Abstract
The utility model discloses an oxygen resisting type aluminum alloy lining plastic composite pipe, which is composed of a plastic inner pipe and a metal outer pipe. The plastic inner pipe is a heat resisting polyethylene inner pipe; the metal outer is an aluminum alloy oxygen resisting pipe; a layer of aluminum alloy oxygen resisting pipes are covered on the outer surface of the heat resisting polyethylene pipe. The oxygen resisting type aluminum alloy lining plastic composite pipe has the advantages of reasonable design, simple structure, good oxygen resisting effect, ultraviolet radiation resistance, strong ageing resistance and high surface strength, and can be widely applied to industrial and civil hot and cold water system, hot water heating system and drinking water system.
Description
Technical field
The utility model relates to a kind of composite pipe, particularly relates to a kind of serviceability temperature at the oxygen-resistance type aluminum alloy lining plastic composited pipe below 80 ℃.
Background technique
Heat-proof polythene (PE-RT) is a kind ofly to be formed by vinyl monomer and 1-octene monomer copolymerization, and this copolymer has formed a kind of 6C of having long branched chain structure.Between the molecular chain and mutual unordered winding between the long branched chain, form " space network ", the formation of this special construction improves the mechanical property of material and the croop property of opposing external carbuncle effect greatly, improved its thermostability, long-term hydrostatic intensity, anti-slow crack growth (SCG) and quick crack extesion (RCP) performance.Be widely used in industry and civilian hot and cold water, potable water and hot water system.But PE-RT tubing is also the same with other plastic tube, exists to ooze the oxygen phenomenon.When exposing tubing more than ground and touch air, airborne oxygen can penetrate into from the surface of tubing in the pipe and go the medium (water), because the content of the oxygen in the medium (water) increases, make some hardwares such as steel pipe fitting, cast-iron radiator etc. in the pipe-line system, very easily be subjected to the corrosion of oxygen-containing medium, thereby shortened working life of system, in addition, exposed plastic tube also very easily is subjected to the infringement of solar ulatraviolet radiation and the damage that the surface is impacted.
The model utility content
The purpose of this utility model is the deficiency that exists at prior art, provides that a kind of cost of production is low, the resistance oxygen-resistance type aluminum alloy lining plastic composited pipe that oxygen is effective, anti-uv-ray is strong, aging quality resistance is strong and surface strength is high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of oxygen-resistance type aluminum alloy lining plastic composited pipe, form by plastic inner pipe and metal outer pipe, it is characterized in that described plastic inner pipe is a pipe in the heat-proof polythene, described metal outer pipe is an aluminum alloy resistance oxygen pipe, is coated with layer of aluminum alloy resistance oxygen pipe in heat-proof polythene on the outer surface of pipe.
The utility model compared with prior art has the following advantages:
(1) the utility model is reasonable in design, and is simple in structure, specious, installs easy to connect;
(2) oxidation prevention layer adopts aluminum alloy material, has 100% resistance oxygen effect, thereby has reduced in the pipe oxygen content in the medium (water), has reduced the corrosion to metal pipe element, cast-iron radiator etc. in the system, has prolonged system working life;
(3) ultraviolet radiation resisting, aging quality resistance is strong;
(4) increase tubing intensity, improved anti-damage of tubing and shock proof performance.
