Abstract
The utility model is a flexible heat-preservation resinous tube comprising an inner pipe and an outer protecting pipe which is characterized in that a glue layer is arranged out of the inner pipe and a soft polyurethane expanded material layer is arranged between the glue layer and the outer protecting layer. The outer protecting pipe is a single-wall accordion pipe or a direct outer protecting pipe. The inner pipe is a PEX crosslinked polyethylene pipe by crosslinking treatment. The utility model has advantages of corrosion prevention, a good effect of heat preservation, energy saving, simple construction operation programs and construction difficulties, a smaller quantity of pipes and low costs.
Description
Technical field
The utility model relates to a kind of composite pipe that can any crooked high insulating effect.
Background technique
Existing moulding-plastic composite mainly contains glass fibre reinforced plastics and twines reinforced polyvinyl chloride pipe, PVC-polyethylene compound pipe, polyethylene compound pipe, silicon core pipe, polyethylene-polyurethane rigid foam plastic-polyethylene pipe etc., and the shortcoming of these composite pipes is can not be crooked, heat insulation effect is not ideal enough, how complicated, the body contact of construction easily causes leakage when using.
Summary of the invention
The purpose of this utility model provides a kind of composite pipe that has four-layer structure can any crooked high insulating effect, and it can overcome the above-mentioned shortcoming of existing composite pipe.
A kind of composite pipe that can any crooked high insulating effect has interior pipe, outer pillar, and there is sticker layer the outside of pipe in it is characterized in that, is soft polyurethane ester foaming material layer between this sticker layer and the outer pillar.
Simplify construction sequence and difficulty of construction when the utlity model has corrosion-resistant, high insulating effect, energy saving, use, reduce the pipe fitting use amount, advantage such as reduce cost.
Description of drawings
Accompanying drawing is a sectional structure schematic representation of the present utility model.
Embodiment
As shown in the figure, pipe 1, outer pillar 4 in the utility model has, there is sticker layer 2 outside of pipe 1 in it is characterized in that, is soft polyurethane ester foaming material layer 3 between this sticker layer 2 and the outer pillar 4.
Claims (3)
1, a kind of composite pipe that can any crooked high insulating effect, it is characterized in that having interior pipe (1), outer pillar (4), there is sticker layer (2) outside that it is characterized in that interior pipe (1), is soft polyurethane ester foaming material layer (3) between this sticker layer (2) and the outer pillar (4).
2, composite pipe as claimed in claim 1 is characterized in that described outer pillar (4) is single-wall corrugated pipe or the outer pillar of straight tube.
3, composite pipe as claimed in claim 1 is characterized in that described interior pipe (1) is the PEX crosslinked polyethylene pipe after crosslinking Treatment.
