Abstract
The utility model relates to a plastic composite pipe which comprises a chlorinated polyvinyl chloride outer pipe and a random copolymerized polypropylene inner pipe arranged in the chlorinated polyvinyl chloride outer pipe by cold drawing. By adopting the technical scheme, the utility model provides the plastic composite pipe which is heat-resistant, environment-friendly and high in using strength.
Description
Technical field
The utility model relates to the composite pipe field, particularly a kind of plastic composite pipe.
Background technique
The lining plastic composited pipe skin is the structural bearing layer, and internal layer is the high tenacity corrosion resistant thermoplastic plastic pipe, this composite pipe structure safety and energy-conserving and environment-protective.What generally adopt in the market is that the aluminum alloy lining is moulded or steel lining such as moulds at the metallic plastic-lining composite pipe, because the consumption of the metal tube material energy is all bigger, and the thermal expansion coefficient of metal and plastic materials differs bigger, when temperature fluctuation is big, can produce stratification, reduce the working life of composite pipe.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of heat resistant environmental-friendly, the plastic composite pipe that working strength is high.
The technical solution of the utility model: a kind of plastic composite pipe, include the outer tubing of chlorinated polynvinyl chloride (CPVC), be arranged on outside the described chlorinated polynvinyl chloride (CPVC) tubing in the atactic copolymerized polypropene in the tubing through cold drawn.
Further improvement of the utility model: the ratio of the thickness of tubing is 1 in the outer tubing of described chlorinated polynvinyl chloride (CPVC) and the described atactic copolymerized polypropene: 1.5-3.
Further improvement more of the present utility model: tubing interference fit in outer tubing of described chlorinated polynvinyl chloride (CPVC) and the described atactic copolymerized polypropene.
The beneficial effects of the utility model: adopt technique scheme, its thermal expansion coefficient of tubing is close in outer tubing of described chlorinated polynvinyl chloride (CPVC) and the described atactic copolymerized polypropene, even when temperature fluctuation is big, also stratification can not occur, its working strength height, the life-span is long; The outer tubing intensity height of wherein said chlorinated polynvinyl chloride (CPVC), good heat resistance, tubing health, nontoxic in the described atactic copolymerized polypropene, Security is good when carrying the hot water or cold water.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1, a kind of plastic composite pipe includes the outer tubing 1 of chlorinated polynvinyl chloride (CPVC), is arranged on outside the described chlorinated polynvinyl chloride (CPVC) tubing 2 in the atactic copolymerized polypropene in the tubing 1 through cold drawn.Wherein said cold drawn be routine techniques, because tubing 2 has certain elasticity in the outer tubing 1 of chlorinated polynvinyl chloride (CPVC), the atactic copolymerized polypropene, adding under the situation of pulling force, tubing in the atactic copolymerized polypropene 2 is directly being drawn in the outer tubing 1 of chlorinated polynvinyl chloride (CPVC) getting final product.
In the utility model specific embodiment, the ratio of the thickness of tubing 2 is 1 in the outer tubing 1 of described chlorinated polynvinyl chloride (CPVC) and the described atactic copolymerized polypropene: 1.5-3.By the plastic composite pipe of described thickness than manufacturing, its heat resistant environmental-friendly, working strength is better.
In the utility model specific embodiment, outer tubing 1 of described chlorinated polynvinyl chloride (CPVC) and interior tubing 2 interference fit of described atactic copolymerized polypropene.Interference fit is set, can be so that the connection of described plastic composite pipe be compacter, performance is better.
Claims (3)
1. plastic composite pipe is characterized in that: include the outer tubing of chlorinated polynvinyl chloride (CPVC), be arranged on outside the described chlorinated polynvinyl chloride (CPVC) tubing in the atactic copolymerized polypropene in the tubing through cold drawn.
