Product Introduction

PPRAluminum plastic alloy pipeIt is a high-strength specialized alloy aluminum strip butt welded (argon arc welded) aluminum tube as the substrate, with both the inner and outer composite materials made of PPR imported raw materialsAluminum-plastic composite pipeThe aluminum tube is bonded to PPR with high-performance hot melt adhesive and is formed by step-by-step co extrusion composite. The ASTM F1335 standard in the United States refers to aluminum-plastic composite pipes as "metal pipes with plastic protective layers".

Product Features

1. New welding technology: The composite pipes produced by our company use argon arc welding (laser welding) technology instead of traditional lap ultrasonic welding technology at the aluminum strip connection, which improves the strength of the aluminum strip connection and improves the pressure bearing performance of the product. The pressure bearing capacity is better than most products on the market, making it more suitable for use in high-pressure environments.

2. Higher quality standards: Our company produces composite pipes with aluminum strip thickness and inner and outer PPR thickness higher than industry standards to ensure higher strength and better quality, greatly improving the product's performance and service life.

3. Better rigidity: After the thickening of the aluminum strip layer and the inner and outer PPR layers, the rigidity of the pipe also increases, making it less prone to deformation and able to meet the requirements of exposed installation in various environments

4. New installation welding technology: The welding tool used in this product adopts a self-developed specialized welding equipment, which has obtained relevant national patents. This tool can completely eliminate direct contact between aluminum tubes and water during hot melt connection, solving the fatal defect of direct melt aluminum-plastic PP-R and fully ensuring the service life of the product.

5. Good oxygen resistance: The aluminum tube layer can completely isolate the penetration of oxygen and has 100% oxygen resistance. It can maintain a low oxygen environment in the heating system for a long time, effectively extending the service life of metal components such as boilers, radiators, water collectors, valves, etc., and reducing the user's usage and maintenance costs.

6. Good light shielding: With the natural light shielding properties of aluminum tubes, aluminum-plastic PP-R has excellent light resistance. To effectively resist the growth of algae and bacteria when the pipes are installed openly, thereby ensuring the hygiene and safety of water use.

scope of application

1. The preferred pipe material for various radiators and hot water heating pipelines.

2. The preferred pipeline for heating and water supply of independent household boilers (gas, natural gas, electric heating).

3. The preferred pipeline for household bathing hot water pipes, such as home solar energy, electric water heaters, and geothermal water.

4. Suitable for low-pressure fluid transportation in civil applications such as hot and cold water, direct drinking water, and air conditioning. It can also be used for low-pressure fluid transportation in industries such as hospital oxygen and beverages, food, chemical, agricultural, and industrial settings.

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.
