The present invention provides a PP-R double insulating pipe, which comprises an inner pipe and a outer pipe, a connection tendon is arranged between the inner pipe and the outer pipe. The spacing between the double pipes forms a room, because the air in the room is stable comparatively, the heat transmission is reduced, and the heat preservation effect is obtained.
Description
technical field [0001] The invention relates to a water pipe, in particular to a double-layer PP-R water pipe. Background technique [0002] The PP-R pipes currently on the market are all single-layer, and the insulation performance is not good enough. Contents of the invention [0003] The present invention has invented the PP-R double-layer thermal insulation pipe according to the disadvantages of poor thermal insulation of the above-mentioned water pipes and waste of energy. [0004] The PP-R pipe of the present invention is a plastic pipe, and PP-R is its international code name. The advantages of this kind of pipe are: high hardness, good toughness, temperature resistance up to 110°C, good heat preservation, the biggest advantage is that the joints are connected by hot melting, which can ensure that the connected pipes are well sealed and connected Strong, and the PP-R material does not age for up to 30 years. The pipe is widely used in hot water pipe projects, suc...
