation conveying pipe, due to the facts that the heat preservation layer and the heat conduction layer are arranged between the outer pipe and the inner pipe, external cold air can be prevented from entering the inner pipe by the arrangement of the heat preservation layer; due to the fact that the heating device is arranged in the heat conduction layer, under the condition that the external temperature is low, heat can be provided for the conveying pipe through the heating device, and fluid in the pipe can be effectively from being frozen. Due to the fact that the resin layer is arranged outside the outer pipe, the outer pipe can be protected against frost damage when the external temperature is low.
Description
Technical field
The present invention relates to pipe fitting technical field, relate in particular to a kind of cold-resistant insulation delivery pipe.
Background technique
In construction engineering, the application of pipeline is to be seen everywhere, no matter be cold duct, gas pipe line, waterpipe etc., all for carrying indispensable requirement in life, for gas pipe line, what we more focused on is gas leakage and corrosion resistant effect, and for waterpipe, except the problems such as main leakage and corrosion, also must be noted that the insulation effect of pipeline, especially in the north, pipeline freezes and easily causes domestic water suffering or more seriously cause pipe burst, thereby affects people's normal life.
For the problems referred to above, we need a kind of can use under colder environment, and have preferably cold-resistant insulation effect, and can effectively prevent the cold-resistant insulation delivery pipe of pipeline bursting by freezing.
summary of the invention
