Product Introduction

F-PPR high-performance fiberglass composite pipe has a three-layer structure, with PP-R material on the inner and outer layers, and fiberglass reinforced composite material on the middle layer. The PP-R material in the inner layer ensures the sanitary performance of the pipe, the middle layer realizes the effect of strengthening the pipe and reducing the linear expansion coefficient, and the outer layer PP-R is convenient for hot melt socket connection with traditional PP-R pipe fittings. By combining three layers, a reliable water supply pipeline system is formed. This new type of pipeline has the "three highs and one low" characteristics of high strength, high toughness, high stiffness, and low linear expansion coefficient, which makes up for the limitations of ordinary PP-R pipe risers, exposed pipes, and hot water pipes. It is an ideal improvement and beneficial supplement to PP-R pipeline. Execution standard: CJ/T258-2007

Product Features

1. Low coefficient of linear expansion, andAluminum-plastic composite pipeApproaching and completely solving the problem of plastic pipe expansion and contraction.

2. The pipe has high rigidity, good dimensional stability, and will not sag due to its own weight during external installation, making it straight and beautiful.

3. The static pressure resistance strength is significantly improved. Under the same usage conditions, composite pipes of the same specifications can withstand pressure loads that are more than 25% higher than ordinary PP-R, improving the safety factor of the pipeline system.

4. Good toughness and excellent low-temperature impact resistance.

5. High temperature resistance, can be used for a long time at temperatures below 90 ℃ under appropriate pressure, and is more suitable for use as a hot water pipeline.

6. Ordinary PP-R hot melt socket fittings can be used for connection, with complete accessories and convenient and reliable construction.

7. Inheriting the excellent smoothness and hygiene performance of PP-R pipes, it can be safely used as a water supply system.

scope of application

1. Water supply system for civil buildings

2. Pipe network for air conditioning equipment

3. Industrial water systems such as purified water, beverages, and dairy products

4. Chemical and petrochemical industries, such as pipeline networks for transporting various types of corrosive liquids

5. Pipeline network for solar energy facilities

6. Factory compressed air pipeline network

7. Surface mounted pipe

Installation steps

1. Cutting: When cutting pipes, the end face must be perpendicular to the pipe axis. Pipe cutting generally uses pipe cutters or pipe cutting machines, and sharp steel saws can be used if necessary, but the cut surface of the pipe should be free of burrs and edges.

2. Cleaning: Use a clean cloth to clean the welding parts of pipes and fittings (recommended to wipe with alcohol), and the connecting end faces of pipes and fittings must be clean, dry, and free of oil stains.

3. Marking: Mark the pipe according to the welding depth specified in Table 1:

4. Heating: After the hot melt machine heats up, insert the pipe and fittings into the hot melt mold head without rotation. Stop when the pipe reaches the marking position:

5. Welding: After reaching the heating time, the pipe and fittings are pulled out without rotation, and the pipe is inserted into the fitting socket without rotation, and left to cool for a certain period of time.

Note:

Hot melt connection should be used between water supply polypropylene pipes and pipe fittings of the same material, and special hot melt tools should be used for installation. Emphasis should be placed on concealed walls, and pipes within the floor surface must be connected using hot melt instead of threaded or flanged connections.

The connection between water supply polypropylene pipes and metal fittings should use polypropylene fittings with metal inserts as a transition. The fittings should be hot-melt connected to plastic pipes and threaded to metal fittings or sanitary ware hardware accessories. In addition, when connecting valves, faucets, and metal fittings, elbows and tees should be equipped with fixed supports and firmly fixed on the wall.

Suppression steps

1. The test pressure shall be 1.5 times the working pressure of the pipeline system, but not less than 0.6Mpa

2. For PP-R pipeline systems, water pipe testing is generally required to be conducted 24 hours after the installation of pipeline connections

3. Before the water pipe pressure test, safe and effective fixing and protection measures should be taken for the pipeline, but the joints should be exposed

4. Water pressure test steps

(1) Seal the end of the pressure test pipeline, slowly inject water, and simultaneously remove the gas inside the pipeline

(2) After filling with water, conduct a water tightness check

(3) It is advisable to use a manual pump to slowly increase the pressure, and the pressure increase time should not be less than 10 minutes

(4) Raise the test pressure, stop applying pressure, stabilize for 1 hour, and observe if there is any water leakage at the joint

(5) Stabilize the pressure for one hour, add pressure to the test pressure value, and the pressure drop within 15 minutes should not exceed 0.05Mpa, which is qualified
