Abstract
The utility model provides a plastic pipe which is used for the drinking water conveyance or the sewage drainage. The plastic pipe is characterized in that the wall of the plastic pipe has a three-layered structure made of different materials. The utility model has the advantages of low cost, high strength, good toughness and wide use range.
Description
The utility model relates to a kind of drinking-water and carries or the used plastic pipe of sewerage draining.
Water delivery, the draining pipe that uses all is the monolayer plastic pipe at present, and this pipe is because the material that uses is single, and its cost of material is higher, if use the reworked material manufacturing, though cost is low, pipe intensity is poor again, and pipe purposes narrow limitation is bigger.
The utility model purpose provides a kind of plastic pipe that can overcome the deficiency of above plastic pipe.
Technology of the present utility model is achieved in that the plastic pipe tube wall is by the three-decker outer, that interlayer and internal layer constituted.
Adopt the plastic pipe of above structure, its good effect is, the tube wall interlayer can be with reworked material with low cost or other, and outer and internal layer is selected virgin material for use according to purposes, thereby can effectively reduce cost, increase pipe intensity and toughness, and its purposes is also more extensive.
Further specify embodiment below with reference to the accompanying drawings:
Fig. 1 is the plastic pipe sectional view.
As shown in Figure 1, plastic pipe is by skin 1, and interlayer 2 and internal layer 3 constitute, and select for use different raw material to place co-extrusion head feeding end according to the purposes of pipe, by head extruding and moulding simultaneously.If pipe is used for the sewerage draining, pipe skin 1 can be used virgin material, and interlayer 2 and internal layer 3 can be with reworked material or other; If pipe is used to the delivery pipe of drinking water, interlayer 2 can be used reworked material, and skin 1 and internal layer 3 are used virgin material, internal layer 3 virgin material polythene, and each layer color tunable joined.
Claims (1)
1, a kind of plastic pipe is characterized in that: the three-decker that tube wall is made up of outer (1) interlayer (2) and internal layer (3).
