The utility model has the advantages of good rigidity, beautiful appearance, corrosion resistance, light weight, low cost and superior performance. The utility model can be used on various pipes, handrails of stairway and bus, etc.

Description

Multiple layer metal and macromolecular material composite pipe

Technical field

The utility model relates to not having cutting substantially and using the plastics-production particular product of a kind of metal tube, especially can be used as various different-diameters, the multiple layer metal and the macromolecular material composite pipe of the pipeline of various different occasions and stair, bus handrail railing, interior decoration and Curtain rail etc.

Background technique

In the prior art, plastic stainless-steel composite-tubes all adopts drawing machine to be combined with each other with finished product Stainless Steel Tube and finished product plastic tube by a drawing cover.Not only manufacturing efficiency is low for it, and labor intensity is big, and wastes particularly stainless steel of raw material, and yield rate is low, the cost height.The applicant designs successfully and has obtained No. 99220392.9 Patent right " plastic stainless-steel composite-tubes " in May, 1999, though can solve existing questions in the prior art, but the insufficient strength of finding it in enforcement and using process is big, thereby its Applicable scope is subjected to certain restriction.

Summary of the invention

Low in order to overcome in the prior art existing manufacturing efficiency; the waste stainless steel; No. 99220392.9 existing intensity of patent of cost height, particularly the applicant are lower, the deficiency that application area is limited; the utility model provides a kind of various different occasions that can be used in; tubing intensity is big, and cost is low, and performance is good; inexpensive interior of light weight is the macromolecular material pipe, and be outer for carrying the multiple layer metal and the macromolecular material composite pipe of inner protective layer and outer protection decorative layer high duty metal composite pipe.

The technological scheme that its technical problem that solves the utility model adopts is: carry out substance transformation on the basis of No. 99220392.9 patents of the applicant; emphasis is that the stainless steel outer tube with individual layer changes into by placed in the middle and is high duty metal basic unit; one side is an inner protective layer, and another side docks the thin-wall circular tube that is welded for the multilayer metal compound band of outer protection decorative layer.Be that multiple layer metal described in the utility model and macromolecular material composite pipe are by interior pipe 2 and outer tube and the two is cohered the glue layer 3 that becomes one constitute; it is characterized in that this composite pipe; its above-mentioned interior pipe 2 is the macromolecular material pipe, above-mentioned outer tube then by high duty metal basic unit 1 placed in the middle and with its inside and outside the compound inner protective layer that becomes one 4 and outer protection decorative layer 5 form.

Above-mentioned outer tube is served as reasons and is docked the thin-wall circular tube that is welded for high duty metal basic unit 1 with the composite strip of its compound metal matter inner protective layer that becomes one 4 and outer protection decorative layer 5 between two parties.

The beneficial effects of the utility model are: outer tube itself be exactly in, in, the composite pipe of outer three layers of different metal, it combines with the macromolecular material pipe again, its each layer just can Each performs its own functions, reaches best of breed, forms existing favorable rigidity (realizing by 1), withstand corrosion and convection cell resistance little (realizing by 2) again, simultaneously attractive in appearance again, application area is wider, can be used for various different occasions, and light weight is inexpensive, and performance is very superior.

Description of drawings

Further describe as follows below in conjunction with accompanying drawing and most preferred embodiment to structure characteristic of the present utility model: accompanying drawing is that one of the utility model most preferred embodiment is perpendicular to the cross-sectional cross-sectional configuration schematic representation of the axis of pipe.

The high duty metal basic unit of 1 outer tube among the figure, pipe in the 2 macromolecular material matter, 3 cohere the glue layer that becomes one, the inner protective layer of 4 outer tubes, the outer protection decorative layer of 5 outer tubes with inside and outside two pipes.

Embodiment

Extrude with plastic extruder and in the PE of sizing, cooling, traction, oven dry matter macromolecular material pipe 2 outer surface be coated with one deck macromolecule binder 3, and then compound be the outer tube that the band butt joint of stainless steel inner protective layer 4 below the 0.1mm and outer protection decorative layer 5 is welded by all compound layer thickness of carbon steel matter basic unit 1 and two sides.

Change as present embodiment:

1, the composite surface material of basic unit's carbon steel, promptly inside and outside protection decorative layer can be used metallic material such as metal titanium, aluminium, red copper, brass according to different needs instead;

2, the interior pipe of macromolecular material also can be used replacements such as PE, PVC fluorine plastic tube as required.

Claims (3)

1, a kind of multiple layer metal and macromolecular material composite pipe; constitute by interior pipe and outer tube and with the bonding agent layer that the two gluing becomes one; it is characterized in that this composite pipe; pipe was for the macromolecular material pipe in it was above-mentioned, and above-mentioned outer tube then is made up of with compound inner protective layer that becomes one inside and outside it and the outer decorative layer of protecting high duty metal basic unit placed in the middle.

2, multiple layer metal according to claim 1 and macromolecular material composite pipe is characterized in that described outer tube can be thin-wall circular tube.

3, multiple layer metal according to claim 2 and macromolecular material composite pipe is characterized in that described thin-wall circular tube can be the composite strip that butt welding is connected into.
