In order to ensure foolproof, everyone needs to grasp the material selection and construction.

The following editor will share with you on these issues and look forward to helping friends in need.
How to buy ppr tube
The ppr tube is widely used in modern home decoration, and many people will use it when decorating their new home. However, many people do not understand this type of pipe, they do not know how to buy ppr tube. Editor recommends that you use the following methods to purchase ppr tube:
1. "Look" appearance: color, good PP-R water pipe has soft and uniform color, no noise.
2. "Smell" odor: The main material of PP-R pipe is polypropylene, good pipe has no odor, and the poor one has a strange smell, it is likely to be blended with polyethylene, not polypropylene;
3. "Feel" texture: good PP-R water pipe is 100% PP-R raw material (without any additives). The texture is pure, the surface is smooth, the feel is soft, the pseudo PP-R pipe feels smooth, and generally speaking, the particles are rough It is likely that impurities have been incorporated;
4. "Pinch" hardness: PP-R tube has a considerable hardness, any tube that can be deformed casually is definitely not a PP-R tube;
5. "Quantity" wall thickness: In addition, it can be measured with a vernier caliper. Whether the wall thickness of the pipe is up to standard and uniform. Generally, good pipes are produced strictly according to the national standard, but this method requires a certain understanding of the national standard of PP-R pipes.
6. "Listening" sound: the grounding sound of PP-R pipe is dull, and the grounding sound of pseudo PP-R pipe is relatively crisp.
7. "Smash" elasticity: good PP-R tube, good "resilient", easy to smash is naturally not a good PP-R tube, but the best PP-R tube can be smashed even if the temperature is below 10 degrees.
8. "Burn" smoke smell: PP-R tube mixed with recycled plastic and other impurities in the raw material will emit black smoke and have a pungent odor. And good materials not only will not emit black smoke and no smell after burning, but the molten liquid is still very clean after burning.
When buying ppr tubes, you should avoid four misunderstandings.
Since many people do not know much about ppr tubes, they are easy to fall into some misunderstandings when buying. Some owners think that only the white tube is the best, which is a wrong understanding. At present, the colors of ppr water pipes produced by different manufacturers are different. For example, the five-star home improvement pipes of Yatong are blue, and the ppr pipes of Weixing are green. The base materials used for different colors of PPR are the same, but different color masterbatches are added according to the customer's preferences or habits during production, so the difference in color does not mean the quality of the quality.
When choosing a ppr tube, you should avoid four misunderstandings
There are many types of ppr tubes on the market today, and they are very different in use. Some are suitable for use as cold water pipes, some are suitable for use as cold water pipes, some are suitable for use as hot water pipes, and some are suitable for cold and hot water use. Everyone must read the instructions clearly when purchasing, and make targeted purchases. Of course, the raw materials used for PPR cold and hot water pipes are exactly the same. Divided into cold and hot water pipes are distinguished according to the temperature of the water that can be transported when different specifications of pipes are used. Due to the higher requirements for the delivery of hot water, the hot water pipe with the same nominal pressure (PN) is thicker than the cold water pipe. For the convenience of distinction, the hot water pipes have red coextruded strips and the cold water pipes do not.
When choosing a ppr tube, you should avoid four misunderstandings.
Some people think that the pipes and fittings do not have to be manufactured by the same manufacturer. Only the specifications can be matched. This is also a common mistake people make when purchasing ppr tubes. This is because the raw materials used by different manufacturers are somewhat different, and the production process is also different. Reliability is not guaranteed when connected, so it is generally not recommended. Everyone try to choose the same brand when choosing ppr pipes and accessories.
Four misunderstandings should be avoided when purchasing ppr tubes
Some owners only pay attention to their surface and odor when purchasing, and ignore an important detail, that is to determine their nominal pressure. The pressure conditions of the water pipes in each person's home are different, and everyone should choose the ppr water pipe specifications you need under the pressure conditions you need. PN in the pipe code represents the nominal pressure in MPa. The wall thickness of pipes with different nominal pressures is different. When selecting pipes, make sure that the nominal pressure of the pipes is not lower than the water pressure of tap water.
The above is about how to buy ppr tubes and how to avoid the four misunderstandings when purchasing ppr tubes. Let me give you a reference! In addition, everyone should also test the pressure when purchasing ppr water pipes.
