Abstract

The utility model discloses a steel and plastic composite pipe. The utility model is provided with a steel pipe layer, and a plastic pipe layer is lined in the steel pipe layer; an adhesive layer is arranged between the steel pipe layer and the plastic pipe layer. The utility model has the characteristics of reasonable structure, good firmness and shock resistance, sanitation, innocuity, bacteriostasis, antisepsis, corrosion resistance, long service life, etc.

Description

Novel steel-plastic composite pipe
Technical field:
The utility model relates to a kind of water pipe.
Background technique:
21st century is the epoch of scientific and technical develop rapidly, it is the brilliant epoch of continuing continuity of human civilization science and technology, and China is along with fast development economic and science and technology, and the social life level improves day by day, makes people more and more pay attention to environmental protection and healthy problem.Because the secondary pollution phenomenon of drinking water quality is comparatively serious at present, many town dwellers are very high to the expectation that obtains safe potable water, some flourishing urban areas of China simultaneously, quality classification water supply engineering and drinking-water engineering of registering one's residence also transfers large size to by the small size pilot and implements.In view of the situation, China's demand growth to the supply pipe of energy-conservation, safety, environmental protection, health at present is very fast.Galvanized iron conduit can cause the potable water secondary pollution because of there being the corrosion problem, and after the nineties in last century, it just withdraws from building pipe market gradually along with the appearance of other pipeline.But, common plastic water supply pipe is also fairly obvious in the deficiency of configuration aspects, water inlets such as PE-XP, PP-R, CPVC are aspect physical and mechanical properties such as rigidity, intensity, toughness and creep resistance, with respect to steel pipe all is weak property, under condition aspect the bright dress, any external attack all can make pipeline be destroyed in moment easily, can't satisfy long-term application target.And pure Stainless Steel Tube also has the shortcoming of its bad processing, as inner wall coarse, transporting resistance is big, energy consumption is high, easy fouling, can breed bacteria and microorganism, and stainless steel easily separate out heavy metal also can polluted water, thereby water quality secondary treatment cost is improved.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, as the good novel steel-plastic composite pipe of water pipe using effect.
Technical solution of the present utility model is:
A kind of novel steel-plastic composite pipe is characterized in that: the steel pipe layer is arranged, be lined with plastic pipe layer in the steel pipe layer, between steel pipe layer and plastic pipe layer adhesives layer is set.
The thickness of plastic pipe layer is 1/2~1/3 of steel pipe layer thickness.Plastic pipe layer adopts the PE-RT plastics.
The utility model is rational in infrastructure, and fastness, good impact resistance have simultaneously that health is nontoxic, a bacteriostasis antibiosis, characteristics such as corrosion-resistant, long service life.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of novel steel-plastic composite pipe has steel pipe layer 1, is lined with plastic pipe layer 2 in the steel pipe layer 1, between steel pipe layer 1 and plastic pipe layer 2 adhesives layer 3 is set.The thickness of plastic pipe layer 2 is 1/2~1/3 of steel pipe layer 1 thickness.Plastic pipe layer 2 adopts the PE-RT plastics.It is the low cohesive force adhesive of main body base-material that binder adopts vinyl resin.

Claims (3)
