I.Product introduction of Ginde Rigid PP-R plastic-aluminum stationary pipe 
Properties of Ginde Rigid PP-R plastic-aluminum stationary pipe 
The composted tube is ordinarily means the multilayer tube which is constituent of two layers or more thermoplastics and one layer embedding metallic layer. The rigidity over steady PP-R tube is a new style environmental building materials which is developed by our company, with a composite tube component of PP-R layer and aluminum layer, the rigidity over steady PP-R tube hitch together the PP-R plastics and the metal of aluminum organically, and at the same time, it also have the feature of flexible of the plastics tube and the rigidity of the metal tube, and it also ward off the most disadvantage . Through the integrative composite construction it achieve the stabilizing mechanical features, and be provided with a higher intensity and a better resistance to high temperature, it is a product to  replace the older generation (or products) by new ones for the traditional galvanize tube and the pure plastics tubes. The performance and feature of this tube is agree with the service condition of the centering air-conditioning, the transportation of the drinking water, and the project of heating and so on, so that, it is being accepted by more and more designers, consumers and construction units.
The composition: the Ginde rigidity over steady PP-R tube is constituent of five layers, the intermediate layer is aluminum, both  inner and outter layer is PP-R, and between the layers adopt the hot-melt adhesive which can be welded with both the plastics and the metal, which is piled out by means of high temperature and high pressure, this five layers is compounded multiply and organically; in the high molecular material, the PP-R is generally recognized that it have the superior features such as stable quality, clean and innocuity, odorless, corrosion resisting, light, high mechanical strength, good thermal endurance, not fouling, and long service life(it is generally recognized by international that not less than fifty years).

2.Major technical indicators of Ginde Rigid PP-R plastic-aluminum stationary pipe
1.Healthy and innocuity: this product belongs to environmental building materials, it can be used in the pipeline system of pure water and drinking water.
2.Due to the layer of aluminum in the middle, the coefficient of linear expansion is small, as well as the axial distortion, and it's strength is correspondent with the metal pipe, the tenacity is also good. Which can not only enhance the stability of the running of pipe network system, but also reduce the amount of pipe clips and freedom arms at the same time which are used to compensate the distortion of the pipes, save the materials costs.
3.Corrosion resisting and not fouling: which can ward off the worry of the pipeline fouling and blockage the laver, bathtub and the worry of yellow spot and rust.
4.High temperature ,and high pressure resisting: with the stated long time consecutive working pressure the temperature of the water transported in the pipeline can be *5 centigrade degrees.
5.Heat preservation and save energy: the coefficient of thermal conductivity is only 0.5 percent of the metal pipeline, the effect is very well when it is used as the heat preservation of the hot water pipeline.
6.The weight is light: it's specific gravity is only one seventh of the metal pipeline
7.The external form is beautiful: the inside and outside walls of this products is smooth, the fluid drag force is small, the color and luster is meekness, and the moulding is beautiful.
8.Can be buried: the location of the pipeline can be detected by the metal detector.
9.The installation is convenient and reliable: adopt the hot melt connection, not have to set screw, a joint connection can be finished in few seconds, the connection with the metal pipe and water separator adopt high quality copper embed component, safe and reliable.
*0.Long life span: Under the normal working condition ,the life span of the pipeline system can be more than fifty years.
*1.The probability to seep oxygen is zero: the alloy aluminum layer can obstruct the soaking in of the oxygen, effectively lighten the Oxidation corrosion of the radiating fins, boiler and other metal parts of appliance, and at the same time lighten the tube plug which are caused by this season, make the heating efficiency of the system is high.

3.Special patented products of Ginde Rigid PP-R plastic-aluminum stationary pipe

The connection between the metal rigidity over steady PP-R pipes and the matched PP-R pipe fitting adopts the method of hot melt. Do shuck off the cover of PP-R and aluminum band layer by the use of tools for specific production before the connection, and wipe off clean. The extrinsic feature of the PP-R pipe fitting is designed on the base of refer to the famous brands of external and combined with the culture feature of China by the profession industrial designer of our company, which have the feature of concision and elegance, Beautiful and face in good taste . Feature of the product
