Abstract

The utility model provides a novel polypropylene (PPR) plastic aluminum steady-state pipe. The PPR plastic aluminum steady-state pipe is arranged in a middle layer of a pipe and plays roles in insulating permeation of gas such as air, resisting ultraviolet rays, reducing linear expansion and improving strength and safety performance of the pipe. Meanwhile, due to the fact that the aluminum layer is in the middle of the pipe, when connected with an accessory, the pipe can be directly welded with the accessory, and the aluminum layer does not need coiling and cutting to be welded just like an aluminum layer in a traditional PPR plastic aluminum steady-state pipe, and therefore production efficiency is greatly improved, and welding quality is ensured.

Description

A kind of novel PP-R plastic-aluminum stationary pipe

Technical field

The utility model relates to the tubing technical field, particularly relates to a kind of novel PP-R plastic-aluminum stationary pipe.

Background technique

The aluminium lamination of traditional PP-R plastic aluminum steady-state tube is on the top layer that is coated on tubing; outermost one deck is very thin protective layer PP-R layer 1, as shown in Figure 2, wherein in the middle of aluminium lamination 3 arrange comparatively near PP-R layer 1; with in accessory is connected; after the aluminium lamination on surface volume need to being cut could with the accessory welding, this process is had relatively high expectations; if the process control that volume is cut is bad; be easy to occur seepage, and it is large to involve in the process labor intensity of cutting, so that the installation efficiency that pipe-line system connects is low.Because the protective layer of aluminium lamination external layer is thinner, in actual use, the foaming bulge phenomenon often occurs, so that aluminium lamination has lost actual protective action.

The model utility content

In order to overcome the deficiencies in the prior art, technical purpose of the present utility model provides a kind of novel PP-R plastic-aluminum stationary pipe that line expands and improves the effect of tubing Strength Safety that reduces.

For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:

A kind of novel PP-R plastic-aluminum stationary pipe, described PP-R plastic-aluminum stationary tubing main body successively ecto-entad comprise PP-R skin, outer glue-line, middle aluminium lamination, inner glue layer and inner tube, aluminium lamination is arranged on the centre of tubing wall in the middle of wherein said, and is equal or close from the distance of outer pipe wall and inwall.

Preferably, in the middle of described aluminium lamination apart from pipe material inner wall be the total wall thickness of tubing 1/5 to 1/2 between.

Preferably, in the middle of described aluminium lamination apart from outer pipe wall be the total wall thickness of tubing 1/5 to 1/2 between.

Compared with prior art, the utility model has the advantage of:

Simple in structure, beautiful shape is generous, easy for installation.Reduce the welding operation that tubing is connected with accessory, improve installation efficiency.Tubing can carry out inside and outside layer hot melt with accessory and be connected, and has stopped aluminium lamination and has been subjected to external influence, has improved product working life.Tubing and accessory Placement are taked inside and outside layer double heat staking connection, have strengthened heat seal strength, have guaranteed the quality of interface.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only is used for explaining model utility, and be not used in the restriction model utility.

As shown in Figure 1, the utility model provides a kind of novel PP-R plastic-aluminum stationary pipe, described PP-R plastic-aluminum stationary tubing main body successively ecto-entad comprise PP-R skin 1, outer glue-line 2, middle aluminium lamination 3, inner glue layer 4 and inner tube 5, wherein, middle aluminium lamination 3 is arranged on the centre of the tube wall of tubing, makes middle aluminium lamination 3 away from the outer wall of tubing;

As shown in Figure 3, the outer wall of middle aluminium lamination 3 and tubing is close with the distance of inwall, particularly in the middle of aluminium lamination 3 apart from pipe material inner wall, outer wall apart from r, r ₁Scope be the total wall thickness e of tubing 1/5 to 1/2 between, i.e. r=(1/5-1/2) e, r ₁=(1/5-1/2) e.

The aluminium lamination of the novel PP-R steady state pipe that the utility model provides designs at tubing in the mesosphere, play the gas permeations such as secluding air, uvioresistant, the effect that reduces the line expansion and improve the tubing Strength Safety, simultaneously, because aluminium lamination is in the centre of tubing, then when being connected with accessory, can be directly and accessory carry out welding, do not need as traditional PP-R plastic aluminum steady-state tube, volume is cut again welding behind the aluminium lamination, greatly improved manufacturing efficiency, and guaranteed to the welding quality.

Wherein, the PP-R plastic aluminum steady-state tube that provides of the utility model can carry out inside and outside footpath hot melt with accessory and is connected.

As shown in Figure 4, concrete novel PP-R plastic-aluminum stationary pipe 7 when mounted, first with the inside and outside wall heating of sweat soldering equipment with the PP-R plastic aluminum steady-state tube, the bellmouth of accessory 6 is simultaneously heating also, after being heated to the scheduled time, quick and stable and equably novel PP-R plastic-aluminum stationary pipe 7 is pushed into accessory 6 bellmouths, be cooled to the stipulated time after, then finish connection.
