Product Introduction

PP-RPlastic aluminum steady-state tubeIt is the preferred pipe material for hot water, high-temperature radiator heating, and central air conditioning fields. The pipe is made by adding alloy aluminum on the basis of PP-R water supply pipe, and compounding PP-R pipe and alloy aluminum at high temperature through polymer adhesive. It combines the advantages of plastic and metal pipes, while also possessing the hygiene, sealing, and rigidity of plastic pipes and metal pipes. It has higher strength and more stable mechanical properties, as well as UV protection function. Its linear expansion coefficient is 1/5 of ordinary PP-R pipes, close to metal pipes, and has higher stability and safety. Execution standard: CJ/T210-2005

Product Features

1. Linear expansion coefficient reductionThere is no significant thermal expansion or contraction during pipeline installation and use. In the fields of high-temperature hot water and HVAC, outdoor exposed pipelines have obvious advantages in application.

2. Superior oxygen barrier performance, hygiene performance, and excellent UV resistance

Due to the intermediate layer of the pipeline being an alloy aluminum layer.

3. Eliminate oxidation, completely isolate external air, keep the water flow medium in the pipeline system from oxygen infiltration, suppress bacterial growth inside the pipe, and ensure the hygiene performance of the pipe.

4. High static pressure resistance and good temperature resistance5. The hot melt socket connection method is safe, reliable, and convenient (before connection, use a dedicated peeler to evenly peel off the outermost two layers, inner tube, and...)PPR pipe fittings

Hot melt).

6. The pipe material is detectable, which brings convenience to later construction (the presence of metal layers in the pipeline is easily detectable).

scope of application

1. Central air conditioning duct

2. Radiator connecting pipeline

3. Heating pipeline renovation

4. Indoor hot and cold water pipelines

5. Surface or outdoor installation of pipelines

6. Pipelines that need to block oxygen and pollutants

Precautions

1. PP-R pipes have lower hardness and lower rigidity than metal pipes, and should be protected during transportation and construction to avoid mechanical damage caused by inappropriate external forces. After concealed installation, the position of the pipeline should be marked to prevent secondary decoration from damaging the pipeline.

2. PP-R pipes have a certain degree of low-temperature brittleness below 5 ℃. Be careful during winter construction and use sharp cutting tools to slowly cut the pipes. The installed pipelines should not be subjected to heavy pressure or knocking, and if necessary, protective covers should be placed on areas that are susceptible to external forces.

3. PP-R pipes are prone to aging and degradation under long-term exposure to ultraviolet radiation, and must be wrapped with a dark protective layer when installed outdoors or in direct sunlight.

4. Except for using mechanical connection methods such as threaded inserts or flanges to connect PP-R pipes with metal pipes or water dispensers, all others should be connected by hot melt to integrate the pipes without any leakage points.

5. The coefficient of linear expansion of PP-R pipes is relatively high (0.15mm/m ℃), and technical measures must be taken to prevent pipeline expansion and deformation when laying pipes openly or indirectly.

6. After pipeline installation, pressure testing must be conducted before sealing (direct burial) and covering the decorative layer (non direct burial concealed laying). The pressure test of the cold water pipe shall be 1.5 times the working pressure of the system, but not less than 1MPa; The test pressure for hot water pipes shall be twice the working pressure, but not less than 1.5MPa. Technical regulations for pressure testing time and methods.

Installation steps

1) Cut the pipe and clean the port: Use a dedicated cutting machine to cut the pipe according to the construction size, and use a dedicated filing knife or dedicated deburring device to remove burrs on the cutting surface.2) Rolling the pipe: Push the pipe into the rolling hole of the rolling cutter for rolling, and the end face of the pipe should be in contact with the top of the inner hole of the rolling cutter. There should be uniform aluminum shavings in the discharge groove of the rolling cutter until the aluminum layer at the fusion joint is completely removed.3) Heating of pipes and fittings: Insert pipes and fittings into P-R simultaneously without rotation

Plastic aluminum steady-state tube

Heating is carried out in a dedicated mold head.
