PPR steady state tube, aluminum plastic PPR steady state tube
Product performance:
PPR aluminum plastic steady - state tube combines the advantages of PP - R tube and metal tube, and has the hygienic, sealing and rigidity of PP - R tube metal tube, forming unique characteristics. It is superior to general plastic tubes and has excellent physical properties such as small linear expansion coefficient, no oxygen permeability, UV resistance, high strength and high temperature resistance.
1. The coefficient of linear expansion is small: the linear expansion coefficient of the PPR aluminum - plastic steady - state tube is 1/5 of that of the ordinary PP - R tube, which is close to the metal tube, and the tube has no significant change in thermal expansion and contraction. During the installation of the project, it is not necessary to consider the deformation of open - ended pipelines with a horizontal installation length of less than 40 m. In high temperature hot water, HVAC and outdoor wall - mounted pipeline applications, the advantages are obvious.
Practice has proved that PPR aluminum plastic steady - state tube has no deformation or abnormal phenomenon after long - term cold - heat cycle test, which fully demonstrates that PPR aluminum - plastic steady - state tube has stable high temperature resistance.
2, non - permeable, sanitary: due to the PPR aluminum plastic steady - state tube covered with alloy aluminum foil on the outer surface of the PP - R inner tube, the plastic is "punched" with a layer of metal armor, completely isolating the outside air, maintaining the pipeline system. The internal fluid medium is not infiltrated by oxygen and injects light, thereby inhibiting the growth of algae bacteria and ensuring water quality. PPR aluminum plastic steady - state tubes are used to prevent oxidation and corrosion of metal equipment when used in central air conditioning systems and heating systems.
3, anti - ultraviolet: PPR aluminum plastic steady - state outer aluminum layer, covered with a layer of PP - R protective layer. The aluminum layer effectively blocks ultraviolet light. PP - R protects the aluminum layer from oxidation, effectively absorbs and shields UV rays, and provides a UV protection barrier for the tube. This pipe can be used for both outdoor and surface mount pipes. It does not require UV protection and has a longer life. It is ideal for outdoor building solar and thermal systems.
4, high compressive strength, good temperature resistance: compared with other pipes, PPR aluminum plastic steady - state tube has good pressure bearing performance, and has certain metal characteristics in terms of long - term strength. A pipe was added due to the addition of a metal layer. The rigidity reduces the creep of the pipe, thereby increasing the compressive strength and temperature resistance of the pipe. In maintenance inspection, the metal aluminum detector can easily detect the direction of the pipe and damage the leak point. Pipe and fittings model: DN15 - 20 - 25 - 32 - 40 - 50 - 65 - 80 - 100
