Abstract

Relating to the technical field of hot water pipe preparation, the invention discloses a heat preservation hot water pipe. The heat preservation hot water pipe consists of: a water pipeline cavity, apipeline cavity outer interlayer (heat preservation layer) and an outer layer. In the heat preservation hot water pipe prepared according to the invention, the pipeline interlayer design adopts heat preservation filler to fill the interlayer, the structure protection design of the water pipeline cavity outer layer reinforces the heat preservation effect, and all the layers are combined closely, the structure is stable, and the pipeline heat preservation material has high temperature resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, low temperature resistance,and is free of cracks, splits and other damages caused by repeated sudden change of high-low temperature difference in an external environment, the pipeline outer layer is durable, the service life islong, and the heat preservation hot water pipe can be used for long distance transportation of hot water, and decreases the water temperature reduction range.

Description

Technical field: [0001] The invention relates to the technical field of heat preservation of hot water pipes, in particular to a heat preservation hot water pipe. Background technique: [0002] In daily life or industrial production, long-distance and long-distance hot water supply needs are encountered. The hot water supply is generally transported through pipelines. At present, pipelines include polyurethane foam, stainless steel insulation pipes, PPR aluminum-plastic composite insulation pipes, Density polyethylene pre-embedded insulation pipe, PPR insulation pipe, PRC composite insulation pipe, etc. However, rubber and plastic materials have small thermal conductivity and good steam permeability resistance, which is convenient for construction, but they are not non-combustible materials. If they are used as heat preservation for high-temperature hot water pipes, they may be deformed, and the price is also slightly expensive. Centrifugal glass wool is a non-combustible m...
