Abstract
The utility model discloses a plastic aluminium abutting joint welded composite tubular product, which is composed of plastic aluminium composite tubes, wherein, each plastic aluminium composite tube is composed of a plastic inner tube and a plastic outer layer; an abutting joint welded aluminium tube layer is arranged between the plastic inner tube and the plastic outer layer; an inner stickiness layer is arranged between the plastic inner tube and the abutting joint welded aluminium tube layer; an outer stickiness layer is arranged between the plastic outer layer and the abutting joint welded aluminium tube layer. The outside diameter of the thickness of the inner tube achieves the requirement of intendedsize of a full plastic tube. The plastic aluminium abutting joint welded composite tubular product is adequate for water supply and heating tubes, gas tubes, air-condition cooling plate conduits, etc.
Description
Technical field
The utility model relates to a kind of plastic-al pipe material, especially relates to a kind of aluminium butt welding composite pipe of moulding.
Background technique
Along with the expansion of the employed scope of pipeline, the environment of use also becomes increasingly complex, and the The selection of pipe of transporting system receives more concern day by day, so just tubing is had higher requirement.Existing tubing mostly is plastic-aluminum pipe and overall plastic pipe, and these two kinds of tubing can not be used for two or more purposes respectively simultaneously, are used for feedwater as overall plastic pipe, and plastic-al pipe is used for heating, on with material, must use two class pipe fittings, bring certain degree of difficulty so just for the buying installation.
Summary of the invention
The purpose of this utility model is can not be used for simultaneously at aforementioned tubes the defective of two or more purposes, provide a kind of on performance, can reach two or more purposes mould aluminium butt welding composite pipe.
In order to achieve the above object, the utility model has mainly adopted following technological scheme to realize.The utility model mainly is made up of aluminium plastic composited tube, described aluminium plastic composited tube is made up of plastic inner pipe and plastic outer layer, between plastic inner pipe and plastic outer layer, be provided with the butt welding aluminum tube layer, on the butt welding aluminum tube layer, be provided with weld seam, between plastic inner pipe and butt welding aluminum tube layer, be provided with interior adhesive layer, adhesive layer outside between plastic outer layer and butt welding aluminum tube layer, being provided with.The external diameter of tube thickness reaches the requirement of overall plastic pipe nominal size in described.
The utility model compared with prior art has following tangible advantage and innovation.(1) the utility model is different from PP-R stable state pipe, it be with the aluminium strip stitching thread with the butt joint pattern by welding together, and PP-R stable state pipe is to stick together with the hot melt adhesive overlap joint, thereby improved the intensity of aluminum pipe, and the composite pipe that this tubing is made up of polyethylene or poly-third material layer and metallic aluminium, it organically combines plastics and metallic aluminium, has the pliability of plastic tube and the rigidity of metal tube simultaneously concurrently, and has avoided shortcoming separately.(2) the utility model combines the advantage of plastic tube, combine simultaneously the advantage of butt joint wlding again, aspect long term strength, have overall plastic feature and metallicity, the mechanical relaxation that suppresses high polymer there is certain effect, to the ability enhancing of long-term or degree and creep rupture.(3) the utility model supporting PP-R of energy or PE-RT pipe fitting adopt hot melt to connect, and have changed the Placement of butt joint tubing copper fitting, and be safe and reliable, Never-leakage.Because mesosphere aluminium strip joint close is butt joint, therefore it promptly has the stabilizing mechanical performance of plastic aluminum steady-state tube, solve the bonding problem of stable state pipe overlapping the slot simultaneously, make domain of the noisy formation of aluminium, pipe ring and radial pull have been improved, simultaneously also reduced vertical relaxation shrinkage, made tubing thermal cycle pressure test be higher than the overall plastic pipe of butt welding plastic-aluminum stationary.(4) coefficient of linear expansion is little, and axial deformation is little.The utlity model has the intensity suitable with metal pipe, good toughness can increase the stability of pipe network system operation, can reduce simultaneously to be used to compensate tubing and to be out of shape all pipe ranges and free wall quantity, in use can improve a grade and use the economical with materials cost.(5) high temperature resistant, high pressure.Under its continuous operation pressure of length of regulation, the line transportation water temperature can reach 95 ℃.(6) easy installation and reliable.The employing hot melt connects, and need not mantle fiber, and the several seconds can be finished a joint and be connected, and is connected with metal tube and water knockout drum and adopts the high-quality copper insert, and is safe and reliable, long service life.
The utility model is applicable to water supply, heating pipe, also is applicable to uses such as gas pipe, heat sink of air conditioner pipeline.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model stereo dissected figure.
Embodiment
As shown in the figure, the utility model mainly is made up of aluminium plastic composited tube 1, described aluminium plastic composited tube 1 is made up of plastic inner pipe 2 and plastic outer layer 7, between plastic inner pipe 2 and plastic outer layer 7, be provided with butt welding aluminum tube layer 4, on the butt welding aluminum tube layer, be provided with weld seam 5, adhesive layer 3 between plastic inner pipe 2 and butt welding aluminum tube layer 4, being provided with, adhesive layer 6 outside between plastic outer layer 7 and butt welding aluminum tube layer 4, being provided with.
The external diameter of tube thickness reaches the requirement of overall plastic pipe nominal size in described.
The utility model is applicable to water supply, heating pipe, also is applicable to uses such as gas pipe, heat sink of air conditioner pipeline.
