Abstract
The utility model relates to a composite tube, which is characterized in that the inner part of a tube body is compounded with a PVC plastic layer. The outer surface of the tube body is coated with a polyethylene plastic layer, and an air isolation cavity is formed between the polyethylene plastic layer and the outer surface of the tube body. The utility model overcomes the defects that a red copper composite tube is easily oxidized and the cost is high, an aluminum plastic composite tube is easily worn, the compression resistance property is poor, the water flow is small, the pressure resistance is low, etc. The utility model has the advantages of simple structure, good shock resistance performance, strong corrosion resistance and long service life.
Description
The utility model relates to a kind of composite pipe.
Common water pipe all adopts galvanized pipe, nation-building portion make the forbidding galvanized pipe decision after, occurred red copper mould again the pipe and two kinds of alternatives of aluminium-plastic composite pipe.The easy oxidation pig copper of red copper composite pipe chlorine, thus unhygienic, and also cost is higher, and the user is difficult for accepting.That aluminium-plastic composite pipe then exists is easily aging, easy to wear, crushing resistance is poor, and water flow is little, and compression resistance is low, defectives such as thermal insulation property difference.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thus provide a kind of simple in structure, corrosion resistance is strong, good heat insulating, the composite pipe that crushing resistance is strong.
Technical solution of the present utility model is to be compounded with the PVC plastic layer at inboard wall of tube body, and pipe is stopped outer surface and coated the polyvinyl plastics layer.
Further design of the present utility model is to form the air insulated chamber between body and polyvinyl plastics layer.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, body 1 of the present utility model adopts Stainless Steel Tube 3, is compounded with PVC plastic layer 2 at body 1 inwall, and the outer surface of body 1 coats polyvinyl plastics layer 3, forms air insulated chamber 4 simultaneously between polyvinyl plastics layer 3 and the body 1, plays the insulation buffer action.Preparation process of the present utility model is: with health level 304 stainless steel band plates, be connected into slim body 1 through highfrequency welding, after eddy current testing detects, the polishing typing, even, the high-intensity sanitary grade PVC plastic layer 2 of extruding one layer thickness in the Stainless Steel Tube tube chamber coats the health level polyvinyl plastics layer 3 that last layer has air insulated chamber 4 by multiple plastics machine at body 1 outer surface afterwards.
The utility model is by above-mentioned specific design, have simple in structure, discharge big, shock resistance Good, wear-resisting, corrosion resistance is strong, the advantage of long service life.
Claims (2)
1, a kind of composite pipe is characterized in that being compounded with PVC plastic layer (2) at body (1) inwall, and body (1) outer surface coats polyvinyl plastics layer (3).
2, composite pipe according to claim 1 is characterized in that forming air insulated chamber (4) between body (1) and polyvinyl plastics layer (3).
