Product Introduction:

PPR is the abbreviation for Polypropylene-Random, a random copolymer of polypropylene. It is a plastic pipe product that was developed and introduced in the late 1980s and early 1990s. Thanks to its outstanding performance and wide range of applications, PPR has established a firm foothold in the plastic pipe market and is widely recognized as an environmentally friendly, green product.

Application areas:

PPR pipes are widely used in markets across various industries, including building water supply and drainage, urban and rural water supply and drainage, city gas systems, protective sheathing for power and optical cables, industrial fluid conveyance, agricultural irrigation, construction, municipal engineering, water conservancy projects, as well as agriculture and industry.

Advantages:

1: Health, hygiene, and environmental protection. Polypropylene It’s an environmentally friendly material and can be used for drinking water pipelines.

2. The joints are joined by hot-melt welding, creating a seamless, leak-proof connection. Other materials are connected using threaded fittings, which offer inferior leak resistance and also eliminate the toxicity associated with glue bonding.

3. High temperature resistance, excellent pressure resistance, and low flow resistance.

Product differentiation:

PPR pipes are divided into cold-water pipes and hot-water pipes. The key difference is that cold-water pipes have a blue marking line, while hot-water pipes have a red one. Additionally, PPR pipes are marked with designations such as S5, S4, S3.2, and S2.5. Typically, S5 and S4 are used for cold-water pipes and have thinner wall thicknesses, whereas S3.2 and S2.5 are used for hot-water pipes and have thicker wall thicknesses.

Additionally, the joints of PPR pipes utilize hot-melt technology, ensuring that the pipe ends fuse completely together. Therefore, once installed and passing the pressure test, these pipes will not leak, offering extremely high reliability.

Please note during installation:

1. When connecting PPR pipes and fittings by hot-melt welding, if flange connections or water fittings are used, it is essential to use fittings equipped with metal inserts.

2. When carrying out construction, be sure to use a reliable hot-melt tool to ensure the quality of the hot-melt process.

3. Use specialized construction materials to cut pipes; the cut edges must be smooth and free of burrs.

4. When cleaning the welding areas of pipes and fittings, make sure to keep out sand, dust, and other contaminants that could compromise the quality of the joints. Use a heating tip that matches the size of the pipe to be welded. Hot melt On the device, turn on the power to allow the heating element to reach the appropriate temperature.

5. You can use a pencil to mark the fusion depth on the pipe.

6. Place the pipe and fittings into the fusion machine and heat them for the required duration.

7. Once heating is complete, immediately remove the pipe and fitting and connect them right away. If the positions of the pipe and fitting are slightly off when they’re joined together, you can make minor adjustments within a certain time frame—but the twisting angle must not exceed five degrees.

8. After the connection is complete, be sure to hold the pipe and fittings firmly with your hands, allowing them sufficient time to cool down. Once they’ve cooled to a certain degree, you can release your grip and then proceed to install the next pipe.
