Abstract
The invention discloses a composite type plastic pipe comprising a stainless steel layer, wherein a strengthening irregular copolymerization polypropylene pipe layer is arranged on the outer wall of the stainless steel layer, a chlorinated polyethylene pipe layer is arranged on the outer wall of the irregular copolymerization polypropylene pipe layer, the three layers are pressed together to form an integration. Because the inner, intermediate and outer layers of different anticorrosive materials have better acid-resistant and alkali-resistant corrosion property, moisture resistance and oxidation resistance, the life of the composite type plastic pipe is greatly prolonged. The composite type plastic pipe has the advantages of convenience for manufacture, high safety property and broad use range.
Description
Technical field
The present invention relates to the composite pipe field, especially a kind of composite plastic pipe.
Background technique
Steel pipe is carried and is extensively applied to industrial fields such as chemical industry, pharmacy and transportation, but steel pipe itself is vulnerable to pH value atmosphere and the corrosion of external factor such as external humidification and electrochemistry and the influence of pipeline self internal factor of chemical industry factory.Pipeline is prone to cause seepage, influences ordinary production and uses.Method commonly used uses metal protective film that pipeline is reinforced, but metal protective film is vulnerable to soda acid, electrochemical corrosion, and energy consumption is big, and cost is also higher.Simple practical stainless steel pipeline, raw material are somewhat expensive, and cost is high.Therefore the employing plastic steel composite pipe is also arranged, but the tensile strength of plastics is not high, Young's modulus is low, and outer layer plastic tube is can not synchronous reaction stressed when steel pipe receives active force, and reinforcement effect is relatively poor.
Summary of the invention
The technical problem that the present invention mainly solves provides lower, anticorrosive strong, the heat resistant environmental-friendly of a kind of cost, composite plastic pipe that working strength is high.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of composite plastic pipe is provided; Comprise stainless steel lining; Outer wall setting at stainless steel lining plays humidification polypropylene random copolymer pipe layer, is provided with haloflex pipe layer at the outer wall of polypropylene random copolymer pipe layer, and three layers are pressed into an integral body jointly.
In preferred embodiment of the present invention, the cross section of described composite plastic pipe is circular.
In preferred embodiment of the present invention, the ratio of the thickness of stainless steel lining, polypropylene random copolymer pipe layer and haloflex pipe layer is 1:1.5-2:1 in the described composite plastic pipe.
The invention has the beneficial effects as follows: three layers of different corrosion-resistant material in China and foreign countries in the present invention has, have acid-alkali-corrosive-resisting and humidity and oxidation resistance preferably, prolonged the life-span of plastic tube greatly.Easy to make, Safety performance is high, and using scope is extensive.
Description of drawings
Fig. 1 is the perspective view of a kind of composite plastic pipe one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, stainless steel lining; 2, polypropylene random copolymer pipe layer, 3, haloflex pipe layer.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1; A kind of composite plastic pipe comprises stainless steel lining 1, plays humidification polypropylene random copolymer pipe layer 2 in the outer wall setting of stainless steel lining; Be provided with 3, three layers on haloflex pipe layer at the outer wall of polypropylene random copolymer pipe layer and be pressed into an integral body jointly.
Wherein, the cross section of described composite plastic pipe is circular.
The ratio of the thickness of stainless steel lining 1, polypropylene random copolymer pipe layer 2 and haloflex pipe layer 3 is 1:1.5-2:1 in the described composite plastic pipe, and is better than anticorrosive strong, the heat resistant environmental-friendly of the composite plastic pipe of making, working strength by said thickness.
The three layers of different corrosion-resistant material in China and foreign countries had acid-alkali-corrosive-resisting and humidity and oxidation resistance preferably in the present invention had, and had prolonged the life-span of plastic tube greatly.Easy to make, Safety performance is high, and using scope is extensive.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
