Abstract
The invention discloses a hard polyurethane foam plastic spraying heat preservation pipe and a spraying method. The conventional hard polyurethane foam plastic spraying heat preservation pipe has super-high heat preservation effect in the low-cold regions in China; when the conventional hard polyurethane foam plastic spraying heat preservation pipe is used in northern high-cold regions, the problem of low heat preservation effect is caused due to uneven distribution of lowest temperature of the natural environment and the specified standard thickness of the polyurethane heat preservation layer, resulting in that the energy consumption is improved and the carbon emission is increased. The hard polyurethane foam plastic spraying heat preservation pipe comprises a working pipeline and a hard polyurethane plastic foam spraying heat preservation layer, wherein the hard polyurethane plastic foam spraying heat preservation layer (2) is arranged outside the working pipeline (1); the working pipeline is a hard straight pipeline; the material of the working pipeline is a steel pipe or a plastic pipe. The invention is applied to the hard polyurethane foam plastic spraying heat preservation pipe and the spraying method.
